“Loud kill-deer! kill-deer! call”

What the Killdeer sounds like

A medium-sized plover (shorebird) with a brown upper body and white underparts marked by two bold black bands across the chest. The face shows a white forehead and brown cap, with a black band running through the eye forming a mask. The rump is bright rufous-orange and very visible in flight. Long legs and a relatively long, pointed tail give it a lanky appearance on the ground. True to its scientific name (vociferus), it's often heard before seen, calling loudly in flight.

How to tell it apart

Listen for:The Killdeer is more noted for calls than for any melodious song. Its signature sound is a loud, piercing two-syllable call that sounds like "kill-deer!" often given in series. This ringing, high-pitched call serves as both a contact call and a territorial proclamation. A rapid, excited "killdeer killdeer killdeer" may be heard when the bird is especially agitated. (Killdeer have no complex musical song—these ringing calls are their primary vocalizations.) Often written as “Loud kill-deer! kill-deer! call”.
Don't confuse with:The Semipalmated Plover — much smaller (about 7.25"), with a single black chest band.

Where you'll hear it

Open ground near water or in dry uplands – highly adaptable. Common on lawns, golf courses, parking lots, gravel roads, and agricultural fields. Also found on mudflats, shorelines, and the margins of ponds. Killdeer often live in human-modified habitats (ballfields, construction sites) as long as there is flat open ground. Nests on bare gravel or soil with little vegetation. In winter and migration, also uses coastal wetlands, beaches, and tidal flats.

Killdeer can breed quite early; in some regions nesting begins in late winter or early spring. They often raise two broods per year. Notably active at dusk and after dark – their loud calls are commonly heard at night as they fly circles overhead. This nocturnal activity is partly why one can hear Killdeer calling even when it's too dark to see them. During breeding, they perform distraction displays (like the famous broken-wing act) to lead predators away from nests. In non-breeding seasons, they gather in loose flocks on good feeding grounds such as mudflats.
