Some bird species in Georgia are declining, the victims of invasive species and habitat loss. The birds here have lots of company. A recently released report, "State of the Birds," estimates that nearly one-third of America's 800 bird species aren't thriving. How birds fare is an indicator of how healthy our environment is, Interior Secretary Ken Salazar said. "[B]irds today are a bellwether of the health of land, water and ecosystems," he said in a prepared statement. More than a dozen federal and private, nonprofit agencies, including the Audubon Society, U.S. Fish and Wildlife Service and the Nature Conservancy, participated in the report, a 36-page compendium of facts and photos. Conservation ecologist Malcolm Hodges, who works for the Georgia branch of the Nature Conservancy, cited eight species indigenous to Georgia and the Southeast highlighted in the report. One, the laughing gull, is considered thriving.
