I took this photo of these Killdeer (Charadrius vociferus) in a Maryville restaurant parking lot from my car window. They were just far enough away that I couldn't get them in sharp focus. Killdeers lay their eggs on the ground, often among gravel. The parents will feign injury, dragging a wing as they run away from the nest to distract predators. The babies are precocious, they can run not long after hatching. The birds are named for their distinctive "kill-deer" call.
