Wow, in all my years of having nest boxes with tree swallows and blues I have never seen that. I too would like an update on how this nesting turned out. Definitely looks like a tree swallow nest with all the feathers. Very interesting. Was it initially a tree swallow nest and blue laid her eggs as well?
wow that an odd one, so who is raising them?
The tree swallows
Darlene, keep us posted on how the bluebirds do, and if they manage to fledge from the Tree Swallow nest. Best of luck!
wondering how the birds all did, who fledged?
