Scientists from the USGS Alaska Science Center have been collaborating with colleagues from the University of Tokyo to study migration patterns and breeding distribution of Northern Pintail Ducks and Whooper Swans marked on their wintering areas in Japan. This will help us understand how migratory birds may contribute to the intercontinental transmission of avian influenza viruses.
