Asian Rosy-Finch
Leucosticte arctoa
A dark, thickset brown finch. Males throughout most of the species’ range have black faces and throats, and pink-suffused wings and flanks; the Yakutian subspecies is deeper brown on the wings and has no trace of pink. Females have no pink and are paler on the face and throat than males. Breeds above the treeline in barren rocky areas, but descends into lowlands and foothills during the winter. Often forages in open areas such as beaches and fields.

Biscutate Swift
Streptoprocne biscutata
Large swift with a dark body, long scythe-shaped wings and a square-tipped tail. Resembles White-collared Swift, but has an incomplete and misaligned white collar like a white bib and may have a paler face. Roost and nest in caves and waterfalls where it returns at dusk after foraging over the surrounding landscape.
Chestnut-headed Tesia
Cettia castaneocoronata
Adorably round and tailless small ground-dweller; combination of bright white eyering, deep cinnamon-brown head, and yellow throat is unique and unmistakable. Breeds in montane and hill forests, where it prefers densely vegetated wet or damp areas, often in the vicinity of streams and gullies. Winters in scrubby forest and forest edge growth in lower foothills. Forages actively on the ground in deep cover, seldom venturing out into the open. Gives a loud, fluid-sounding “chee-leu-chee-wit,” as well as various sharp and high-pitched calls.
Silver-rumped Spinetail
Rhaphidura leucopygialis
Small, bullet-shaped swift with rather broad-based wings. Dark (glossy blue in optimal light) with extensive silvery rump patch. Named for thin protrusions from the tail, only sometimes visible at close range. Forages aerially over forest and edge habitat, often near water, sometimes in large numbers and among other swift species. Gives a rapid-fire, chattering trill.
