Ashy-headed Tyrannulet

A tiny well-named flycatcher with a distinctive bent bill like a broken nose. It is olive-green above with paler yellowish underparts. Note the pale gray eyes. Inconspicuous; typically seen singly in the understory of lowland forest, edge, and second-growth. Best detected by trilling calls. Occurs from Panama to Colombia; no range overlap with similar Northern Bentbill.

Small brown bird with long pointed bill, long pinkish legs, and off-white eye ring. Inhabits rainforest and wet eucalypt woodlands, where it forages for insects mostly in lower and mid-canopy, often on tree trunks; unlikely to be seen on the ground.

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.
