Palau Swiftlet

Rather dull, brownish bird found in cloud forest along the east slope of the Andes. Brown with faint buff streaking on head, throat, and breast. Throat is scaled buffy, and tail is rusty. Lack of distinct streaking on lower underparts helps distinguish it from other similar species in range. Usually seen foraging along branches at low to medium heights. Typical song is a series of two to six strident notes; a longer series may be given if the bird is excited.

Dipper endemic to fast-moving streams in semi-humid montane forest with alders in Southern Bolivia and Northeast Argentina. The only dipper in its range. Rare, but fairly conspicuous where it occurs. Often in pairs or family groups, foraging in briskly moving streams for aquatic arthropods.

A medium-sized woodpecker of dense forests, often encountered only through its song, which sounds like maniacal descending laughter; also gives a loud, high-pitched grating chatter. Bright rufous overall, with black banding on the wings and tail, a paler brown head, and a long, bright yellow bill. Only the male has a red patch on the back of the head. May appear dark brown from a distance or when shaded, but often flashes bright orange when in flight. Drums infrequently, if at all.
