They generally lay four eggs, but we have only seen a maximum of three surviving chicks after a few days. A good indication that they have eggs or young is the extreme noise that they make. They will often fly at both people and other animals in defense of their eggs and young. Masked Lapwing chick hiding in a cow footprint!

The first eggs were laid in the first week of July, which is the case each year. Pied Oystercatcher sitting on eggs in the nudist area of Cable Beach.

A breeding bird atlas is a special kind of book. For the nature lovers and birders who participate in breeding bird surveys, the atlas represents hours, often hundreds of hours, of volunteer time spent within a community of citizen scientists doing what they love, observing birds. So, what exactly does a breeding bird atlas contain?

Especially when I compare it with the other cowbird present in central Mexico, the Brown-headed Cowbird. Instead, they lay their eggs in other species’ nests, and let those nest-making birds (often significantly smaller than the cowbirds) raise their young. Both (in fact, all) cowbirds are obligate brood parasites.

Of course, a lot of the mammals would be hiding.
