Western Dwarf Hornbill
Horizocerus hartlaubi
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 Western Dwarf Hornbill has a less well-defined border between the dark chest and white belly, and only Western 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.
识别特征
It is black with a curved beak and a wide white brow above its eye.
分类信息
The western dwarf hornbill was formally described in 1861 by the English ornithologist John Gould based on a specimen from "Western Africa". Gould coined the binomial name Toccus hartlaubi. The specific epithet was chosen to honour of the German ornithologist Gustav Hartlaub. This species was previously assigned to the genus Tockus but is now placed in the genus Horizocerus that was introduced in 1899 by the American ornithologist Harry C. Oberholser. The western dwarf hornbill was formerly considered to be conspecific with the eastern dwarf hornbill (Horizocerus granti) with the English name "black dwarf hornbill".

Dimorphic Dwarf-Kingfisher
Ceyx margarethae
A small kingfisher of lowland and foothill forest. Deep blue above with bright orange underparts, an orange spot between the bill and eye, a white throat and patch behind the cheek, and a bright red bill and legs. Blue upperparts can be dark or pale. Somewhat similar to Philippine Dwarf-Kingfisher, especially from the front or below, but Dimorphic has bright blue head and back. Voice includes various high-pitched chips, trills, and squeaks.

Black Scoter
Melanitta americana
Plump diving duck, typically seen in flocks in coastal areas. Males are completely black with bright orange knob on the bill. Females are brown overall with pale cheek and contrasting dark cap. Note potbellied shape and rounded head in flight. Typically coastal, but migrates over land especially in the Northeast U.S. Often gathers in tight flocks. Dives frequently, feeding on aquatic invertebrates. Breeds on ponds in Arctic tundra.

McConnell's Spinetail
Synallaxis macconnelli
Dark, long-tailed, sparrow-sized bird of dense thickets. Body plumage is mostly dark gray with a bright rufous cap and wings. An uncommon and patchily distributed resident of tepui slopes and lowland forest; often found near large rock formations and in old disturbed areas in rainforest. Stays close to the ground, rarely emerging from dense cover. Occurs in pairs or small family groups that forage unobtrusively for insects and do not follow mixed-species flocks. Voice is only audible at close range but is usually the first indication of this bird’s presence: it is a low, gravelly note, given repeatedly and irregularly, often sped into a rolling churr. Pale-breasted Spinetail has a similar plumage pattern, but McConnell’s is much darker and occupies forested habitats that Pale-breasted avoids.
