10 endangered birds under review

The Pacific region of U.S. Fish & Wildlife Service will review the status of 10 birds -- among other species -- protected by the Endangered Species Act. Public comments are welcome until May 7 about the 71 species, which occur in Oregon, Hawaii, Northern Mariana Islands and Guam.

Periodic status reviews of all listed species are required by the ESA at least once every 5 years to determine whether a species’ classification as threatened or endangered is still appropriate. If the best scientific and commercial data produced since the time of listing are not consistent with the current classification of any species, the Service will recommend a change in the species’ federal classification. A species could be recommended for reclassification from endangered to threatened (downlisting), from threatened to endangered (uplisting), or for removal from the federal list of threatened and endangered species (delisting).

Information that is considered in a status review includes:
· Species biology, including but not limited to, population trends, distribution, abundance, demographics and genetics;
· Habitat conditions including, but not limited to, amount, distribution and suitability;
· Conservation measures that have been implemented that benefit the species;
· Threat status and trends; and
· Other new information, data or corrections including, but not limited to, taxonomic or nomenclatural changes, identification of erroneous information contained in the list, and improved analytical methods.
The avian species include:
· Bridled White-eye (Zosterops conspicillatus conspicillatus) in Guam
· Guam Rail (Rallus owstoni)
· Hawaiian Crow (Corvus hawaiiensis)
· Hawaiian Duck (Anas wyvilliana)
· Hawaiian Hawk (Buteo solitarius)
· Mariana Common Moorhen (Gallinula chloropus guami)
· Nightingale Reed Warbler (Old World warbler) (Acrocephalus luscinia)
· Oahu Elepaio (Chasiempis sandwichensis ibidis)
· Palila (honeycreeper) (Loxioides bailleui)
· Small Kauai Thrush (Myadestes palmeri)
