what kind of bird is that?

what?

I only meant to be doggedly funny, but

Actually, dsvajda (below, herein) identifies it as a Killdeer (bird)

Killdeer

It was there for a while; I don't know if the eggs hatched or not.

Just a couple of weeks ago, one chased me away from a grassy area near the DGMarket. The next week it looked like the are had been mowed flat.

She picked a spot and...there she is, with four eggs. I was doing yard maintenance and stopped short of the nest, realizing where it was once she started with the "broken wing" display. Gonna stay out of there for the next month or two.

And they really need it.
