Pileated Finch
Coryphospingus pileatus
A distinctive gray finchlike bird found at forest edges and in light woodlands and scrub. Males are mostly gray with a white throat and a black crown with a red center, which can be erected when the bird is excited. Females are brown above and paler below with weak streaks on the breast.
识别特征
The grey pileated finch grows to a length of around 13 cm (5.1 in). The male has a white eye ring and a small patch of scarlet on the top of the head which can be raised as a crest, and this is partially concealed by the black plumage on the rest of the crown. The upper parts of the body, wings and tail are grey while the underparts are whitish, grading to grey on the flanks and breast. The female has a similar colouring but lacks the red and black on the head.
分类信息
This species was first described by the German naturalist Prince Maximilian of Wied-Neuwied in 1821. Molecular analysis has shown that C. pileatus and the red pileated finch (C. cucullatus) belong in the tanager family, Thraupidae, and form a sister group to a group containing the fulvous-crested tanager, the black-goggled tanager, the shrike tanagers and the grey-headed tanager. There are three recognised subspecies; C. p. brevicaudus from northern Colombia and northern Venezuela; C. p. rostratus from the upper Magdalena River Valley, Colombia; and C. p. pileatus from central and eastern Brazil.

行为
The grey pileated finch forages in small flocks, mostly on the ground but also in low undergrowth. Its diet is unknown. Breeding takes place in the wet season, this being some time between April and November in northern Venezuaella, and the exact timing depends on the onset of the rains.

Gray-hooded Gull
Chroicocephalus cirrocephalus
Distinctive gull. Breeding adults have a gray hood, pale eyes, and a red bill and legs. The back is medium gray and the wings have extensively dark flight feathers.

Striated Caracara
Daptrius australis
Fairly common locally on the Falklands and on remote and largely inaccessible islands south and west of Tierra del Fuego. Habits much like other caracaras; walks with agility to scavenge for food, and sails, soars, and tumbles easily on updrafts. Plumage dark overall, but with whitish wing panels visible in flight. Adult has fine silvery streaking (striations) on neck and breast, a yellow face, and a pale bill; immature is browner with duller streaking and a dark bill.
Blue-winged Warbler
Vermivora cyanoptera
Small, yellow warbler found in scrubby or cut-over habitats with some large trees, including field edges or powerline cuts. Yellow overall with black line through eye. Blue-gray wings with two whitish wingbars; sharply pointed bill. Adult males brighter than females and immatures. Two-note buzzy song sounds rather insect-like. Winters in Central America. Hybridizes with Golden-winged Warbler.
