Okay, I'm trying very hard to keep an eye on my box, particularly after
reading the horror story about grackles snatching the baby blues! But papa blue
just doesn't want to cooperate. Yesterday I walked up to the box, talking the
whole way so mama would know I was coming. I started to get really concerned
when I didn't see papa nearby, mama didn't fly out of the box, and there was
complete silence. After quickly checking for papa once again, I opened up the
box to have a look and saw that there was a nestful of quietly slumbering (or 'possuming!)
babies and then here comes daddy, diving at my head!!! I quickly shut the box
and got out of there, so I didn't get to see if all 6 of the eggs had hatched -
from the looks of it, I would say yes. My question - have any of you actually
been hit by the divebombers? Do you get out of there when they start diving at
you or do you try to finish up your monitoring? Will they every STOP?! LOL
And thanks to those who gave suggestions on non-toxic poisons. I went out
there the other evening with my combo of water and dish detergent and went to
work on those darn bagworms. I at least got them away from my doors and off the
porch and the numbers seem to be dwindling (probably drowning with all this rain
we've been having!!).

They won't hurt you. They are definitely communicating! Still, when I was
being dived at, I wore a hat.
Right now, I'm feeding mealworms, and they know me, so they don't dive at me
at all. When I whistle on the way to the feeder, they both fly there even before
I arrive, leaving to a nearby branch to give me time to put the mealworms in the
feeder, then rushing back as soon as I go on to their nestbox to monitor. They
look over at me, but are not at all bothered by me.
It's also interesting to me that, although this female is almost all brown, a
different coloring from any I've had nesting here prior to this, both of this
pair flew directly to the feeder the first time I put out mealworms, which was
the first day one of them showed at the nestbox, and before they began
nestbuilding. I guessed that one or both was fledged from that same nestbox last
year or the year before. The first bluebirds I had here four years ago took two
weeks of my constant efforts before they took their first mealworm.

I know that they can be disconcerting when they're trying to defend their
nest. But you can safely ignore them. Ya gotta keep in mind that they don't come
equipped with talons, a hooked beak, or weigh-in at 10+ kilos...(:-)!
Yes, I've had a few actually tap me...kinda like getting slapped by a
flutterby. And not all that dangerous or damaging. Don't worry about them. As
passionately vicious as they appear, they're just trying to do their best to
defend their nest. But you'll find that it's all flutter and chirping, and very
little blood & guts...(:-)!

Dina,
I have never been hit by a divebombing Bluebird or Tree Swallow. (The Bluebirds
here rarely come at me; the swallows always do.) Two kinds of birds have
actually hit me - Common Terns and Brown Thrashers. The Terns did not draw blood
from my scalp, but the Thrashers did several times, and right in my own front
yard. The scariest bombers are the Black Skimmers, though they always veer off
at the last millisecond. I'm thankful that they do. They're crow-sized, and they
have bills like big stilettoes. (sp?) (The Terns and the Skimmers don't bother
you unless you get too
close to their nestings in the dunes.) Bruce Burdett, SW NH

Do you know if an EABL will use lethal force on another EABL, its young, or
eggs? If yes, is this a common or rare occurrence? How about HOSP versus HOSP
aggression?
Just curious.

Keith Kridler Mt. Pleasant, Texas
Many people are seeing some pretty horrific fights between adult bluebirds over
nest sites. These normally occur outside of the box and one or the other can
easily escape. Bluebirds are known to be able to remove their own unhatched eggs
or those of other birds. They are known to kill and remove young of other
species, they can remove their own dead young up to about 3/4 their own weight.
Survival of the fittest would encourage the most dominate pair in the area to
hold or "take away" the best nest sites from those birds less experienced or too
old or too young.
I feel certain one of the adult female bluebirds killed in a PVC box last
year was from a second pair of bluebirds seen fighting them for control of the
new box. I drove by everyday and observed only bluebirds fighting for this site
and after removing the dead bird only bluebirds nested within several miles of
this site for the entire season and the box was too deep for starlings to reach.
(I have fledged 7 bluebirds a couple of times from 4" PVC nestboxes.)
Patricia Gowaty, one of the premiere bluebird behavioral experts feels that
bluebirds can and do kill each other on occasion. This is probably very rare
where nest sites are numerous and bluebird populations are low but in high
concentrations these birds are forced to nest in horrible locations!
Example: Why you should leave eggs in nestboxes longer! You check a box on
April 1 and find a complete nest. April 8 you have five eggs with female
incubating, same on the 15 and same on the 22. Toss the eggs and nest on the 29
and wait for bluebirds to renest. What if anything removed the five eggs 30
minutes after you checked the box on the 8th. On the 9th another bluebird began
laying eggs and was incubating when you checked on the 15th. There is a
possibility that 15 eggs could have been removed and re-laid by three different
female bluebirds and you would NEVER have known these were new eggs. This is one
of the reasons where bluebirds are numerous that you need to check your boxes
twice a week!
IF you decide to remove "abandoned eggs" only remove one and break it and
look at it closely to determine if you have made a horrible accounting error or
the birds have renested and you were not aware! You don't want to know how many
accounting errors I have made when I first began checking boxes! KK

Keith,
Thanks for the information.
Another question. When bluebirds remove eggs from a nest box, do they merely
roll them out the entrance hole, or do they pierce the shell and carry them in
flight away from the nest box, or both? There is nothing like a little forensic
evidence to reconstruct the crime scene! I'll assume that HOSP's will behave
toward their own species as they do toward another species.
I also use PVC (4" diameter) nest boxes. The number of fledglings per box has
been consistent at 4 over the past 2.5 years. Wow, seven fledglings in a 4" pipe
- that bluebird pair definitely had type A personalities. I'll be content with
4, that seems to be just the right number.
I have never had a problem with eggs not hatching on time, but who knows what
will happen next. I'll remember your advice if I ever run into this problem.

Throughout the winter we had a large flock of bluebirds that would use a
mealworm feeder daily. As expected, sometime in February, the dominant pair
claimed the backyard nestbox and chased the other bluebirds out of their
territory. All except for one female that they allowed to remain. I figured this
female must not have found a mate, as she continued to hang out in the yard
throughout the first nesting, although she never assisted with the task. Even
after the first clutch of eggs hatched and the nesting pair was taking mealworms
to the nestlings, they still allowed the other female to sit on the feeder with
them. I could tell which one she was, as she never gathered any worms in
quantity, but just ate them one at a time.
A couple of weeks ago, (after the first clutch fledged but before they
returned to the yard), I noticed the 2 females and the male on the mealworm
feeder, and all 3 were gathering mealworms in their beaks! The lone female would
then fly toward the front of the house, and return empty-beaked to repeat. She
must have nestlings to feed! I used a cell phone and positioned myself one
streeet over in the general direction she headed, then called my husband to
signal that he could put out mealworms and "call" the bluebirds. We waited until
he saw the lone female take a mouthful of worms and he told me she was on the
way! I was able to track her three street over this way, but then lost her.
Interesting!
Any ideas on why this female is being allowed in the territory of the
backyard nesting pair and all other bluebirds were chased away?

I've been impatiently waiting for Mr. and Mrs. Blue to begin a second nesting
(first babies fledged May 7th). I've seen them around the nestbox quite often,
but nest building hasn't begun.
This morning when I awoke, both adults were in and out of the nestbox
numerous times, so I took that as a very good sign that nest-building would soon
begin in earnest again.
A bit later this morning, I noticed a commotion outside my kitchen window. It
was two male bluebirds, fighting furiously, for the attention of the one female,
who was frantically chattering and wing-waving nearby as if to tell them to
"Knock it off, guys! Let ME choose who I want to make babies with!" By this time
I was outside, frantically snapping photos, and also tried to dissuade them from
fighting by throwing bits of bark mulch at them, but they paid me no mind at all
and let me get amazingly close. At some point, they flew off, only to return and
fight some more a half-hour later or so. At some point the fight broke up
(thankfully), and they all flew off.
Now, about an hour after all the excitement, one male is sitting in the tree
by the nestbox singing and calling. Every time the female comes close, he
follows her all over the trees or wherever she flies. He keeps going into the
nestbox to entice her. I have seen her on top of it, but haven't seen her go
inside since the "war" this morning. I'm almost wondering if her "favorite guy",
the one she went in and out of the nestbox with this morning, lost the battle
for her affections, but she's not so sure if she likes this new suitor as much!
I am sure I am anthropomorphizing heavily, but this has certainly been an
interesting morning! Would appreciate any comments/theories from the more
experienced bluebirders on the list.
Also have a question about the fledglings. I saw one with "dad" in the
birdbath a week after fledging, and have seen no more since. Does that mean they
are just doing their own thing elsewhere now, or is it a sign that they did not
make it? We had some cold nights here last week - the lowest temp we had was 39,
so nothing below freezing, and no rain.
Thanks all!

Hi TomGary, mY guess is that this lone female that is allowed to stay in the
area of a pairs nest is that its a young from one of their previous nests. I've
seen them help build nests and help feed young birds in the next nest. I've seen
two adult female EABL fight over territory. They tumble on the ground clenching
each other with their legs and feet. Don't understand how they determine who won
but eventually they break up and one heads away and the other stays. Males
fighting for territory is why they don't nest close together. One time when two
pair nested about 100 ft apart, there was a face off in the middle of the street
between the two box locations. The two males faced each other about 6-8 inches
apart and circled each other like a dance. They kept this up for several minutes
and finally flew back toward their own nest locations. What made the difference
was the nest starts were about a week and a half apart when neither had chicks
to feed so this may have lowered competition for the moment. This pair of
nesters fed in different directions so didn't run into each other very often.
Both had successful nests. Joe Huber venice, Fl,

Subject: "Tight" sitters?
To: Bluebird-l"at"cornell.edu
I've been reading on this list how some have experienced a female bluebird
holding her ground, or "sitting tight" when the box is checked while incubating.
Although I only have five boxes and 3 years under my belt, I've never
experienced this. Even the backyard, mealworm-fed blues are wary and leave the
box whenever I get within ten feet of it. They don't seem to be too concerned,
however, and just sit a little way off before returning to the nest quickly.
This year, as I've written on this list, I've had 5 other species nexting in the
house foundational planting (one actually in the
garage.) I've noticed a big difference in each of their tolerances for people
nearby while incubating.
First, the Robin. She was quite skittish nesting at the front door and even
caused two of her eggs to fall out of the nest in her initally frantic efforts
to flee. However, she quickly grew accustomed to people at the front door (she
was two feet away, and then sat tight unless someone poked their head into the
Juniper.
The Mourning Doves in the garage are nesting at eye level (my eye level, not
Bruce's legendary level). This large bird will sit and pretend she's invisible
unless a noise or unexpected moment spooks her. Then she flies around and around
the garage (I thinkg she's trying to deliberately poop on the offender!) until
sh settles down again.
I don't think the Chipping Sparrow could be pried off her nest with a
crowbar! Her nest is in the top two inches of an Abelia bush righ next to the
front walk. It gets constant traffic. I've been within an inch of her and she
still stays put!
The other extreme is the House Finch. Nesting in a Juniper on the corner of
the house, they have experienced Cowbird brood parasitism, and have lost two of
their five eggs (I don't know to what). No one can get within twenty feet of the
tree within them panicing, leaving the tree in a twitter and sitting on the roof
top making all kinds of noice.
My question is this. Obviously, there are differences in individuals among
birds. But, is there a species generalization? Perhaps based upon the style of
nest, location, etc?
Any thoughts?

To: BLUEBIRD BLUEBIRD-L"at"cornell.edu
Hi all,
I found 6 'fresh' feathers in an empty EABL nest. With the amount of orange
on the feathers they just had to be an adult EABL. I found the feathers two
weeks ago on my Indiana nestbox trail as I cleaned out the old nest. The
feathers were too brightly colored to have been part of the used nest. The 4
nestlings were gone as I expected. Last weekend I watched to see both the adults
and fledglings without much success. The fledglings were well hidden and
inclimate weather kept all birds from moving about much.
This weekend was a different story; just absolutely beautiful weather the
majority of the time. All 4 fledglings and both adults were seen at a mealie
feeder and a birdbath. They just love to mix it up in a bath.
Were they marking the box in their territory with the feathers?. I had never
seen the feather thing before. This past week she built a new nest in a nestbox
about 50 yards away from the box which was used for the first brood. Yesterday,
the 4th egg was layed.
Finally, I am up to 13 nestboxes with TRES in them. I have only had at most 1
TRES nest in any previous year. The EABL fledge and the TRES move in immediately
before I can even clean out the old EABL. The TRES even removed some HOSP nest
material before building on top of what was left. Looks like I am going to have
to do the pairing thing otherwise I may loose my 2nd EABL brood each year.
Have a good day

Hi Doc (Bob). I pair *ALL* my boxes. They are 22' apart as a pair, and each
pair is at least 300' away from the other pair. This is true for boxes at home
and in the park. The EABL and TRES seem to like living as neighbors, and often I
see the EABL perching on the TRES box, and vice-versa. As Bruce mentioned, I
often see many TRES around a single site. Only two are the parents-to-be, while
the others are single TRES, just there for company... TRES are very gutsy little
birds, and will allow me to get very close to them. If one is sitting on her
eggs, she will not leave even when I open the box. Generally, I leave them alone
if I see them sitting on eggs.

I hope that was not a stupid question. Last night between 8:30 - 9, I was

sitting on the perch outside the nest box. I have seen him throughout the day
fly to the perch to bring food. The babies inside will be a week old this
weekend and I have seen the mother inside with them while the dad brings the
food.
Back to my story....Last night he (?) sat on the perch for several minutes. I
was watching and waiting for him to fly away before I went back inside my

My experience is that bluebirds will defend their territory. Despite reports
from others, my paired boxes have not resulted in both TRES and EABL at the same
time. The bluebirds, both last year and this year, have driven off TRES who
showed interest in the paired box.
Keith Kridler has frequently suggested extra boxes to deal with competition,
including that from HOSP (a trap box), but I have not gone that route either. I
have stuck with two boxes, about 12 feet apart, one about 20 feet from the tree
line (a Peterson, which the bluebirds invariably choose) and a NABS box which is
12 feet further from the tree line.
I have two additional paired boxes at 100 yard intervals. Currently, I have
EABL only in the Peterson closest to the tree line. Figure that!

I have never checked inside at night, but the books say that the male perches
in a nearby tree. The female stays with the nestlings, at least until they have

When I put my boxes at 12' apart I got either EABL or TRES and never both.
When I increased the distance to 22' I am getting many sites with both EABL and
TRES... Also, at home I use the pairing idea for trapping HOSP, whose wings I
trim and let them loose in our yard. I see these HOSP all summer long... Right
now at home I also have a pair of boxes with EABL and TRES! At home I have two
additional pairs of EABL. All four pairs (3 EABL and one TRES) are happy
building nests now. The EABL are on their second nesting.
In the park there are more nests, and I plan to visit there sometime later
this week.

Hi All, We have some boxes placed at my in-laws. There is a bluebird nest
with 4 eggs and a TRES nest with 6 eggs. The male bluebird flies to the picture
window all day long and just looks inside. He doesn't peck at the glass. He just
sits there and looks inside. My mother-in-law loves seeing him up so close. We
thought that he saw his reflection but wouldn't he peck at the glass? What do
you think is going on with him? Patty in Fairview, WV

Hi Patty, This happens a lot, and it is believed the bluebird sees his
reflection and is trying to chase away a competitor. This may go on for weeks.
YOu can stop this by placing something inside the glass where he flies up to the
window. He may give it up once serious feeding starts ,but you can't be sure. On
a golf course where I once had nest boxes there was a bluebird that kept flying
up to mirrors on owners truck . He kept it up for weeks. Messed up mirrors big
time every day. Didn't matter if truck was parked in different place,the bird
found it. Joe Huber, Venice, Fl.

We mowed our back yard field yesterday and left a TRES box standing square in
the middle of it - right where it was before the mowing. This morning I caught
my front yard EABLs attacking the living daylights out of the TRES in the
backyard. I mean, both male and female had the TRES pinned down to the ground!!
Now this TRES nest has 3 or 4 eggs - so it is well established. Usually our
EABLs don't like even TRES nesting within view of their box in the front yard.
Well, they seemed to do fine with it in view this year -but we think when we
mowed the box "stood" out more visually -even though the box is 200' away.
They've been attacking the box all day long! The EABL have 5 nice warm eggs -
so not like they are looking for another nesting box. We even moved the TRES box
out of sight of the EABL box. Which by the way was something. Thom picked up the
box on the pole and moved it while the mom stayed right on her eggs.
Both T and I decided it was the female instigating the whole thing because
she'll sit there near the TRES box wing-waving up a storm and we both feel like
she is "making" him do the dirty work by attacking!
So far the TRES have persevered. :-) H

Diane,
I have a similar situation with a male in my backyard with a second mate. His
first mate was trapped and killed by a HOSP inside this particular box. He too
exhibited the behavior you described. I also have never seen a BB act so
aggressive towards any HOSP he encounters. I've seen him physically attack (and
I mean attack!) a couple of male HOSP who happened to wander into the general
vicinity. Both times, the HOSP screeched and flew out of the yard as fast as
they could. Boy did that make my heart glad!! I think the first experience
taught him the necessity to be extra vigilant and cautious.

Hi all,
We're on our second nesting in our sole backyard bluebird box, and Mama is
currently incubating the eggs. It's been really hot this week in NC (95+ highs),
and I've noticed that she is sticking her head out of the box for long periods
of time. Is this how she regulates her heat? It would seem so, especially since
she didn't do this nearly so often with the first nesting.
We see a couple of the fledglings from the first nesting cycle around our
backyard nearly every day, drinking from and bathing in the birdbath, hunting,
and perching, and it's a wonderful sight. Even though we're doing this on a very
small scale, I am thankful for every new bluebird we're able to help into the
world!
Happy bluebirding,

Hi Emily,
I understand that a female will use her wings to fan her nest if it is too
hot. I don't know where she would be while fanning - perhaps this varys. I don't
know how long she could be effective with this.
It is not unusual for the female to spend long periods off the nest and out
of the nestbox on hot days.
Have you thought about shading the nestbox? Various things can be used to
shade the box like an umbrella, leafy limbs, etc. I have very large plywood
shade roofs that I tie on to existing roofs. The shade roof is separated from
the nestbox roof by small wooden blocks which keep the two roofs about and inch
apart. The idea here is to slow down or stop the trasfer of heat from the shade
roof through the separator blocks to the nestbox roof. A large shade roof can be
positioned to shade the walls of the nestbox, too.
If you try shading make sure that whatever method you use to keep the shade
in place does not assist predators.

Tom,
I have never before heard of the hens fanning the chicks with her wings. It may
be possible. I have heard of and even seen birds that were brooding chicks fly
down to water, wet their breasts and return to cool the chicks this way. I've
never heard it mentioned specifically that bluebirds do this, but it may be
possible if they are near water.

Well, I went to the archives and read all about window strikes, and I really
have a crazy one! I was very successful (I think) as the first nest of 5 has
fledged. I have yet to see babies fledge, though both this year and last, the
pair continually finds food and flies into the woods, so they must be feeding. I
am guessing the 5 are out there somewhere as of a week ago.
Well, the male has been hitting every window in my house for the last two
weeks. We have a large log house with a walkout in front, so there is no way I
am going to put anything in the windows. (I can't reach the high ones from
inside or out anyway). The male goes to the top of the window, taps it, and
gently flutters down to the wide ledge where he leaves me a record of his
presence. He does the garage, picture windows, circle top, bedroom windows,
solarium etc. He isn't fussy. Luckily I have no neighbors, so it is only us. I
am an early riser, and I love the birds keeping me company all over my yard. So
I am not too concerned. The male does not injure himself and you tell me, but I
am guessing he is either defending his territory or gathering insects off my
windows. I assume the female will be laying her second clutch soon, so hopefully
this will end. It didn't start until the young were quite large.....
Any comments would be appreciated.

Join the club, Jeanne. The window-banger Robin that I first mentioned back in
late April is still at it today - what's this, June 18? - usually starting at
about 6:00 AM. Most of the time it's my woodshop window, down at ground level.
The window has a huge Rhododendron right outside, so he has a place to sit and
contemplate his next moves.
I have no idea why they do this, though I've heard a number of theories. We
must remember that these birds have brains about the size of a pea, so there's
not much room up there for complex thoughts, reasoning, contemplation,
pros-and-cons, and so forth. I doubt that this Robin has any interest in my
power tools, per se. My best guess is that the bird himself has no idea why he
does it; he just does it. Our cat used to be fascinated by bird-watching shows
on TV, but she had a relatively enormous brain, (though of course, Wendell, not
nearly as big as mine.) Bruce Burdett, SW NH

Just wanted to let ya'll know what's going on around here. I am expecting 4
eggs to hatch over the next several days. I checked the box yesterday and mama
swooped down at me several times. This is the 3rd time I have had eggs this
season, but the first time with this female. I have never had any of the other
bb's swoop me. In fact even with this female, you could actually get close to
her without her flying away and she has watched me before on several occasions
checking the box. Maybe she knows it is time for them to hatch and is getting
"protective". That is fine with me.
Dad has not been around as much lately. Not even for mealworms. Last week I
saw him checking out another nestbox several times. When I did not see him any
longer I assumbed something bad had happened or he had found another "lady" and
was with her.
The other times I had babies the male and female stayed around--until the
female died. Anyway, I saw him briefly yesterday morning and several times this
morning. He was checking out the other nestbox again.
I would think it would be to late for them to nest again, but who knows.
By the way, once a baby has left the next how long before they will start a
family themselves?

Kim,et al,
I believe that Bluebirds produce offspring the summer after the one when they
fledge, though I hope someone will correct me if they know better. I say that
partly because all the adult Bluebirds I ever see are either mated or have lost
a mate. Tree Swallows, on the other hand, always seem to have a bunch of unmated
immatures hanging around in little squadrons and joining the nesting pairs in
their strafing attacks.

Hi,
I had a somewhat similar incident last year when the last fledgling of the
second clutch was coaxed from the box by the adults and a fledgling from the
first clutch. The parents and older siblings kept flying down to the baby,
coaxing it from the lawn to a small bush, but the fledgling could only fly a
couple of feet.
When it went to an area where I had seen copperheads, I decided to intervene
and place the frightened fledgling in a tree. The adults did not appreciate my
efforts and dive-bombed me until I left the baby on a low branch. The adults
then coaxed the fledgling to a large tree in my neighbor's yard where it climbed
the trunk like a little nuthatch or woodpecker!
Do you suppose your baby birds were frightened into premature fledging, and
the parents are just trying to encourage them to move to a safer place?

My backyard bluebird pair has begun their third nesting in a half formed nest
cup. There is a well formed front half of the nest and the back is almost bare.
I looked at the numbers from their previous nestings this year to see if perhaps
there was less time between building and laying, but there wasn't. The numbers
looked interesting though - they are in the table below. It seems this pair
likes the number 17!
(Couldn't get the table in the email without using rich text - sorry in
advance to those who cannot read it)
There was no HOSP pressure or anything obviously causing the bluebird to be
unable to build - and the Lord knows there's an abundance of dead grass with
this drought! What else could cause the partial nest? (Perhaps she's tired!)
Should I try to add grass to the bare bottom and back, or leave
it alone?

Date: Sun, 14 Jul 2002 00:09:20 -0500
Greetings all,
Late this spring I shared the saga of my whacked-out female EAstern BLuebird
from last summer. She built three nests and for her fourth she removed the
feathers from an unused TREe Swallow nest and then reshaped the cup. (The TRES
had built two nests, but used only one.) Of course, the female EABL used only
one of the nests. Her mate was taken by a hawk (probably Cooper's) when she had
laid only three eggs. She continued laying eggs and fended for herself quite
nicely... until another male showed up. Just before the five eggs were supposed
to hatch, they disappeared. The female and her new male went on with their lives
and fledged four of their own.
So, this year, I was hoping to get the female back... but no. A different
female showed up (I can't tell about males) and they went about their business
(although nesting started a bit late due to crappy weather). She laid four eggs,
they hatched and the night before they were to fledge, the female disappeared.
The male continued... and the young ones have spent a lot of time in our yard (a
first for me). They fledged Wednesday, June 19, and as of Sunday, 6/23, all four
were fine. Then they moved out of the yard towards the woods that the EABLs
usually move to after fledging.
A female was here by herself on 6/30 and on Monday, 7/1, the male and female
were here pretty much all day. No juveniles in sight! (Oh no, are they really
able to care for themselves already?) So, I'm wondering if this is last year's
female... because she has the same very pale coloring. Lo and behold, she came
to the mealworm dish when I whistled! Well, the next day (7/2), the male must've
felt like he'd won the female over and it was okay to reveal his baggage.... two
juveniles showed up. (For those keeping track, that means two out of four died
within 9 days. I knew it was going to be tough when, the day after they fledged,
I watched the male take on Blue Jays by himself.... leaving the fledglings to
their own devices while he went after them.) Since then, the two juveniles and
the two adults have been hanging out around the yard, so I've been able to watch
their behavior closely. The juvenile male is quite aggressive and digs in to
help himself to mealworms. The juvenile female will fly to the mealworm feeder
and beg someone to feed her! She's even begged her brother to feed her. Hope she
makes it.
Anyway, I've never had a second nesting in my yard after a successful first
nesting. (I think I usually get EABL's second nesting attempts.) So, after
quickly wooing the female she proceeded to build three nests starting on 7/3.
She is now incubating four eggs.
What I miss is the rapport between the male and female that I'm accustomed to
seeing. The male was all-consumed with the two kids and isn't feeding the female
AT ALL. (Although the last couple days, I don't see him feeding the kids either.
Today, every now and then he'd chirp at them, but didn't feed them or fly to
them.) The male and female don't do the wing-waves or chitter-chatter talking
with each other. I know she is tough from watching her last year, but is this
how a female is typically treated during a second nesting? The only deference he
pays her is that she gets first dibs on the mealworms... he doesn't feed her
like I'm used to seeing (although during that quick wooing stage he did), but he
lowers his head and lets her eat. (She's taken on the juveniles a couple times,
taking them to the ground and pouncing on their backs when they got in her way.)
Anyway, for those of you who have multiple nestings in your yards and have
been able to observe them, is this normal behavior? I'm kind of concerned
because we'll be on vacation shortly after the eggs hatch until probably
fledging and I won't be here to help if there is trouble... because right now
I'm not expecting the male to help feed her or the nestlings? It seems like as
of today he might really be weening the kids, so he should be available to feed
new nestlings... but dang-it, why can't he at least get a little munchy for the
female?

Hi all,
We put up our first 2 bluebird houses this spring and have had 3 nests
between them, but we hadn't seen the babies fledge and didn't know if any
survived. We saw the parents flying up to a nearby tree with bugs for a couple
of days after the first nestlings disappeared around June 1st, so we were
hopeful.
Last weekend, near sunset, we noticed groups of 3-6 birds perching in the
tops of trees and on the TV antenna/tower that would repeatedly fly out a short
distance and feed on insects in mid-air and return to the tree top. We watched
without moving around and they stayed at it for about an hour, high overhead.
Although there was an adult bluebird with them, this wasn't the typical
bluebird feeding behavior and I've been wondering what those birds were.
Yesterday, with an overcast sky just before sunset we were able to see blue
feathers on the speckled juveniles--and they are definitely bluebirds. The
oldest would have fledged about 7 weeks ago, the first fledge from the second
nestbox would have been about 5 weeks ago. In watching for a couple of hours, I
finally saw 2 of them briefly go to the ground for bugs (halfway across my
neighbor's yard). They didn't seem to be feeding as much as on Sunday, but were
catching bugs in mid-air at tree-top height more often than going to the ground
from a 10-15' high perch.
These birds seem shy and quickly leave for the far side of our neighbor’s
yard if they see us walking around with binoculars, following and watching them.
Monday evening, I did get a glimpse of 3 on top of the empty nestbox, after
sunset, as it started to get dark. One poked his head inside to check it out.
They stayed for a minute or two, then flew off. Just exploring, I guess.
Are my young bluebirds unusual or did I just happen to observe less-common
behaviors? I would speculate that bluebirds that are accustomed to human
presence and perhaps a regular supply of mealworms tend to stay lower and feed
from the ground, and hence are easier to spot than my high-fliers.
We have one adult male that sits by himself on the antenna or treetop and
calls. Is he looking for a mate this late in the summer? The 2 boxes are both
empty.

Linda Violett - Yorba Linda, Calif.
Since the season is ending and the List is slow, I'd like to know how many
others are seeing three bluebird adults feeding a bluebird clutch and whether
the occurrences could be the result of nestbox shortages. This year on my
established trail, there was more competition for nestboxes and there were three
sites with adult "helpers."
If adult "helpers" are result of limited nesting sites, perhaps bluebirds
could develop colonial nesting habits similar to tree swallows.
On the flip side, it is just as important to know whether monitors with
plenty of vacant boxes (lack of nestbox competition) are seeing adult bluebirds
who are helping the nesting pair.

This is the first year I have had EABL's successfully fledge more than once.
Since I have been feeding mealworms I have been able to watch behavior. Parents
fed fledglings for a couple of weeks and then babies came to feeder with parents
and fed themselves. As soon as babies were independent the parents laid three
more eggs. As soon as these eggs hatched the parents have been very aggressive
towards first babies. Will not let them feed at feeder. Is this typical. I have
always heard the whole family sticks together and the first babies even help
feed new babies. I am interested if any others have information. Thanks. Pam in

Pam,
I, too, fed mealies in my backyard and got to watch a pair of EABL fledged two
clutch. I never saw the first set of fledglings ever come the mealworm feeder. I
did see the parents ferry mealies up to the tops of trees for a while, but they
quickly got involved with the second brood. I have seen the second clutch
fledglings coming to the feeder. (I assume of course, since these are not
banded!) Sometimes they are with the parents, and sometimes by themselves, or
alone. Who knows, maybe these are a few of the first clutch fledglings coming
around!? I am looking forward to the whole family hanging around the yard all
winter. Hopefully this will lead to more pairs nesting next season. This was my
first year with a trail: fifteen boxes, 22 EABL fledged from four boxes. I'd
like to see six of seven boxes used next year!! Phil Kenny Vienna, VA
This is the first year I have had EABL's successfully fledge more than once.
Since I have been feeding mealworms I have been able to watch behavior. Parents
fed fledglings for a couple of weeks and then babies came to feeder with parents
and fed themselves. As soon as babies were independent the parents laid three
more eggs. As soon as these eggs hatched the parents have been very aggressive
towards first babies. Will not let them feed at feeder. Is this typical. I have
always heard the whole family sticks together and the first babies even help
feed new babies. I am interested if any others have information. Thanks.

Pam,
The behavior you described is pretty typical of what we've seen with our
backyard pair. It is typically dad that's most agressive with the "old" babies.
I've always attributed it to him saying "you're big enough to hunt your own
food". Most of the time our "old" babies just wait for an opening and feed
anyway. We have seen them "help out" with the next nestlings, but dad still
tries to run them off.

Hi Pam, what you describe in terms of the parents kicking out the 3-4 wk old
fledged babies is far more common then them sticking around like a big family
helping to feed the young 'uns........ In fact, most of us probably have never
seen the latter happen. I sure haven't!
However, once autumn rolls in and it gets colder, the family including those
previously fledged will often meet up and spend the winter in a family group.
They'll all come feed for mealworms, suet, etc. But once spring begins, the
parents will kick all the fledglings out. They'll have to go establish their own
territories. :-) H

My observations with western bluebirds mirror Evelyn's experience: The
family stays together as a unit during their first and subsequent clutches.
In addition, I frequently observed fledglings from first clutches feeding the
second clutches. After the second clutch fledges, sometimes an older first
clutch chick will seem to "fledgling-sit" the newly-fledged youngsters. They
will fly over and sit on a nearby branch watching (overseeing?) the youngsters
for a couple of minutes, but not as part of the tight fuzzy clutch bunch.
In warm (hot) So. Calif., we have western bluebirds year around and after the
last clutch of the family gains flight experience, they are seen less and less
at the nestbox sites until there is only a random bluebird siting during my
trail tours during the fall months of Sept/Oct/Nov.

Dear BB Enthusiasts,
I have had the same little family of BBs in my yard since the summer: One
female, a male, and a juvenile. I've seen other BBs passing through, but they
don't stay. Is this because this little family has claimed my yard as theirs? I
work out of my home and have a clear view of my bird feeding station from my
drafting table, so I see them come and go all day. They are the first bids to
show up at the feeding station in the morning. They eat peanut butter suet from
the window sill and check out the BB feeder for mealies. I've seen other BBs at
the suet feeder down by the pond, but they don't come up to the feeding station
at the house, where my 3 little BBs hang out
Trying to get my neighbors interested in putting up BB feeders and birdboxes
-- we have lots of BBs out here!! Sent out flyers with BB info., asked neighbors
to contact me by email, only got two responses out of 25 flyers. The flyers were
great! Plan to start a web site, even though I got little response. I will ask
the Home Owners Association to include our web site address in their literature.
This is rural TN, and these people just aren't environmentally conscious, or
bird conscious. Any suggestions?!

Hi Talia,
Sounds like you got the BB bug, and that you want ...to share... your
enjoyment of Bluebirds. And you have a good start.
Since I am new and also excited about helping the birds and my community, I
would first suggest..."Do what makes you happy to do." Certainly keep in
mind what the birds need, but don't just make lists and then think you have to
do everything...unless you want to... and can handle the work.
Like a quote on my web site, which I still don't know who said it, but it is
..A Goal is only a wish if you don't have a plan. So what do ..you.. want to do?
List all you can think of, but pick only about six items to really work on.
Sending the papers to your neighbors was great. But did you ask that they
..write.. back or ..e-mail.. back? Makes a big difference. Writing means they
have to find paper, envelopes, stamps, and then mail it besides writing what
they want. An e-mail is just a click of a Reply button.
But to start you did get two out of 25, and that is wonderful. Now work with
just those two people to get them started with the information they need. Books,
BB Box, or just a feeder, visit their yard. They may have a neighbor they will
bring into the group. Once they are satisfied reach out again. It is not that
your ideas will be ..all successful.. or that you then will think you have
failed. Each thing you do is a success even if you don't go on. So you can only
be successful.
As to your Web Site, if ...you... want to do one.... then do it. It is mainly
for you, and because you want to share. If other people do not want to help, or
look, or comment, that should not interfere with your ideas and happiness.
Talia....Go for it! Know you tried to do a good job, and you probably will.
And you are certainly far ahead of those who did not try .. to do, or share.

Dear BB Enthusiasts,
The little female BB and family has been staying in my yard since summer.
Every morning for months now, she pecks hard on the south bathroom window. This
window gets full south sun. The BBs live in this area of my yard (very large
side yard, which get full unobstructed south sun). This small south window has
orchids growing in it, so no chance the BBs will hurt themselves hitting it.
They don't, but the female comes every morning first thing and bangs on it hard
and loud -- I see her do it. I rush to the window, and there she is banging away
looking right at me. What does this mean?? What is she trying to tell me --
"We're ready for breakfast, get your _ _ _ out here and put mealies in my
feeder"? I am curious why she does this. I do hurry up and put mealies out as
soon as she bangs. I'm not pulling your leg, I swear it. Oh, and these BBs are
not so frightened of me anymore. When I walk out to fill feeders they fly off,
but don't go as far as they used to, in fact not far at all, and sit there and
wait for me to finish.

Very simple. they associate you feeding them with this behaviour, Somewhere

it still works for them so they keep doing it. You probably just used to feed

If I'm not mistaken, the little lady may also be trying to defend her
territory from the intruder that she sees in the window. Females are territorial
with other females and males take care chasing off other males.
I've had a similar experience which was my "first introduction" to the
bluebird world and this list. I was concerned for the birds safety. First thing
every a.m.... knock, knock, knock on my BEDROOM window (no more sleeping in on
the weekends!). I now keep my windows filthy (or keep a can of Xmas window snow
spray handly) to minimize the window's reflections - if needed.
Good luck!

Hi Talia,
We have a male bluebird who bats our basement patio door constantly (faces
East-SE). He started the day we put up the box (2/14/02) in the backyard and the
pair claimed it as their own. He has done this every day ever since, except
during really cold or wet weather. He also bats my next door neighbor's window.
And another favorite window 4 houses away. He will perch on the window ledge and
just stare at himself, then fly up and bam, bam, bam, for hours at a time. It's
definitely his territory. When it started I was afraid he would get hurt. I
tried several things, and two things worked (sort of). But now we just watch him
and enjoy his silly antics. 1. I smeared toothpaste with a wet sponge all over
the patio door to stop the reflection (easy to wash off, won't scratch glass).
But he just moved to other windows, so I washed it off and let him have at it.
2. On our palladian window, I taped inside a life-size picture of a barred owl.
We took it down after 24 hours, because we were afraid the pair would abandon.
But he never bothered that particular window again (luck or learning?). My
biggest concern now is that he will be so preoccupied that a predator will take
advantage. But we obviously cannot stop this behavior in this bird. Fortunately,
my neighbors have not complained. The pair has stayed all winter, defended their
territory, and frequently spend time in the nestbox. I do offer them mealworms
every morning, and we see the same pair, with several of last summer's fledges,
every day. When I bring out mealworms, I whistle and they all fly in. They are
very polite; they don't bang the windows, but they do stare in at us, waiting.
If you think your bird has learned to be fed by banging on the window, you might
want to try conditioning with a whistle instead. But maybe its just territorial
behavior. Good Luck, and enjoy your bluebirds! Barbara Ellicott City, MD

I have received some good posts about it. One said that a female had been
killed and the male got another mate and she took out the nesting material and
built her own. Another said that it was probably material put in there by
another bird and she was removing it. Then, another said that the female
sometimes attempts building before she makes up her mind to accept the one that
the male has chosen.

Thanks Larry you are right on the ducks! There probably are a few more species
that occasionally find and use a "cavity". Most of these smaller ones rely on
cavities excavated by Flickers or Pileated woodpeckers since the Ivory Bills are
extinct....We should ALL be placing some bigger nestboxes in and around our
area....Shawn and I placed five more this past weekend...
Re:Weird; I have placed video cameras on nestboxes while the bluebirds are
building and you will see that just like "contractors" that the bluebirds often
carry in a piece of building material that was cut and fit or looked like it
would fit and be "perfect" out in the field and then it just does not fit in the
box.....They carry it back out of the box to find one that fits....I have
watched the female carry in grass and the male remove it......Everyone should
get a tripod and a camera set up to watch this activity at least once......You
fast forward and back up and watch every blade of grass being carried in....I
had a complete nest of Tufted titmice ready for eggs...I added another box about
20 feet away, checked the "complete nest" two days later and every speck of moss
was GONE! Twenty feet away there was a new nest with one tufted titmouse egg in
the second box.....They can move to a better location even when they are about
to lay an egg.
Pine needles... Where short leaf pine needles are available very often these
soft short needles are used exclusively for building a nest....Bluebirds do not
fly very far to collect their nesting material if they can find soft grass that
was mowed and dried in your yard the entire box may be "Bermuda grass" even if
you have pine trees in your yard.... You can rake pine needles up out of your
territory and bring them into your yard scatter them around and run the lawn
mower over them and see if they use them....I have found entire bluebird nests
built out of only the pollen tassels from oak trees.....They use and build nests
out of whatever is available....Enjoy these birds because you will see things NO

Jim, et al,
I answered you once, but for some reason I guess it didn't get through. I'll try
again.
Based on what I've read on the subject, and on my own experience, I would say
that Bluebirds do not "mate for life" in the sense that birds like geese and
swans do.
For one reason, small birds like Bluebirds are getting picked off pretty
regularly by various kinds of predators, so an individual's life is often quite
short.
They just don't live long enough, on average, to enjoy a lengthy mated life.
Also, when mating season starts in the spring, there always seems to be a lot
of pre-mating competition going on. The males are trying to convince the females
of their virility, their competence, their skill at finding good cavities, their
ability to provide food, and for all we know, their handsomeness and their fine
singing voices.
If a Bluebird loses a mate somehow during the mating season, he/she often
finds another one. Also, we read often about apparent bigamy among them.
I hope that the real scientists will chime in here if I've misspoken myself.

I am far from a scientist but I do know that recent research has shown that,
even for birds like geese and swans that were always felt to be mated for life,
that life link lasts only as long as both of the pair are alive. It has now been
shown that the widow or widower will remate the following season in many cases.
I agree with Bruce on the concept of small birds, though. Paul Ehrlich in the
Birder's Handbook says, "most birds, however, are monogamous" although he
defines polygyny where one male mates with more than one female while each
female mates with only one male and polyandry where one female mates with more
than one male while each male mates with only one female.
Throw in a little philopatry (the tendency of previously mated adult birds to
return to their previous breeding territories) and your head will be spinning
with the Ps of pairings!

Bluebirds get most of their insects from the ground, so they like short or

easier. Thinking of having to peer down between blades of grass 4 or more feet

I just responded to Kate off-post and explained how I seldom see them feeding
on the ground along our bluebird trail. At the refuge here the nestboxes are in
fields and meadows surrounded by thousands of acres of Eastern forest (mixed
mid-Atlantic deciduous-pine). From my casual observations, it seems like most of
the time they fly directly from their nestboxes into shrubs, nearby trees or the
woods and return later with insects (caterpillars and other bugs). I know they
are getting ground-dwelling insects also because the remains of legs, wings, and
other parts are left in the nests. In this particular habitat, my guess is that
their major food source is found at the forest edge or just inside the forest.
I'm curious now to check out their ground-feeding behavior here a little closer.

rental property which keeps them on the defensive. I even supply these two with
mealies. In fact, I saw the male EABL dive bombing a red bellied woodpecker that
was on the mealie feeder today. There were 5 eggs which hatched last week
Tuesday and/or Wednesday. I did get to stick a mechanics mirror into into the
nestbox (slotted opening) for about 5-7 seconds before the the Blues were all

feathers. There very well could have been more than 3 nestlings.

When I first moved into a home in Reisterstown, Md, I saw some EABLs and
decided to erect a BB house. The male BB was the toughest damn little critter I
had seen in a while. One time he had a black bird on the ground dive bombing him
and then the female joined in. The black bird was laying there as if he were
dead. After awhile, the BBs tired out, I guess, and left him alone. When the
sustained attack was over, the black bird got up and flew like hell for safety.
Pardon my English.
I witnessed the same male BB wrestle to the ground a HOSP. It looked like the
BB version of the WWF. I was so proud of him until there were fledglings and
then he started to attack me whenever I would leave the house. He was a tough
cookie and I am sure if all BBs were like that one, we would probably be
protecting other bird species. : )
With him as the example, I was given the false impression that all male BBs
were the same. This is why I took no action when this year, I wasn’t worried
when I saw a HOSP competing for the house that I now have on my PA property. I
had the false notion that as soon as the male BB came around, the HOSP would
soon be in trouble. I guess I learned a very important lessen that all BBs are
born equal.

Subject: Is Mr. Blue a Lousy Husband?
I've been taking advantage of all the great advice posted on this list since
last summer, when I finally (four years after putting up a box) attracted my
first pair of bluebirds. I haven't had much time to read the list this year,
though, so please excuse me if my questions are repetitive.
I won't go into the long, incredible story of that first pair of birds, but I
have to say that the male seemed to be the perfect husband. He came to the box
frequently during the day to feed his mate as she kept the eggs warm...I never
saw her leave the box unless a human came too close.
Later in the summer, another pair took over the box. The new Mr. Blue almost
never fed his mate, but that was OK, it was very hot outside, and she could
leave often without a problem. For about a week , though, I never saw him and I
actually thought that he was dead or had abandoned her. Once the babies were
born he was like a differnt bird, and I think he worked harder to feed the
babies than Mrs. Blue. He also defended his territory aggressively.
I'm quite sure that its the same pair (the male at least) nesting in my box
this spring. Mr. Blue hardly ever feeds Mrs. Yesterday morning it was freezing,
and I did see him feed her once. Today I hadn't seen either of them for ages, so
I went outside and made some noises as I walked toward the box...Mrs. Blue peeks
out of the box when anyone comes close, and usually we don't get /too /close
because it has been chilly and we want her to stay on her eggs. Today I walked
right up to the box, and got no response. I tapped on the box...no response. I
opened the box, and there she was! Not a feather moved, and I thought she might
be dead, but I closed the box and got out of there. After about 20 minutes she
left the box, and I did see her reenter the box about 10 minutes later.
I thought she had starved to death! I could hardly believe that she would sit
motionless like that as I opened the box and looked at her. Is it common for the
male not to feed the female? Can she manage alone if the weather stays cold?
Last year it was easy to monitor the box because the females always flew out if
we came close. How can I monitor the box if Mrs Blue stays put?

Dear Judy, You have a very healthy and happy good Mrs Bluebird mom!
What she is doing is called, "sitting tight" - literally you could probably
lift her from the eggs and she wouldn't budge an inch. Obviously all is well in
your box. I wouldn't worry one iota about whether Mr is feeding her or not....
These birds are wizards at staying alive through hot, cold and cool weather. It
isn't until the weather is *exceedingly* cold or hot that you have a thing to
worry about!
All bluebirds have different personalities and it is good to trust that each
pair will be different than the next- but no problem - they know what to do - as
they've been doing it for a LONG long time....
When I have a EABL that "sits tight" I don't disturb her unless I absolutely
have to. If the box is located in your yard, you can watch for when she leaves
the box to go eat or to take a break and then you can go check the eggs.
I always say the same thing or sing the same tune before I come up to a box.
This way, the mom can come to know my sound and will often then leave the nest
when I approach. But some moms are just so darn tough, they'll "sit tight" no
matter what! What a miracle. :-) H

Looks to me like things are just fine. Relax and let them do their thing. I
think some feed their mates and others don't.

I went down to the trail this morning and in the afternoon and no sign of the
bluebird. Is it normal for a bluebird to hang around for a day leave and come
back some other time? Does anyone know what the typical behavior of males and
females are when they begin migrating? Does the male arrive first and go back to
find a female or does the female usually arrive with him? What should I expect?
I almost hope he didn't come back today, because a bunch of people were setting
off rockets and firecrackers in the field this afternoon. Uggggh! Something
tells me that's not a big attractant for bluebirds!
I wish you lots of luck! I lived here four years, never saw a

Our speaker for our meeting for next weekend in Baton Rouge came out and
filmed my trail. At one nestbox, (the one with 6 babies), both the female and
male dive-bombed me. I have never had the male to do that before. It was really
a sight with both of them coming at the same time! He got some wonderful footage
of that! This pair is very protective of their babies. Usually the male sits
right up above the nestbox on the power-line while she dive-bombs me. He got
some very good footage of them sitting on the wire. We took pictures of babies
from a few hours old to 10 days old, eggs and nests being built. We also took a
shot of the two nestboxes that we have to park some equipment between to block
the view so they will not see each other.
This is better than Christmas!

When "my" bluebirds act this protective, I try to monitor and get away as
quickly as possible--I'm trying to train them to be protective by making them
think their dive bombing works! :-))
