Hi Kathleen- I'll address you since the other posts are old. I am so very sorry that you have experienced this. Did you read what the responses were to the older post of one that lost a bluebird on the nest? I would just repeat everything that they said. If absolutely no sign of injury, I would suspect lawn pesticides, but considering what happened to the 1st person that posted & didn't see signs of injury on her bluebird, it did turn out to be house sparrows. I would highly suspect this. Do you think the female is dead too? If so, again I would be suspicious of HOSP. Answering your question, the male would not starve himself, nor is he able to brood eggs. If the female died too, the eggs wouldn't have hatched because the female is the one to incubate the eggs. She has a brooding patch on her lower abdomen that the male doesn't have. If she is alive, she may not be returning to nest because of the failed nest situation, especially if there was foul play. Make sure you know that she is not returning before removing the nest & eggs. If she is alive, she will probably try to find a new mate. Without repeating too much, make sure your birdhouse is on a pole with a baffle & put a sparrow spooker up after the 1st egg. If you know for sure that the nest has been abandoned & you don't get any activity, you may want to change the location of the box (birdhouse). If you immediately get a house sparrow setting up shop, then you'll know that was most likely the culprit. Again, if female is not returning, now would be the time to get a Van Ert trap for your house to trap the male & female HOSP. If you do, make sure you are monitoring every hour if possible so you don't trap a native bird. They can die in there if without food for too long. One of the previous posts left a website for the Van Ert trap. Again, the previous posts left great advice for your situation. This site is not as active as it used to be for bluebirders, so you may want to post to bluebirdnut.com. Lots of bluebird experts are on that site like this one used to have. That's where I go whenever I need advice. BTW, I lived in Atlanta for ten years (live in AL now). Very sorry to hear about your bluebird tragedy. Hope you'll have another pair come for a future nesting, but definitely get that sparrow spooker!

She's just insecure. She is trying to chase away the "other woman" (she sees her reflection). Once she has eggs to occupy her time, hopefully she will settle down. Give her time. Bet has some suggestions on her web site; more often it is the male who does this. Bluebars Here is a link that might be useful: http://www.sialis.org/windowstrikes.htm

Papa will sometimes stay in the box but he will not incubate them. Bluebirds can sneak in and out during the incubation phase so I wouldn't be surprised if they were there and you didn't know it, especially if the box is not in an area you see often.

I really hope you don't "pick" off the male bluebird. How long are you waiting to see if the bb eggs hatch?? I have not heard of that many eggs not hatching.
