Cats Responsible for Decline in Bird Species - as part of the news series by GeoBeats. Research into house cat behavior shows that they kill more animals than previously believed. University of Georgia researchers attached cameras to 60 cats in the Athens, Georgia area and will be exhibiting their results at an Ecological Society of America conference in Portland, Oregon. Although about 30 percent of outdoor cats hunt and kill prey, "cat predation is one of the reasons why one in three American birds species are in decline," says George Fenwick, president of American Bird Conservancy. In a study released last year, University of Nebraska researchers found “that feral cats were responsible for the extinction of 33 species of birds worldwide.” Cats are predators of many animals besides birds and mice. Snakes, lizards, frogs, chipmunks, voles and worms are also on the menu. The researchers studied the captured footage of the cat subjects, who spent an average of four to six hours outside everyday. Working with National Geographic CritterCam’s smallest camera, the researchers also caught cats in some dangerous situations like crossing the road and exploring drain pipes.
