Quarterly Mortality Reports |
Avian botulism
mortality in migratory water birds peaked during late summer and
early fall. Mortality confirmed or suspected to be due to botulism
was reported to the National Wildlife Health Center (NWHC) from
more than 50 sites in 15 states by wildlife personnel from both
federal and state agencies. The greatest number of botulism outbreaks
occurred in North Dakota and the greatest number of dead birds were
collected in that state.
Avian botulism
occurred at many sites in the Prairie Pothole area of North and
South Dakota where botulism outbreaks had not been reported for
several years. Avian botulism occurred for a second year in Illinois
at the Chautauqua NWR and the majority of the 2,600 dead birds collected
were green and blue-winged teal. In the other states a wide variety
of avian species were collected during outbreaks including 16 species
of waterfowl, five species of shorebirds, five species of wading
birds, grebes, coots, gulls and pelicans.
The highest
mortality occurred in the dabbling ducks such as mallards, green-winged
teal, blue-winged teal, northern pintail, northern shoveler, gadwall
and American wigeon. However, many birds could not be identified
to species because of decomposition. The total mortality reported
to NWHC from botulism outbreaks was about 98,000 birds.

USGS National Wildlife Health Center - Disease Investigations Branch Chief, at 608-270-2460 or

Branch Chief at 608-270-2420.
