An unusual pleomorphic sarcoma in a hybrid mallard An unusual pleomorphic sarcoma in a hybrid mallard

An unusual pleomorphic sarcoma from a hybrid mallard (Anas platyrhynchos) is described. Rhabdomyosarcoma was considered in the original differential diagnoses but rejected due to lack of specific characteristics generally seen in these tumors. The histologic characteristics described are consistent with mammalian sarcomas recorded in the literature as malignant fibrous histiocytoma.

A solitary case of duck plague in a wild mallard A solitary case of duck plague in a wild mallard

Duck plague was diagnosed on the basis of pathology and virus isolation in a wild female mallard Anas platyrhynchos found dead near Saskatoon, Saskatchewan. Day-old Pekin ducklings and one of two adult mallards died with lesions typical of duck plague following inoculation of tissue from the wild bird. This is believed to be the only reported case of duck plague in a wild bird since a...

Industrial halide wastes cause acute mortality of snow geese in Oklahoma Industrial halide wastes cause acute mortality of snow geese in Oklahoma

An examination of 97 dead migratory waterfowl collected at an industrial facility showed that the birds had had severe gastric and intestinal hemorrhaging. Water samples taken at on-site waste lagoons contained 6,750 mg/L fluoride, 4,500 mg/L bromine and 1,500 mg/L boron. Brain and liver tissues contained high levels of fluoride, as compared with tissues of birds collected at a control...

Lead poisoning in Canada geese on Plum Island, Massachusetts (USA) Lead poisoning in Canada geese on Plum Island, Massachusetts (USA)

During December 1983 and early January 1984, about 200 Canada geese (Branta canadensis) died of lead poisoning at Parker River National Wildlife Refuge on Plum Island, Massachusetts. In an effort to determine the source of lead, 100 bottom samples were taken from a refuge impoundment where much of the mortality/morbidity occurred. An average of 157,150 pellets/ha was found with a range...

Ingestion of plastic debris by Laysan albatrosses and wedge-tailed shearwaters in the Hawaiian Islands Ingestion of plastic debris by Laysan albatrosses and wedge-tailed shearwaters in the Hawaiian Islands

Surveys of Laysan Albatross and Wedge-tailed Shearwaters on Midway and Oahu Island, Hawaii, identified a high proportion of birds with plastic in the upper gastrointestinal tract, representing hazards to the health of adult birds and their chicks. Fifty Laysan Albatross chicks were examined for plastic items lodged within the upper digestive tract. Forty-five (90%) contained plastic...
