White-bearded Manakin
Manacus manacus
Fairly common and widespread through much of South America. Males are distinctive with white throat, sharply defined black cap, black back and wings, and grayish belly. Legs bright orange-red. Females are duller olive with paler belly. Note red legs to help separate from other female manakins. Like most manakins, quite plump with a rather short tail and bill. Males gather at display sites in the understory of forest, where they make loud snapping noises with their wings. Also listen for a descending “peew” call. Away from display sites, rather inconspicuous and usually encountered singly, often around a fruiting tree.
识别特征
Like other manakins, the white-bearded manakin is a compact, brightly coloured forest bird, typically 10.7 centimetres (4.2 in) long and weighing 16.5 grams (0.58 oz). The adult male has a black crown, upper back, wings and tail, and the plumage is otherwise white. He has orange legs.<p>The female and young males are olive-green and resemble female golden-headed manakins, but they have orange legs. The race endemic to Trinidad, M. m. trinitatis is larger than mainland birds, and the female has yellower underparts. Apart from the buzzing display song, the white-bearded manakin has a number of other calls, including a trilled musical peeerr.

分布与栖息地
In South America, two thirds of white-bearded manakin's range is in the combined Amazon Basin, the Guianas, and the Orinoco River drainage of Venezuela; also eastern Colombia. Three disjunct populations occur: Pacific coastal Ecuador, with southwestern Colombia; coastal and inland western Venezuela with northwestern Colombia; and the largest, southeastern Brazil, with inland regions bordering Paraguay in the south, and from Paraná state to coastal Pernambuco in the northeast.<p>Only one area of the Amazon Basin does not have the species, the 2200 km Purus River region in southwestern Amazonas state.

行为
These manakins eat fruit and some insects and spiders.<p>The male white-bearded manakin has a fascinating breeding display at a communal lek. Each male clears a patch of forest floor to bare earth, and perches on a bare stick. The display consists of rapid leaps between sticks and the ground, accompanied by a loud wing snap, the whirring of the wings, and a chee-poo call. Groups of up to 70 birds may perform together, the largest leks being in Trinidad. The female builds a shallow cup nest low in a tree; two brown-mottled white eggs are laid, and incubated entirely by the female for about 18–19 days, with a further 13–15 days to fledging. The young are fed mainly on regurgitated fruit with some insects.

Zebra Finch
Taeniopygia guttata
Small finch with bright orange bill and a distinctive black-and-white “moustache” mark. Adult male gray above, with barred grayish bib, rusty white-spotted flanks, and black-and-white tail pattern. Female smooth gray to buff on the chest and belly; juvenile similar but with a dark gray bill. Inhabits arid inland Australia, where often found in very large flocks.
Genovesa Ground-Finch
Geospiza acutirostris
A wedge-billed Galápagos finch found only on Genovesa Island. Formerly considered a subspecies of Sharp-beaked Ground-Finch, and likewise has a sharp, thin bill with nearly straight edges. Bill is black on breeding male and dull orange on female and nonbreeding male. The only other slender-billed finch on Genovesa is the very different Gray Warbler-Finch, which has a thinner bill, tan (not sooty-black) adult male plumage, and paler and less heavily streaked female plumage. Common and easy to see in arid scrub near the coast.
Bridled Honeyeater
Bolemoreus frenatus
Medium-sized sooty gray honeyeater. The bright yellow base of the bill is a really obvious feature in an otherwise fairly uniformly dark gray bird. Bridled Honeyeater is found in rainforest in the higher elevations of the Wet Tropics in northern Queensland.
