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 nominate (or originally described) subspecies breeds from southeastern Alaska and southern Canada to Mexico.The killdeer is a large plover, with adults ranging in length from 20 to 28 centimeters (7.9 to 11.0 in), having a wingspan between about 59 and 63 centimeters (23 and 25 in), and usually being between 72 and 121 grams (2.5 and 4.3 oz) in weight. It has a short, thick, and dark bill, flesh-colored legs, and a red eye ring. Its upperparts are mostly brown with rufous fringes, [ its cap, back, and wings being the former color. 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. The killdeer also has a white collar with a black upper border. The rest of the face is brown. The breast and belly are white, with the exception of two black breast bands. It is the only plover in North America with two breast bands. The rump is red, and the tail is mostly brown. The latter also has a black subterminal band, a white terminal band, and barred white feathers on the outer portion of the tail. In flight, a white wing stripe at the base of the flight feathers is visible. The female's mask and breast bands tend to be browner than those of the male. The adult of the subspecies Charadrius vociferus ternominatus is smaller and paler and greyer than the nominate, and the subspecies C. v. peruvianus is smaller than the nominate and has more extensive rufous feather fringes.[
