Description wikipedia

The tawny-throated dotterel (Oreopholus ruficollis) is a species of bird in the family Charadriidae, the plovers and their relatives. It is found in Argentina, Bolivia, Brazil, Chile, Peru, and Uruguay. The tawny-throated dotterel is 25 to 29 cm (9.8 to 11 in) long and weighs 120 to 154 g (4.2 to 5.4 oz). The sexes are alike and have no seasonal changes in plumage. Adults of the nominate subspecies are mostly rich buff, with heavy dark streaking on the back. They have a white chin, an orange-tawny throat, gray neck and breast, and a small black patch on the belly. Their white underwing shows in flight. Juveniles have a buff throat, less dense streaking on the back, and paler underparts with a brown belly patch. Subspecies O. r. pallidus is very similar to the nominate but smaller and overall paler. Subspecies O. r. pallidus of the tawny-throated dotterel has a limited range; it is found in coastal northern Peru only as far south as the Department of La Libertad. What is assumed to be this subspecies has been recorded as a vagrant in Ecuador. The nominate subspecies is found from southern Peru south through western Bolivia, Chile, and western Argentina into Tierra del Fuego and east through southern Argentina into Uruguay and southern Brazil. It has also been recorded as a vagrant on the Falkland Islands. The tawny-throated dotterel inhabits grasslands, heath shrublands, and fields and meadows. The nominate subspecies is found in the puna of the Andes as high as 4,600 m (15,100 ft). O. r. pallidus is found on the coastal plain of Peru.
