Date: Fri, 8 Aug 2003 From: Mary Ellen Clinton <metanager@yahoo.com> Hi. I was intrigued by the posting that brown headed cowbirds are the preferred food source for the mosquitoes that carry WNV. I would be interested to know how susceptible these birds are to the virus, how high their mortality is due to the disease? Since brown headed cowbirds are a major cause of the decline of warblers and other migratory songbirds in the eastern United States, might we hope for a slightly positive side effect of WNV in reducing the population of these nest parasites?
