Killdeer is a shore bird. It runs up and down the shore hunting for fish and insects. A Killdeer will call out "Killdeer". They nest on the ground and when a predator attacks there nest they will try to lure the predator away by pretending its wing is broken so that the predator would focus on the injured bird instead. Once the predator, the Killdeer will fly back to the nest to evacuate it.
