Pale-bellied Tapaculo
Scytalopus griseicollis
Small and plain gray like most other Scytalopus tapaculos, but look for slightly paler belly and fairly bright tawny flanks without barring. Restricted to the eastern Andes of Colombia, from just south of Bogotá to the Venezuelan border. Acts like a mouse, scurrying around on or near the ground within montane forest and scrubby areas from around 2,000 to 3,300 m. Listen for fast, froglike trill.
识别特征
The pale-bellied tapaculo is 10 to 11.5 cm (3.9 to 4.5 in) long. The nominate subspecies weighs 16.6 to 19.3 g (0.59 to 0.68 oz). One male S. g. morenoi weighed 17 g (0.60 oz) and two male S. g. gilesi 17.5 and 18 g (0.62 and 0.63 oz). The nominate adult is mostly gray, lighter on the underside. Its back and wings are brownish gray. The rump, flanks, and vent are orange-brown. S. g. gelesi has a darker back with less brown and darker (slate gray) underparts. S. g. morenoi has a brown mantle.
分类信息
The pale-bellied tapaculo has three recognized subspecies, the nominate Scytalopus griseicollis griseicollis, S. griseicollis gilesi, and S. griseicollis morenoi. The last of these was not described until 2015. Pale-bellied tapaculo was formerly considered a subspecies of Magellanic tapaculo (S. magellanicus). The putative Scytalopus infasciatus has been variously proposed as a subspecies of pale-bellied or brown-rumped (S. latebricola) tapaculos, as a synonym for Merida tapaculo (S. meridanus), and as a species in its own right ("Cundinamarca tapaculo"). As of 2021, it is considered "inseparable from the nominate" pale-bellied.

分布与栖息地
The pale-bellied tapaculo inhabits the Eastern Andes of Colombia. The nominate is found in Cundinamarca and Boyacá Departments. S. g. gilesi is found in Santander Department, northeast of the nominate. S. g. morenoi is found in northern Santander Department, Norte de Santander Department, and slightly into adjacent Venezuela. It inhabits low scrub in elfin forest and páramo at elevations of 2,000 to 3,900 m (6,600 to 12,800 ft). It is also, but rarely, found in montane and oak forest. Locally it can be found in Chusquea bamboo stands, and it appears to tolerate disturbed and fragmented habitat.

行为
The pale-bellied tapaculo is assumed to be insectivorous but few details of its diet or foraging phenology are known.<p>The pale-bellied tapaculo's breeding phenology is also very poorly known. An adult S. g. morenoi was in breeding condition when collected in August and fledglings of that subspecies were collected in April, June, and September. Fledglings of S. g. gelesi were collected between June and December.<p>The songs of pale-bellied tapaculo subspecies differ somewhat, but all are a trill, sometimes preceded by a single note [1]. The scold call is also a trill [2].

Greater Melampitta
Megalampitta gigantea
A large, rare, ground bird from scattered areas of foothill and lower montane limestone forest. All black plumage with long legs, strong bill, long tail and some bare facial behind the eye. Juvenile has a brown belly. Very secretive and keeps to dense cover. The only large, black, terrestrial bird. More often heard than seen. Voice, a loud, repetitive “choo-oowit!”.
Piping Woodcreeper
Deconychura typica
Fairly small, warm brown woodcreeper with buffy spots on breast and vague buffy eyebrow. Note relatively short, straight bill. Very similar to many other species of woodcreepers but smaller than most others in range; tail relatively longer than most other woodcreepers but this is of limited use in field identification. Focus on overall shape, especially the vaguely “pin-headed” look and scruffy feathers on the nape. Generally found in primary forest, usually following a mixed-species flock. Best identified by voice, though not a particularly vocal species. Song is a long, fast series of medium-pitched piping notes that at first speed up and then slow down at the end of the phrase.
Coppery-chested Jacamar
Galbula pastazae
Sparkling green and rusty bird found in cloud forest along the east slope of the Andes, at higher elevations than other jacamars. Mostly restricted to Ecuador, but it also reaches southern Colombia and extreme northern Peru. Green with reddish belly and undertail, blue crown and throat, and buffy eyering. Female has reddish throat. Long, thin bill may give the impression of an enormous hummingbird. Perches at low to mid levels, looking around frantically before sallying out to snatch an insect.
