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.
