	Social Crows In Tree Crows appear to be the victims of the disease - not the critical hosts. A good host would need to maintain an intense viremia for 20-100 days, increasing the likelihood that the virus will be passed on to others. However, crows are intensely social birds, a behavior which makes them readily susceptible to infection. [2/11/2009]
