The Ducks' Migration (2012)

Two boys and close family friends, Jeremy and Alphonse, American and French, spend a few weeks together in Jeremy’s house in Brooklyn. Jeremy is confused about his understanding of the friendship, while obsessed with the ducks in the Prospect Park’s lake and finishing a school paper about their migration. Alphonse likes to ride bicycles and doesn’t want to leave town. The ducks inevitably leave, Alphonse goes back to Paris, and Jeremy stays in his house, but all of them depart to something new.
