The Saipan reed warbler or gå'ga' karisu in Chamorro (Acrocephalus hiwae) is a critically endangered songbird of the Northern Mariana Islands.
Taxonomy[edit]
It is sometimes considered a subspecies of the extinct nightingale reed warbler (A. luscinius) by some taxonomists.
Distribution and habitat[edit]
It occurs on two islands: Saipan and Alamagan. An estimated population of 2700 birds was reported in 2009 on Saipan, and on Alamagan 950 birds were reported in 2010.[1] It inhabits wetlands, thickets and the margins of forests.
Description[edit]
The Saipan reed warbler is approximately 17 cm (6.7 in) long, and is greyish olive-brown above with a pale-yellow underside. The female is slightly smaller than the male. Both sexes have a long bill compared to other reed warbler species.
Conservation[edit]
Threats to the survival of the Saipan reed warbler include habitat destruction resulting from urban development and agriculture, the introduction of invasive species, and volcanic eruptions.[2]
