Deb and I were walking around the yard this evening and suddenly this bird starts dancing, squawking and making runs at us.
So I looked it up: These birds will frequently use the "broken-wing act" to distract predators from their nests. This involves the bird walking away from its nesting area holding its wing in a position that simulates an injury and then flapping around on the ground emitting a distress call. The predators then think they have easy prey and are attracted to this seemingly injured bird and away from the nest. If the parent sees that a potential predator is not following them, they will move closer and get louder until they get the attention of the predator.
It does look broken!
Killdeer nest on open ground, often on gravel. They may use a slight depression in the gravel to hold the eggs, but they don't line it at all, or line it only with a few stones. Since there is no structure to stand out from its surroundings, a killdeer nest blends marvelously into the background. Furthermore, the speckled eggs themselves look like stones.
