Lucky you with the nuthatches!! I wish I could get them to use nestboxes at my place. Sounds like you maybe should put up a third nestbox for the Bluebirds in case he finds a mate! Good luck!

Hello Michael, First I am glad you found this site, I was happy when I found it to, but I would like to invite you to join the bluebird nut cafe and we will provide you with all you need to know about these birds. It is way more active and you will get fast answers to your questions. Hope to see you there. http://bluebirdnutcafe.yuku.com/ Secondly your bluebird pair have committed to that nest with eggs so they won't abandon it easily. How much rain are you getting? One year I had blues there were several days of rain and no bugs except earthworms around to feed the babies. They didn't survive despite the parents efforts. My guess is your pair has left to find a food source and will return. I do find it odd that they left when you are providing mealworms. I would recommend you ask this question on the bluebird nut cafe site to get other's input. -Tyler

I just did this too! They will abandon the nest if you don't take care of it, ASAP!! tonight if you can!. You need to do a nest change. There is good info on the sialis site about nest changes and how to do it. I got as much dried grass as I could and put it in an empty butter container. I tried to line it with pine needles, but I don't know where my female got hers?!! It took a few days, but then the second egg arrived along with a third! She was incubating a few days until a wren, I think, got two of them. Now they built another nest in my other box.. after all that work!! then you have to take care of the ants. They say grease the pole.. I put the liquid ant killer at the base on a plastic lid covered with a larger lid.. I hoped it would distract them from the nest, but I can't tell for sure if it worked since they moved.. but I didn't see any more ants in there. Good luck and keep us posted!
