Could be avian interspecific competition. I check several bluebird boxes. Earlier this year I had one with 6 bluebird eggs. I don't recall ever having more than 5. Anyway, I checked the same box 2 weeks later and a tree swallow had moved in built a nest. No eggs yet. I checked underneath the swallow nest and there was no evidence of any of the bluebird eggs. So best I could figure was that the tree swallow evicted the bluebirds and somehow threw out the eggs.

I have another box in an adjacent field that had 6 chickadee eggs. I checked two weeks later and it now had 5 swallow eggs and 1 BCC egg mixed in. So again, I assumed the swallow threw out the chickadee eggs, but in this case missed one.

Alot of drama going on out there. Unless you are there 24/7, or just happen to be standing there at the right moment, you are never sure.

Thanks,
JT
