Juveniles: similar coloration to adults but duller.
Habitat and behaviour: easily recognised by its plumage, it is found in medium-sized scattered flocks that forage by stops and starts. When still they stand erect on the alert. Rather wary and skittish. In general they are silent although before taking off and during flight they utter a whistle-like sound.
Unlike most plovers that inhabit water bodies or humid areas, the Tawny-throated Dotterel typically frequents slopes, fields and plateaus of the arid Patagonian steppe and the high mountain plateaus where in summer it encounters habitats similar to that of the steppe.
The nest is a hollow on the ground, where up to four buff- coloured eggs are laid with irregular black spots all over. Its breeding range is the Patagonia and Andean region. In autumn it migrates to the north in large flocks.
Range: distribution includes Patagonia from Neuquén and Río Negro to the north of Tierra del Fuego; occasional visitor on Islas Malvinas; in its migratory dispersal it reaches as far north as Buenos Aires, Entre Ríos, Santa Fe and Córdoba. Also in Chile from the Chilean Tierra del Fuego to Arica and, further north, up to Bolivia, Peru and Southern Ecuador.
