Bay-chested Warbling Finch
Castanozoster thoracicus
Small finch with a conspicuous chestnut breast and flanks. Gray above with a white throat and belly and a white arc below the eye. Found at the edge of montane forests, in open woodlands, and clearings; often accompanies mixed-species flocks. Listen for its calm “tsip-cheep” song.
识别特征
The bay-chested warbling finch (Castanozoster thoracicus) is a species of bird in the family Thraupidae. It is endemic to southeastern Brazil. Its natural habitats are temperate forests and subtropical or tropical moist montane forests.
分类信息
The bay-chested warbling finch was formally described in 1835 by the Finnish naturalist Alexander von Nordmann from a specimen collected in Brazil. He coined the binomial name Frigilla thoracica. This species was traditionally placed in the genus Poospiza. A molecular phylogenetic study published in 2014 found that the genus was polyphyletic. In the subsequent reorganisation the bay-chested warbling finch was moved to its own newly erected genus Castanozoster. The name combines the Ancient Greek καστανό meaning "chestnut" with ζωστήρ meaning "belt". The bay-chested warbling finch is monotypic: no subspecies are recognised.

Long-billed Murrelet
Brachyramphus perdix
Small, chunky seabird of the northwestern Pacific, usually seen at sea, sometimes near land. Breeding adult is chocolate brown with scaled brown-and-white underparts. Wintering adult is gray above and white below with thin white “spectacles” and patchy white splotches on the sides and back. Nonbreeding Spectacled Guillemot perhaps similar but is significantly larger, with much neater black-and-white plumage (and more extensive white on neck), more prominent forehead, and much longer bill.

African Pitta
Pitta angolensis
An unusual and beautiful bird that is rarely seen, even by those expressly looking for it. Note the buffy underparts, green back, red undertail, and bold facial pattern. Found on the floor of forest and dense thicket. Very shy, remaining motionless for long periods. At least some populations are migratory within Africa. The call is an explosive, liquid “phwit.” Can only be confused with Green-breasted Pitta, but separated by the lack of a dark-green breast.

Russet-winged Spadebill
Platyrinchus leucoryphus
Small flycatcher with a broad flat bill, although the bill shape can be difficult to see. A rare inhabitant of the undergrowth of humid forests and old second growth. Note the white spot on an olive-brown crown, a prominent buff eyebrow, and pale ear patch. The back is olive-brown in contrast to the cinnamon wings, white throat, and buff belly. The call is a very sharp whistled “tchew-tchew.”
