Although it would seem logical that large numbers of roosting birds would attract more mosquitoes that carry West Nile virus and contract the disease when bitten, recent research has found the opposite to be true. That is, when large groups of birds roost together the chances that an individual bird will get bitten by mosquitoes carrying West Nile virus and subsequently contract the disease actually go down.
