West Nile virus (WNV), a Flavivirus, was introduced into New York City in 1999 (Centers for Disease Control 1999, Enserink 1999). In the past decade the virus has spread across the continental United States and southern Canada, resulting in large numbers of deaths among native bird species (Anderson et al. 1999, Calle et al. 2000). The U.S. Geological Survey (USGS) Patuxent Wildlife Research Center in Laurel, Maryland, is home to the world’s largest collection of cranes. These cranes are used for research and for reintroduction programs. As of 20 October 2016, this collection included 77 of the highly endangered whooping cranes (Grus americana) used for reintroduction programs in Wisconsin and Louisiana.
