National Geographic Museum will host two interactive traveling exhibitions that spotlight the natural world this fall. “Geckos: Tails to Toepads,” open from Sept. 24 through Jan. 5, 2011, showcases more than 75 live geckos from around the world and highlights their fascinating adaptability and wide range of habitats. “Wild Music: Sounds & Songs for Life,” on display from Oct. 1 through Jan. 2, 2011, explores the biological origins of music and the soundscapes that surround and musically inspire both humans and animals. Both exhibitions will be in the Museum’s 17th Street building.
