Yellow-faced Siskin
Spinus yarrellii
Small finch with bright yellow plumage; males have a black cap. Found at forest edges, in caatinga vegetation, in second growth, and even in coffee plantations. Rare; heavily exploited for the illegal cage bird trade. The song is a complex series of warbling notes. In the more common Hooded Siskin, males have a black head and females have less yellow below and are less uniform green on the head.
识别特征
The Yellow-faced siskin is sexually dimorphic with the male having a black crown. Both sexes have a bright yellow body with an olive back and black and yellow wings; the legs are pink and the tail is black on top and white underneath. Like other birds in its genus, it has a cone-shaped bill adapted to hold and shell seeds. The amount of black on the males head can vary with the lores and ear coverts also being black on some birds. Its call is a complex and melodious warble much like the calls of other relatives like the Pine siskin and American goldfinch.
分类信息
The Yellow-faced siskin was described in 1839 by John James Audubon from an adult male specimen in poor condition that he received from another ornithologist. The type locality was incorrectly given as "Upper California" due to the skin originally being collected from a captive bird there. Audubon placed it in the genus Carduelis, it was later placed in the genus Spinus, which merged with Carduelis in 1976, before the genus Spinus was resurrected with the Yellow-faced siskin being placed in it. It's Phylogeny has been obtained by Antonio Arnaiz-Villena et al. There are no recognised subspecies.

分布与栖息地
The Yellow-faced siskin has a spotty distribution throughout Southeastern Brazil in the states of Ceará, Paraíba, Pernambuco, Piauí, and Bahia. There is also a disjunct population in northern Venezuela, though many authorities consider these to be escaped cage birds; However, specimens of this population were collected there in 1914.

Sula Dwarf-Kingfisher
Ceyx wallacii
A small kingfisher with an entirely orange bill, dark blue upperparts, a paler blue stripe down the upperside, a white throat, and orange underparts. Also note the orange-washed pale patch on the sides of neck and the orange forehead patch. Inhabits forest understory. Confined to the Sula islands. Overlaps with Blue-eared and Common Kingfishers, but note Sula’s smaller size, entirely orange bill, and darker blackish-blue upperpart coloration. Gives an extremely high-pitched, shrill “tseeeeip” call, as is typical of dwarf-kingfishers.
Plain-winged Woodcreeper
Dendrocincla turdina
Medium-sized woodcreeper with a short bill. Found in the lower to middle levels of humid forests where it moves restlessly. Rather uniform rufous-brown overall with a brighter tail and a buff throat. Often associated with army-ant swarms and sometimes follows mixed-species flocks, but can also be encountered alone. The northern subspecies lacks the buff throat and has more rufous in the wings and tail.The song is a long (~60 seconds) series of “tchip-tchip-tchip” notes.
