Naturally occurring and experimentally induced castor bean (Ricinus communis) poisoning in ducks

Castor bean (Ricinus communis) poisoning accounted for the death of several thousand ducks in the Texas panhandle in the fall and winter months of 1969-1971.Signs of intoxication resembled those of botulism, except for mucoid, blood-tinged excreta. The most common lesions were severe fatty change in the liver, widely distributed internal petechial...

Whooping crane preyed upon by golden eagle

The Golden Eagle (Aquila chrysaetos) is the largest predatory bird in North America and is well known for its predatory abilities. Attacks have been reported on mammals such as whitetail jackrabbits (Lepus townsendi) (McGahan 1967, J. Wildl. Mgmt. 31: 496), pronghorn antelope (Antilocapra americana) (Bruhns 1970, Can. Field-Natur. 84: 301),...

The susceptibility of the mallard duck (Anas platyrhynchos) to Clostridium botulinum C2 toxin

Most strains of Clostridium botulinum type C, after having lost their capacity to produce their dominant toxin (C1) as a result of being“cured”of their prophages, continue to produce C2, a trypsin-activable toxin reported by other investigators. While of relatively low toxicity when administered perorally to the adult mallard duck (Anas...

Organochlorine pesticide, PCB, and PBB residues and necropsy data for bald eagles from 29 states - 1975-77

During 1975-77, 168 bald eagles (Haliaeetus leucocephalus) found moribund or dead in 29 states were analyzed for organochlorine pesticides and polychlorinated biphenyls (PCBs); 32 specimens from 13 states were analyzed for polybrominated biphenyls (PBBs). PCBs were present in 166 bald eagle carcasses and DDE was found in 165. TDE and dieldrin were...

Bordetella bronchiseptica associated with pulmonary disease in mountain voles (Microtus montanus)

Bordetella bronchiseptica was isolated from the lungs of all of six mountain voles (Microtus montanus) found dead or dying of pulmonary infection near the Bear River Research Station in northern Utah in January, 1973. The possibility of concomitant viral or mycoplasmal infection was not ruled out.

Epizootic of coccidiosis in free-flying lesser scaup (Aythya affinis)

A coccidiosis epizootic has occurred in lesser scaup (Aythya affinis) at Bluestem Reservoir in eastern Nebraska during the spring in each of three recent years: 1976-1978. Losses peaked during the period from mid-March through April. As much as 29% of the peak population of scaup using the reservoir died. Necropsies of 72 of the nearly 1390 scaup...

Salmonella meningoencephalomyelitis in a northern fur seal (Callorhinus ursinsus)

Salmonella enteritidis was isolated from the brain of a neonatal northern fur seal (Callorhinus ursinus) with gross and microscopic lesions of meningoencephalomyelitis. Microscopic lesions in the liver and lung suggested septicemia.

The isolation of a herpes virus from captive cranes with an inclusion body disease

A viral agent, identified as a herpesvirus and tentatively called 'inclusion body disease of cranes' (IBDC), was isolated from captive cranes involved in a die-off at the International Crane Foundation near Baraboo, Wisconsin. Preliminary animal susceptibility tests, based on experimental infections, suggested that White Pekin ducklings up to 17...

Type C botulism losses at Horicon National Wildlife Refuge, 1978

Avian botulism was responsible for the death of over 6,000 waterfowl at Horicon National Wildlife Refuge in Wisconsin in 1978. The outbreak occurred in early fall on a flooded 250 hectare fallow agricultural area on the northeast end of the refuge. The species most severely affected was the green-winged teal (Anas carolinensis), which made up...
