Blue-backed Manakin
Chiroxiphia pareola
Small bird of riverine and gallery forests in both forest and savanna regions; generally inconspicuous when not displaying. Adult male is distinctive with black body, sky-blue back, and red or yellow crown patch; both sexes have orange legs. Female is similar to White-bearded Manakin, but has somewhat slimmer shape and longer tail. Inhabits forest understory but may ascend to canopy, especially when displaying. Feeds on fruit like other manakins and may be seen at fruiting shrubs and trees. Often detected by loud, single call note; males produce a variety of bizarre sounds in coordinated group display.
识别特征
Like other manakins, the blue-backed manakin is a compact, brightly coloured forest bird, typically 13 cm long and weighing 19 g. The male is mainly black with a bright blue back, and pale orange legs. The crown is typically red, but yellow in C. pareola regina from the south-west Amazon.<p>The female has olive-green upperparts, and somewhat paler olive underparts. Young males are olive, but show a red cap and the start of a blue back as they mature.<p>The race endemic to Tobago, C. p. atlantica is larger and has more extensive red on the crown and blue on the back. It has been suggested that it represents a separate species, the Tobago manakin, but no major authorities recognize this today.<p>This species is similar to lance-tailed manakin, Chiroxiphia lanceolata, which breeds further north from northern Venezuela to Costa Rica, but the latter has elongated central tail feathers, and the male has a somewhat brighter blue back.

分布与栖息地
It is found in southern Colombia, eastern Venezuela, the Guyanas, northeast Brazil, the Amazon Basin in Brazil, Bolivia, Ecuador and Peru; and in Tobago. A disjunct population exists on the coastal strip of southeast Brazil, about 3000 km long. The blue-backed manakin is absent in the northwest Amazon Basin, a region from central Venezuela to the southern border of Colombia. This manakin is a fairly common bird of dry and moist deciduous forests, but not rainforest.

行为
The male blue-backed manakin has a fascinating breeding display, unusual in that it is a cooperative display rather than competitive. Two males perch next to each other on a bare stick and jump up and down alternately, giving a buzzing call. When a female approaches, the perched bird moves backwards under the jumping bird, so the two perform a vertical circling movement. Groups of up to eight birds may perform together, with a different stick for each pair of displaying males. The female builds a twig nest in a tree; two brown-mottled white eggs are laid, and incubated entirely by the female for about 20 days.<p>Apart from the buzzing display song, blue-backed manakin has a number of other calls, including a whee-whee-CHUP, sometimes given by two male in synchrony.<p>These manakins eat fruit and some insects.

Bar-winged Flycatcher-shrike
Hemipus picatus
A small passerine bird with black-and-white plumage. The head, upperparts, and tail are black. The sides of the neck and underparts are white. The wing shows a prominent white slash, and the outer tail feathers are white. The bill is black and the upper mandible is hooked at the tip. Usually found in mixed-species foraging flocks, feeding on insects in the mid-canopy by hawking prey in mid-air like flycatchers, hence the name. Inhabits a wide range of forested habitats. Song is a sweet-sounding series of bouncing notes: “tsilikee-tsilikee-tsilikee!”
Gould's Petrel
Pterodroma leucoptera
Small gray-and-white gadfly petrel. Note distinctive dark gray cap extending from the crown down the sides of the face, nape and neck to the wing, contrasting with white face. Upperwings dark gray with distinctive dark ‘M’ that extends across the wings. Underparts all white apart from a broad black band at the bend of the wing which extends towards the tip and diagonally back towards, but not reaching, the body. Two subspecies; breeds off of New South Wales and along the central mountain range of New Caledonia respectively. Migrates east and north across Pacific Ocean after breeding. Distinguished from other gadfly petrels by darker cap, and broader dark band on underwing. Can be seen feeding in association with other seabirds, tuna and dolphins.
Sind Sparrow
Passer pyrrhonotus
A small, strikingly patterned sparrow which is extremely similar to the House Sparrow.
