Diademregenpfeifer 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.
