Abstract

Eastern equine encephalitis virus (EEEV) infects many avian species but has rarely been described in Ruffed Grouse (Bonasa umbellus). Between September and December 2019, 40 Ruffed Grouse, most in poor physical condition, were submitted to the Michigan, Wisconsin, and Minnesota (US) Departments of Natural Resources; eight were positive for EEEV.
