Chris Packham’s Animal Einsteins

BBC2, 8pm

Over six weeks, the Winterwatch presenter (above) profiles some of the most cunning creatures, communicators, builders, social networkers, con artists and travellers of the animal kingdom. Tonight he demonstrates the New Caledonian crow’s tool-making prowess, while Samadi Galpayage shows how bees add up in a similar way to humans counting on their fingers.
