Lined Seedeater

Tiny, active songbird with distinctive black-and-white head pattern. Olive above, white below, with yellow wash on sides and rump and white wingbars; adult male’s vivid red-orange crest especially visible when raised. Inhabits montane coniferous forests and more open, scrubby areas with stunted bushes and evergreen growth. Feeds restlessly on small branches, frequently both gleaning and hovering. Song a somewhat strident series of high-pitched thin “tsi” notes; calls similar to song elements.

Large forest guan found in far southeastern Peru, Bolivia, southwestern Brazil, and northern Paraguay, often along rivers. Plumage is mostly black with a white face, crown, nape, and wing patch. It has a bare patch of skin on the throat that may be light blue or white. On older birds this skin patch ends in a wormlike wattle that dangles below the neck. Formerly treated as a subspecies of Blue-throated Piping-Guan; it can be distinguished by the pure white (not buff-streaked) crown and nape, paler blue or white throat patch, and the wormlike wattle (on adults). In some areas, including the Pantanal, individuals with blue and red throat patches can be found; these are likely hybrids with Red-throated Piping-Guan. Mostly arboreal, but sometimes descends to the ground to feed or drink. Song, often given at dawn or dusk, is a rising series of clear whistles. Occasionally rattles its wings loudly in flight.

Range-restricted, gray-and-red spinetail. Found in bamboo and other dense, tangly undergrowth in secondary forest in parts of the Andean foothills of Peru, Bolivia, and adjacent lowlands. Browner than the similar Dark-breasted Spinetail, which has a gray face and underparts. Darker and more reddish on the upperparts and crown than other similar species like Plain-crowned and Pale-breasted Spinetails. Forages singly or in pairs in the undergrowth. Listen for its call: a nasal “nyeck-nyeck.”
