Black-tailed Nativehen
Tribonyx ventralis
Small waterhen with an erect black tail (no white edges) resembling that of a domestic chicken. Note pale green base to the bill with a yellow tip and a red spot, bright red-pink legs, and pale spots on flanks. Frequents locations around inland wetlands, and is usually seen on land rather than in the water. Can occur in large numbers. Hard to approach, and when disturbed runs away fast. Tends to be less vocal than other waterhen species.
识别特征
The black-tailed nativehen is a large dark bird, reaching about 38 cm in length and weighing around 400 g (0.88 lb). This species possesses an erect tail and is endowed almost entirely with brownish-grey and green feathers. Its long legs and lower jaw are a striking pink-orange colour, as well as its eyes which are more of a bright orange colour. This species is not excessively vocal, its main call is an alarm 'kak' sound. They become noticeable when they are seen in small flocks on the ground. Their erect tails and social behaviour are reminiscent of domestic hens.

Riverbank Warbler
Myiothlypis rivularis
Brownish warbler with a strong vireo-like head pattern. Note the strong white eyebrow offset by a gray crown that is bordered with black. Largely olive-green above and buff below. The northern subspecies lacks the black border to the crown and has cinnamon-buff underparts and eyebrow. Usually seen foraging on the forest floor next to streams and rivers. The song is an ascending series of very loud whistles.
Rufous-tailed Rock-Thrush
Monticola saxatilis
Distinctive, small, short-tailed thrush-like bird. Males are strikingly beautiful with bright blue-gray head, white back patch, and chestnut underparts. Females are reddish-brown and have a scaly appearance, with a tail pattern similar to males. Breeds on rocky mountain slopes and alpine meadows, usually above 1,500 m (5,000 ft). Usually shy but may be obvious when delivering its melodic Eurasian Blackbird-like song in flight.
Horsfield's Babbler
Malacocincla sepiaria
A small, dull babbler with a short tail. Brown with a gray head and pale underparts. Dark gray crown, faintly streaked breast, and brighter buffy wash on the flanks eliminate similar-looking Abbott’s Babbler. Similarly drab White-chested and Sooty-capped babblers have longer tails and bills. Found in lowland and foothill forests. Typical song is a sharp chip followed by a whistled note or two: “chi puh-weee!”; Javan birds add a longer, ascending whistle to the end.
