TUCSON, Ariz. (AP) -- Dozens of bighorn sheep have a new home in southern Arizona but how they'll adjust to it is an open question. The Arizona Game and Fish Department on Monday released 31 bighorns in Catalina State Park. More releases are planned in future years. The hope is that the animals captured in the Kofa Mountains northeast of Yuma will settle into a new life in the Santa Catalina Mountains near Tucson. Bighorns had roamed the Catalinas until the 1990s. It's not known for certain what caused that herd to die off.
