Rufous-chested dotterel

The rufous-chested dotterel (Zonibyx modestus) or rufous-chested plover, is a species of bird in subfamily Charadriinae of family Charadriidae. It is found in Argentina, Brazil, Chile, Uruguay, and the Falkland Islands.

The rufous-chested dotterel is 19 to 22 cm (7.5 to 8.7 in) long and weighs 71 to 94 g (2.5 to 3.3 oz). Adult males in breeding plumage have a gray face with a bright white supercilium, a gray throat, and a brown crown. Their breast is bright rufous with a black band below it; the rest of the underparts are white and the upperparts brown. Adult females are similar but duller. Non-breeding adults replace the rufous and gray with pale brown; their upperparts feathers have bright fringes and their supercilium is creamy. Juveniles resemble the non-breeding adult but have darker brown upperparts and breast.
