Watch as birds solve puzzles and challenge our basic notions of intelligence. Call somebody a “bird brain,” and you’re not delivering them a compliment. But as NOVA shows, birds turn out to have advanced problem-solving skills that we usually assume are unique to humans. Watch astonishing tests of avian aptitude: parrots that can plan for the future, jackdaws that can “read” human faces, and crows that can solve multi-step puzzles with tools like pebbles, sticks, and hooks. Could these just be clever tricks based on instinct or triggered by subtle cues from their human handlers? To rule out any doubts, NOVA puts feathered Einsteins through their paces and reveals skills that even three- or four-year-old children have a hard time mastering—such as putting off one reward now to get a bigger one later. From this revolution in thinking about our feathered friends, the conclusion seems irresistible that bird brains see the world in ways that aren’t so different from our own.
The team pushes further into the jungle wilderness, searching for unusual and endangered animals that live there. Base camp is invaded by scorpions and poisonous centipedes, while Gordon Buchanan discovers an animal thief helping itself to base camp supplies.
In the heart of the Atlantic, Gordon Buchanan joins a team looking to discover why huge numbers of devil rays, fish with 'wings' nearly four metres across, and gather every summer near the Azores archipelago. In northeast Turkey the on-board cameras are carried by brown bears as part of a study trying to understand why so many bears survive in a small patch of forest. In southern France on-board cameras help scientists trying to prove that guard dogs can help protect sheep flocks from wolf attacks. The night-vision cameras show how the dogs work together as a team to fend off the wolves.
