To the Beauty of Birds

The Killdeer (Charadrius vociferus) is a large plover found in the Americas. It was described and given its current scientific name in 1758 by Carl Linnaeus in the 10th edition of his Systema Naturae. There are three subspecies. The killdeer's common name comes from its often-heard call. Its upperparts are mostly brown with rufous fringes, the head has patches of white and black, and there are two black breast bands. The belly and the rest of the breast are white.

The non-breeding habitat of the killdeer includes coastal wetlands, beach habitats, and coastal fields. Its breeding grounds are generally open fields with short vegetation (but locations such as rooftops are sometimes used); although it is a shorebird, it does not necessarily nest close to water. The nest itself is a scrape lined with vegetation and white material, such as pebbles or seashell fragments. This bird lays a clutch of four to six buff to beige eggs with dark markings. The breeding season (starting with egg-laying) occurs from mid-March to August, with later timing of egg-laying in the northern portion of the range. Both parents incubate the eggs for 22 to 28 days on average. The young stay in the nest until the day after being hatched, when they are led by their parents to a feeding territory (generally with dense vegetation where hiding spots are abundant), where the chicks feed themselves. The young then fledge about 31 days after hatching and breeding first occurs after one year of age.

The killdeer primarily feeds on insects, although other invertebrates and seeds are eaten. It forages almost exclusively in fields, especially those with short vegetation and with cattle and standing water. It primarily forages during the day; but, in the non-breeding season, when the moon is full or close to full, it forages at night. This is likely because of increased insect abundance and reduced predation during the night.
