Killdeer

Charadrius vociferus

A. Wilson

Killdeer are medium-sized birds that grow up to 11 inches long. They are mostly brown with white underneath. Killdeer have two black bands across their chests. They have black bills and a red ring around their eyes.

Killdeer are usually seen in open country, such as fields, shores, marshes, and golf courses. They can be found in our area year-round.

Killdeer breed in the Spring. Males are very territorial and will chase other males away.

Nests are open areas on the ground; sometimes Killdeer lay some grass on it. Besides natural fields, these birds will nest on golf courses, lawns, beaches, rooftops, and even parking lots.

Killdeer eggs are light brown with spots. They camouflage very well with the ground. Both parents incubate the eggs.

Young killdeer hatch from their eggs in about a month. They can run as soon as their wings are dry, and will continue to run after their parents for about a month, until they can fly. Sometimes the female starts a new nest while the male guards the first chicks.

Killdeer usually keep the same mates every year. When it's not breeding season, these birds sometimes form small flocks.

Killdeer eat many insects (aquatic and terrestrial) including: grasshoppers, beetles, caterpillars, ants, mosquito larvae, caddis flies, dragonflies, and true bugs. Other foods include: spiders, ticks, snails, earthworms, centipedes, crayfish, and some weed seeds. They grab their food from the ground, shallow water, and low plants. Killdeer bob their heads as they walk back and forth searching for food.

Killdeer often act as an alarm system for other animals. They have a loud, piercing call.

Nest predators of Killdeer include Virginia Opossum, skunks, Raccoon, foxes, Eastern Chipmunk, mice, and cats. People, horses, and cattle sometimes step on eggs since they are camouflaged on the ground.

Killdeer will try to draw predators away from their nests by using a "broken wing display." The killdeer fakes having an injury and runs slowly so the predator will follow it. When the killdeer gets the predator far enough away form its nest, it flys away.

Predators of adult killdeer include hawks.

Relationship to Humans:

Killdeer don't usually cause any problems for humans, but they don't seem to mind being around them. They are often seen on golf courses, in parking lots, and on top of roofs. They can be helpful when they eat insect pests.
