The killdeer (Charadrius vociferus) is a large plover found in the Americas. It gets its name from its shrill, two-syllable call, which is often heard. It was described and given its current scientific name in 1758 by Carl Linnaeus in the 10th edition of his Systema Naturae. Three subspecies are described. Its upperparts are mostly brown with rufous fringes, the head has patches of white and black, and two black bands cross the breast. The belly and the rest of the breast are white. Killdeer inhabit open areas such as sandbars, mudflats, and grazed fields. They are probably most familiar around towns, where they live on lawns, driveways, athletic fields, parking lots, airports, and golf courses. Generally the vegetation in fields inhabited by Killdeer is no taller than one inch. You can find Killdeer near water, but unlike many other shorebirds, they are also common in dry areas. Often seen in dry, flat landscapes, running and halting on the ground in search of insects and earthworms. Although the Killdeer is common around human habitation it is often shy, at first running away rather than flying. When a Killdeer stops to look at an intruder, it has a habit of bobbing up and down almost as if it had hiccupped. Near the nest, Killdeer distract predators by calling loudly, bobbing, and running away. Killdeer are some of the best-known practitioners of the broken-wing display, an attempt to lure predators away from a nest by feigning injury. Pairs of Killdeer tend to stay together for one to a few years. Killdeer nests are simple scrapes often placed on slight rises in their open habitats. Killdeer may make several scrapes not far away from each other before choosing one to lay in. The duplication may help to confuse predators. Nest is a shallow depression scratched into the bare ground, typically 3-3.5 inches across. After egg-laying begins, Killdeer often add rocks, bits of shell, sticks, and trash to the nest. Curiously, these items tend to be light colored, and this tendency was confirmed in one experiment that gave Killdeer the choice between light and dark sticks. Feeds primarily on invertebrates, such as earthworms, snails, crayfish, grasshoppers, beetles, and aquatic insect larvae. Follows farmers' plows in hopes of retrieving any unearthed worms or insect larvae. Will also eat seeds left in agricultural lands. An opportunistic forager, Killdeer have been observed hunting frogs and eating dead minnows. Killdeer adults, chicks and eggs are vulnerable to predation by many different predators, including birds of prey, gulls, crows and ravens snakes, foxes, coyotes, domestic cats, domestic dogs, raccoons, skunks and Virginia opossums. Most noticeable among the Killdeer’s many calls is the high, plaintive kill-deer the bird is named for. Displaying males give this 0.5-second call over and over while in flight. Birds in distress or sounding an alarm make a sharp dee that can intensify into a nervous, bubbling trill. This trill may also be used in courtship displays.
