Piculus leucolaemus

Male has red crown and mustache stripe; female has red only on hindcrown. Similar to Yellow-throated Woodpecker, but a white throat and much less yellow on face. Compared to Golden-green Woodpecker, breast is scaled (not barred), and eye is dark. Forages at middle to upper levels of the forest, often with mixed-species flocks. Typical call is a hoarse scream.

The white-throated woodpecker is about 19 to 20 cm (7.5 to 7.9 in) long and weighs about 69 g (2.4 oz). Males and females have the same plumage except on their heads. Males are red from forehead to hindneck and very widely on the malar (cheek); the latter has a wide yellow stripe above it.The female has red only on the nape but is otherwise the same as the male. Adults of both sexes have the eponymous white chin and throat. Their upperparts are bronze-green. Their flight feathers are mostly dark brown with pale cinnamon-rufous on the inner webs. Their tail is blackish with greenish edges on the feathers. Their upper breast is yellowish green; the feathers have pale centers and dark tips. The rest of their underparts are white with olive barring. Their shortish beak is blackish to gray, their iris dark brown to red-brown, and the legs dark olive to blackish. Juveniles are greener than adults and males have red only from the rear crown to the hindneck.
分类信息
The white-throated woodpecker was originally described as Picus leucolaemus. Since its inclusion in Piculus it has at times been considered conspecific with the rufous-winged woodpecker (P. simplex), the stripe-cheeked woodpecker (P. callopterus), and the Lita woodpecker (P. litae); the four may form a superspecies. It and just the Lita woodpecker have also been treated as conspecific. The white-throated woodpecker is monotypic.

Upcher's Warbler
Hippolais languida
A medium-sized, gray-brown warbler that looks very similar to other species. Note the rather stout bill and broad dark tail. Smaller and browner than Olive-tree Warbler and larger than Eastern Olivaceous Warbler. Wing panel is not as prominent as that of Olive-tree Warbler. Breeds on scrubby hillsides and river valleys; occasionally in flatter lowlands. During non-breeding season, found in a variety of wooded or brushy habitats. Sings from prominent perches—a repetitive, rapid mix of musical and scratchy phrases. Call is a harsh "chak."
Chestnut-bellied Imperial-Pigeon
Ducula brenchleyi
A large dark pigeon with a deep chestnut belly and undertail. Entirely dark above with a contrasting paler head. Chestnut underwing separates this species from any other similar pigeon. Rare. Prefers very mature undisturbed hill forest. Most common call is a deep, drawn-out “whu-ooooow.”
Black-crowned Tchagra
Tchagra senegalus
A gray-brown bushshrike with rufous wings, a bold pale eyebrow, and a diagnostic all-black crown; most races have a distinctive gray belly. Pairs occasionally join mixed-species flocks and skulk in a variety of scrub, tangled thickets, and open woodland, foraging for insects on the ground or in the lower levels of vegetation. The species sings a wonderful melodious up-and-down whistled “whee-cheee-chooo-cheeera” and a variety of other whistles and grating sounds.
