Sitka, a Bald Eagle and Raptor-in-Residence here at the Alaska Raptor Center, showing off her preening skills! Preening is a bird's way of grooming its feathers to keep them in the best condition. While preening, birds remove dust, dirt, and parasites from their feathers and align each feather into the perfect position! Most birds will preen several times a day to keep themselves healthy. | Alaska Raptor Center
