Yellow-bellied Flowerpecker

Small, distinctive, ground-dwelling bird. Upperparts gray, underparts cream white, with black streaking on back, underparts, and crown. Male has black stripe on side of crown, female a rufous stripe. Inhabits dry forest and woodlands. Often forages near forest edges, searching for insects in leaf litter or grass.

Small brown bird with large distribution from Costa Rica to Argentina. Rufous-brown overall with whitish eyebrow and a white stripe on the side of the face. Extensive streaking on crown and underparts separates from Plain Xenops. Compare with Slender-billed Xenops, which occurs primarily in lowland Amazonian forests where Streaked does not and is not as boldly streaked. Usually found singly or in pairs following a mixed-species flock. Occurs in mature forests and edges, from the understory to the canopy, but most often at middle levels. Can be found from the lowlands up to around 2,500 m.

Extremely rare, large, elongated brown warbler with a long slender bill. Fairly similar in appearance to West Himalayan, Chinese, Baikal, and Spotted Bush Warblers, but breeding ranges do not overlap. Like other bush warblers, typically very skulking and furtive, preferring to run instead of fly when threatened. Emerges onto small bushes to sing, producing a dull clicking that would underwhelm a grasshopper. Breeds in weedy and bushy slopes in open alpine and subalpine areas; wintering habitat poorly understood but presumed to be similar habitat at lower altitudes. Very few sightings in recent years.
