Killdeer

Larger, louder, and more numerous by far than its cousin the Piping Plover, the Killdeer (Charadrius vociferus) gets its name from the insistent cries that can be heard over fields, parking lots, gravel pits, and a host of other open spaces throughout spring and summer.

How to Identify Killdeer

Roughly the size of a robin, the Killdeer is much larger than Piping Plover, and has a dark brown back and white belly, with two black rings around the neck. When agitated or in flight it exposes its rufous-red rump.

You will often see Killdeer running across a field or parking lot, stopping at short intervals and making a loud calling noise.

Life Cycle

Killdeer are among the earliest spring migrants to arrive in our area, usually arriving early to mid-March.

By mid-April, Killdeer are present in a variety of open areas, where they will establish territories for nesting. These include fields, pastures, airports, golf courses, playgrounds, gravel pits, beach dunes, unpaved driveways, and even graveled rooftops.

Killdeer usually lay four eggs in a nest scrape lined with pebbles or grass. Both sexes take an equal share in the 25-day incubation period. Once the eggs hatch, the young are fully covered in down and almost immediately can move about and feed themselves. 

Behavior

When a potential predator draws too close to the nest or young, the parent begins a classic distraction display, which includes flopping along the ground with its wings dragging as though injured and constantly flashing its brightly marked tail.

Where Can I See Killdeer

In late summer, small groups of Killdeer are found in open areas near the breeding sites. In late September or early October larger flocks occur in the interior river valleys and the southeastern portion of the state. By mid-November, most individuals have departed for wintering grounds in the southern United States. A few linger or attempt to overwinter at coastal locations.
