The selection of vertebrate hosts by mosquitoes relative to West Nile virus (WNV) transmission in neotropical countries such as Guatemala is not described. This study determined the feeding patterns of and and estimated the relative contribution of two common and frequently infected wild bird species, and , to WNV transmission. Engorged mosquitoes were collected from rural and urban habitats after the dry and wet seasons in the Department of Izabal in 2007. Host selection by varied significantly between urban and rural habitats. Both and fed predominantly on chickens and other domestic animals. Blood meals from wild birds were rare, accounting for 1.1% of blood meals identified from and 6.5% of blood meals from . Transmission of WNV by these two mosquito species may be dampened by extensive feeding on reservoir-incompetent hosts.
