Daurian Jackdaw
Coloeus dauuricus
Small stout crow; often seen in large flocks, sometimes with other crows. Adult’s white neck and belly are unique in the region. Immature birds have pale gray cheeks but are otherwise black overall. Favors open areas with scattered trees; also around human habitation, particularly in agricultural fields. Gives nasal yelps, yaps, and caws.
识别特征
At about 32 cm (13 in) in length, the Daurian jackdaw is about the same size as or slightly smaller than the western jackdaw, with the same proportions and identical habits. The principal difference lies in the plumage; many but not all adults have large areas of creamy white on the lower parts extending up around the neck as a broad collar. The head, throat, wings, and tail are glossy black and the ear coverts are grizzled grey. Darker adults and young birds resemble western jackdaws, though Daurian jackdaws have black irises, unlike the distinctive grey-white irises of the Eurasian jackdaw. The only other pied corvid species inhabiting the same region is the Chinese collared crow (Corvus torquatus), but as this is a much larger bird (about the same size or slightly larger than the carrion crow), confusion is unlikely to occur.

分布与栖息地
The Daurian jackdaw ranges from the southern part of eastern Siberia, south to Mongolia and throughout much of China. In the north of its range it migrates further south during the winter. It is a scarce winter visitor to Korea, a rare annual winter visitor to Japan, and a vagrant to Taiwan. There are a few records from Western Europe. It inhabits open woodland, river valleys, and open hills and mountains.

Black-thighed Grosbeak
Pheucticus tibialis
Large-billed bird with yellow head, body, and black back and wings. Look for massive triangular bill and obvious white patch on wing. Sexes similar. Found in open wooded areas like forest edges, second growth, and gardens. Usually seen singly or in pairs.

Exclamatory Paradise-Whydah
Vidua interjecta
A nest parasite that lays its eggs in the nests of pytilias. As with other whydahs, breeding males are spectacular and bizarre, whereas non-breeding males and females are drab and inconspicuous. Breeding males are mostly black, with a rufous collar and a long tail with an odd widened area at its base. Non-breeding males and females have a brownish back, pale underparts, and a reddish bill. Generally scarce and local in broadleaf woodland and lush savanna. Breeding male similar to other paradise-whydahs, but has a longer tail than Sahel Paradise-Whydah, a shorter and thicker-based tail than Togo Paradise-Whydah, and a slightly shorter tail and more rufous collar than Eastern Paradise-Whydah. Non-breeding male and female can be cautiously identified by their combination of a reddish bill, pinkish legs, and simple facial pattern. Not very vocal, but does imitate pytilia vocalizations.

Lineated Woodpecker
Dryocopus lineatus
Large ‘woody woodpecker’ of tropical forest in lowlands and foothills. Also ranges into semi-open areas with tall trees, mangroves, and other lightly wooded habitats. The tufted red crest and black face distinguish it from adult Pale-billed Woodpecker, which often occurs in the same areas. Also note that the white ‘braces’ on the back of Lineated are widely spaced, unlike Pale-billed. Laughing call suggests a flicker, and very unlike calls of Pale-billed.
