Above: George V. Kollias, professor of wildlife medicine, right, prepares a river otter for a Nov. 8 release in the Otselic River. Part of a reintroduction effort by the New York River Otter Project, the animals are humanely trapped from areas where they are abundant, cared for at the College of Veterinary Medicine, then set free in regions where their numbers are depleted.
