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!

this is just my 2nd year with bluebirds I had another nest of 7 chickadees early this year that all hatched and fledged on the timetable but i have a pair of bluebirds who laid 5 eggs last egg on April 15th 2012 and has been 21 days and none have hatched???the mother sits on the nest still and the male still visits-she though is scared off easy(anytime we open back door)but goes right back on-we did have a couple of cold snaps in between what is longest eggs have gone and still hatched(i might have a record here)

Well If you have ever seen TRES fledge theres no way a baby Blue will make it. I would almost opt to candle the eggs and if there is little to nothing there get rid of them. Is it possable to tell the difference between babies at hatching time? I would want to put them in the Blues nest but that could cause problems too. Lets think babies not eggs here. No way a blue can survive with a TRES Mom, overloading a Blue or having babies hatch days before her clutch could result in dead babies. Yikes this is one for Bet, Malinda or Cornell. Im still thinkin destroy the eggs so no babies ever suffer.

Tim, glad to hear the eggs hatched, hopefully the rest of the nesting goes smoothly. I use photobucket to upload photos to and post on here. It will resize them for you when you upload them there. Donna
