Pesticides, other chemicals, and cats are among the more serious human-provided threats to the birds year round. Widespread, common, and conspicuous, the Killdeer calls its name as it flies over farmland and other open country. [3] Even though the population is declining, it is not decreasing fast enough to be considered a vulnerable species. [37], The intensity of the responses to predators varies throughout the breeding season. [5], The killdeer's common name comes from its frequently heard call. 2005. Age of young at first flight roughly 25 days. [1] It is protected in the US by the Migratory Bird Treaty Act of 1918,[38] and in Canada by the Migratory Birds Convention Act. AgriLife Extension's online Bookstore offers educational information and resources related to our many areas of expertise and programming; from agriculture, horticulture, and natural resources to nutrition, wellness for families and youth, and much more. The rest of the face is brown. [9] Migration to the breeding grounds starts in February[11] and ends in mid-May. There are notable areas where the birds are absent in the heavily forested region of east Texas, and a relatively more uniform presence along the coast. Phone: (979) 845-5777 [15] Up to five replacement clutches can be laid, and there are occasionally two broods. The birds of north central Texas. Sauer, J.  R., J. E. Hines, and J. Fallon. The nominate (or originally described) subspecies breeds from southeastern Alaska and southern Canada to Mexico. Although not threatened as a species, Killdeer are vulnerable to many hazards in the human environments that attract them: vehicle traffic, roadside and agricultural spraying, and oil and chemical contaminants in industrial areas. After they hatch, both parents lead them out of the nest, generally to a feeding territory with dense vegetation under which the chicks can hide when a predator is near. Extreme nesting dates included in the TBBA files among 59 records with nest dates were 20 March and I 8 July. The former feeds the most before and during egg-laying, the least when incubation starts (as there is little time to feed), with a return to high levels after. [26], About 53% of eggs are lost,[27] mainly to predators. Learn more about these drawings. 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 a bird that has benefited from many of the human actions that have been detrimental to other species: graveled road shoulders, parking lots, and even graveled rooftops are favored nesting sites; golf courses, crop lands, heavily grazed pastures and feedlots, and even fresh clearcuts provide for feeding and nesting. [25] In these broods, the young are usually attended by one parent at a time (generally the female) until about two weeks of age, after which both parents are occasionally seen together with the chicks. An example of this is "foot-trembling",[31] where it stands on one foot, shaking the other in shallow water for about five seconds, pecking at any prey stirred up. In The Birds of North America  No. 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. Its familiarity is a function of its A. Jackson. BREEDING HABITAT: For nesting, suitable habitat is almost anywhere that water and relatively bare “ground” can be found. Ground chases occur when a killdeer has been approached multiple times by another killdeer; similarly, flight chases occur when an individual has been approached from the air. They easily survive leaps from low roofs, but a parapet around the edge of the roof may prevent them from leaving. [13] Nests are also sometimes located on rooftops. With increasing aridity to the west, the species becomes increasingly limited to riparian and irrigated areas, but this is a species that might be expected to turn up wherever suitable habitat can be found. In rural areas heavily grazed pastures and   gravel roadsides are favored. [16] The chicks are raised, at least in single-brood pairs, by both parents, likely because of the high failure rate of nests and the need for both parents to be present to successfully raise the young. Suburbia, irrigation, and stock tanks in west Texas have opened up vast areas to Killdeer. e-mail: kaarnold@tamu.edu. Spread the word. The killdeer was described in 1758 by Swedish naturalist Carl Linnaeus in the 10th edition of his Systema Naturae as Charadrius vociferus,[2] its current scientific name. Young are tended by both parents, but feed themselves. Texas Press, Austin, Texas. It has a white forehead and a white stripe behind the eye, and its lores and the upper borders to the white forehead are black. It’s the least you can do. USGS Patuxent Wildlife Research Center, Laurel MD < http://www.mbr-pwrc.usgs.gov/bbs>, Keith A. Arnold Almost as soon as the down of the last-hatched chick dries, parent Killdeer begin leading their brood to streamside, lakeside, drainage ditch-side, or simply wet ground. Buff, blotched with black and brown. Zoom in to see how this species’s current range will shift, expand, and contract under increased global temperatures. Of the TBBA nest records for Killdeer, 27 (46%) were in May.
