I put up a birdhouse with a camera inside. Bluebirds moved in and after the second egg was laid, another bird came and took one egg. The next morning the mom laid another egg and 20 minutes later that egg was also taken. The mom has come back and appears to be caring for the remaining egg, but I’m wondering what kind of bird this is that is stealing the eggs.
I’ll post the video, maybe someone can tell me what kind of bird it is and how to prevent it.
in the first theft, the bird pecked at the egg and then picked it up by pinching it or poking a hole in it. The second time, the bird opened its beak enough to put the egg in its beak.
Could the mom be moving the eggs?
Thanks for any help.
It looks like a female Brown Headed Cowbird, and this is precisely what these birds do. Have you examined the remaining egg? If it was a cowbird, she would have laid her own egg for the Bluebird adults to raise.
