Chinese Grouse

The females have an average mass between 270–407 g (9.5–14.4 oz), and the males between 279–390 g (9.8–13.8 oz). The average body length is 327–384 mm (12.9–15.1 in) for females and 355–403 mm (14.0–15.9 in) for males, making it the smallest of the grouse species. Chinese grouse are mostly brown, with lots of white and black patterning on their bellies. The males have a black chin patch, while females do not. Chinese grouse look similar to hazel grouse (Tetrastes bonasia), with a few differences in plumage colouration and pattern. Voice: The Chinese grouse, like other grouse species, use vocalizations when defending their territory. Their vocalizations can be described as a "whirring, bi-syllabic flutter-jump". These vocalizations are much less complex than those of the North American ruffed grouse.
