RESUMO
Cloacal swabs collected from wild bald eagle nestlings (Haliaeetus leucocephalus) were tested for viruses. A virus isolated from one of these samples had a lipid coat and contained DNA. Electron microscopy confirmed that it was a herpesvirus. This appears to be the first report of a herpesvirus isolation from a wild bald eagle.

A herpesvirus was isolated from captive cranes involved in a 1978 die-off. Neutralizing antibody to this virus was detected in this captive population as early as 1975 and consistently thereafter through 1979. Exposure to the virus evidently occurred at least 2 1/2 years before the die-off, without causing any mortality diagnosed as being caused by inclusion body disease of cranes (IBDC). Overcrowding and environmental conditions in 1978 may have contributed to the deaths of certain species of cranes in one area and not in another. Mortality ratios and serological data suggest that crane species vary in their response to IBDC virus.
