About These Birds
New Britain Bronzewing
比亚克岛地鸠是印度尼西亚比亚克岛的特有鸠鸽，极为罕见。体羽深棕，与近缘种相似但分布更为局限。栖息于低地热带雨林，以种子和小型无脊椎动物为食，主要在地面活动。因分布极窄，被列为易危物种。
Polynesian Ground Dove
Small ground dove, 20–23 cm, with grey and brown plumage, dark reddish flight feathers, and white-tipped tail. Native to French Polynesia; extinct on many islands but survives in remnant populations on Moorea, Mopelia, and a few other atolls. Critically Endangered due to introduced rats, cats, and habitat loss.
