If you find a sick or injured animal, you may decide to contact a wildlife rehabilitator. Wildlife rehabilitators are individuals, veterinarians, or organizations licensed by MassWildlife who volunteer to care for sick or injured wildlife. Many rehabilitators specialize in caring for certain types of wildlife, such as songbirds or small mammals. Rehabilitators don't charge for their services, but will often accept donations to help cover their costs. Wildlife rehabilitation permits are governed according to 321 CMR 2.13.
