Migrating Trumpeter Swans
Their aerodynamic V-formation made me think they were geese. But their straight necks and black feet that do not extend beyond the tail showed that they were swans. The lack of black tipped primary feathers shows that they are not Whooping Cranes. They were flying at high altitude and this was taken at 400 mm. Enlargement shows there to be one Canadian Goose that has joined the swans.
