The boxes were paired about 10 feet apart,they each began building nest and the both began laying eggs ,Then All of the sudden,The TRES decided they wanted the other box.They moved in and began laying more eggs with the Wren eggs,even carefully adding nesting material under the the Wren eggs.I noticed the Wren was going in the other box where the TRES used to be.I thought for sure they would throw out the TRES eggs and rebuild another nest,But they didn't,she began incubating the TRES eggs.The start of incubation was a week apart,so I couldn't just switch everything.I was surprised some of the eggs hatched.I did contact a rehaber as soon as I noticed what was going on.Since TRES feed in the air,there was no way each Species would have survived once fledging.Here is the surviving TRES from the video,He/She was pulled from the nest just before it was due to fledge.It was released a few weeks later by the rehaber.

I have a small basket hanging on a hook on my covered porch. Usually, Carolina wrens nest in it. But the other day I saw a chickadee fly out of it. I want to take it down and look into it and see if there are eggs. Will that scare her away? It's kinda neat to see a different bird nesting there for a change! I have several old, small baskets and didn't know what to use them for......so I've hung them around for birds.

I watched most of the video (my attention span is shortish) - it seems that incubating eggs (at least for chickadees) is not a matter of just plopping down on the eggs and dozing off. There's a lot of twitching and wriggling and rearranging the eggs and eating snacks brought by the male. I counted nine eggs during one of her times off the nest. I hope all goes well and we get to see hatching and fledging. Claire

Welcome to the world, little birds! And it's time to start feeding them, parents (easy for me to give orders while looking at a computer screen). Thanks for the update! Claire
