I found a killdeer nest in the parking lot of a local school.  The nest is in a fairly vulnerable location, so hopefully a lawnmower will not run over it.  Why killdeer choose to nest in parking lots is beyond me, but it seems to work fine for them. When I first got there, mama was sitting on the nest while papa stood guard (actually, I am just guessing. I cannot tell male from female): Killdeer mama sits on the nest as papa keeps watch. I tried to stay as far as possible from the nest, and they seemed reasonably comfortable that I was there.  I got a good shot of mama on the nest:

Killdeer mama sits on the nest After getting her on the nest, I stood up to go.  My back was to her as I packed my camera away.  I heard her call, and I turned around and she was off the nest doing the broken wing thing:

Killdeer mama doing the broken wing deception I have no idea if it was me who scared her, or if it was something else since my back was turned when she left the nest.  I did decide that this may well be my one and only chance to see how many eggs were in the nest, so I got off one shot quickly and then vacated the area.

Two killdeer eggs I will keep an eye out over the next few weeks to see when the chicks hatch.  Incubation is 22 to 28 days.
