Kemp's Longbill

Small and rather drab. Brown above, darkest on head and wings. Grayish-buff below with a grayer throat. Can appear uniformly gray in dull forest light. Dark eye lacks a white eye-ring. Most common in forest but also found in forest edge and brush. Giant White-eye similar but overall darker, with thick orange bill and pale yellowish eyebrow. Dusky’s most common call is a “cheee.”

Unmistakable large black swan with a red bill. When swimming this species is almost entirely black. Wings show extensive white flight feathers when flying. Juveniles are similar but dark-gray. In Australia, compare with Magpie Goose, which has white belly, and white underwing with black tips. Typically found along inland waterways, rivers, sewage ponds, and coastal lagoons and inlets. Sometimes flocks together in enormous numbers on large wetlands.

This rare chickenlike bird has an exceptionally small range on the border between Panama and Colombia. Found on the ground in mature forest from around 1,000–1,400 m. Dark brown overall with a black head, a whitish face and eyebrow merging with a buffy nape, and a white band across upper chest. Lives in small groups, which can be difficult to see. Listen for the rollicking whistled song, typical of wood-quail.
