Little Bustard
Tetrax tetrax
A small brownish bustard with long legs and neck. May crouch if disturbed but when flushed, explodes noisily into a grouselike flight with whirring wings. Striking white wings with black tips are prominent in flight. Breeding-plumaged males are distinctive with black neck and double V-shaped white collar. Usually fairly quiet and unobtrusive. Found in open plains with shrubs and sufficient ground cover to hide in.
识别特征
Although the smallest Palearctic bustard, the little bustard is still pheasant-sized at 42–45 cm (17–18 in) long with a 90–110 cm (35–43 in) wingspan and a weight of 830 g (29 oz). In flight, the long wings are extensively white. The breeding male is brown above and white below, with a grey head and a black neck bordered above and below by white.<p>The female and non-breeding male lack the dramatic neck pattern, and the female is marked darker below than the male. Immature bustards resemble females. Both sexes are usually silent, although the male has a distinctive "raspberry-blowing" call: prrt.

分布与栖息地
It breeds in Southern Europe and in Western and Central Asia. Southernmost European birds are mainly resident, but other populations migrate further south in winter. The central European population once breeding in the grassland of Hungary became extinct several decades ago. The species is declining due to habitat loss throughout its range. It used to breed more widely, for example ranging north to Poland occasionally. It is only a very rare vagrant to Great Britain despite breeding in France.On 20 December 2013, the Cypriot newspapers 'Fileleftheros' and 'Politis', as well as news website 'SigmaLive', reported the discovery of a dead little bustard in the United Nations Buffer Zone. The bird had been shot by poachers hunting illegally in the zone. The shooting was particularly controversial amongst conservationists and birders since the little bustard is a very rare visitor to Cyprus and had not been officially recorded in Cyprus since December 1979. The bird's habitat is open grassland and undisturbed cultivation, with plants tall enough for cover. Males and females do not differ markedly in habitat selection. It has a stately slow walk, and tends to run when disturbed rather than fly. It is gregarious, especially in winter.<p>Tracking of male Little Bustards has revealed that they are nocturnal migrants that make frequent stopovers in non-irrigated and irrigated croplands to reach more productive agricultural post-breeding areas.

Blue-black Grosbeak
Cyanoloxia cyanoides
Chunky, stout-billed bird of humid evergreen forest and edge in tropical lowlands. Usually found in pairs, often skulking at low to middle levels in lush vegetation. In typical views, looks simply dark. Note the large size relative to buntings, very stout bill, and broad tail, which can be twitched side to side. Male is deep blue-black overall. Female is rich dark brown overall. Sharp squeaky call often doubled and rather distinctive.
White-cheeked Partridge
Arborophila atrogularis
Appropriately-named; a gray-brown partridge with a bright white cheek patch. Like most other Arbrophila partridges, shy and seldom seen out in the open, usually moving about furtively under thick cover; sometimes crosses trails and openings, especially at dawn and dusk. Usually found in foothill habitats, including pristine primary forest, second growth, and even tea plantations. Song, usually heard late or early in the day, is a series of paired whistles.
Gray-sided Scimitar-Babbler
Erythrogenys swinhoei
A large scimitar-babbler found in the upper regions of hilly and montane forest. Upper body is uniformly warm orange-brown, and underparts are white with a light spattering of black streaks and spots on the throat and chest. Though shy and skulky, this species often gives away its position in thick scrub with a soft, hooting, two-note call.
