Black-collared Swallow

Graceful pale tern with extremely long forked tail. Named for faint rosy wash on belly. Bill color varies geographically; Old World birds arrive on breeding grounds with a black bill that turns to red, while New World birds arrive with a red bill that turns darker. Similar to Common Tern, but notably whiter wings. With practice, look for shallow, choppier wingbeats to distinguish from other tern species. Widespread across the globe but local, breeding in scattered colonies, often on offshore islands. Can be found mixed in flocks with other terns on beaches, mudflats, or estuaries. Listen for harsh two-parted call "chivick."

A small eagle of lowland and montane forest. Stocky body with streaky chest. Finely barred and fairly broad wings and tail fanned out in flight and black wing tips. Often soars low over the canopy. Pygmy Eagle has a different shape than the numerous sparrowhawks and goshawks, with a shorter, broader tail. Much smaller than other eagles. Similar in size to some kites but different underwing pattern. Call, a simple, high-pitched “piwit!” in flight.

Unusual, chunky, short-tailed, crested, yellow-eyed member of the vanga family. Males are strikingly black-and-white, with a small white patch at the front of the wing. Females have a chestnut back, blackish head, and pale underparts. The wings are short and rounded, and the flight is weak. Found in the canopy of humid forest, at low and middle elevations, often along forest edge and clearings. The variable song consists of slurred whistles. Calls include rasps and clearer bulbul-like notes.
