Species List
Since Wolf Hollow began in 1983, over 220 different species of wild animals have been treated at our Wildlife Rehabilitation Center. Some are species that we have treated only once or twice in all of our years of operation (e.g. Western Bluebird, Steller’s Sea Lion), while others are animals we see many of each year (e.g. American Robin, Cottontail Rabbit).
