Rüppell's Robin-Chat

Small finchlike bird with large range from Colombia to Argentina. Primarily found at high elevations in the Andes, but occurs lower towards the southern part of its range. Male is gray overall with stout yellow bill, rufous undertail coverts, and small white mark on wing. Look for white in tail in flight. Female is brownish and streaky with dingy bill. Look for pairs or flocks in open habitats including disturbed agricultural areas and dry grasslands.

Tiny waterbird, the size of an elongated grapefruit. In nonbreeding plumage, they are black above and white below with a black stripe on the side of the neck and a white comma behind eye. Short, stout bill. Horizontal posture like a football floating on the water. Dives frequently when feeding. In winter, only likely to be seen from land following the passage of a storm, otherwise stays well offshore. Found singly or in flocks. Much smaller than guillemots or puffins, with fast wingbeats and low, twisting flight that recalls a flock of sandpipers. Breeds in large numbers in Greenland and Europe; rare at alcid breeding colonies in Alaska. Birds in breeding plumage have an all-black head and chest.

A dark maroon-gray pigeon with a hind-crown and nape that are white in the male and gray in the female. At close quarters the bill can be seen to have a black base with a red-yellow tip, and the legs are reddish-purple. In flight the tail has pale-tipped corners. A scarce and localized resident found in pairs in the canopy of lowland and sub-montane forest in isolated populations in the Albertine Rift and Cameroon. Vocalizations are poorly documented, but reputed to be similar to those of Rameron Pigeon, which is larger than White-naped with a yellow eye-ring, bill, and feet, white speckling on the wings, and no white on the head.
