EX
Kosrae Crake Zapornia monasa



Justification

Justification of Red List Category
This species was known from the island of Kosrae in Micronesia. The only records come from 1827-1828 and it is thought to have been driven Extinct by introduced predators in the subsequent 50 years.

Population justification
None remain.

Distribution and population

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.

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).

Threats

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