About These Birds
Tristan Moorhen
Tristan Moorhen (Gallinula nesiotis) is an extinct flightless rail formerly endemic to Tristan da Cunha in the South Atlantic. Dark sooty-brown with reduced wings and stout legs. Related to Common Moorhen but island-adapted. Extirpated by introduced rats and cats by the 19th century. Known from subfossil remains and early expedition accounts.
Talaud Rail
塔劳秧鸡分布于印度尼西亚塔劳群岛，属岛屿特有种。体型中等，羽色棕褐。与近缘种相似，栖息于热带森林地带，生性隐秘。因分布范围极为局限，种群数量稀少，面临森林砍伐带来的威胁。
