Task: Question Answering
Input (English): passage: The United States as a whole has up to 18,000 wolves, about two thirds of which are in Alaska. They are increasing in number in all their ranges. Usually, however, wolves in the United States are mostly seen during the winter months in northern Minnesota, northern Wisconsin, Michigan's Upper Peninsula, and portions of Washington, Idaho, northern Oregon, and Montana, as the majority of wolf populations migrate from Canada to the Northwestern states & some of the Midwestern and Great Lakes States during the winter months for the competition over eating bison, elk, white tailed deer and other large ungulates, disputed between other carnivores such as grizzly bear, cougar, and coyote. Wolf recovery has been so successful that the United States Fish & Wildlife Service removed the western gray wolf from the federal endangered species list on March 28, 2008. Due to the controversy over wolf shootings, a coalition of environmental groups sued the federal government to put the gray wolf back on the Endangered Species list. On July 18, 2008, a federal judge ruled in favor of renewed endangered species protection. Alaska has a stable population of 10,500-12,000 wolves, which are legally hunted from August to April ( in deer-rich areas ) as a big game species.
