For some reason bluebirds are intent on forgetting their responsibilities and this is a good reason their attempts to nest end in failure. I'm sure they would have gone extinct if it wasn't for us! Unusual indeed. Last season I had one parent (male I believe it was) feeding the hatch-lings, and the female NEVER went in to feed the babies. That's if my memory is serving me correctly. This is my 6th season, so it's getting hard to remember what exactly happened when. In one case here in Ohio, it was 70 degrees one evening - nice and warm - the babies were ALL gaping like crazy! The blues didn't seem to feed their young AT ALL. I was SO mad! This resulted in the ENTIRE clutch starving to death the next day when it was cold, blustery, cloudy, and only 50 degrees. The mom continued brooding but the young were doomed. I pulled the poor things out of the nest, buried them, and called it a day. Sounds like things are getting better. Unfortunately I suffer set-backs nearly every season. This time the 1st egg of the season disappeared. Could have had a full clutch by now! Sometimes it's just irritating seeing these birds become so careless, but so long as the parents stay alive, everything will be okay. I'm just not fortunate to have many successful attempts each season despite doing so many things right. Good luck from here on out! ~Tim~

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!

I would like to invite you to join the bluebird nut cafe forum. It is much more active than this site and we have many veteran bluebirders that can give quick answers. Check us out! http://bluebirdnutcafe.yuku.com/

Very odd things happening with my houses this year. I had bluebirds in one house that laid 5 eggs. For the most part I try to stay away so they don't get spooked. In this case the next time I checked there was one fledgling that I saw but he didn't seem ready to fly away yet. But when I checked 2 days later there were no babies or eggs. The nest was empty. This box was protected with the mesh on the opening. I'm hoping time just flew by and the brood hatched and fledged in my absence! Will the parents start a new brood in the same nest or should I clean the box out for them to start over? I had another box that had activity, 5 eggs layed and a week later no eggs or babies. I fear they were killed since it was an old house from last year and it did not have the protective metal mesh at the opening. I have a nest nearby with the mesh protection. I kept checking and there was no activity or eggs. Then suddenly there was one egg!! I assumed the mom would lay more. I checked for 2 days, still only one egg. The third day the egg hatched with a tiny bald with a little fuzz baby bird. I kept watching from a distance and I did not see the male or female going into the house. I skipped looking inside the box today. I wanted to stay totally away. Tomorrow I will check again. I hope the little guy is okay.... Is it unusual for a female to lay only one egg? I'm thinking that perhaps the pair that were in the other box moved to this box when a predator got their other eggs..... Thus only one last egg to lay??? The box with the one egg is about 20 feet from the empty box. Perhaps this is part of that brood? Can the mom or dad move an egg or did she just lay it in a different box?? I have another box about 100 feet from that one protected with the mesh that some sparrows have taken over. They have built a nest and hang out in front of it on the mesh opening and on top of it but no eggs for well over a month. Perhaps they are the culprits that got the 5 bluebird eggs. Very strange that they built a nest and aren't using it. I know they will build several, one as a decoy or to give the female a choice, but I don't see that they've done that unless they are planning to take over the bluebird box. I will be keeping a watch on that....
