Geographic Range [top]

Range Description: Zapornia monasa was endemic to Kosrae, Caroline Islands, Federated States of Micronesia. Kittlitz collected the only two known specimens (now in St Petersburg) in 1827-1828, and regarded the species as uncommon even then (Taylor 1998). It declined to extinction over the next half-century.

Habitat and Ecology [top]

Habitat and Ecology: It inhabited coastal swamps and marshes, taro patches and "continually wet, shadowy places in the forest" (Taylor 1998). Measurements of the carpometacarpii from x-rays of the two specimens suggest that the species was flightless (Steadman 1986).

Systems: Terrestrial; Freshwater; Marine

Threats [top]

Major Threat(s): Its extinction quickly followed the arrival of rats from missionary and whaling ships in the 1830s and 1840s (Taylor 1998).
