New estimate suggests hunting felines take bigger bite than expected out of wildlife
Domestic cats kill many more wild birds in the United States than scientists thought, according to a new analysis. Cats may rank as the biggest immediate danger that living around people brings to wildlife, researchers say.
America’s cats, including housecats that adventure outdoors and feral cats, kill between 1.3 billion and 4.0 billion birds in a year, says Peter Marra of the Smithsonian Conservation Biology Institute in Washington, D.C., who led the team that performed the analysis. Previous estimates of bird kills have varied, he says, but “500 million is a number that has been thrown around a lot.”
