Sir Nigel Archibald Thornberry 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, Nigel is an experienced pilot and wood grower, and has often risked life and limb to save his family from extremely perilous situations they find themselves in on their travels. Nigel has recently been knighted by the Queen of England, 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. Although Nigel considered taking a professorship at Oxford in order to allow his children to have "normal" lives, and to have human friends in Eliza's case. There was one instance that Nigel had muttered "That it would be far easier to raise crocodiles", when Eliza and Debbie had gotten into another argument.
