Retrospective study of the diagnostic criteria in a lead-poisoning survey of waterfowl Retrospective study of the diagnostic criteria in a lead-poisoning survey of waterfowl

Between 1983 and 1986 the National Wildlife Health Center (NWHC) conducted a nationwide study of lead poisoning of waterfowl from federal and state refuges. This survey was done to assist in identifying zones with lead-poisoning problems. One thousand forty one moribund or dead waterfowl were collected and examined. The presence or absence of 13 gross lesions selected as indicators of...

Leucocytozoon simondi in Emperor Geese from the Yukon-Kuskokwim Delta in Alaska Leucocytozoon simondi in Emperor Geese from the Yukon-Kuskokwim Delta in Alaska

We surveyed Emperor Geese (Chen canagica) in western Alaska for avian hematozoa. Blood smears were collected from 134 adults and goslings in late July 1996, on their breeding grounds on the Yukon-Kuskokwim Delta. One of 134 (0.7%) Emperor Geese harbored Leucocytozoon simondi, representing a new host record for this parasite. No other hematozoa were detected. This is one of few reports of...

Evaluation of two oral baiting systems for wild rodents Evaluation of two oral baiting systems for wild rodents

Tetracycline hydrochloride (TC)-treated peanut butter or rodent chow baits were distributed during March 1990, on separate 0.53 ha sites in Oglethorpe County, Georgia (USA). Rodents were trapped on a control site prior to bait distribution and on two baited sites 6 days post-distribution. Cleaned skulls from euthanized mammals were grossly examined for TC florescence using an ultraviolet...

An epizootic of common loons in coastal waters of North Carolina: Concentrations of elemental contaminants and results of necropsies An epizootic of common loons in coastal waters of North Carolina: Concentrations of elemental contaminants and results of necropsies

A 1993 die-off of common loons (Gavia immer) in the coastal waters of North Carolina was investigated with emphasis on comparing mercury, selenium, arsenic, and lead between birds from the epizootic and reference specimens. Die-off specimens were emaciated but contained no ingested foreign bodies and no lesions suggestive of infectious disease. Results of bacteriology, virology...

Helminth parasites of the bald eagle, Haliaeetus leucocephalus, in Florida Helminth parasites of the bald eagle, Haliaeetus leucocephalus, in Florida

Twenty species of helminths (9 trematodes, 9 nematodes, and 2 acanthocephalans), including 9 new host records, were collected from 40 bald eagles (Haliaeetus leucocephalus) from Florida. Intensities of infection were low and no lesions were attributed to the parasites. No species were considered specialists in bald eagles; 5 species were considered raptor generalists and the remainder...
