Orange-necked Partridge

Arborophila davidi

Small, intricately patterned forest partridge, found only in a very small area of Vietnam and an even smaller patch of far eastern Cambodia. Somewhat similar in appearance to Bar-backed Partridge; look out for a white throat, thicker black line through the eye, and finer, less prominent white “scale” markings on the side. Orange tinge on the throat is weak and not always noticeable in the gloom of the dense hill forest understory. Gives an ascending series of pleasant whistles.

识别特征

The orange-necked partridge is about 27 cm (11 in) long and weighs about 241 g (8.5 oz). The forehead and crown are dusky, and the nape is mottled brown. A black band extends from the beak to the sides of the neck, and a whitish band extends from the eye to the neck-sides, becoming orange. There is also a black breast-band. The chin is pale buff, and the throat is rusty-orange. The breast is olive-brown, and the belly is greyish and whitish. The flanks have black and white scallops. The back and rump are olive-brown, with dark brown bars. The wing coverts have black and grey bands. The eyes are brown, the beak is black, and the legs are pinkish.

分布与栖息地

The orange-necked partridge is found in southern Vietnam and a small area in Mondulkiri, Cambodia. It lives in forest in hills at elevations of 120–600 m (390–1,970 ft), preferring bamboos. It also occurs in some disturbed habitats, including scrubs, bamboos and logged plantations. In Vietnam, it occurs in several national parks and state forest enterprises. All of the individuals recorded in a 2005 survey lived less than 2 km (1.2 mi) from water.

Gabela Akalat

Gabela Akalat

Sheppardia gabela

A rather small, demure understory denizen resembling a cross between a robin and a flycatcher. Mostly dull brownish-olive with a rusty rump and a paler throat and belly. Juvenile is more mottled. A local and endangered bird found singly and in pairs in thick undergrowth of primary and secondary forest, thickets, and coffee plantations, resident in a narrow range along the Angolan escarpment between 810 and 1300 meters of elevation. Sits for long periods, sallying to catch insect prey. Calls include a soft series of descending whistles. May be mistaken for a flycatcher, but its furtive nature and preference for thick understory are unique within its range. 

Golden-billed Saltator

Golden-billed Saltator

Saltator aurantiirostris

Scarce and local in the Andean foothills of extreme northern Chile, but widespread in much of southern South America. Favors brushy hedgerows and scrubby thickets, usually in villages and around agricultural terraces. Sexes look similar and bold face pattern is distinctive, in combination with big orange bill. Juvenile has a dusky bill and duller face pattern, but soon attains adult appearance. Loud bright song can draw attention, but often sings from a concealed perch.

Lord Howe Rail

Lord Howe Rail

Gallirallus sylvestris

A long-necked and short-tailed rail with a long decurved bill. Uniformly brownish red, sometimes with variable barring on underside and flanks. Flightless. Naturally occurs in subtropical forest, but now mostly restricted to highest mountains. No similar species occur in its range. Often heard giving an advertising “coo-eet” call, but also commonly a series of drumming “booomp” notes.
