 WASHINGTON (AP) - Birds that once flourished in suburban skies, including robins, bluebirds and crows, have been devastated by West Nile virus, a study found.
Populations of seven species have had dramatic declines across the continent since West Nile emerged in the United States in 1999, according to a first-of-its-kind study. The research, to be published Thursday by the journal Nature, compared 26 years of bird breeding surveys to quantify what had been known anecdotally.
"We're seeing a serious impact," said study co-author Marm Kilpatrick, a senior research scientist at the Consortium of Conservation Medicine in New York.
