Chlamydial infections in free-living birds

Most studies of chlamydial infections in free-living wild birds have been limited to surveys for the presence of Chlamydia psittaci or antibody to C psittaci and have largely been done in association with the identification of chlamydiosis in human beings, commercial fowl, or pet birds. The emphasis of these studies has been to determine the...

Fusarium mycotoxins from peanuts suspected as a cause of sandhill crane mortality

An estimated 9,500 sandhill cranes (Grus canadensis) died in Gaines County, Texas and Roosevelt County, New Mexico between 1982 and 1987. The predominant clinical sign observed in sick cranes was their inability to hold their heads erect, both while standing and flying. Multiple muscle hemorrhages and submandibular edema were the most common...

Microcontaminants and reproductive impairment of the Forster's tern on Green Bay, Lake Michigan,1983

For the 1983 nesting season, Forster's tern (Sterna forsteri) reproductive success was significantly impaired on organochlorine contaminated Green Bay, Lake Michigan compared to a relatively uncontaminated inland location at Lake Poygan, Wisconsin. Compared with tern eggs from Lake Poygan, eggs from Green Bay had significantly higher median...

New species of Apoloniinae (Acari: Trombiculidae) from the Laysan albatross taken in the Midway Islands and key to the species of Apoloniinae of the world

Womersia midwayensis Goff, Sievert and Sileo is described as a new species from specimens taken off a Laysan albatross chick, Diomedea immutabilis (L.), collected on Sand Island, Midway Islands. A key to the genera and species of larval Apoloniinae of the world is given.

Presumed drowning of Aleutian Canada geese on the Pacific coast of California and Oregon

Carcasses of 42 and 17 Aleutian Canada geese (Branta canadensis leucopareia), a federally listed endangered species, were found on ocean beaches near Crescent City, California, and near Pacific City, Oregon, respectively, following severe storms. Necropsies and other information suggest that the birds were flushed during the storms and somehow...

Sightability adjustment methods for aerial surveys of wildlife populations

Aerial surveys are routinely conducted to estimate the abundance of wildlife species and the rate of population change. However, sightability of animal groups is acknowledged as a significant source of bias in these estimates. Recent research has focused on the development of sightability models to predict the probability of sighting groups under...

Characterization of an avian cholera epizootic in wild birds in western Nebraska

Avian cholera killed an estimated 2500 birds in western Nebraska and eastern Wyoming from 28 November 1985 to late January 1986. Wild mallards (Anas platyrhynchos) suffered the most losses. Other wild waterfowl, wild turkeys (Meleagris gallopavo), a few domestic fowl, and a bald eagle (Haliaeetus leucocephalus) also died. Pasteurella multocida...

Eustrongylides sp. epizootic in young common egrets (Casmerodius albus)

In May 1985, epizootic mortality was reported in common egrets (Casmerodius albus) on Avery Island, Louisiana. Subsequent investigation revealed that more than 400 birds died. Severe peritoneal nematodiasis (Eustrongylides sp.) was found on postmortem examination. A nearby breeding rookery on the same island was apparently unaffected. Reasons for...
