Hemorrhagic enteritis in captive American kestrels (Falco sparverius)

Hemorrhagic enteritis and hepatitis of suspected adenovirus etiology were the apparent cause of death of nine captive American kestrels. Cloacal hemorrhage was the only prominent gross lesion: disseminated hepatocellular necrosis, and intranuclear inclusion bodies were evident microscopically. Electron microscopy revealed numerous adenovirus-like particles associated with the hepatic lesions. Atte

The bile acid composition of crane gallbladder bile

1. The biliary bile acids of the whooping crane (Grus americana) and the Florida sandhill crane (G. canadensis pratensis) have been examined.2. Cholic acid (CA), chenodeoxycholic acid (CDOCA) and lithocholic acid were found in bile from both species of these North American cranes.3. CDOCA and CA were the primary bile acids in both species, together constituting 70% or more of the bile acids by wei

Halogenated diphenyl ethers identified in avian tissues and eggs by GC/MS

Chlorinated and brominated diphenyl ether compounds (DPEs) have been detected by gas Chromatography/ mass spectrometry (GC/MS) in eggs and carcasses of fish-eating birds from Louisiana, Michigan, Ohio, Rhode Island, Texas, Virginia, and Ontario, Canada. Three of these compounds were quantified; the highest concentration of 0.90 ppm tetrachloro DPE was found in a common tern carcass (Sterna hirund

Chewing-removal of radio collars by wolves in Wisconsin

From May 1980 through august 1981 we placed 11 machine-belt radio collars on 10 adult gray wolves (Canis lupus) from 4 packs in northwestern Wisconsin. This note reports the loss of 7 collars from chewing by other wolves, apparently pack-mates.

Factors affecting the distribution of mallards wintering in the Mississippi alluvial valley

The Mississippi Alluvial Valley (MAV) is the principal wintering area for Mallards (Anas platyrhynchos) in the Mississippi Flyway. Here, we consider it a distinct habitat (sensu Fretwell 1972), i.e. fitness is relatively homogeneous among ducks within the MAV but different from that of ducks in other such habitats. We analyzed recovery distributions of Mallards banded preseason (July-September 195
