AUSTIN, Texas (AP) — The population of golden-cheeked warblers, among the most famed of endangered species in Central Texas, is higher than previously estimated, according to research by Texas A&M University scientists to be published later this summer.

The researchers calculate the rangewide population of male warblers in Texas at a shade over 263,000. Previous surveys counted roughly 9,000 to 54,000 birds. The work will be published in the Journal of Wildlife Management; it was posted on the journal’s website earlier this year.
