These are photos of a Killdeer. Killdeer are pretty birds that spend a lot of their time on the ground. Not only do they run around more than fly, they even nest on the ground. Their eggs and chicks are so well camouflaged that it's not hard to step on them. That's part of the reason the parents act as if they have broken wings when you near their nest--they want to draw you away from their vulnerable clutch.
