NYT: The latest victims are common murres in the Northeast Pacific. They have been dying for months, but estimates of the toll jumped sharply when David Irons, a retired United States Fish and Wildlife Service biologist walking a beach in Whittier, Alaska, found close to 8,000 dead birds in early January.
The birds are emaciated and seem to be starving, according to the National Wildlife Health Center in Wisconsin, which has found no evidence of disease or toxins that could cause such deaths.
When there are changes in water temperature, as has been occurring in the Northeast Pacific, food fish may disappear.
