Hunters in Wisconsin reported killing four wolves in the first 24 hours of the state's wolf hunt, the Associated Press reports. The Wisconsin Department of Natural Resources has set a statewide overall quota of 201 wolves.
On Monday, opening day of the season, two groups filed a 60-day notice of their intent to sue the U.S. Fish and Wildlife Service over the delisting of Great Lakes wolves.
The Milwaukee Journal Sentinel says the Humane Society of the United States and The Fund for Animals are asking officials in Wisconsin and Minnesota to postpone the season until the case can be decided. The Wisconsin DNR says the notice will not stop the hunt.
Minnesota's first organized wolf hunt is scheduled for Nov. 3. The Minnesota DNR has set a statewide quota of 400 wolves.
