Pluvier des Andes Phegornis mitchellii

Unique little shorebird, found very locally in the high Andes on bogs, lakeshores, and gravel bars in rivers and streams. Usually in pairs or family groups; does not mix with other species. Runs and bobs with a nervous gait, and feeds by probing with its weevil-like bill. Flights usually short and low, rather bounding. Despite boldly patterned plumage, it can blend in well with stony substrates. Note black head with a white diadem, a rusty nape, and fine dark barring on underparts.
