Long-tailed Glossy Starling

Small yellow warbler found in the understory of Andean forest and scrub from around 2,500-3,500m. Olive above and brighter yellow below, with bright yellow eyebrow and black crown. Sexes similar. Compare with Citrine Warbler, which does not show a black crown. Fairly common. Pairs forage low, often among mixed-species flocks, where they can be difficult to spot among the dense scrub and bamboo. Frequently detected by accelerating series of musical chips.

Compact songbird with short bill. Males in much of range are olive above, yellow below, with white throat set in black head; males and females on Norfolk Island are olive-brown with yellowish underparts (brightest on undertail). Females vary across range, with eastern birds having some amount of yellow on the underparts and western birds (formerly treated as full species, “Western Whistler”) being gray-brown above and pale below, lacking yellow. Olive Whistler much browner below, with well-defined whitish bib. Inhabits a great variety of habitats. Bright, whistled song varies, but often has a whip-like ending.

Yellow-bellied trogon with yellowish eyering and bill. Male has shimmering green-blue upperparts and chest; female is brown. Underside of tail barred black and white with large white tips. Upperside of tail usually coppery-green (browner on female). Found in forested areas, usually sitting still at low to middle heights (often lower than other trogons in range). Male from Gartered Trogon by head and chest color (greener, not cobalt blue), yellower bill, and voice. Brown color of female is distinctive, unlike slaty-gray of female Gartered. Listen for song, a slow, evenly-spaced series of 5-9 slurred whistled notes.
