Identification
Length 25–29 cm. (10-11½ in.)
Sexes alike. Adults are overall pale buff, with a warm tawny throat patch, gray breast and sides to the neck, a small black patch on the belly, and a narrow white or buff supercilium, black eyeline and grey crown. It is a fairly upright plover with long, slender bill; striking plumage, mainly rich buff with heavily striped back, feathers with dark streaks on pale yellow-buff background. Juvenile similar to adult but lacks buff flanks.
Similar Species
American Golden-Plover lacks white wing-stripe, has grey, not white underwings, and lacks black belly patch.
Distribution
- Coastal central Peru, along Chile to Tierra del Fuego; winters to southeastern Brazil.
- A vagrant to the Falkland Islands.
Taxonomy
Some authorities include it along with the Eurasian Dotterel in the genus Eudromias. However the resemblance appears to be superficial and most authors now merge Eudromias with the typical plovers into Charadrius.
Subspecies
This is a polytypic species. Two subspecies recognized.[1]
- O. r. pallidus: paler overall with grey eyeline.
- Coastal northern Peru (south to northern La Libertad).
- O. r. ruficollis: darker with reduced white chin.
- Southern Peru (irregularly from Lima) south through western Bolivia, Chile and western and north-central Argentina to Tierra del Fuego; non-breeding east to eastern Argentina and southeast Brazil.
Habitat
Dry shrubland, temperate grassland, high-altitude grassland, and pastureland.
Behaviour
Diet
The main foods are beetles (adults and larvae), earthworms and vegetable remains.
Vocalisations
Usually silent. When flushed or in flight gives a vibrating drawn-out whistle prrrrruu on same pitch.
