Yemen Linnet

Fairly common but local and easily overlooked in the Andes, mainly in canyons and on rocky slopes with fairly dense bushes and scrub. Usually rather skulking; keeps low in bushes and creeps in vegetation, but often sings from atop a bush. Plumage rather plain but relatively dark brownish above with chestnut wings and a dark-centered chestnut tail. Compare with Cordilleran Canastero, of more open habitats; also note differences in song and calls.

Huge black vanga with a rufous back and an enormous blue bill. Rare and localized Madagascar endemic that is found in northeastern rainforest at low and middle elevations. Usually in the mid-story, perching motionless for long periods. Often joins flocks with other large vangas. Most easily located when nesting in a large mossy cup that is placed on a forking mid-story branch. Song is a long, delicate, high-pitched, slightly descending trill. 

Small tapaculo of high-elevation cloud forest in the eastern Andes of northern and central Peru. Male is uniformly gray; female is paler and browner with extensive buffy barring. Similar to several other tapaculos and best identified by range, habitat, and voice. Inhabits understory of wet, mossy forest. Typical song is very long; it starts with well-spaced chip notes and gradually morphs into bursts of rattling trills.
