I observed this American Crow in a pasture near the intersection of Rosemeade and Marsh. The crow appeared to be eating a sandwich, which was probably pilfered from the trash of a nearby convenience store.
Wikipedia has this to say about American Crows:
American Crows are common, widespread and adaptable, but they are highly susceptible to the West Nile Virus. They are monitored as a bioindicator. Direct transmission of the virus from American Crows to humans is not recorded to date, and in any case not considered likely.
