Yellow Warbler

Medium-sized tern with thick black bill. Very pale overall with black cap in breeding plumage. Legs black. Nonbreeding plumage shows small dark cheek patch. Found both coastally and inland in a variety of wetland habitats, including beaches, mudflats, freshwater marshes, and even wet fields. Occasionally joins flocks with other terns, but more often seen singly or in pairs. Graceful in flight; swoops over ponds and marshes where it grabs invertebrates from the surface. Formerly considered part of Gull-billed Tern, and limits of the range of that species and Australian in New Guinea and southern Indonesia poorly understood.

Chunky black and white bird with a stout bill. Ranges in lowland and foothill rainforest west of the Andes in Ecuador and far southwestern Colombia. Note orange forehead and large white spots on the lower back. Male has white underparts with streaked flanks; female has black throat and breast, and white scaling on the back. Male can be distinguished from Five-colored Barbet by white underparts, crown, and nape. Typically stays high in the canopy, where it joins mixed-species flocks of tanagers and other small birds.

A large, long-tailed, streak-backed upland cisticola. Note the pale tips to the tail and the brown cap. Generally scarce and highly localized. Found in woodland and scrub on rocky hillsides. Extremely similar in appearance to Rattling Cisticola, and best distinguished by song, but also separated by the unstreaked brown cap and less distinct streaking on the back. Also similar to Ashy Cisticola, but richer brown overall, with an unstreaked cap. The calls are “chit” and “pit-dit” notes, which usually precede the song: a quick descending series of scratchy notes, similar to the song of Ashy Cisticola, but shorter, faster, and with less variation in pitch.
