"It's pretty clear, between what the National Wildlife lab found and from the Southeast Cooperative, that there is a new virus found in eiders in Wellfleet that hasn't been detected before," said Sarah Courchesne, project director for the Seabird Ecological Assessment Network at Tufts veterinary school...
...Loosely related to the flu virus, it attacks the liver and gallbladders and seems to work very fast. Eider ducks collected from these mass die-offs appear healthy. They are not emaciated from a long illness in which they can't feed...
...So far, Wellfleet Bay is the only place in the world known to harbor this virus, although the scientists believe it is related to an equally mysterious Quarjavirus family that is distributed around the world. Ticks spread the diseases in colonies of nesting birds...
