what bird has a white ring around its neck
Killdeer The killdeer is a relatively large plover, with adults ranging in length from 20 to 28 centimetres (7.9 to 11.0 in) and having a wingspan between about 59 and 63 centimetres (23 and 25 in). It is usually between 72 and 121 grams (2.5 and 4.3 oz) in terms of weight.[6] It has a short, thick, and dark bill, flesh-coloured legs, and a red eye ring.[9] Its upperparts are mostly brown and fringed rufous,[6] with its cap, back, and wings being the former colour. 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 that is black on its upper border.[9] The female generally has a browner mask.[6] The rest of the face is brown. The breast and belly are white, with the exception of two black breast bands[9] (although the female's bands are usually more brown).[6] 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 juvenile is similar to the adult.[9] The subspecies Charadrius vociferus ternominatus is smaller and more pale and grey than the nominate, and the subspecies C. v. peruvianus differs on the basis of its smaller size and more extensive rufous feather fringes.[6]
