Polly want a virus? A devastating parrot disease that has pushed one species to the brink of extinction might be spread by a newly-discovered virus. Proventricular dilatation disease – PDD for short – deadens the nerve cells that control the oesophagus and stomach. "Birds can't grind the seeds and digest their food properly, and they waste away," says avian veterinarian Susan Clubb, of the Rainforest Clinic for Birds and Exotics in Loxahatchee, Florida. Veterinarians first spotted the disease in macaws exported from Bolivia in the 1970s. The illness now afflicts dozens of species of psittacines – the group that includes parrots and cockatoos – as well as macaws.

Dead fish, birds point to presence of disease; zebra mussels blamed

Local biologists are bracing for an outbreak of avian botulism, a paralytic disease that kills about 10,000 Great Lakes shorebirds every summer. The conditions are right. Warm temperatures, changing lake levels and decaying vegetation stir up common bacterial spores. Toxins form, and dead fish wash up on the shore. "It hits pretty hard," said Nathan Ramsay, a wildlife disease technician at the U.S. Geological Survey's National Wildlife Health Center in Madison, Wis. "And it's starting again."

USGS and a network of partners across the country work on documenting wildlife mortality events in order to provide timely and accurate information on locations, species and causes of death. This information was updated on Aug 08, 2008 on the USGS National Wildlife Health Center web page, New and Ongoing Wildlife Mortality Events Nationwide. Quarterly Mortality Reports are also available from this page. These reports go back to 1995.

The Great Salt Lake is so briny that swimmers bob in the water like corks. It is teeming with tiny shrimp that were sold for years in the back of comic books as magical "sea monkeys." And, for reasons scientists cannot explain, it is heavily laden with toxic mercury. Exactly where the poison is coming from — and how much danger it poses to the millions of migratory birds that feed on the Great Salt Lake — are now under investigation. "We've got a problem, but we don't know how big it is," said Chris Cline, a U.S. Fish and Wildlife Service biologist who has been collecting the eggs of cinnamon teal ducks from nests along the rim of the lake so that they can be cracked open and analyzed in the lab.
