Red-billed Pytilia

Often draws attention to its presence by its song: an ascending sequence of “kwa” notes, similar to Green-backed Trogon, but faster. Two subspecies occur in Brazil, Paraguay, and northeastern Argentina with limited geographical overlap that vary in the color of the breast and eyering; the southern one has a red belly and eyering, while the northern one has a yellow belly and eyering. The males of both subspecies have a violet-blue head and breast, a green back, and a white undertail. Females have a dull gray breast and the undertail is gray with white tips. Found in the middle to upper levels of forests and woodlands.

Furtive brown warbler. Brown above and pale below, with a striped vent. Namesake spotting is variable; Himalayan birds have a necklace of dark spots, while central Chinese birds have a much lighter stippled patch on the chest. Extremely difficult to tell apart from non-singing Baikal Bush Warbler where the two overlap: in Spotted, look for a stronger gray wash on the neck and chest, and warmer-toned upperparts. Sichuan and Chinese Bush Warblers can also be similar, but average more warmly-colored, with plainer underparts. Spotted Bush Warbler breeds in dense, shrubby, stunted growth near treeline and winters in reedbeds, wet meadows, and grassy edges. Furtive and skulking; listen for its song, a long series of curious, echoing, clicking phrases: “pritti-kee-kee-dee, pritti-kee-kee-dee.” 

Highly distinctive Taiwan endemic, bright green with a rainbow-hued face in red, blue, and yellow. Inhabits forests, parks, and gardens from lowlands into montane regions. Bold for a barbet, occasionally perching in treetops. Sometimes forms flocks. Vocalizations include frog-like croaking or bubbling notes and hollow bubbling hoots.
