Lita Woodpecker
Piculus litae
Scarce, yellow-faced woodpecker of lowland and foothill rainforest in western Colombia and northwestern Ecuador. Both sexes have olive upperparts, strongly barred or scaled underparts, and red wing patch. Male has red crown and mustache stripe; female has little or no red on head. No overlap with the similar White-throated Woodpecker. Forages at middle to upper levels of the forest, sometimes with mixed-species flocks. Call is a harsh scream.
识别特征
The Lita woodpecker is about 17 to 18 cm (6.7 to 7.1 in) long. 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 rest of the face is golden-yellow. The female has red only on the nape and malar but is otherwise the same as the male. Adults of both sexes have a dusky olive chin and throat that appear blackish at a distance. Their upperparts are olive-yellow to bronze-green with a slightly darker rump. Their flight feathers are mostly dark brown with olive on the outer webs, pale cinnamon-rufous on the inner webs, and black tips. Their tail is blackish with greenish edges on the feathers. Their underparts are whitish with black wedge-shaped bars. Their shortish beak is light bluish with a black tip, their iris dark brown, and the legs dark slate blue. Juveniles are duller and greener than adults, have red only on the nape, and have a streaked throat.
分类信息
The Lita woodpecker was originally described as Chloronerpes litae. 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 white-throated woodpecker (P. leucolaemus); the four may form a superspecies. It and just the white-throated woodpecker have also been treated as conspecific. The Lita woodpecker is monotypic.

行为
As far as is known, the Lita woodpecker is a year-round resident throughout its range.<p>The Lita woodpecker forages from the forest's middle levels to the sub-canopy, usually by itself and sometimes in pairs. Its diet has not been studied but is assumed to be adult and larval insects.<p>Almost nothing is known about the Lita woodpecker's breeding biology. Excavation of and attendance at apparent nest holes have been observed in July and August.<p>The Lita woodpecker makes "[h]issing 'shreeyr' or 'peessh'" calls that are very similar to those of other Piculus woodpeckers.

Black Laughingthrush
Melanocichla lugubris
The otherwise solidly dark plumage of this laughingthrush is punctuated by a patch of bare bluish-gray skin behind the eye and a bright orange-red bill. Favors the lower levels of foothill and submontane broadleaved forests; often in pairs or small flocks, sometimes mixed in with other species. Gives loud high-pitched bubbling clucks, often in prolonged series.
Brown-throated Wattle-eye
Platysteira cyanea
Small black-and-white bird with a bright red patch of bare skin above the eye. Males have a black breast band, and females a brown throat. Found in thick woodland, gallery forest, and mangroves. The song is usually given as a duet: a descending series of melancholy whistles from the male, and lower rasping notes from the female. Similar to Black-throated Wattle-eye, but shows a white slash on the wing, and the female has a brown rather than white throat. Separated from batises by the red wattle and, in females, by the brown throat.
Uluguru Bushshrike
Malaconotus alius
A large, unusual bushshrike of Tanzania’s Uluguru Mountains with a huge bill, a black head, a green back, and yellow underparts. Found in the canopy of montane forest, usually in pairs. Most often detected by the distinctive and unusual voice, which consists of sliding whistles given in pairs, one lower and one higher, along with well-spaced ratcheting notes. These two vocalizations are usually synchronized as a duet by a pair.
