Daurian Partridge
Perdix dauurica
A stout terrestrial bird of open areas with ample grassy or shrubby cover. Moves into agricultural fields in winter to forage on waste grain. Gray-brown overall, with large dark blotch on the belly and orange face and breast, much like similar Gray Partridge, its westerly counterpart. Usually found in medium-sized groups.
识别特征
It is a rotund bird measuring roughly 28–30 cm (11–12 in) long. In the fall, males weigh about 200–340 grams (7.1–12.0 oz) and 290–330 grams (10–12 oz) for females. Both sexes have a sandy-orange face and long feathers under the beak, forming a 'beard'. The rest of the head and underparts are pale slate-grey with a buff line on the chest and black belly patch. The female has a smaller belly patch and is slightly duller than the male. Their song sounds like a higher-pitched, sped-up version of the grey partridge's; a shrill, grating kieerr-ik!<p>There are multiple subspecies, differing mainly in the plumage becoming darker and more rufous further east.[citation needed]

分布与栖息地
This partridge breeds generally on open grassland or steppe including farmland across much of temperate East Asia from Kyrgyzstan and extending eastward to China and Mongolia. It is a non-migratory terrestrial species, which forms flocks outside the breeding season in Autumn and Winter. In parts of its range, it overlaps with the very similar and closely related grey partridge, with which it forms a superspecies. They inhabit open country, ideally with some adjacent bushes or open woodland.

行为
Daurian partridges forage and move most actively during morning/evening hours and rest at mid-day, depending on weather.<p>Females usually lay around the second to third week of May. The nest is lined with grasses and twigs on the ground under a bush or in tall grass, and the typical clutch size is somewhere around 13–20 olive-brown eggs. Chicks are a pale yellow-brown dappled with shades of dark brown and rufous.<p>This is a seed-eating species, but the chicks in particular consume insects as an essential protein supply. They are capable of flying short distances around 2 weeks of age. When disturbed, it springs upward with whirring wings in a rapid, explosive manner, then it flies off to nearby cover, all while sounding off an alarmed staccato hek-hek-hek!

Rufous-necked Snowfinch
Pyrgilauda ruficollis
Quite brightly-colored for a snowfinch. Pale sandy brown above and white below with an orange crescent on the back of the cheek. May be confused with Blanford’s Snowfinch, but look out for a pair of roughly equal-length black stripes on the face which form a right angle. Found on wide open steppe meadows, pastures, and near human settlements.
Roraiman Nightjar
Tepuiornis whitelyi
A medium-sized, dark nightjar of tepui highlands, difficult to identify by plumage alone. Cryptically patterned with dark brown and gray accented with buffy and whitish bars and spots. Male has a white band in the wing, which the female lacks. Uncommon, found in humid forest and edges, as well as humid scrub close to forested areas. Distinctive voice is a hoarse whistle “whoEEuuu”, given repeatedly. Larger than the similar Band-winged Nightjar, and smaller than Blackish Nightjar, but best identified by voice and habitat.
Black-chested Honeyeater
Lichmera notabilis
An unmistakable, strikingly patterned songbird with a downcurved bill. Olive above, with a conspicuous white throat bordered below by a necklace of dark streaks. Rest of underparts lemon-yellow. Inhabits forest, forest edge, gardens, and scrub, where typically encountered in small groups. Confined to the island of Wetar, where no similar birds occur. Song is a short, buzzing, two-note “tzer-tzer.”
