Both the NWRA and IWRC are great places to get training and to network with others rehabilitator. If you are interested in becoming a rehabilitator, we strongly recommend the IWRC Basic Wildlife Rehabilitation class, joining the IWRC, and NWRA, attending a national symposia for either and subscribing to Wildlife Rehab today.
