The BBC Wildlife Specials are a series of nature documentary programmes commissioned by BBC Television. The series premiered in 1995, and 22 specials have been produced to date, with most of the more recent ones consisting of multiple episodes. The earlier programmes were produced in-house by the BBC's Natural History Unit, but the more recent Spy in the ... titles were made by the independent John Downer Productions. The first 18 specials, through 2008, were narrated by David Attenborough. Polar Bear: Spy on the Ice (2010), Penguins: Spy in the Huddle (2013) and Dolphins: Spy in the Pod (2014) were narrated by David Tennant.
