The birds abandoned this nest or were eaten by the neighborhood mouser cat and the cat does hang out in the area of this nest around my shop. He keeps the mice out of my shop though so I can't complain. The nest was all of 5 feet from the ground and easy climbing for a cat. I can't quite identify the birds though. This would be some north east Texas birds. Most common are doves which lay white eggs and mocking birds. I don't see many robins around. I always am sad to find things like this but the adult birds will abandon a next if they are in danger. They can always build and lay more eggs I think is the rationale for that. I think they might be mockingbird eggs. Bad choice for a nest site though. So what thinks the wild bird egg experts, mockingbirds? It has always been a fascinating mystery to me how these birds make eggs that look like this.
