Choco Brushfinch
Atlapetes crassus
This chunky bird is dingy yellow below and dark brownish above with a tawny crown. Sexes similar. Could be confused with Yellow-breasted Brushfinch, which is found at higher elevations and has a brighter rufous crown. Pairs or small groups are found foraging in the lower levels of montane forest, edges and tangles, often clambering around a couple meters from the ground. Found from around 600–2,500 m.

Adults weigh from 29.5 to 40 g (1.04 to 1.41 oz) and are 16 to 18 cm (6.3 to 7.1 in) in length. The adult's upper parts are olive to black and the underparts yellow with an olive wash on the flanks. The sides of the head are black with a yellow crown stripe and throat. Juveniles are dark brown above and lighter brown below with a rufous crown.
分类信息
The Handbook of the Birds of the World (HBW) and the Clements taxonomy consider the choco brushfinch a subspecies of tricolored brushfinch (Atlapetes tricolor) but note that other authors have proposed it as a full species. The International Ornithological Congress (IOC) has accepted it as a full species.

The choco brushfinch is a year-round resident of Colombia's western Andes and western Ecuador. It inhabits open cloud forest and the undergrowth of openings in and edges of humid forest and secondary woodland. It is found primarily from 600 to 2,300 m (2,000 to 7,500 ft) though there are scattered records from lower and higher elevations.

行为
Little is known about the choco brushfinch's diet. It is known to forage up to 10 m (33 ft) above ground, in contrast to many other brushfinches which forage mainly near the ground. It forages alone, in pairs, or as a member of a mixed-species flock.<p>Little is known about the species' nesting phenology as well. Observers have reported nest-building in Colombia in November, February, and May; eggs in April; and fledglings in June and July. A reported nest was a thick cup placed near the ground; it contained one white egg with dusky spots.

Robin Accentor
Prunella rubeculoides
A distinctive and common inhabitant of high-altitude open spaces such as pastures, steppelands, and mountain valleys. Bold and confiding, often visiting villages and towns where it forages for scraps with snowfinches, mountain-finches, and other accentors. Combination of ash-gray head, orange breast, and white belly is unique amongst the birds in its region.
Moluccan Brush Cuckoo
Cacomantis aeruginosus
A fairly large cuckoo with uniformly dark gray upperparts, head, and throat, with deep chestnut below. Juvenile is brown and heavily barred all over. Confined to forested hills in the Moluccas. Distinguished from Brush Cuckoo by its preference for dense habitats, and by the extension of the chestnut color to the chest. Song is also faster than Brush Cuckoo’s. Piping whistles include “wit-wit-wit-wit…” uttered at relatively level pitch, and piping notes, “pip-pip-pip-pip-pip-pipPIPPIPPIPPIPIPIPPIPIPIPIP…”, getting louder and faster by the end.
Patagonian Sierra Finch
Phrygilus patagonicus
Attractive small “finch” that is actually a tanager; found in humid forest and wooded habitats in southern Chile and adjacent Argentina. Despite the name, not really a bird of dry Patagonian habitats. Often in groups, especially in winter, and feeds from the ground to high in trees. Male has a gray hood and distinctive golden back. Female and immature are similar to Gray-hooded Sierra-Finch, but are more extensively yellow below and the whisker marks are weaker.
