Eastern Dwarf Hornbill
Horizocerus granti
A small, dark forest hornbill found predominantly in primary forest subcanopy, where it prefers areas with abundant vines. This species is unique in its overall dark coloration and its broad white eyebrow that extends to the back of the head. The only similarly-sized forest hornbill in its range is the more reddish Red-billed Dwarf Hornbill, but Eastern Dwarf Hornbill has a less well-defined border between the dark chest and white belly, and only Eastern Dwarf Hornbill has the broad white eyebrow behind the eye. Voice is a repetitive “yep yep yep yep” that can be repeated at length, sometimes accompanied with a howl.
分类信息
The eastern dwarf hornbill was formally described in 1895 by the German orthithologist Ernst Hartert based on a specimen collected near the Aruwimi River, a tributary of the Congo River, during the Emin Pasha Relief Expedition led by Henry Morton Stanley. Hartert coined the binomial name Lophoceros granti. The specific epithet was chosen to honour the Scottish ornithologist William Ogilvie-Grant. This species is placed in the genus Horizocerus that was introduced in 1899 by the American ornithologist Harry C. Oberholser.

Lemon-browed Flycatcher
Conopias cinchoneti
Medium-sized, relatively slender kiskadee-like flycatcher. Yellow below and olive-brown above. The obvious broad yellow eyebrow makes this species relatively straightforward to identify. Pairs are uncommon in the foothills and lower subtropical zone of the Andes from around 800–2,000 m. Often found perched in the canopy at the forest’s edge or in a clearing.

Gray-headed Bullfinch
Pyrrhula erythaca
Striking chubby songbird with a black “robber’s” mask. Male is pearly gray overall with an orange breast patch. Female is warm brown overall and lacks the male’s breast patch. Both sexes have a glossy black tail and wing markings. Breeds in coniferous and mixed montane and foothill forests; sometimes descends to lower elevations during the winter. Song is a chattering series of whistles and distinctly dry and raspingly creaky notes. Calls are soft and mellow-sounding, usually a “poo-yee” or “pooe” note.

Saffron-crested Tyrant-Manakin
Neopelma chrysocephalum
A small, inconspicuous bird, much more often heard than seen. Most easily recognized by its striking pale orange eyes; also note gray face and longish bill with pale mandible. Yellow crown patch, though large, is difficult to see in the field. One of the characteristic bird species of white sand forests, occurring in both scrubby and taller forest types. Feeds on fruit and may be seen at fruiting trees and shrubs, though it tends not to be as numerous as other manakins. Best detected by its incessant call: a nasal barking, rather similar to call of Dusky-chested Flycatcher. Display song of male is a bizarre series of twangs, unlike any other bird species in range. Distinguished from Pale-bellied Tyrant-Manakin by paler, oranger eye and by yellower belly.
