Range / Habitat: Killdeers frequent a variety of open habitats such as fields, meadows, gravel bars, and mudflats throughout the United States and most of Canada.

The Killdeer is a common breeding shorebird. It occurs in a number of unforested habitats, including swales and coulees in sagebrush, farmland, grasslands, city park playing fields, residential lawns, gravel parking lots, and gravel roofs. The basic requirements for foraging are a sandy/gravelly substrate, and nearby wet or muddy areas.

Diet: Killdeers feed mainly on ground invertebrates such as earthworms, beetles, grasshoppers, and snails. They occasionally eat seeds and small vertebrates.

Nesting: They require a sandy or gravelly substrate for nesting near a wet or muddy area where they can forage.

Behavior: Although many species of birds pretend to have a broken wing to lure predators from their nest, the Killdeer is the one most commonly seen performing this distraction display.

The broken-wing act used to lead predators from the nest would not keep a cow or horse from stepping on the eggs. To guard against large hoofed animals, the Killdeer uses a quite different display, fluffing itself up, displaying its tail over its head, and running at the beast to attempt to make it change its path.
