I.D. this bird? - killdeer

Was picking rocks in the field the other day, and this mama bird wanted to make sure we didnt mistake her eggs for rocks.

Can anyone tell me what bird this is?

It's a killdeer. They nest literally in the open, like in pasture. I mowed around many of them. If she gets disturbed too much she'll abandon the nest.

Thanks!

She went back and sat on the eggs as we moved along, so I hope she is still committed to the nest.

Ill have to go back and check it out next time Im there.
