Arborophila ardens · 海南山鹧鸪
Introduction
A monotypic species in the family Phasianidae, endemic to Hainan Island, China. It inhabits primary evergreen forests and is assessed as a vulnerable species due to habitat loss.
Description
Length is 26–28 cm (10–11 in). Males weigh about 300 g (11 oz) and females about 237 g (8.4 oz). The head is blackish with a white patch on the ear coverts and a whitish supercilium. The crown and nape are dark brown with black mottles. Upperparts are olive-brown with black scales. The throat and neck-sides are blackish, featuring an orange collar around the lower neck. Underparts are grey with a buffish central belly. Wings are greyish-brown. The beak is black, eyes are brown, and legs are dull reddish. Females are smaller and less bright than males.
Distribution & Habitat
Endemic to Hainan Island, China, with unsubstantiated reports from Guangxi. Habitat includes primary broadleaved or mixed coniferous-broadleaved evergreen forests at elevations of 600–1,600 m (2,000–5,200 ft), as well as forests recovering from logging.
Behavior & Ecology
Observed as single birds, pairs, and coveys. Diet consists of snails and seeds. The call is a repeated two-note sequence, 'ju-gu ju-gu ju-gu', sometimes accompanied by quick single notes from a second bird.
Conservation
Assessed as a vulnerable species by the IUCN. The population is estimated at 2,500–9,999 mature birds and has likely declined rapidly due to habitat loss from timber and agriculture clearance, illegal hunting, and climate change. Decline may have slowed due to new population discoveries since 2002 and increased forest protection. Of the 660 km² (250 sq mi) of suitable habitat, 410 km² (160 sq mi) are within nature reserves including Hainan Bawangling National Nature Reserve, Jianfengling, Wuzhishan, Diaoluoshan Limushan, and Nanweiling. It is a nationally protected species in China.
