Migration routes and population status of the Brent Goose Branta bernicla nigricans wintering in East Asia
Of the world's Brent Goose Branta bernicla populations, the migration routes and winter distribution of the East Asian population of Brent Geese B. b. nigricans are the least well known. We therefore marked Brent Geese at their primary pre-migratory staging area in Notsuke Bay, Hokkaido, Japan...
