Marsh Ecosystem-Killdeer


Killdeer

Order: Charadriliformes

Family: Charadriidae

Genus: Charadrius

Species: C. vociferous

General Characteristics: Killdeer have the characteristic large, round head, large eye, and short bill of all plovers. They are especially slender and lanky, with a long, pointed tail and long wings. They are brownish-tan on top and white below. The white chest is barred with two black bands, and the brown face is marked with black and white patches. The bright orange-buff rump is conspicuous in flight. Look for Killdeer on open ground with low vegetation (or no vegetation at all), including lawns, golf courses, driveways, parking lots, and gravel-covered roofs, as well as pastures, fields, sandbars and mudflats. This species is one of the least water-associated of all shorebirds.

Special Adaptations: Killdeer spend their time walking along the ground or running ahead a few steps, stopping to look around, and running on again. When disturbed they break into flight and circle overhead, calling repeatedly. Their flight is rapid, with stiff, intermittent wingbeats.
