Subject: Eastern Bluebirds with feathers in nest!

OK Gang, Am I losing it, or what? We have a beautiful EABL pair building their nest in one of our nestboxes, and guess what....they are adding feathers!!!!! We have several ducks and geese on our front pond, which is near their nestbox, and they have been molting recently. I have been sitting and watching this box, "like a hawk" and watching every movement. I have seen no sparrows. The EABL couple are very diligent, making trips every couple of minutes adding nesting material. Mostly grass, but feathers, too! If I hadn't been watching this couple intently for the past 4 days, I would have suspected this to be a sparrow nest, just by looking at the nest! If anybody wants to see my pictures of this nest, just e-mail me and let me know!

I'm also taking pics. of the pair of EABL, but it is hard to get close enough to take good pictures. The zoom on the camera just doesn't zoom in enough. Please let me know your thoughts and experiences.

Respectfully,

The EABL incubating eggs here has feathers in it too. It's the first time that I have seen that.

No, you are not losing your mind. After seeing so many bluebirds around when I moved here, I went to a Bluebird Day sponsored by the Parks and Wildlife Service, read some books, and firmly believed that bluebirds make their nests only out of grass. (We know from this list that they also use pine straw.) The very first nestbox I put up was occupied very quickly, and the very first bluebird nest I ever observed was lined with the chestnut horse hair that I had placed nearby after doing some mane trimming. It made for a beautiful cup, and was probably softer than grass.

Bluebirds do not read the books, as I've said several times before. Observations like yours and many of the others on this list are adding to our store of knowledge.

It's nice to see that the "feather" fad is catching on in the eastern regions. Here on the west coast, a few of trend-setting nesters are into glitz . . . nestcups completely lined with cellophane.

One cutting-edge nester on my trail is a very discriminating collector . . . gathering only one specific type of ribbon over a period of weeks.
On my "Claimstraw" web page, you can view the photos showing the work of this western bluebird. First just one thin clear ribbon with black
dots. Weeks later, about a half dozen of these ribbons were carefully assembled on her nestbox floor before the nest straw was brought in. Today after work, I expected her nest to be finished. Almost. But this female *really* has a fettish for this one type of ribbon. She has now amassed these clear, thin dotted ribbons in the nestcup and is in the process of working them in.

You can view her work by going to my "Claimstraw" page and scrolling down to "Shappel"

It is really strange that there is no bottom on the nest cup.  I don't know where you
live, but is it possible to have a birder in your area come and look at your nests?  Did
you see bluebirds building them, or any other bird entering the box?  Here in my yard in
upstate NY, the cups are made of pine straw and tightly woven, with a bottom.  In fact,
the bottom is there before the sides of the cup are completely finished. The framework is
so tight that it would be very difficult to fit in any filling material.  I also have
never seen roots of any kind used.  Bluebird nests vary widely from region to region, but
I've not yet heard of one with no bottom.  I sure hope you get to see who is building this
nest.

It's even more strange, now.   I had to cut down a large tree near the bluebird boxes this weekend.   Before I did it, both the male and female bluebirds were at the nest off and on, with the female going all the way in and out and the male sticking his head in.        So, I delayed the tree felling for another hour.

But, then I had to get to work on the tree.   Since the chain saw scared the bluebirds away, I looked in each of the 2 (15 feet apart) bluebird boxes.

One box had been built up about 3 inches with tightly woven grass and very fine roots (mostly grass).  The other had been *identically* built up, but to a height of approximately 5 inches inside the box, again with grass and very fine roots (this is the hairy, very fine type of roots).  This second box (the oldest of the 2 but with the less-complete nest) also had 2 or 3 dark feathers stuck in the grass/fine roots structure, but other than those 2 or 3 feathers and an extra 2 inches in height, it was a carbon copy of the nest in the newer box.

Now to your questions.  **Both** nests had no bottom.  We can see the bottom of the box at the bottom of each nest (the box has a drain hole directly in the middle of the bottom and it is visible, along with about a 1 1/2 inch diameter clear area where there is no nest structure at all.   We are positive that the bluebirds have been working on the new (less complete) nest, since we have seen them going in and out of the box, but the other box is out of our sight until we are about 20 feet from it.

So, unless the bluebirds are just sightseeing at the nest box(es), they are the ones building the nest(s).  Or, alternatively, we have 2 pairs building one nest each.   Nevertheless, the nests are identical, no bottom and all, except for the 2 or 3 feathers in the older box, with the more complete nest.

It's a mystery to me, but I'm a novice.   We live in Maryland, near Baltimore and the weather has been, alternately, hot and cool and damp -- nothing consistent (today it is raining and cool and yesterday it was sunny and pleasant and the day before it was raining and cool).                                 VMS

I have seen "bottomless" nests as a second or third nesting attempt later in the season but not usually this early.  Is it possible these are young birds- maybe on their very first nesting attempt- that maybe don't quite have it "all together"?  Just keep watching and keep us informed!

    Bottomless nests: I hope I understand the thread completely - if so:  Many of my bluebirds build the bottom of the nest LAST. I often find the sides all done with no bottom of the nest - simply the bare bottom of the box. Unless they've abandoned ship (which is unlikely) you'll see the bottom built within a week or so. Early in the season - at least in the northern climes, the bluebirds are building and laying very erratically depending on the weather.  :-) H

Subject: I Need A Single Male Eastern Bluebird!

Hello All,

I witnessed an event Monday afternoon that I found interesting. I've got a small trail overlooking the Chesapeake Bay in MD. I currently have 3 active nests, a NABS style wooden box with 4 nestlings about 10 days old, a Gilbertson with 4 nestlings at 7 or 8 days and another Gilbertson with 5 eggs. About 40 yards from that last Gilbertson I have another NABS wooden box which seems to do a good job of distracting the House Sparrows away from the Bluebirds until I can get them. Just minutes after I had removed the 3rd pair of them from that box this spring and cleaned it out, a male Bluebird was investigating it and hunting for bugs underneath it, a female that I assumed was his mate was sitting on the closest fencepost to him just about 6 feet away. This is a typical barbed wire fence surrounding a cow pasture. I didn't notice which way either had come from. He grabbed a big juicy catapiller and went to the next fencepost over from the female while he beat it up a little (tenderizing it). Well, the female started wing-waving at him, I've seen the male do this while trying to lure a female during courtship rituals but I didn't realize it went both ways. It seemed she was hoping to get the catapiller as an courtship offering like I've heard the male will do. She was very forward, she even hopped across the barbed wire to get within a couple of feet of him while still waving. A couple of seconds after that he took off with the morsel in the opposite direction, flying straight to the Gilbertson, and gave the catapiller to his
real mate who was incubating the 5 eggs! So it appears I have a lonely female hungry for some male attention, does anyone have a lonely stud I can fix her up with? Haha. Is there any chance this one male will try to keep both females happy?

Subject: MOBL Hybrid Female?

Haleya Priest Amherst MA

Ok everybody I'm not kidding about the cavity nesters or this!!: Either I have a REALLY, REALLY, REALLY washed out adult female EABL or I've got a MOBL/EABL hybrid! It was noticed today on a tour of my trail today by a 4-H leader who is a birder. Thom and I just went out with the scope tonight and we just can't say it is a normal EABL- nothing like any of us have seen.

She looks like a female WEBL, except her barely visible thrushy chest extends down like a EABL. She has the same gray tones as a female MOBL.

Their babies are 15 days today - probably too old to band, but hopefully I can get her documented via photos. (fingers crossed). Have I gone totally out of my mind? I know a female MOBL was sighted late 2000 in eastern MA. Any ideas???????? :-) H

Haleya Priest Amherst MA
I just witnessed a baby EABL pick up something HUGE and try to eat it. I got out the scope and it was about a 4" long earth worm a good pencil size thick. This thing was about as big as the baby! It took about 20 minutes for the whole thing to happen because the baby couldn't get it down, but at a certain time couldn't get it out either. It stood there the whole time with its mouth open. Its sib stood next to it almost the whole time.

Anyway, once the earth worm had only about a 1/4" to go, it started to crawl back out! Needless to say, EABLs are probably not really equipped to eat
earthworms and isn't a part of their diets unless nothing else is available - in the meantime, I bet this baby is going to have some terrible indigestion!! :-) H

Hi Haleya & All:

If you continue to fill us in on those exciting scenes you capture with that 'scope I will be forced to purchase one!!

Several yrs. ago I was monitoring boxes during a lengthy rainy period & found a small earthworm across the back of a nestling, the parents evidently missed the beak. Later I read somewhere that earthworms are simply not that nutritious for nestlings as they contain large amounts of water. You were right in assuming the fledgling resorted to earthworms due to lack of insects as the parents will do the same thing. This is another reason why I try to supplement their diet with mealworms.

As you say, they resort to earthworms when nothing else is available. Although I am afraid this little "tiger" did it out of sheer ignorance!! He was probably so proud he found his first bug!!! Anyway, for newbies: When your babies fledge and you find a layer of something smooth and flat like caked onto the top of the nest, that is earth worm excretion from the babies. I think they can't digest the dirt, etc. and some babies will die of dehydration from it. Like Betty says, the parents will eat and feed the earthworms when no other food is available - like cold rainy weather. Last year one of my nests had about a 1/4" thick layer of this earthworm poop (no smell) - but all babies fledged regardless. So, no need to worry - but something to simply observe!! :-) H

Subject: Can you tell me?

This is new to me, perhaps you can tell me what is going on in our front yard:

There are two sites 300' apart in our front yard, each site has two boxes 22' apart and one feeder. One site had EABL nest, the other has TRES. Four
EABL fledged around 5/12. I removed the nest around 5/15. On 5/19 the EABL had a new nest completed for the second time in the same nestbox. On 5/26 there were 4 *new* eggs.

About 5/26 I noticed EABL activity in the empty box next to where the TRES live. I was not sure at that time, but now I know it is the same pair from the other site! So, this pair of EABL has now completed building a third nest (at the TRES paired site) while incubating the second set of eggs, *and* they are still taking care of the 4 juveniles!!!

Has anyone seen this before? I wonder if I will see three generations of EABL with the parents. I believe the reason this is happening is due to the abundance of food. Besides having lots of food in the grass around, I also provide mealworms at these two sites. It is really amazing how the one pair can take care of babies, sit on eggs and at the same time have a third nest ready for use after the second fledging... I'll keep you posted.

Hi Ann, Malinda and all. What I find amazing and new (to my knowledge) is that this female has 4 eggs she is sitting on on one site, and at the same time has her *third* nest complete and ready at a different site 300' away. It is like though she is planning for the future. This is intelligent behavior and I think she is taking advantage of the available resources to make as many babies as she can.

I know that three and even four nestings have been recorded. But has anyone seen a female sitting on eggs (her second set) and at the same time have completed a new nest 300' away for her future third nesting? I think this is so neat... I will keep you posted as to what happens next (she may abandon eggs and move, or whatever...)

Subject: Fledgling behavior

Hi all,

There are two week old fledglings visiting my yard with their parents (mother incubating second clutch ) and today I saw one do something that I am curious about. The father bird was sitting on the roof of my hopper feeder (empty - used for winter feeding but still in place ) which he often uses as a perch from which to hunt. One of the fledglings came and joined him begging for food. Dad found something on the ground came back up to the roof and fed the fledgling. Immediately after this feeding the fledgling flattened itself with wings and tail spread right out on the slanting roof of the feeder. I thought it might be some kind of injury feigning but as far as I know only adult birds do that to distract a predator from the young. Anyway there seemed to be no danger around and the father was unconcerned. He flew off to a tree leaving the fledgling in that position. After a few seconds the fledgling picked itself up, fluffed its feathers back into place and followed after the father. Has anyone ever seen this before or know what it was doing?

Thanks

Subject: [bluebird] intraspecific competition
Reply-To: bluebird"at"fsinc.com
Kevin Putman, Yuba City, CA

Hi all, having a really big year for bluebirds here, north of Sacramento. I'd like to toss this question out: over several seasons here, I've seen a number of unusual things happen in bluebird nestboxes. I've found nests full of eggs built right over nests full of eggs. On a couple of occasions, the second nest was built over the first just after the hen finished laying a complete clutch of eggs in that first nest. When I visited said nestbox, I expected to find a hen incubating, but instead I found a new nest with, say, 2 or three fresh eggs, built over the top of that original nest. There are several possible explanations, but it may suggest intraspecific competition for nest site, or perhaps a polygamous arrangement--- Two hens vying for one male? Ya never know what's really happening.

Just recently, I was monitoring a box where there were 3 chicks, about 4 days old; 5 days later, I returned to find no chicks, but 4 fresh eggs. I looked again today and found a hen incubating 5 eggs. So, it is evident that something happened to the chicks and then another pair of bluebirds immediately took over that box ( note only one day allowed in between for the switch).

The thing that was extra strange was that the new eggs were laid right in the old nest where the chicks had been. That is, if another hen was going to lay eggs in that box it would normally build its own nest before doing so, but not this time. ( I've only seen a bluebird hen lay eggs in a nest other than her own one other time: sparrows took over the box, and built their own nest, just as the bluebird was going to lay eggs; I trapped the HOSP; the bluebird hen then hastily laid eggs in the HOSP nest).

Although something--a scrub jay, perhaps--could have taken the chicks, it is also possible that the second pair of blues could have taken over the box, tossed the chicks, and laid their own eggs. Or, again, maybe it was a second hen only (same male). Who knows?

This kind of competition for nest sites is documented among wood ducks: wood duck hens can get in pretty good battles--beating each other up, tossing out eggs, egg dumping, etc. Can intraspecific competition also be prevalent among bluebirds? It may be among hens or among pairs. Can anyone comfirm this? KP

Kevin, your observations on the nest of eggs with a second nest of eggs quickly following in the same nestbox happened to me for the first time this year on a 1-holed golf course trail. I discovered it while pulling out nest material from the bottom to lower the "high" nest. Whether it was caused from bluebird/bluebird competition is anyone's guess. The golf course is monitored very quickly once per week so I don't know if there was a change in adults. My guess had been that a pair nested, the first female was caught and killed and a new pair rebuilt over the failed attempt. The nestboxes in this area *do* have stiff competition with about 90% occupancy, so your intra-species competition theory is feasible. However, my 2-hole trail has the same high occupancy without this ever happening!?! (I find these exceptions intriguing, ask this question again next year and we might be able to find new clues.)

On your nests with disappearing chicks, then a new clutch of eggs . . . could be a raided box with a new pair (possibly displaced from elsewhere at the moment eggs were to be laid?). I use guards or a combination of guards with deeper boxes to keep eggs/chicks from being raided. Jays seem to hang around boxes at the naked-nestling stage (3-4 days old); watch to see if this is confirmed on your trail. I'm assuming they are easier for jays to pick out of the box at that stage. Another local monitor has reported 30-35 eggs have disappeared from his nests this year (an increase over previous years).

Glad to hear your trail is having a banner year!

Good morning. I'm having a mystery that is leaving me wondering. I'll try and keep this short. The first bluebird nesting fledged 4 babies. After they left everything was fine. On the 8th day the female started a new nest. On the 13th day she was missing and has been missing ever since. (6 days now)The male brings the 2 babys here everyday but their are definitely only 2 . The male still defends the box and won't let anything in their. The young are learning to fend for themselves quite nicely. The male still feeds the young the bluebird treats and peanut butter suet that I put out for them so I expect them to hang around as the male has been here steady since late March. Any idea what could have happened to the female and other 2 babies? I find it strange that the three are all missing and that something could have got them all. Just wondering here in Central New York. Elaine

Have you ever heard of bluebirds nesting on top of a window ledge under a covered porch? The nest was probably started by robins or barn swallows as it had a mud and grass base finished with a nice cup of grass. No cavity whatsoever! We just came back from seeing it -- 5 hatched babies and both parents. We tried to get some photos. New one on me.

I also had my first nest last week with 7 eggs. I assume that's pretty unusual this late in the season.?

Sounds like they are trying to scare off the "birds" they see in their reflection in the window glass. We had a major problem with a male EABL doing that last season during nesting -- always in the early morning in our bedroom window. He would flutter against the window, waking us up. This year we have not had that problem, despite having a pair nesting in the same box. I was under the impression that this was fairly common behavior for males, but have never heard of a female doing it. Interesting!

Subject: Strange EABL Behavior?

A neighbor called this morning asking advice. She has an old box (on a
tree, where else?). She wants to put up a proper box on a post, but
has EABL's in the old one. They built a nest a couple weeks back, and
have lef the area for a while. They came back a few days ago, and will
look in the box, then fly to her picture window, where they can see
her, and wing-wave at her, go to the box, and come back to repeat
their performance. She describes it as them wanting her to go to the
box......but then you know we all are tempted to read something into
their behaviors. Any ideas? I told her to go ahead and put up the new
box and see what happens. No HOSP have been seen in her area.

When I read Phil's post the likelihood of the bluebirds' interest in the window reflected image went completely over my head. Thanks to Emily I got on track.

There was a female in my yard two years ago that was interested so much in her window reflected image that she was reluctant to mate and afterwards she failed to perform a number of her parental duties, preferring, instead, to look at her image. I couldn't settle in my mind whether she thought she was seeing another female or if she was just vain - she was a most beautiful appearing female bird.

She attacked the image and the male, I guess having other things on his mind,.would try to get her to move away from the window. Maybe he didn't like his own or their image, but I think he was too smart to be interested in window images. At some point the female quit attacking the image, but she would hang onto the window frame while looking into the glass. I first tried clouding the windows with cleanser to stop the behavior. No joy. She managed to find some spot that would hold her interest. I finally bubbled some aviary wire over the window in an effort to increase the distance between her and the glass. This worked until she found another window. She seldom fed her hatchlings or nestlings, letting the male do most of that work and, too often, she begged to be fed when she came out of the box. On fledge day for her first brood she didn't try to protect her charges. She remained clinging to a window as her fledglings were attacked by grackles and bluejays. I suspect she was a very young bird, most likely from the last brood of the previous season. She did improve as a parent with each of her two remaining broods of that season, but one of her interests remained the windows of the building near her nest. So, Emily, at least one female bluebird got very interested in a window reflected bluebird image. I've seen other females take some interest in windows, however none so much as this one.

As to the birds in the yard of Phil's friend, naturally, I think it is good to have a box more ideally mounted, but I doubt it would change the behavior of the birds with respect to the window. Is that female bird's name "Lassie?" Then, again, maybe the old box contents should be checked. There could be harmful insects in it.

As a further side note: The mate to the "young" female had his wings full trying to raise a family. He seemed to more than coax her to do things like nest build and feed the youngsters and clean the box. While I have forgotten details, one time, I swear I saw that little guy, in frustration, fly away from her to perch on a limb facing away from her. To me it looked like he just shook his head in disbelief a few times as if to say what the hell can I do. He stayed with it though.

Is this strange or not?

For the past three days I have seen (and filmed) a *female* bluebird being very aggressive to her own reflection within the mirrors and windows of our vans. The male sits on nearby perches making a distinct vocalization (different from his 'regular bubbling gurbles'). She is vocalizing in a high pitched and very 'insistent' way.

There have been recent box position changes / additions nearby ... but these changes were made after a destinctly different female had disappeared. The disappearing female had been here most of the winter and I became quite intimate regarding her behaviors and appearance, catching her on film over 300 times so I know she is not the same one that is exhibiting territorial behavior now.

There are 'claim straws' (just a few thin pieces of grass) in all the *older* nestboxes ... but none of the new ones, and in particular, NOT the one nearest to the parked vans.

Oh ... and I have covered the mirrors and placed 'feather guards' (string and feathers) to dangle across the van windows to try and stop this ... The female started darting / flying about ... with urgent vocalizations ... circling me. She made not 'advances' to me ... just flying around me as I applied the covers and guards. She is still out there doing her 'aggressive' thing.

Now I know that having 3 inches of snow fall last night is a bit unusual for central PA, but ... is this female being a little wierd too or what?

Input appreciated.

Grant,
    What do you mean by nesting in two boxes simultaneously??? To answer your other question, your pair that are building will either stop during the cold weather (resume when it warms up) or continue to build. All if fine.

    I don't know how close these boxes are but are you sure it isn't one pair building in both boxes??? Sometimes they make a dummy nest in one box.....  :-)

Subject: Multiple BB Nests Built By One Pair?
Date: Tue, 23 Apr 2002 11:21:33 -0400

Life is interesting with bluebirds. They always come up with something new every year....

There was mention of "dummy nests" the other day and this is a first for me, but I am pretty much convinced that a single EABL pair built 4 nests in 2 sets of paired boxes, 100 yards apart. (The boxes are paired at no more than 15 feet apart.) I watched these boxes carefully as I'm taking part in the Temperature Pilot Study and I wanted to determine which nests needed the nest temp. data logger before the eggs were laid. It was driving me crazy, because every day that I checked, there seemed to be a new nest start. Finally, 5 eggs were laid in one of the four boxes, due to hatch this week. There has been no additional activity in any of the other boxes and no additional BBs in the immediate vicinity of these sets of boxes. By the way, these nests are all complete with cups. Has anyone else experienced this in this many boxes?

The only other thing I can figure out is that when the nest building first started, I did see one male and two females together on a particular occasion. Other than that one time, I've just seen the one male & his mate who laid the eggs. Does anyone think the unpaired female was doing much of this nest-building without a mate? If so, would the paired female allow this to happen?

We are certainly experiencing the same miserable weather that has affected so many parts of the country this spring (and I use the term loosely!) However, I have a story that is unique in the years I have been monitoring.

On April 19, I found three bluebird eggs in a nest. They were cold. On April 27, there was a fourth egg. All were still cold. On May 4, I saw the male fly out of the box and assumed he had been feeding the female but no- there were five eggs, still cold and still no female. On May 11, the situation was pretty much the same.

Caren had sent me a new nest sensor for that nest since it was apparent that the original one missed any incubation. I went out today to put it in the nest and saw the male leaving the box again. I very nonchalantly opened the box and found five new hatchlings! I call it The Immaculate Hatching since I have yet to even see a female this season, let alone any signs of incubation.

So, I guess the morale of the story is never to give up hope- and never to assume that things will go "according to Hoyle"!

Kathy Clark, New Cumberland, PA... Here is a nest box riddle sent to me.. 

any opinions.. I've never heard of it but so what LOL... we all learn from each other.. Please copy to sunshinebb"at"msn.com

Yesterday at the Trout Run Trail, I checked my nest box with the one baby BB. It was fine, looked old enough to fledge, and I observed the parents coaxing it to fledge. It has been in the box since 6/4. It did not show its head in the opening of the box, as they usually do when they are ready to fledge.

Well, today I checked again, did not see the parents, but looked in the box and the baby BB was still there and also saw a new BB egg that was not there yesterday. Is that from the same pair, or is it an egg dumped by another BB? This is very confusing....Please advise.

Wondering if anyone can address this behavior or has seen it before...

We're on our second nesting in our backyard nestbox (fledged five on 5/7, all are doing great). Five eggs in the box that Mom has been incubating are due to hatch any time (today is day 13). Mom has been incubating regularly, nothing unusual noted til today.

When I got home from work, Barry told me that both Mom and Dad BB had been acting strangely all afternoon, and I got to witness it myself as they continued their behavior up til dark. They were both in and out of the box (hadn't seen Dad go in since nest-building time) for brief periods; Mom definitely didn't stay in long enough to be incubating; they were back and forth to our windows, fluttering on them, wing-waving to each other, sitting on our gutters and wing-waving, flying back and forth to the box, to a tree limb, more wing waving, more in and out of the nestbox, back to a branch nearby, etc! This went on and on and on.

I watched carefully with binoculars to see if I could see them carrying out bits of eggshell or something or carrying food in, but didn't see anything like that. Never saw them hunting or eating either.

So, is hatching occurring and is this the way they act? There were no predators in the area, and Barry checked in early afternoon to see that all five eggs were still in the box, intact. I've never witnessed anything like this and would really appreciate the wisdom of the list!

Thanks!

Thanks Ruth.

Mom and Dad BB were still at it (the odd behavior) this morning, making me think that unless the babies have hatched (in which case they aren't feeding them), this is going to be a failed nesting, since Mom was off the nest too long to be incubating. She had been so consistent through Monday, it's strange. Also, these are not inexperienced parents as they've successfully raised five earlier this season.

The odd thing is, if there were wasps in the nest box, why would they still keep going in and out as they were late yesterday. Sometimes one would stay in for a couple of minutes, even. But this morning before I left for work, they would only poke their head in; I never saw either go all the way in, which makes me sad and worried. The female also came and fluttered our windows several times and let me get right up next to her -- she didn't seem scared at all. She almost seemed to want to tell us something...

I'll keep you posted.

Hi Emily, The odd behavior is from the birds seeing their reflection in the window, and trying to chase away the competition. The more important thing you mentioned was a wasp nest in the box. Bluebirds generally will not enter a box with a wasp nest. Right now seems like a good time to remove it while parents are busy fighting themselves off. With only eggs in the nest there is no worry that young will get stung,just you! Removing the wasp nest will not solve the problem of Bluebirds flying up to window but will make it safer for you and young if the female starts incubating pretty soon. The eggs will be ok for several days if incubation has not yet started so concentrate on the wasp problem and then put something up next to the window that attracts birds. They may keep it up or just move to another window. If you can get eggs hatched the parents may start paying more attention to young and spend more time feeding. Good luck, Joe Huber-- When it comes to bird behavior they are unpredictable,nothing is for sure.

Hi Joe,

You must have missed my first post. Mama had been incubating five eggs for 13 days when this behavior began (window fluttering, back and forth to the box and branches nearby, much wingwaving). Why would they just now start noticing their reflection? They had not fluttered at the window at all prior to yesterday, and this is their second nesting in the box (fledged five darlings on May 7).

Also, there is NO wasp nest nor any other insects/predators in the box. We have checked it out thoroughly yesterday and today. The wasp idea was suggested by a couple of folks on the list and was a great idea -- but it did not prove to be the case.

Thanks for your ideas, but unfortunately we are still a loss. I'll post to the list if we ever get to the bottom of this.

Subject: Odd EABL Behavior & Chickadee Questions

My Eastern Bluebirds have a nest with six eggs that are due to hatch this weekend. I have two boxes on the other side of my house. These two boxes are paired and are 100 & 115 feet away from the box with the Bluebird eggs in it. One box in the pair is empty and the other has a Black Capped Chickadee nest in it. I have two questions: On Saturday afternoon when my husband was mowing the lawn area (1/2 acre) around the Chickadee box, both my male and female bluebirds were trying to get into the Chickadee box. It was very cool and I felt that the female EABL should have been in her box brooding the six eggs. They never entered the empty box. My husband made a smaller entrance extender hole to put on the Chickadee box. This seemed to stop the bluebirds from hovering around the Chickadee box. What were the blues trying to do??? My second question is about the Chickadee nest. Last week there were three eggs deep in the center of the nest and under the nesting material. Yesterday, there was four eggs under the material in the center and also one new egg that was totally over in the one corner of the box. This one egg was laying in the open of a perfectly round crater shaped indentation and the egg was uncovered. This looks very strange to me. Is it one and the same female laying eggs in the box or could there be a second female also laying in the box. It seems very odd to me. Any information on this????? Thanks.

1. Mom's being tough and trying to get the kids to come out and fledge while pop still can't stop saying 'no' to the chicks.
2. Mom's been stuck in the box brooding the chicks while pop has been out making a living for the family and now the chicks are big enough she can steal a few minutes for herself.
3. Mom is trying to steal a few morsels for herself because she is getting ready to begin her next nesting as soon as she can get these chicks out of the box and under pop's care and it takes a lot out of a hen to produce those eggs, not to mention sit on them for 15 - 17 days with only brief respites for her own necessities.

House Finches

That's a real bummer!  I have found them dead on my patio, too.  I had some big, plate glass windows in my last home and I finally had to buy hawk silhouettes at the Wild Birds Unlimited store.  They are made of thin black vinyl, and stick on your window by friction to help prevent accidents like this.  I also stuck some "suncatchers" on the sliding doors, (which helped keep me from walking into the closed glass!) It also kept the birds away.  I put the hawks up in the early spring and keep them up until late fall.  I also have found birds drowned in my bird bath a couple times, so I put a large, flat rock in the bath to make it more shallow.  One I filled up with pretty pebbles, and that worked too.  We're all still learning.  The hawks work for me, so you may want to try them.. Barbara in Cloverdale CA I found a dead house finch today, but I don't think it's from the eye disease.  I think the poor fellow flew into my window.  =( When we ordered our house (a modular) I got special windows with the french style panes because i thought  it might help prevent the birds from flying into the windows.... and I think to some extent it has, but this is the 2nd fatality we've had from this in 9 years.... what do other people do, if anything,  to prevent this??

Just received our local wildlife newspaper describing www.flap.org, (fatal light awareness program) a website explaining all the ins & outs of windows & birds.  They believe that some of the current methods used to prevent window crashes are not very effective.  Interesting site. The mention of birdbath drownings, reminded me of one of my mother's experience.  A 5 gallon bucket left overnight in her garden caught 2 1/2" of rain.  The next day she found a small bird drowned.   Farmers use this method to dispatch mice & other varmints.

Thanks Dottie, that website says: " To make the silhouettes more effective you must cover the entire surface of the window, from the outside, with silhouettes or other patterns two to four inches apart" This is what I "tried" to do with my french windows...... there is white strips in between two panes, they are about 6 to 8 inches apart, and I thought for sure this would work when we ordered the house, but unfortunately,  there are birds still flying into the windows. I am going to try to hang something out there that is moving to hopefully keep them from flying into the windows anymore. Thanks for the site there is a lot of good suggestions and ideas on there.

I use window clings for the season. Right now I have up bunnies. You can use them from year to year and they will last quite awhile.  In the fall, I use fall leaves and then snowflakes after that which are good until St. Pat's Day and then I use shamrocks.  We don't even notice them and they don't hurt the view. In fact, they look pretty. For me they work wonderful.  I have large sliding doors on three sun rooms and, if it weren't for window clings, I would have to rethink feeding birds. Now, does anyone know how to keep Hummingbirds from sticking their bills into screened-in porches?  We have to go and push them out and then I have to take something to re-fix the screen.
