Corsican Finch
Carduelis corsicana
Endemic to the islands of Corsica and Sardinia where it occurs in open lowland scrub to montane dry scrub and open to semiopen coniferous forests. A small finch with a bright yellow face and breast and a brown streaky back. Males brighter than females. Song is a jumbled twitter and calls include various tittering and whistled calls; all fairly similar to Citril Finch calls, but ranges do not overlap.
识别特征
It has dark-streaked brown upperparts and brighter yellow underparts than the citril finch does.
分类信息
The first formal description of the Corsican finch was by the German zoologist Alexander Koenig in 1899 under the binomial name Citrinella corsicana. It was formerly regarded a subspecies of the citril finch, but it differs in morphology and vocalizations (Förschler & Kalko, 2007) as well as mtDNA sequence (Sangster, 2000, contra Pasquet & Thibault, 1997, Förschler et al. 2009) and they are now considered distinct species (Sangster et al., 2002, Förschler et al. 2009).

Eastern Cattle-Egret
Ardea coromanda
Small, compact white heron with relatively short yellow bill. More often seen in dry habitats than other egrets, but also frequent in rice paddies and shallow wetlands. In the breeding season, look for bright orange head and breast, as well as a brighter bill. Leg color varies from reddish or yellow during the breeding season to black during the nonbreeding season. Juveniles have dark bill. Always note relatively short, thick neck and short legs compared with other egrets. Often gathers in flocks, frequently following large animals and field machinery.

Rufous-backed Honeyeater
Ptiloprora guisei
A common, medium-sized honeyeater of montane forest in eastern New Guinea. Gray head and underparts, diffuse rufous-brown back and flanks, with whole body boldly patterned with dark streaks. Long curved bill, pale gray eye and a distinctive pale gray stripe running back from above the eye. Forages out in the open and readily observed. Similar to Gray-streaked but Rufous-backed usually occurs at lower elevation and has a rufous rather than gray back. Common call, a falling then rising “piuuwiiii!”.

Sumatran Green-Pigeon
Treron oxyurus
Relatively plain and unmarked green-pigeon with a long pointed tail. Males have a faint orange blush on the chest, though this can be hard to notice. Note blue-green bill and “goggles” in both sexes. Completely unmarked dark olive-green wings separate this species from other green-pigeons within its range; Wedge-tailed Green-Pigeon can be similar, but note that species’ much more thickset build and shorter tail. Endemic to the hill forests of Sumatra and western Java. Like other green-pigeons, gathers in fruiting trees. Gives rising and falling series of high-pitched coos, often with a hiccuping or sobbing quality.
