This is an addenda to Bruce Burdett's post about the tree swallows
leaving after nesting. Last year was my first successful year
with them, altho I'd been trying to attract them for a few years,
so I was REALLY excited when they nested & had babies...I
mean, it was like I was a new parent! I also have had terrible
bug problems with my horses, so I was hopeful that they could
help.
At one point I watched a pair building their nest take a feather
up into the air & let it float down while they dive bombed
it several times until it hit the ground, at which time they
started the process all over again. I was just totally awed.
As soon as their little babies fledged, which I was privileged
to watch & absolutely marvel over, the whole gang just disappeared....vanished!
I was despondent for days; at first I thought something was
wrong, but then I realized that it was something they did, but
I still can't fathom why.
Anybody have any ideas? I'm in lower Michigan, & they fledged
probably around the first of July, so there was plenty of heat,
& more than enough food, & the barn swallows across
the street hang around until September.

I don't know where they go, either, but I have a picture taken
last September, I think it was, of 40-50 tree swallows congregating
on the telephone wires near my house. We had fledged about 25
of them from nestboxes on our trail earlier in the year.

H-
Violet-Green Swallows (a close relative) also high-tail-it
shortly after they fledge at my "home box." And like
tree swallows, they arrive very early with most gone from my
"trail." by the middle of July. I think they find
a flock and hang out at least for a while before leaving the
area, as I can always find them post season at local ponds and
lakes.
Anyone out there with observations of VGSW vs. TRSW? I don't
think I have ever seen a TRSW nesting in downtown as I have
VGSW ("wild", that is unmonitored, ones, do have a
lot of trouble with HOSP, and are declining in urban areas).
Also, VGSW seem to be adapted to what I term crevice nesting,
not being dependent on tree holes. I've seen them nesting in
crevices of cliff faces in the Columbia River Gorge, chinks
caused by brick building demolition downtown, and my boxes have
2x7/8" slots not round holes. This is NOT to say that they
won't nest in tree holes and round hole nest boxes, but has
anyone seen *TRSW* in anything other than a round holed nest
box or tree hole?
Any insights into competition or limiting factors favoring
one or the other?

Horace,
Hello! Yes, she did put the leaf in the box. I did check it
yesterday & it is mostly grasses cuz I saw her take every
single piece to the box & saw where she was getting the
pieces for her nest. She got them from the old garden spot that
we let grow over w/ grasses then mowed over. Yesterday she just
had the floor covered w/ the materials. I haven't checked today.
Today I got up a little later than I wanted to, but did see
her take more material to the box 2 times. I was out there for
about an hour or so before the rain washed me out. Anyway, she
was defending her box from every single bird that would come
around it. Only 2 of the times a bird came to the box itself
a Finch & a Chickadee. The other birds that would come around
were either on the ground or just flying
past it. She stood her ground tho. Then some time later the
male finally arrived on the scene. & the female flew away
& he stood guard. It was so cute. I just checked the box
just a bit ago to see how it is holding up to the rainy weather...I
didn't open the box, but looked at the pieces of nest material
sticking out from the cracks underneath & it looks like
she has gotten some hickory nut stems, but not sure. I am going
to open the box a little later in the afternoon as I try to
open it when they aren't around about the same time in the afternoon.

Subject: Why Tree Swallows Leave
Greetings Birders of North America,
I don't know if anyone answered this as I did not see it on
the posted on the Listserve, so I will state what I read up
on. I read that once the young leave the nestbox, usually within
a day or two, the whole family will leave the area. They do
this to join up with their Tree Swallow buddies in swampy areas
where there is a abundance of flying insects. I also think,
if I recall correctly, that they may even join up with Purple
Martins at times. I am not sure on this and would have to check,
but it seems sensible.
Yesterday I counted 27 Tree Swallows in the air around the
house and divebombing each other and quarreling..............THE
USUAL. Though most of them won't nest here and move on to the
next trail.........wich could be miles and miles away.

I thought to share this with the list as it is neat. You see,
my Tree Swallow grid, which is a Swallow trail with boxes placed
30yds. apart in a square shape form. This grid is located in
a field, of which I don't own, just to the left of my home.
Today the man who owns it and his 32yr. old son came up to mow
the field. The son was the one who got the privelege to mow
the swallow packed field. I was sitting on the porch when almost
all the swallows came over and circled around the house. By
this time some of the swallows were already divebombing the
poor guy which was kinda funny looking as I don't think he has
ever seen such brasin birds! What the neat thing was, is the
swallows that were circling the house were getting in a "Formation"
kind of form! Seriously. Then they seemed to look at me for
"approval" I guess and just for the heck of it I said,
"Go get 'em boys!" and with that they headed right
for.............his head! I tell ya, when they started at him,
they looked like a formation of F-16s on a mission! One sight
I will NEVER forget.

Our tree swallows also dive-bomb people near their box. I have
actually felt them graze my hair. Fortunately, this wears off
a bit, since I can't avoid my yard altogether. They become less
aggressive when babies hatch, as they are then too busy finding
food for all those mouths. The swallows that have taken white
feathers from me during nest building generally do not dive-bomb
unless I have someone new (to them) with me. It could be worse
- we had baltimore orioles a few years ago, and we had to borrow
our daughter's toy hardhat to protect ourselves whenever we
ventured outside.

Tree swallows (TRES) arrived earlier this week and are exploring
boxes. I wanted to remind people that now is a good time in
the north to be gathering white feathers for them. If
you float feathers on a light breeze within sight of the box
(but not too close), you will get to witness close up the marvelous
acrobatics of these birds as they pick the feathers out of the
air. Often one will catch and then release a feather for
its mate, like a game of catch. This only works as the
nest is being built. Tiny soft feathers are stuffed into
the nest cup, and larger ones are usually inserted straight
up near the top, so the completed nest sometimes looks a bit like a Native American
head-dress. I use seagull feathers, no bigger than 4",
but have also used pale-colored chicken feathers when available.
Gull feathers are usually abundant along the lake shore or in
parking lots and school athletic fields where these birds congregate.
Feather chasing is really fun to watch, especially for children.

Hi All!
I do this, too, for my beloved Violet-Green Swallows(VGSW).
They are as acrobatic as the TRES. I read somewhere (probably
a report from Cornell) that feathers are not just an adornment,
but do provide for faster chick development and some protection
from external parasites). I wish I could remember where I saw
this information.
My feather source is a local park with scads of ducks and geese
(the feathers don't have to be white). The only problem is that
they start the molt in June and the VGSW are finished collecting
feathers (they stop when the eggs are laid) by then. So I have
to collect for the next season. Personally, I like the larger
breast and tertial feathers (2-5"), but the swallows love
anything, except down. So I have what I call "fishing feathers"
(the little 1" feathers) to see if anyone's interested
before tossing out the "good" ones.

In general, boxes for tree swallows should face open fields

seem to prefer the one that faces south.

checking out our 2nd bluebird house (it's paired 10-15 feet

the trees are bothered by traffic.
Our houses are about 10-12 feet up on a hill and about 10-12
feet from a two-lane paved road that is fairly busy during the
day. Both houses face east (which is away from the wind and
the road is behind the houses), but I read someone else's email
regarding tree swallows saying the house should face south and
away from traffic.
Do you think that the traffic will bother the tree swallows,
should I turn the house to face south, and what can I do to
"attract" the trees so they pick my house? ...

Last year was the first year I ever had a 2nd nesting of tree

producing 24 babies (eggs: 8 & 7 in first nesting; 4 &
5 in second). I knew TRES nest twice in southern areas, but
had never heard of them nesting twice in the north.
This year, in one set-up of tripled boxes - each in a line
of about 10' or so between the boxes - all three boxes are occupied
by tree swallows - with almost no bickering among them. Wish
the blues would be willing to nest so closely to each other.

them spends a lot of time in the box. Several times I have seen
him/her take a beak full of grass into the box. Another pair
keeps checking out a thire box about 25 feet away. Again spending
lots of time looking in and only a few blades of grass in this
one. What is there breeding and nesting schedule? How many eggs

I can only add a tiny bit of info, Paul. I started my first

When I opened the box to clean it, it was FULL of mites. So,

to fledge even though they have a box full of mites. Sorry I
can't add more. VMS
I didn't find mites on bluebirds but found a bald headed TRES..
At first I thought it was pecked by HOSP.. Now actually this
story is a bit amusing.. Somebody was teaching a high school
student about monitoring. They were on the trail and I tagged
along. The student saw the bird in the box.. all of them empty
so far or had HOSP nests.. She panicked and was joined in by
the mentor who SCREAMED!! I'm standing there thinking.. "Oh
so there's a bird in there and well yeah maybe it's dead"
Well I go and look now after the SCREAMING HA HA... Anyway it's
alive and it's a TRES but a bald one at that.. So there's no
blood the bird flew off my hand when I released it.. Must be
mites.. but I'm still learning too I never say never and never
say always.. I got TRES using gum wrappers this year turned
silver side down.. can't find feathers I guess. and about 2
years ago I remember telling about the one using paper towels.
Listened to the pairing debate as well.. I have TRES in boxes

Subject: Avian Air Traffic Controllers
The only thing that will be anthropomorphic about this post
is the subject line!
I am fascinated by the behavior of the Tree Swallows (TRES)
that I have been observing ( from a distance ) in my yard. I
have not had the opportunity before to observe TRES so closely
( from a distance - sitting on my deck ). There are two boxes
paired in the front lawn. Eastern Bluebirds (EABL) are incubating
five eggs in one and a pair of TRES have chosen the other. For
about two weeks the TRES have been around every day, sometimes
just flying around, often going in and out of the box, very
often one of them stays in the box for a long time with its
head poking out just looking. Last year I observed ( elsewhere
- not in my yard ) them doing this during incubation but this
year they were doing it lots before they even started a nest.
Finally a few days ago I observed them starting to build a bit.
I know they often take a long time to build their nests.
But the really interesting thing I have been observing is the
way they protect the box AND the "air space" above
it. I have read that they protect the immediate area around
the box and this seems to be the case. They and the EABL quickly
sorted themselves out without very much ado around the boxes.
But what is really interesting and admirable I think is the
way the TRES seem to be controlling the bowl of sky above. If
anything that could be considered threatening crosses this "air
space" the TRES appear ( even if they did not seem to be
in the area they appear as if from nowhere) and see the intruder
off. So far they have re-directed other TRES (many times), crows
(several times), Bluejays (a few times) Red-tailed hawks (twice),
and last night a large seagull ( not sure what kind - it was
quite high up ). This is just while I've been watching. Nothing
even gets low down enough to GET near the box. I admire their
devotion and tenacity to a box that doesn't even have much in
it yet ( I checked yesterday - only time in the two weeks they've
been here ) and there is just the smallest start of a nest.
It seems to me that they are protecting a much wider area around
the box than the books say but that they act ( I won't say think
) on a different plane from us. They are protecting UPWARDS
( very high upwards ) which seems to me eminently sensible for
a bird! Now I know I will probably get some expert writing to
say that this is not what they are doing ( but if so please
say what they ARE doing then ), or others who will say this
is old hat to them and they've seen it many times from TRES.
* Is* it common or do I have an unusually defensive pair? Whatever
- I, in my innocence, am finding it interesting and plan to
keep records of how many species they control through their
chosen "air space".

Subject: Re: tree swallows & bluebirds
Good day folks,
I just wanted to let you know the bluebird box now contains
5 blue eggs! But I have a couple of questions.
This morning the mother bluebird from inside the box kept tree
swallows from entering. Tree swallows stayed in the area so....
and I don't know if the timing is all off and I should have
just watched from the sidelines .... I put up another box 15'
away as suggested hoping that the two birds can coexist. I watched
all morning. The bluebird (male) is not crazy about having tree
swallows move in and flies at the tree swallows whenever they
try to enter the new box. It's not likely is it that by trying
to fix a problem (by putting up a new box nearby ) I created
one (the bluebirds leave their nest/eggs behind & move elsewhere)?
Another question came up this morning when I discovered the
base nest of a house wren in a box set up in trees in the back
yard. I also saw the wren up close. The bluebird & now tree
swallow boxes are in the open in a field about three-four hundred
feet way. Should one discourage house wrens from taking up residence
ie. pull the twigs out of the box knowing they can be so destructive
to other birds' eggs.
Thank you for any of your own experiences, insights, advice.

Hi Joe and all, Some people have the belief that if you already
have Bluebirds don't encourage Tree Swallows. This idea was
created by Tree swallows taking all boxes provided. Pairing
was thought of and proved to be a way to also have Bluebirds
since two pair of Swallows don't favor nesting within 15 ft.
of another Tree Swallow. In areas heavily populated with Tree
Swallows pair boxes so you can get one with Bluebirds. In your
case there is no need to put up the second box unless you want
to get Tree Swallows. By my way of thinking putting up another
box will not hurt anything. The bickering between Bluebirds
and Swallows will taper off as both finally settle in. They
don't physically hurt each other in their battles. Your choice.

For the first time, I have had a tree swallow in my yard. Over

sitting in it looking out, sitting on top of it. So far, however,
the box is empty. Since I have no close experience with TRES,
I don't know how to interpret this behavior.
Questions:
1) How late do TRES nest in New England? Do they have more than

Hi Katherine,
TRES are JUST now nesting in MA. I have one box of 17 that
is actually incubating. A few have just a few eggs and most
have none at all. TRES are really unpredictable. Just as they
fly foot loose and fancy free, so is their nesting behavior.
One nest might be almost all feathers, the next mostly nesting
grasses. One pair like chicken feathers, the next blue jay feathers.
Sometimes they'll start a nest immediately upon claiming a box,
sometimes it seems to take weeks! They are lots of fun to keep
track of.
I bet they'll start a nest soon. Make sure there are no wasps
in the box. Watch for "claim straws".
They have one clutch a year unless their first attempt fails.
TRES do not eat mealworms. They eat bugs from the air.
Keep us posted! :-)

Subject: TRES - Thanks, Update and Question
Thanks to everyone who gave me valuable info about tree swallows.
As for the update, there's not much news.
These guys have been loitering around my yard on and off for
days. Usually I see only two, but the other day I saw four and
it looked as though there were some sort of territorial squabble
going on - either that or a lively game of tag.
A few days ago (May 14), I actually saw a pair copulating on
a high branch. However, according to Stokes, TRES start laying
eggs about a week after mating, and nest-building takes from
two to four weeks.... so if these guys don't have even the beginnings
of a nest yet, they're going to be laying eggs on the floor!
:-)
Somebody (was that you, Shelly?) pointed out that this may
be a different pair, and they may already have a nest somewhere
(I hope so, for their sake) and that it may be another pair
that's inspecting the box.
Yesterday and the day before it was rainy, and I was sick,
so I didn't get out much, but today, once again, I saw them
inspecting the same nest box as before (this box, for those
who asked, is "paired" with the Gilbertson box the
chickadees are in), but there are still no nesting materials
in it. There are a few wood chips that I had put in at the beginning
of the season, and a little "cluster" of pine needles
(just three needles joined together at one end) which I hesitate
to think of as a "claim straw", but who knows?
Question:
Those of you who know tree swallows: do you think I should put
some grass in the box to encourage them? Or will that make them
think the box has been taken by somebody else? Has anyone ever
tried this? Should I take some feathers out of a pillow and
put them near the box? I'm happy to have them here on any terms.

I dashed over and checked. Tree swallows with four eggs in one

I closed up the tree swallow nestbox, telling the divebombing
mama TRES that she was most welcome, punctured the sparrow eggs,
and returned to watching what I hoped would be a fledging. No

I've heard that spreading feathers about is responded to positively

Thanks, Dot, I will immediately go out there and remove anything
that's in the box (unless they've started a nest). The wood
chips are really down to a minimum - they don't even cover the floor. But I will make it
squeaky clean. (Wouldn't a natural cavity have some kind of
plant debris in it?)
In fact just today, more than once, I have seen both male and
female leaving the box, one after the other, the undeniable
implication being that they were in there together. What *could* they have been doing? Is it
possible that they are just using the box as a rest stop?
I have read (Stokes) that there is great variation in TRES
nest-building behavior, so as long as they are around, I will

I opened a TRES box up the other day and there were two TRES
in there - one on top of the other. I'll let you come to the
final conclusion of what they were doing in there!!!!!!
I never heard the clean the box out so carefully - but I do
agree with the Stokes that they are VERY unpredictable when
it comes to nest building, timing, etc. They break all the rules
- better yet, they just don't seem to have many rules!!
I almost think each TRES nest is like a snowflake - there are
never two a like. One will build a big nest, another practically
no nest at all, another with no feathers, another with jay feathers,
another with chix feathers - you name it! Some with trash, etc.
I found a TRES nest the other day with a small store receipt
laying right on teh bottom of the nest - I could see all the
numbers, etc. As if they were reading it while sitting in the
nest! It fit the nest cup perfectly.

The part about the clean box is weird. On rural trails, it
was not unusual to find TRES nesting on top of old nest materials.
In my neighborhood, however, they seem to have a fit if anything
is already in the box, flying around with alarmed noises and
looking in the hole but refusing to enter. They often sit on
the TV antenna and wait for me to clean it out. My very first
pair of backyard bluebirds did a similar thing - there was a
partial swallow nest with male watching (female had been killed)
- and the bluebird pair acted as though they expected me to
clean out the box instantly (which I did). Two TRES together
inside also seems to be common. They will dash in at full speed,
one right after the other, and chatter noisily, but I don't
think there's enough room inside for mating. They much prefer
my TV antenna for that. Haleya's right about the nest, too.
Our first TRES backyard nest was so big that the top feathers
were bent under the roof, and the next one was so small that
you could see bare wood through the bottom. TRES are also prone
to rapidly building a nest and then completely disappearing
for a few days before continuing the nesting cycle. They are
oddballs for sure, but fun to have.

Another way to limit TRES nesting - at least here in western
MA - is to get all boxes up EARLY, before the TRES arrive. That
way EABL have first pick of boxes and they'll take most of the
boxes. Once the TRES return, avoid (if you can) putting up new
boxes until well after they've started to nest - unless you
put up paired boxes. Now this is especially true for folks with
trails. Obviously for those who have one or two boxes don't
stop yourself from putting
up a box at any time! I find if I follow this protocol, I can
limit the numbers of TRES nesting. I am not looking to eliminate
TRES from nesting - simply to limit... When I don't follow this
protocol I find the second I put up a box I've got TRES ready
to grab it. In that case, I pair the box so that EABL can come
at their own leisure without being pestered away by the TRES.

While not practical for every "backyard" bluebirder,
I found some notes from Don Wilkins in Park Rapids Minn. saying that he felt he
could reduce house wrens by avoiding deciduous woods and place his trail
boxes in or near conifer woods. For some reason this severely limited the numbers
of house wrens as evidently their main food source relied on a hardwood
mixture of trees. He also limited the numbers of tree swallows by placing
his "bluebird" boxes in small clearings where the swallows
had limited maneuverability getting to or away from the boxes. He placed
"tree swallow"
boxes near streams and lakes and marsh areas and was very proud
of the fact that he could attract many different species and PREDICT which
species just by careful selection of the nest site. Few backyard birders
have this luxury. While Don limited his bluebird sites to specific habitat
he also was the leading producer of bluebirds for several years in Minnesota
where there are a LOT of good bluebird trails!
I would like to see every backyard birder with only a couple
of nestboxes mount their box to a telescoping pole so that the box could
be easily raised and lowered up to the 7 or 8 foot cat resistant height. I would
like to see each pole fitted with the Ron Kingston type 8" stovepipe
guard to reduce the possibilities of climbing predators and place a dab of grease
up under the stovepipe so that you can see if snakes are trying to reach
the nest and also to stop ants and climbing insects. A 1&1/2" round
entrance hole in the east and a 1&9/16" round hole in the west and we have eliminated starlings from entering the box.
There are still a few predators that we cannot stop with this
set up but you have done ALL that is passively possible! There is no need
to worry too much about the loss of eggs or even young as these birds will
renest as often as it takes until they raise some young. Bluebirds can
lose 15 eggs in a season and still raise enough young to continue their family
line of descendents. Give the birds plenty of choices in nest sites
and lots of empty boxes and you WILL increase the numbers of birds fledged
and ANY native bird fledging young in one of your boxes should be considered
a
miracle! Take the time to cherish it!
In 1979 I "deleted" very few adult house sparrows
and actually lost very few native birds to them in areas high in concentration with
the sparrows. The strong do learn how to coexist or at least survive and this
is what our goal should be! We should be helping the smartest and strongest
individuals of the native species to stick around into the next century
and not worry about the jays, hawks, crows and other "predators" that we see near our birds!
There are over a billion domestic chickens in the US that were genetically selected for fast growth. They have lost all ability
to find natural food and water for themselves or even to raise their
own young. This has happened in less than 50 years. Losses to us seem cruel
but it teaches the adults to be better parents the next nesting or at least
to choose a better mate! KK

Haleya,your comment about avoiding TRES by getting the boxes
up early jolted my short term memory a bit. I had apair of EABLs
checking out a box the first part of Feb.-- not every day, but
more frequently as time wore on,entering the box and the whole
nine yards,like they owned it.But when the TRES returned--they
took over thebox the first day.No argument, it was their box,
period.And the EABLs took another box about 20ft. away.Funny
part was that it was weeks before the TRES even started to build
a nest.But they both have thier progeny started---the EABLs
have hatched and the TRES with the usual 6 eggs.
Yes, I've had TRES take over a box when it was put up after
they returned --almost immediately after it was erected ! But
recently I've had sucess on single box sites by erecting another
box when I see EABLs in the area-- even if HOSP have claimed
the original box.I usually just move in an unproductive box

After the bluebirds arrived swallows came knocking and so a

It's raining here, today - finally! We really needed it, but
the birds are drenched.
The Tree Swallows, who have apparently decided to nest in the
box paired with the Gilbertson box that the chickadees are in
(see earlier posts) have not been seen today, and I'm not surprised.
Over the past few days they have brought a certain amount of
material to the box - mainly pine needles, dry grass, and little
stringy stuff from I don't know what tree - but the contents
of the box do not yet resemble a nest.
My questions: What do Tree Swallows do when it rains? Since
they are aerial foragers, do they starve if it rains for several
days consecutively (I know nestlings often die in this situation,
but what about the adults?)? Do they glean bugs off trees in
an emergency? And will they suspend nest building for days,
until the weather improves? At this rate there won't be any
eggs till July!!!

Dear Katherine,
You would think we'd loose a zillion TRES to this cold weather,

to literally disappear during weather like this. I do know they
often go near bodies of water and fly low to get bugs - where
the water temp is still higher than air temp.
The moms stay in the boxes an incubate. All those feathers
in the box keeps them toasty!
Like all birds, they can live a day or two or more on body
fat. When I worry about TRES in the cold, I remember just how
high their populations are and that reminds me that they are
doing SOMETHING right to keep themselves ok through the cold
weather!!! :-) Last year was nasty cold and many of us were
especially worried about the TRES. But no one reported terrible
losses of the TRES poplulations.
Those little birds (I still think they are bats with cloaks)
are tough and I wouldn't worry about them one bit!!! They may
seem flighty and unpredictable, but I think they are much smarter

Tree Swallows start incubation with the next to last (penultimate)
egg. Hatch occurs 13-14 days later. Fledging occurs 16-30 days
after hatch. Beware that Tree Swallows are sensitive to weather;
they will interrupt laying and/or delay incubation if weather

Hi Cinda, and all other novice tree swallow "guardians",
Tree swallows (TRES) do not tolerate interference as much as
bluebirds do. They will not abandon if you look, but they will
become upset and divebomb you. If you have never seen
their nesting cycle, naturally you are curious. Probably
the safest time to look at babies is a few days after eggs have
hatched and the female no longer stays in the box with them
all the time. I personally am a firm believer in leaving
our wild visitors alone as much as possible. I do not
interfere with my TRES unless there is an obvious problem
such as parents refusing to enter the box or flying round and
round making alarmed calls. I see no need whatsoever (under
normal circumstances) to be handling the eggs or young of any
bird species.
*IMPORTANT* Boxes for tree swallows should be rough on
the inside front under the entrance hole. TRES toes were
not made for climbing, and standard bluebird boxes are often
too deep for their shallow nests. Parents do not return to the
box to feed the young inside once the first one has fledged.
All too often, the first two babies fledge by standing
on top of the others, but the rest can not climb out, and starve
to death. I learned this lesson from bitter experience, and
can assure you that there's nothing much worse than watching
over a month's work by TRES ending with 3-4 healthy dead babies
who simply could not climb up to the hole to get out. If
you make your own boxes, use rough-cut lumber for the inside
front. If your purchased box is new and/or smooth
inside, it would be wise to risk the swallow's wrath and quickly
open the box to score or gouge out the inside front to provide
toeholds - a tool such as an old screwdriver will do the job
in a hurry. If you've looked at the Antietam nestbox camera,
you can see the scored lines running horizontally across the
inside front under the hole.

With all due respect to Dot, I disagree with the statement
she wrote below:
Tree swallows (TRES) do not tolerate interference as much as
bluebirds do.
I quote a well-known Tree Swallow expert, researcher, and professor
at Cornell, "It would take a sledge hammer to make a tree
swallow abandon a nest."
Yes, it's true they will divebomb you. They will also squawk
and scold you and they'll look fierce. They are defending their
territory and their nest. But, they will not harm you and they
will not abandon.
Want to peek in during the egg laying period to see how many
eggs there are? Go ahead. It's not a problem. Want to peek in
after incubation has started? Go ahead. You may see the female
on the nest looking right back at you or hiding in the feathers.
You can also peek in after the eggs have hatched.
While roughing up the inside below the hole for the chicks
is accepted procedure, I, however, am not so sure it's entirely
necessary. I band tree swallows (both adults and chicks) and
part of the method is to have the bird grip my finger. I can
attest that tree swallows do have a strong grip. I would appreciate
someone telling me if there was a study done regarding the ability
of tree swallow chicks to climb various surfaces to the hole.
I wish I knew why many of our procedures became accepted and,
therefore, gospel. Another one I question is the required dry
nest. Remember the bluebird nest in the top of a fence post
last year? That must have gotten wet when it rained, but they
fledged. The nestbox itself dries quickly; wouldn't that wick
the water away from the nest? And nest replacement because of
blowfly infestation. Terry Whitworth has previously stated that
chicks were little "blood-producing machines" and
he felt nest replacement due to blowfly larvae was normally
unnecessary.
I'm tired. Can you tell? I'm off the soapbox now and prepared
for your angry responses.

I am happy to report that the pair of TREe Swallows I wrote
about earlier has begun laying eggs in the nestbox on my lawn.
Today at around 5:00, when I saw the female leave, I looked
in and found two white eggs. This would seem to indicate that
the first egg was laid yesterday. I have read that they can
interrupt egg-laying and even incubating, but I know there were
no eggs three days ago.
There were a few feathers in the nest, but not many; I think
the TRES may have difficulty finding soft white feathers around
here, so the other day I took a few from one of my pillows and
placed them near the box. Meanwhile it rained, and the feathers
got wet. I have no idea whether they are using the ones I offered,
or if they were successful in finding others on their own.
This female is brown - a lovely taupe color, actually, so I
think she must be in her first breeding year. I hope her first
nesting experience is a successful one. I have seen both the
male and female looking out of the nest; I know the male doesn't
brood; is it common for him to spend time in the nestbox after
eggs are laid?
Questions:
How much monitoring will TRES tolerate? I have been looking
in fairly regularly, when I see the adults are not in the box
(on the order of once a day), because TRES are a new experience
for me and I'm anxious to learn all I can about them. I also
want to know the number of eggs in the clutch (for TBN). Once
incubation starts, I will decrease the frequency with which
I look.
The box they are using does not have a predator guard. (I didn't
put one up originally because I didn't think the box was being
used.) I would like to put a stovepipe baffle on it. This would
entail taking the box down for about 3 minutes while I mount
the baffle. Do you think it's too late to do this? I would hate
to have them abandon their nest and eggs.

I meant only that tree swallows are more aggressive toward

get an egg count for TRES and check every few days to see that
chicks are all OK. I was trying to make the point that too much
interference in the life cycle of wild birds is not such a good
thing, and that there is no need to be handling eggs and chicks
under normal circumstances. The majority of people on this list,

I have a lot of TRES. Actually, I like them better than most
of the other box users. They're incredible "sticky",
refusing to give up the nest even when I lift her up with a
finger in order to count the eggs under her...
I usually try to catch each female once during the nesting
cycle so that I can check her for bands, injury, and so on...
I've taken 'em out, looked 'em over, and put 'em back, and all
she did was snuggle down over the eggs and pretend that she
didn't see me...(:-)!
I don't know about the roughing up the box part. The ones I
monitor aren't like that. On Saturday I made the mistake of
opening a box I shouldn't have (it was on the verge of fledging).
I got off by one column in my chart, and opened a box with ready-to-fledge
young. As soon as I did that, they started thrashing around,
and instead of getting to grab what I thought was a brooding
female on 10 day eggs, I got a 23 day old hatchling!
I put it back, without examining it, and quickly and carefully
closed the box. I held the hole closed and tried to listen to
make sure I didn't snag somebody with the door. Things quieted
down, so I removed my hand from the hole and stepped back. Then,
as we stood 2 - 3 feet from the box, each one jumped up, looked
out of the hole at me, and in 10 second intervals--took off!
I was absolutely mortified that I'd caused an early and probably
unplanned fledging. But as each one jumped out, it was so incredibly
gratifying to see them flutter and struggle as they approached
the ground, and then clearly get a handle on what it was all
about and begin to fly and climb. Each one flew to the same
pine tree about 80 meters from the box. Each one, after a rocky
start, seemed to catch on, and flew in that peculiar zig-zag
pattern looking much like an adult... It was clear that they
were doing just fine! As we came back through that area on the
return trip, we could see them flying after the parents getting
fed in flight...SO NEAT!

Hi Katherine and congrats on your TRES eggs! It is not too

is so much easier to build and handle!! Same idea as a stove
pipe, but less work and less chance of injury handling cut stove
pipe. I can make PVC baffles (I am in the middle of making one
dozen now) in about 10-15 minutes. In terms of the
feathers in the nest: I believe TRES nests are like snow flakes.
You'll never find two identical!! On one of my golf course sites

feathers - and one no feathers at all!!! But you can see if
your TRES want your down feathers. A good experiment.
Egg-laying: Yes, TRES are terribly unpredictable. She might
lay one a day, and may lay one and skip a day or two or even
a few! Or she could lay every day like clockwork.
Avoid monitoring ANY bird's nest between 7 am and 10:00am if
you know they are in a laying stage. This is when they lay and
you sure wouldn't want to disturb her during that time!
Frequency of Monitoring: I believe in frequent monitoring and
I find that TRES don't mind being monitored as long as you are
very courteous. Many feel this as "excessive" but
I stop a lot of trouble before it starts this way. But not absolutely
necessary. You'll find your own rhythm. TRES nests are a bear
to monitor because if it has a lot of feathers you won't know
what is a feather, what is a baby, what is a mom, and what monsters
await you under all those feathers!!! I have a 4'
tomato stake set up about 4' from my backyard TRES nest. Happened
to be there from my garden and I didn't move it when I set the
box. Well, the male perches on that pole endlessly. I recommend
this as he can protect the nest better this way.
Hope this answers some of your questions! :-) Keep us posted!

Are you sure they were incubating to start with?????? She might
be still laying, in which case they would be cold until she
finished laying. They might be off having a break. I doubt they'd
abandon ship just for that reason. Of course it is possible,
but don't panic and pull the eggs until you know for sure!
I was over at a friend's house tonight. She had two nests of
eggs and babies gobbled up by snakes. Both nests are in process
of relaying. We took the entire TRES nest down, pulled out the
nest with eggs to get the old box off the post. We re-attached
the box to a electric conduit, put on a PVC baffle and put the
box back up and the nest back in. I never worried parents wouldn't
return. Took a good 10 minutes.

Hi Brenda and all,
My very first back yard tree swallow nesting came about 10
years ago, in a brand-new box. Before then, on my trail, I only
got to check the TRES every few days. Those boxes were well-weathered
with no smooth surfaces. Since this close-up view of activities
was new to me and the box could be easily seen from the garage
back window, I watched constantly when fledging was due. I had
seen 6 healthy chicks when I checked this box 4 days earlier.
I saw the first two TRES fledge, and saw the next one peering
out the hole. We had to leave for the weekend an hour later.
When we returned, I checked the box expecting to find it empty.
Instead I found 4 dead chicks who were fully developed with
no signs of injury or illness. I know for sure that at least
one of them, the one I saw at the hole before we left, was not
sick. The only reasonable assumption I could make is that he
and the other three could not climb out. I can think of no other
explanation. Since then, as a precaution, I rough up the inside
front of all my boxes, and have not seen trapped TRES chicks
since. All any of us can do is report our personal experiences
in hopes that others will avoid similar disasters.

There is no harm in roughing up the inside. But please consider
this: Is there a chance the TRES chicks died for some reason a day or
two before fledging , but you're attributing it to the inability to climb
to the hole? I've found one or two dead chicks remaining after others have
fledged in boxes made from rough-cut lumber. Those chicks died due to some
other reason that we'll probably never know.

Hi Dot & All:
Thanks for your report on fledglings unable to exit box. You
are so right to rough up the front of the box below the entrance
hole.
Often, just after migration from Central & S. America adult
Tree Swallows can be found dead in box. The legs of the Tree
Swallow are not as strong as other songbirds and upon arriving
from their migration they are exhausted & have difficulty
exiting the box after resting. It is therefore important that
the wood or plastic allows for easy foothold.

Katherine, et al,
Partly because ALL my 60 houses are 1 to 10 miles from my yard,
I don't monitor any of them more often than every week or 10
days. I can't prove scientifically that this regimen is good
for the birds or bad, but most of the nestings out there are
successful, including the Tree Swallows'. I think
I have about 23 Tree Swallow nestings in progress right now
at my 30 'sites'. As you're probably all tired of hearing, all
my houses are paired - 15' apart - and normally about 27 of
the 30 'sites' have one Tree Swallow nesting. In 6 years of
pairing I've never had BOTH houses taken by EITHER Tree Swallows
or Bluebirds. A majority of my 'sites' have both species simultaneously.
In no case have both houses remained empty. If you enjoy providing
white stuff for the Tree Swallows, try a few shreds of dry kleenex.
Mine seem to like it as much as feathers. But I must emphasize
that I put it out simply to amuse myself. I doubt very much
that the swallows "need" it. I hope I've helped with
your questions, Katherine. A word of caution, - especially to
newbies: Don't let yourself be put off by the small handful
of Listers who tend to use pretty harsh words. At my age, I've
learned to take their outbursts with a grain or two of salt.
And I've also learned never to reply in kind.

Kate, et al,
I, too, have often picked up the female Tree Swallow from the
nest, counted or inspected whatever was under her, checked her
for bands, and replaced her gently. She usually settles right
down and seems un-fazed by the experience. More
important, I think, is that we do whatever we do deftly, quietly,
gently, and quickly, and that we get the box closed up again
in as few seconds as possible, especially when the weather is
chilly and/or windy. In response to the lady who
thinks the eggs are "cold," I agree with the person
who suggested that perhaps she (the female, not the lady) had
not finished laying the whole clutch, and had not started setting
yet. Most females here lay 7 or 8 eggs before they're through,
and they don't start setting until the last egg of the string
is laid. I'll have to add that I have never been
able to detect whether eggs are cold or not. Some of you must
have more temperature-sensitive hands than I have. Maybe I just
have too many calluses. I always make 6 or 8 saw kerfs inside
under the hole, similar to the ones I cut on the outside on
the entrance-block. These kerfs seem to provide sufficient claw-holds
for everybody who might need them, inside or out.
Almost all of my defunct Tree Swallows are in empty boxes, and
I attribute these losses to the old Long-Exhausting-Trip-and-Stubby-Leg
Theory. (LETSLT) Just possibly, Survival of the Fittest, plus
Natural Selection, are both going on. In a honey-bee hive, many
thousands of worker bees, every summer, die routinely of sheer
exhaustion and raggedy wings. Bruce Burdett, SW NH

The information from Cornell states "Incubation begins

Subject: Re: Tree Swallow Incubation Initiation
I was wondering about that, too. I have lots more tree swallows
(TRES) here than bluebirds, and always count eggs before and
after incubation starts. Most of my TRES over the years have
laid 7 eggs, often six, and seldom 8. First-year females (not
yet turquoise in color) tend to lay one less egg than the above.
There was no way to tell when incubation began on my trail,
but once I had boxes in my yard, I kept track of that (10 years
now and 16 total nestings). I found that incubation was begun
in 12 boxes after the last egg was laid. The other 4 began incubation
began with the next-to-last egg. I have no idea what this means
- just passing on my personal report. Perhaps it's weather-related,
but unfortunately I didn't keep track of weather conditions.

Hello Theresa, Kate and all. I usually collect the feathers
that our Umbrella Cockatoo sheds and take them to the park.
I throw them to the wind, and one or both TRES sweep down and
catch them, often before they hit the ground... Even though
there are geese and other feather sources in the park, the TRES
like an easy feather if they can get it... They are fun to watch.

Katherine... I am soo sorry. Is the TRES still laying or was
she incubating?? If she was still laying you might be in luck
and also check the nest again just to make sure she didn't find
an egg somewhere in a corner that the wren moved to the side
somehow and missed. The problem is that if she is still laying
and lays more you are going to wind up with the same problem.
If she lays another egg tomorrow I'd move that box a good 20ft
every day until you can get her as far away from the wren nest
as possible. I don't know if it is wise to move
the wren box, perhaps others can give their thoughts on that
- as that may be illegal! After this nesting of wrens, you'll
need to rethink putting up boxes for your wrens. They are native,
so are protected by law, but they sure can wreak havoc as you
are finding out. I've lost nests to wrens before - and it is
a matter of out smarting them by moving boxes far enough away
from where they nest, etc.

She is laying. So, as others have pointed out, she may well
have to continue. I hope she and her mate will be more vigilant
now.

Unfortunately, there is no place to move it.. the wren box
is already way on the other side of the property - on the other
side of the driveway, in fact. Anywhere I move it would be closer
to the tree line, which is already too close for comfort. The
only direction I could move it away from the trees would be
right next to the chickadee box, and I'm not sure how either
family would like that. Of course the 'dees should fledge in
a few days, so maybe they don't care.. (But then that box will
be empty, and the wrens may move into it, so that doesn't look
like such a good idea either).
I don't know if it is wise to move the wren box, perhaps others
can give their thoughts on that - as that may be illegal!
I wouldn't dream of moving the wren box - as I said, it's all
the way across the property anyway, as far as it can be from
the TRES box.

up boxes for your wrens. They are native, so are protected by law, but

Yes, and in fact, the box the wrens are using is not a wren
box. One reason I put up two more boxes this year was to give
the wrens lots of choices, in the hope that they would leave
the other birds alone. This was suggested by a discussion on
"nestbox saturation" on BB-L last year. At present
there are three vacant boxes - the HOWR would be welcome to
any one of those.
All the boxes except one are meant for bluebirds, except for
the ones on the trees, which have in the past been successfully
used by titmice (but are not being used this year). All in all,
I have six boxes mounted, basically divided into three pairs:
two on trees at the edge of the woods, two on the lawn (BCCH
and TRES) and two on the other side of the yard, of which one
(HOWR) is a Springer chalet and the other is a hanging wren/dee
box. Last year, the dees used the hanging box and successfully
repelled a HOWR who tried to take it over. This year they moved
to the Gilbertson on the other side of the driveway.
I've lost nests to wrens before - and it is a matter of out smarting them by moving boxes far enough away from where they
nest, etc.
That is possible if you have enough space. I really don't,
which is why I was surprised to have the TRES here in the first
place - I didn't think my yard was open enough. So, to sum up,
the only way I can really avoid this is to not put up boxes
at all. But then I would lose the dees and the titmice. Would
the birds be safer in the woods, or in other natural cavities?
The community garden not far from me (where both bluebirds and
TRES have nested) is rife with HOSP. At least (so far, anyway)
I don't have those.
Keep us posted and know that many of us have "been there
too"... :-)

Thanks again - we'll see what happens tomorrow. I wish I had
time to be out there constantly - I'd guard the nest for them
willingly.
