Full Text

The golden-cheeked warbler (Dendroica chrysoparia) was listed as federally endangered in 1990. In the “Scientific Evaluation for the 5-year Status Review of the Golden-cheeked Warbler”, we compiled, summarized, and evaluated available information on the warbler to provide a foundation for U.S. Fish and Wildlife Service’s (USFWS) assessment of the species’ status, the first such review since 1990. Information provided in the evaluation is current as of February 2010.

In addition to the species’ ecology, demography, and population estimates, the scientific evaluation provides analysis of 5 factors used by USFWS to determine a species’ listing status:
(A) the present or threatened destruction, modification, or curtailment of its habitat or range
(B) overutilization for commercial, recreational, scientific, or educational purposes
(C) disease or predation
(D) the inadequacy of existing regulatory mechanisms
(E) other natural or manmade factors affecting its continued existence
The evaluation, however, does not make recommendations as to the listing status of the species. The final review and recommendations regarding the species’ status is the responsibility of the USFWS.
