Tooth-billed Bowerbird

Mostly arboreal guan endemic to the semi-humid forest with Podocarpus and alders of the mid-elevation east Andes in southern Bolivia and northeast Argentina. Often in ravines and river basins. The sympatric Dusky-legged Guan is more common, but shows grayish-blue skin around the eye. Tends to perch high in trees, singly or in pairs, and often found by far-carrying vocalizations given from high in trees. Note pale supercilium, dull pinkish legs, exposed red orbital skin and wattle.

A relatively large white-eye confined to Seram. Most conspicuous identification features are the complete gray hood, the white forehead, and the bright white eye-ring. Underparts dirty white, lightly washed with yellow on the base of the undertail. Small groups frequent the canopy of forests in the foothills and particularly in the mountains. Differs from Lemon-bellied and Warbling White-eyes in the lack of a yellow belly or throat. Separated from Seram White-eye by the white forehead. Calls are a combination of often-repeated soft “choy-choy-choy” notes and “tri-tri-tri” calls.

Small antwren of rainforest midstory. Males are pale gray with black and white wing bars. Throat is gray in most of its range, but in southwestern Amazonia the center of the throat is black (but never as extensive as the broad black bib of Long-winged Antwren, which also is overall a darker gray). Females are light buffy tan below, gray above, with no wing bars, appearing more two-toned than very similar but more evenly-colored female Long-winged Antwren. Often can be heard singing in the early morning, an even paced series of rising “wuee” notes at a pace of about two notes per second.
