Plain-backed Sunbird
Anthreptes reichenowi
Small, short-billed, warbler-like sunbird. The distinctive male has a blue bib. The female is drab but can be identified by its small pale eyebrow, greenish back, and overall size and shape. Found in forest at low elevation, mostly close to the coast. Often in forest understory; less conspicuous than a typical sunbird. Most distinctive vocalization is a rapidly repeated “tchew”. Shape, size, and olive-green back separate Plain-backed from other sunbirds.
识别特征
The plain-backed sunbird, also known as blue-throated sunbird (Anthreptes reichenowi) is a sunbird. The sunbirds are a group of very small Old World passerine birds which feed largely on nectar, although they will also take insects, especially when feeding young. Flight is fast and direct on their short wings. Most species can take nectar by hovering like a hummingbird, but usually perch to feed most of the time. The plain-backed sunbird has a disjunct distribution, with one subpopulation in the coastal lowlands of Kenya and north-eastern Tanzania, and another in Mozambique and Zimbabwe. It may be at risk from clearance of lowland forest throughout its range.

Yellowish Flycatcher
Empidonax flavescens
Small greenish and yellowish flycatcher of humid highland forests. Usually found singly, at all levels inside the forest and at edges, sallying for insects. When perched, often flicks tail upwards. Note the peaked crest, teardrop-shaped eyering, overall plumage coloration, and very high-pitched call and song phrases. Range does not overlap with very similar Pacific-slope and Cordilleran Flycatchers, but compare with migrant Yellow-bellied Flycatcher that occurs mainly in lowlands and has a distinctly different call).
Swainson's Spurfowl
Pternistis swainsonii
A large brown francolin with some darker streaks, dark blackish legs, and a distinctive bare red face and throat. It frequents grasslands and savannas where it is bold and conspicuous, standing on open branches and termite mounds to call its loud screeching “kreeeeet-kreeeeet-kreeeet” call at dawn and dusk. Red-necked Francolin differs by having red legs and feet, by often having white plumage on the underparts or face (depending on the race), and by preferring thickets and forest to open habitats.
Thick-billed Green-Pigeon
Treron curvirostra
Brightly-colored and thickset pigeon of the forest canopy, usually seen flying over in pairs or small groups. Distinctive bicolored bill and bright green eyering are visible even from a distance. Both sexes are mostly green. Males have maroon backs, while females are green all over; both have jagged bright yellow striping on the wing edges. Flocks are seen in fruiting trees in lowland and foothill forests, where they often associate with other green pigeons. Gives smoothly undulating “woooOOOO”, often in series.
