Purple-breasted Sunbird

A tiny, long-billed bird of forest understory. Brown above and white below with a black crescent across the chest. Note striking facial pattern with white eyebrow and black malar mark. General impression is wren-like with long bill, contrasting eyebrow, and tail usually held cocked. Difficult to see well, as it tends to remain in dense understory growth around treefalls and other gaps in tall rainforest, where it is locally distributed and never common. Usually seen alone or in pairs. Song is a long, descending whistle, repeated at roughly three-second intervals, very similar in tone and pace to second note of Tawny-crowned Greenlet’s song. Harsh scolding note is perhaps the best giveaway to this species’s presence. Generally unmistakable given a decent view; in silhouette could be confused with Long-billed Gnatwren but has much stronger face pattern and is usually confined to dense undergrowth rather than the vine tangles inhabited by Long-billed.

A denizen of mature montane forests wherein it feeds low in thickets and shrubs. Often found in pairs, but sometimes in mixed feeding flocks. Eye-catching, with bright green back and gray crown contrasting sharply with near white underparts. Named for the bold white stripe in otherwise black primaries. Similar Green-tailed Ground Warbler has red eyes, grayer underparts, and lacks white in wing. Calls include high sharp “tsee” and a brief, upslurred “tswee.” Song is a low chatter.

Small, long-tailed Curruca warbler, very similar to Spectacled and Subalpine Warblers. Males are distinctive with very deep rusty underparts, a rusty throat (sometimes paler mid-throat), rusty wings, and a hint of pale buff moustache. Females are pale brown and less distinctive with normally rather warm-toned underparts. Breeds on mountain slopes covered in dense, low bushes, tamarisk scrub, and vegetated desert wadis; non-breeding habitat is sometimes lower in elevation, but typically similarly open and scrubby. Song a scratchy whistle. Call a low "trrrrr."
