The autumn leaves are turning to rusty, earth colors, golden, and bright auburn at the Willowbrook Wildlife Center in Glen Ellyn, Illinois. Even the Great Horned Owl Tanka is ready for the fall after twenty years recovery of its broken wing as an in-patient at theWillowbrook Animal Hospital. Otis the Screech Owl is growing new autumn feathers for the season under the care of Heidi and the other veterinarians. Both owls are showing off special care given, after they have been found injured and transferred to the Willowbrook Wildlife Center for "wild species native to DuPage County that have permanent disabilities". Neither one of the owls, Tanka nor Otis, can fly again in the silent nocturnal flight accustomed to their species. After one hour of wildlife discovery at the Willowbrook Discovery Center, one is ready to explore at close range the other native species in residence outdoors walking along the Nature Trail during the fall season.
