Utah officials suspect bald eagle deaths linked to die-off of shore birds

The tally of unexplained bald eagle deaths in Utah this month rose to 20 on Thursday as state wildlife officials looked for possible links to diseases suspected in a coinciding die-off of thousands of shore birds around the Great Salt Lake. Since December 1, state wildlife specialists have documented a growing number of bald eagles of varying ages succumbing to an unexplained ailment that crippled them with leg paralysis and tremors before they died. Necropsies, the animal equivalent of autopsy examinations, have yet to pinpoint what is killing the eagles, but scientists now believe a disease rather than a toxin is the culprit, said Leslie McFarlane, Utah wildlife disease coordinator. McFarlane said a recent die-off in Utah of eared grebes that began in November and has now killed thousands of birds may be tied to the deaths of eagles, which are known to prey on the small shore birds.
