Patagonian Mountains

S1 E3: Natural history series about wildlife at night culminates at the wild and windswept tip of South America. Coming face to face with the widest ranging cat in the Americas – the puma – camerawoman Justine Evans attempts to film their nocturnal hunting behaviour for the first time. Even further south, Gordon Buchanan dives into the icy waters of the Magellan Strait to solve a mystery - scientists have heard humpback whales moving close to the shore at night but have no idea what they could be doing. And Dr George McGavin attaches a miniature tracking device to a vampire bat’s back, to discover whose blood it is feeding on.
