Eastern equine encephalitis virus (EEEV) is a mosquito-borne pathogen that cycles in birds but also causes severe disease in humans and horses. We examined patterns of avian host use by vectors of EEEV in Alabama from 2001 to 2009 using blood-meal analysis of field-collected mosquitoes and avian abundance surveys. The northern cardinal () was the only preferred host (fed on significantly more than expected based on abundance) of , the enzootic vector of EEEV. Preferred hosts of , a putative bridge vector of EEEV, were American robin (), Carolina chickadee (), barred owl (), and northern mockingbird (). Our results provide insight into the relationships between vectors of EEEV and their avian hosts in the Southeast and suggest that the northern cardinal may be important in the ecology of EEEV in this region.
