At least two male and two female adult wolves were shot dead in the first 24 hours of Wisconsin's first wolf hunt in decades. The controversial hunt is scheduled to run through February, but the state might end it sooner if hunters hit the limit of 116 wolves. Some 1660 hunters won licenses in a lottery to participate in the hunt. As many as 850 wolves roam the state, and farmers have long complained about wolf attacks on livestock. But animal advocates say the wolf population, only recently taken off the federal endangered list, is too fragile for a hunt. The Humane Society is moving in court to block the shootings, reports CBS.
