North America

55 mins

The bird's eye camera mainly shows North American species migrating, like geese from Mexico to Canada, whose routes are the basis for the program's itinerary. Also shown are seagulls leaving San Francisco's docks to eat specialized flies at a poisonous lake, eagles going for part of the grizzly bears' salmon catch, buzzards hunting in groups, parasite-pickers on buffaloes and waterfowl simpling joining in when dolphins drive fish onto the shore.
