Cryopreservation of American kestrel semen with dimethylsulfoxide

Semen samples from 15 male American Kestrels (Falco sparverius) were frozen in dimethyl sulfoxide (DMSO). The semen was thawed 1-14 mo later and used to inseminate six females during three breeding seasons. Kestrels inseminated with thawed semen containing 4% DMSO produced only infertile eggs (N = 14). Kestrels inseminated with thawed semen containing 6%, 8%, or 10% DMSO produced fertile eggs (N =

Perinatal mortality in caribou from the Porcupine herd, Alaska

During the 1989 caribou (Rangifer tarandus) calving season on the Arctic National Wildlife Refuge, Alaska (USA), 61 calf carcasses were examined for cause of death and associated pathology. Dead calves were located by low-level aerial searches with two fixed-wing aircraft and a helicopter over high density calving areas between the Hulahula and Aichilik rivers. Primary diagnoses included emaciatio

Implanting radio transmitters in wintering canvasbacks

To conduct telemetry studies of wintering canvasbacks (Aythya valisineria) on Chesapeake Bay [Maryland, USA], we needed to devise a suitable method of radio transmitter attachment. We describe as aseptic, intraabdominal surgical technique, using the inhalation anesthetic isoflurane, to implant 20-g radio transmitters in free-ranging canvasbacks. We evaluated the technique over 3 winters (1987-89),

Chemical ions affect survival of avian cholera organisms in pondwater

Avian cholera (Pasteurella multocida) is a major disease of wild waterfowl, but its epizootiology remains little understood. Consequently, we examined whether chemical ions affected survival of avian cholera organisms in water collected from the Nebraska Rainwater Basin where avian cholera is enzootic. We tested the response of P. multocida to ammonium (NH4), calcium (Ca), magnesium (Mg), nitrate

Control of avian influenza: Philosophy and perspectives on behalf of migratory birds

Aquatic birds are considered the primary reservoir for influenza A viruses (Nettles et al., 1987). However, there is little concern about avian influenza among conservation agencies responsible for the welfare of those species. IN contrast, the poultry industry has great concern about avian influenza and view aquatic birds as a source for infection of poultry flocks. In some instances, differen
