Brown Prinia

Unique among storm-petrels in having an entirely silvery-gray plumage. Aside from overall plumage color, look for contrasting dark underwings, dark mask around eye, and deeply forked tail. Breeds on offshore islands across the North Pacific, from Japan to California. Fairly common over cool water, often not far from shore. Found singly or in large flocks, often mixed with other storm-petrels.

Attractive small flycatcher of open and semiopen scrubby habitats in the Andes. Often in rocky valleys and gullies and in open Polylepis groves. Usually seen as singles or pairs, perched quietly at low to middle levels in bushes, dropping to the ground to snatch prey. Combination of bold white eyebrow and rusty underparts is distinctive. Compare with Brown-backed Chat-Tyrant in northern part of its of range.

Spectacular male shows diagnostic maroon sides to head and collar, iridescent metallic blue-green forehead and crown, blue shoulder, moss-green back, and yellow rump. Underside is uniform bright yellow in both sexes, although female is entirely olive above. Juvenile resembles female but with pale legs. Singles and pairs inhabit forest, shrubbery, and plantations in lowlands and lower hills, often joining mixed-species flocks. Female can be separated from female Black and Brown-throated Sunbirds by bright yellow underparts and lack of yellow eyebrow. Gives high-pitched “tzeeet” calls. Song is an undulating trill.
