Mortality in tundra swans Cygnus columbianus Mortality in tundra swans Cygnus columbianus

Our paper identifies and examines the significance of hunting and non-hunting mortality affecting the Eastern Population (EP) and Western Population (WP) (see Serie & Bartonek 1991a) of Tundra Swans. Sport hunting (Serie & Bartonek 1991b), native subsistence hunting (Copp 1989, Stewart & Bernier 1989), malicious shooting (McKelvey & MacNeill 1981), avian cholera (Friend et al. 1981...

Effects of resighting errors on capture-resight estimates for neck-banded Canada geese Effects of resighting errors on capture-resight estimates for neck-banded Canada geese

Biologists who study neck-banded Canada Geese (Branta canadensis) have used capture and resighting histories to estimate annual resighting rates, survival rates and the number of marked birds in the population. Resighting errors were associated with 9.4% (n = 155) of the birds from a sample of Canada Geese neckbanded in the Mississippi flyway, 1974-1987, and constituted 3.0% (n = 208) of...

Diseases of whooping cranes seen during annual migration of the Rocky Mountain flock Diseases of whooping cranes seen during annual migration of the Rocky Mountain flock

Diagnosis and treatment of ill whooping cranes of the Rocky Mountain flock was provided by a zoological facility. Cases of avian cholera, lead poisoning and avian tuberculosis were encountered. The zoo efforts were an adjunct to the U.S. Fish and Wildlife Service, Whooping Crane Recovery Plan.

Lead poisoning of a marbled godwit Lead poisoning of a marbled godwit

A thin adult female marbled godwit (Limosa fedoa) found dead at Benton Lake National Wildlife Refuge, Montana, was found to have 17 ingested lead shot in its gizzard. Its liver contained 51.7 ppm lead (wet weight). Based on these necropsy findings a diagnosis of lead poisoning was made.

Poisoning of Canada geese in Texas by parathion sprayed for control of Russian wheat aphid Poisoning of Canada geese in Texas by parathion sprayed for control of Russian wheat aphid

Approximately 200 Canada geese (Branta canadensis) died at a playa lake in the Texas Panhandle shortly after a winter wheat field in the basin adjacent to the lake was treated with parathion to control newly invading Russian wheat aphids (Diuraphis noxia). No evidence of infectious disease was diagnosed during necropsies of geese. Brain ChE activities were depressed up to 77% below...

Brain acetycholinesterase activity in botulism-intoxicated mallards Brain acetycholinesterase activity in botulism-intoxicated mallards

Brain acetylcholinesterase (AChE) activity in captive-reared mallards (Anas platyrhynchos) that died of botulism was compared with euthanized controls. AChE levels for both groups were within the range reported for normal mallards, and there was no significant difference in mean AChE activity between birds that ingested botulism toxin and died and those that did not.

Effects of lead shot ingestion on selected cells of the mallard immune system Effects of lead shot ingestion on selected cells of the mallard immune system

The immunologic effects of lead were measured in game-farm mallards (Anas platyrhynchos) that ingested lead shot while foraging naturally, mallards intubated with lead shot, and unexposed controls. Circulating white blood cells (WBC) declined significantly in male mallards exposed to lead by either natural ingestion or intubation, but not females. Spleen plaque-forming cell (SPFC) counts...
