コフタオビチドリ Anarhynchus falklandicus

Distinctive, rather chunky plover of Patagonian coasts, grassy steppe, and lakeshores with stony and muddy substrates. Found singly or in small groups, sometimes associating with other shorebirds such as migrant Baird’s and White-rumped Sandpipers. Breeding plumage (male averages brighter) has a bright rusty cap, double black breast bands (upper band often incomplete in Falklands). Immature and nonbreeding birds are duller, but still have distinctive double brown breast bands.
