Sir Nigel Archibald Thornberry, KBE (born April 19, 1951) is the host of Nigel Thornberry's Wild World. Nigel has devoted his entire life to studying all kinds of wild animals and their habitats. His dry wit and hearty laugh are almost as noticeable as his bright red hair and bushy mustache. Besides narrating the show, he is an experienced pilot and wood grower and has often risked life and limb to save his wife and daughters from extremely perilous situations they find themselves in on their travels. He was recently knighted by the Queen of England and even considered taking a professorship at Oxford in order to allow his daughters to have "normal" lives and to have human friends (in Eliza's case), but even this honor won't quench the need for adventure in his blood as he continues his journeys to the far corners of the globe in search of one elusive species after another.
Nigel has red hair and mustache. He often wears a khaki shirt and green shorts.
Nigel appears in every episode of The Wild Thornberrys. His first appearance was in "Pilot". His last appearance was in "Eliza Unplugged". Nigel has a supporting role in The Wild Thornberrys Movie, he had a bigger role in Rugrats Go Wild!.
