early starters - a southbound skein

it's only september, but these canada geese have begun their journey southbound for the coming winter. geese fly in v formation for several reasons, primarily to boost flight efficiency and improve range through reduced drag. all birds, apart from the lead bird, are flying in the upwash of the birds ahead. the birds rotate through the lead position to reduce fatigue. birds are also better able to communicate and to keep an eye on one another in this formation.
