Infection by Bunyamwera virus (BUNV) species (Family Bunyaviridae, Genus Orthobunyavirus) has been detected in ewes, goats, cows, horses and humans all the way through America. However, there are no evidences of such infection in birds. To detect BUNV (CbaAr-426) infection in free ranging birds, a serological survey was carried out in Córdoba city between 2004 and 2005. Birds of 13 families presented neutralizing antibodies against BUNV (CbaAr-426), showing an increase in the seroprevalence from 6.6% to 13.8% between 2004 and 2005, respectively. Seroconversion for BUNV (CbaAr-426) was detected in Rufus hornero (Furnarius rufus) in January-February of 2005. This is the first evidence of natural infection by BUNV (CbaAr-426) in free ranging birds. The seroconversion level demonstrated active circulation of BUNV (CbaAr 426) in Córdoba city.
