In mid-October, a young male Costa’s hummingbird went north instead of south, landing in a backyard in Saskatoon, Saskatchewan. The birds are native to the southwestern US and western Mexico. Environment Canada chemist Geoff Koehler found that the bird was hatched around Yosemite National Park. So he became Yosemite Sam. The owners of the backyard called Living Sky Wildlife Rehabilitation, a Saskatoon charity that helps injured and orphaned animals mend until they can return to the wild. Yosemite Sam lives in a cage designed to feel like California and enjoys a specialized diet of fruit flies and a special protein drink. Shadick hopes to find a rehabilitation center in California that can release him back into the wild -- but he will need permits to get home.
