Black-streaked Puffbird
Malacoptila fulvogularis
Elegant medium-sized bird found in the mid-story of humid montane forest. Has a large head and a chunky body, with a fluffy appearance. Dark brown, with extensive bold white streaking throughout the head and body, though its wings are only lightly streaked. Look also for its buffy tan throat and white facial crescent shown on some individuals. Found singly or in pairs, and will usually remain quite still as it is perched, occasionally sallying out to go after prey. Usually found on its own, but occasionally joins mixed-species flocks. Listen for a piercing, high, slightly descending whistle.

分类信息
The International Ornithological Committee (IOC) treats the black-streaked puffbird as monotypic. However, the Clements taxonomy and BirdLife International's Handbook of the Birds of the World (HBW) assign three subspecies, the nominate M. f. fulvogularis, M. f. huilae, and M. f. substriata.

分布与栖息地
The black-streaked puffbird is resident on the east slope of the Andes from Colombia through Ecuador and Peru into northwestern Bolivia. "M. f. fulvogularis" occurs from Ecuador south. "M. f. huilae" occurs in the upper Magdalena river valley of south central Colombia. "M. f. substriata" occurs on the east slope of Colombia's Eastern Andes. The species inhabits the understory of several forest types including humid primary and montane forest and open woodland; in Bolivia it also occurs in dry and semi-deciduous forest. In elevation it ranges from 500 to 2,300 m (1,600 to 7,500 ft).

Ancient Antwren
Herpsilochmus gentryi
This antwren is known only from a small area in northeastern Peru and adjacent border areas of Ecuador. It is confined to rainforest that grows in nutrient-poor soils with a specific mineral composition. Note the yellowish underparts, black crown and black eye-stripe separated by a pale eyebrow, and bold white wingbars and tail edges. Similar to Dugand’s Antwren, but male has yellowish underparts and female has a black (not brown) crown. Stays quite high in the trees and often joins mixed-species flocks. Song is decelerating series of notes that rises and then falls.
Yellow-bellied Longbill
Toxorhamphus novaeguineae
A small, sunbirdlike bird of lowland and foothill forest. Long, thin, curved bill with olive upperparts and head. Southern birds have a brighter yellow belly and northern birds are more olive below. Similar to several other species, but Yellow-bellied Longbill lacks the gray chest of Spectacled Longbill and female Black Sunbird, lacks the yellow eye-brow of female Olive-backed Sunbird and lacks the contrasting yellow-throat of the higher elevation Slaty-chinned Longbill. Song, an often descending series of downslurred whistles.
Streak-eared Bulbul
Pycnonotus conradi
Dull brown bulbul with paler underparts and gray streaking behind the ear. Common in lowland open forests and edges, including forested field fringes, parks, and gardens. The common rural (and oftentimes urban) bulbul throughout much of its range. Calls and songs are harsh and somewhat dry-sounding, without the melodic, musical quality of some other bulbuls.
