Killdeer

On of my favorite birds and we seem to have many.
Which is surprising since they lay their eggs on the
ground. If you (or anything else) approach the nest they
act like their wings are hurt or something and run off
trying to get you to follow them away from the nest.

Their call is exactly like "kill deer" and that's why they
have that name I suppose.
(Wiki supplied the image for me - easier that way)
