White-collared Manakin
Manacus candei
Chunky little bird of humid forest edge and second-growth thickets (especially with Heliconia plants) in tropical lowlands. Away from display areas, usually found in ones and twos perched quietly or feeding at fruiting trees and bushes from understory to canopy. Display often draws attention: loud clicks, buzzes, and whistles given by males low in understory. Unmistakable male often detected by low wing rattle in flight. Female greenish with yellow belly and orange legs.
识别特征
The white-collared manakin is, like its relatives, a compact short-tailed bird with a heavy hooked bill, orange legs and brightly coloured male plumage. It is typically 11 cm long and weighs 18.5 g.<p>The adult male has a black crown, wings and tail, and a black band across the midback. The rest of the head, neck, breast and upper back are white, the rump is olive-green, and the belly is bright yellow.<p>The male wings are heavily modified, with the five outer primaries very narrow for their outer half, and the inner primaries thickened and bowed. This feature is shared only by the male orange-collared and golden-collared manakins. The male's call is a rolled preew, and the wings are used to make a loud snap like a breaking twig, as with other manakins, and various rustling and whiffling noises produced by the modified wings.<p>The female and young males are olive-green with a yellow belly. They are very similar to female orange-collared manakin, but there is no range overlap.

分布与栖息地
The bird is named after Admiral Antoine Marie Ferdinand de Maussion de Candé, an explorer of South America.It occurs in the lowlands and foothills of the Caribbean slope up to 700 m, being replaced on the Pacific slopes of Costa Rica and Panama by the closely related orange-collared (M. aurantiacus) and golden-collared (M. vitellinus) manakins.<p>It hybridizes extensively with the golden-collared manakin in a limited area in Bocas del Toro Province, Panama. The hybrids, which show a lemon yellow collar in males, were at one time considered a distinct species, the almirante manakin (Manacus×cerritus) (Brumfield et al., 2001; McDonald et al., 2001).<p>This is a bird of thickets at the edges of moist forest, tall second growth and old cacao plantations.

行为
Like other manakins, this species has a fascinating breeding display at a communal lek. Each male clears a patch of forest floor up to 120 cm across to bare earth, and leaps to and fro between thin upright bare sticks, giving a loud wing snap. When a female is present males jump together, crossing each other above the bare display court. The throat feathers are also erected to form a beard. The female lays two brown-speckled white eggs in a shallow cup nest 1–3 m high in a horizontal tree fork. Nest-building, incubation for 18–21 days, and care of the young are undertaken by the female alone, since manakins do not form stable pairs.<p>The white-collared manakin feeds low in the trees on fruit and some insects, both plucked from the foliage in flight.

其他鸟类
White-throated Magpie-Jay
Cyanocorax formosus
Spectacular, large, and often conspicuous jay of tropical lowland forests, plantations, and semiopen areas with hedges and tall trees; prefers drier areas, but locally in rather humid situations. Usually in small groups and can be surprisingly inconspicuous if feeding quietly. At other times, unavoidably noisy and impossible to overlook. No similar species in range. Note crest, white face and throat, and long white-edged tail.
Brazza's Martin
Phedinopsis brazzae
A typical martin with brown upperparts and pale underparts strongly marked with dark streaks. Juvenile is rustier, with a paler chin and throat, and is less boldly streaked below. Resident and restricted to forest-fringed rivers between south Congo and central Angola, breeding in small groups in sandbanks. Despite being fairly common, the species’ vocalizations are unknown. No other martins within its range are streaked below.
Red-tailed Shrike
Lanius phoenicuroides
Small, plain shrike of dry, open areas with low shrubby cover. Gray-backed and white-bellied, with a black mask and a rusty tail and crown. Very similar to the closely related Isabelline Shrike, but look out for Red-tailed’s stronger white brow, reddish crown instead of a gray one, and cleaner underparts. Perches on exposed bushtops, posts, and wires, from which it primarily hunts for insects and arachnids. Like other closely related small shrikes, incorporates mimicry into songs and gives harsh, rasping calls.
