Quarterly Mortality Reports |
West Nile Virus. West Nile virus
(WNV) dead bird surveillance is underway. USGS National Wildlife
Health Center (NWHC) is continuing to provide WNV testing for several
states. NWHC is primarily focusing on testing birds in the Corvidae
family (crows, jays and magpies), and raptors. This is due to the
high prevalence of WNV in these species in previous years.
The first positive
case this year was reported by New Jersey and involved a crow collected
in Bergen County, NJ on 30 April 2001. Through the end of June 2001,
US states that have had birds/mammals test positive for WNV are
CT, FL, GA, MD, NJ, NY and RI. Florida and Georgia are new locations
for confirmed WNV cases. Current maps showing states that are participating
in WNV surveillance and locations for positive WNV cases can be
found on the Center for Integration of Natural Disaster Information
(CINDI) website at http://cindi.usgs.gov/hazard/event/west_nile/west_nile.html#2001.
Please also go to the Centers for Disease Control and Prevention
(CDC) website at http://www.cdc.gov/ncidod/dvbid/westnile/index.htm
for up-to-date information on WNV. For information on how to submit
a bird for WNV testing in your state, please contact your local
public health department or visit our website at
http://www.nwhc.usgs.gov/disease_information/west_nile_virus/index.jsp.
If you are unable to find the information you need, please call
Kathryn Converse or Kimberli Miller at (608) 270-2400 for directions
on how and where to submit a dead bird for WNV testing.
Amphibian
Morbidity and Mortality. From late April
to early June, there were 10 reports of morbidity and mortality
in immature and adult amphibians. Mortality sites in six states
ranged from vernal pools, seasonal and permanent ponds, kettle ponds,
stock ponds to impoundments and affected a range of species of terrestrial
and tree frogs, toads, newts and salamanders. Causes of illness
or death varied as well and included suspect and confirmed iridovirus,
chytrid fungus and yeast-like infections, trauma and parasitism.
California
Least Terns. In mid-June
2001, the U. S. Fish and Wildlife Service, Carlsbad California Field
Office, reported the mortality of endangered California least tern
chicks in several nesting colonies along the southern California
coast. By late June, the mortality had increased to nearly 400 chicks.
Tern biologists suggest the chick mortality could be due to infectious
disease, predation, starvation due to food scarcity, disturbance
by predators, or intoxication by naturally occurring marine biotoxins.
The only significant finding in two chicks submitted to the NWHC
was emaciation. An investigation of this event is ongoing and additional
submissions are anticipated.
Avian Botulism
at Sonny Bono Salton Sea NWR. Avian botulism
type C was confirmed at Sonny Bono Salton Sea NWR in a herring gull
collected 15 May 2001, and a brown pelican on 07 June 2001. To date,
31 dead birds have been collected. Twenty-four (80%) were pelicans
with 21 (67%) endangered California brown pelicans. In addition
to the pelican mortalities, 60 sick brown and 3 sick American white
pelicans were retrieved and placed in rehabilitation. An estimated
3,895 pelicans were at risk during this quarter. During June, there
were concurrent fish mortalities that included over 2.2 million
tilapia, croaker and orange-mouth corvina.
Diazinon
in Atlantic Brant. New Jersey Department
of Fish & Wildlife reported a mortality event involving approximately
85 Atlantic brant. The event occurred 30 April 2001 - 5 May 2001,
at the southern tip of New Jersey in Cape May County. Upon toxicological
analysis, Diazinon, an organophosphate pesticide, was detected.
The source of the poison is unknown. Nearby Cape May NWR was unaffected
by the event and did not report any dead birds. The New York Wildlife
Pathology Unit has documented at least 3 brant die-offs in New York
due to diazinon from the late 1970's to mid 1990's.
For additional information please contact Dr. Scott Wright,
USGS National Wildlife Health Center - Disease Investigations Branch Chief, at 608-270-2460 or
Paul Slota, USGS National Wildlife Health Center - Support Services
Branch Chief at 608-270-2420.
