Although it looks a lot like a house cat, this feline is actually an elusive Bolivian species called the oncilla. This photo, which just won BBC Wildlife’s camera-trap photo competition, was taken in Madidi National Park and was the first documentation of the cat’s presence here. Capturing it on film brings the park’s confirmed cat species to six.

Cute But Deadly: Cats are a Far Bigger Threat to U.S. Birds Than Windmills

By Patrick Morgan | March 21, 2011 2:18 pm

What’s the News: After tracking baby gray catbirds with miniature radio transmitters, biologists found that cats were by far the #1 bird killer: 47 percent of the birds died at the paws of pet and feral felines (out of 80 percent that were killed by predators in general). This echoes some biologists’ view that cats are a destructive, human-assisted invasive species: “Cats are way up there in terms of threats to birds — they are a formidable force in driving out native species,” said one of the authors of the study.

What’s the Context:

Not So Fast: While cats were the biggest threat to birds in this study, the lead author notes that the biggest culprit for bird deaths over all is still building collisions.
