Episode 3

Zoologist Nigel Marven explores the wildlife of the Canadian Arctic. Summer arrives in the Inuit community of Igloolik in the far north of the country, where Nigel watches bowhead whales and dives from an iceberg to swim with walruses. In Churchill, he catches up with the nine fox cubs; attempts to catch a speeding lemming; and dives with beluga whales in the freezing river. In the boreal forest to the south, great the grey owl chicks are climbing the trees.
