In January 1996, a family of “Three Strikes” grizzly bears was captured outside Yellowstone National Park, and U.S. Fish and Wildlife bear management guidelines required that they be placed in a permanent home in a zoological facility within 24 hours or be dispatched. Woodland Zoo in Seattle, Washington, offered them a temporary home until a permanent one could be found, and Big Bear Alpine Zoo had the space and interest to acquire them. The Friends of the Big Bear Alpine Zoo then had six weeks to raise $55,000 to bring the grizzly bear family to Big Bear, and the effort succeeded mainly through the Adopt a Brick Program. Overall, the Friends raised $108,000 and also received donated goods, and the grizzly bear family—Tutu, Ayla, and Harley—arrived at their new home on May 10, 1996. Grizzly bears, a subspecies of the brown bear, once roamed much of western North America and the Great Plains, but habitat loss from logging, mining, and spreading human development has brought bears and humans into contact, while early European settlers hunted them out of much of their original range. Today, roads pose a dangerous threat because they cut across historic bear habitat and force bears moving between wilderness corridors to cross routes often heavily traveled by vehicles. Grizzly bears are well adapted to seasonal change, with high intelligence and an incredible sense of smell that helps them detect food from great distances; during warmer months they eat massive amounts of fruits, berries, nuts, leaves, insects, and a variety of animals to store enough fat for winter, and in fall they use their long claws and strong shoulders to dig dens for hibernation, which conserves energy during the lean winter months.
