Ian Walton Fowles (born 1979) is an American musician, author, and actor, best known as the current guitarist for the Orange County rock band The Aquabats, in which he performs under the stage name and persona of Eagle "Bones" Falconhawk (alternately EagleBones Falconhawk). Prior to joining The Aquabats, Fowles was also one of the founding members of the hardcore punk band Death by Stereo.
Fowles grew up in Orange County, and started playing guitar in his early teen years, claiming to have been inspired by seeing the guitarist character of Marty McFly in the film Back to the Future. By the age of 14, he was regularly playing in local punk bands, eventually becoming part of the original formation of Death by Stereo in 1996. Fowles remained in the group's line-up until late 1998, when he left to serve a two-year mission for the LDS Church in Ohio.
In 2006, Fowles joined The Aquabats as a full-time member, succeeding longtime guitarist Courtney Pollock (aka "Chainsaw, the Prince of Karate"). His stage name was conceived in The Aquabats' van during his first tour with the group: "Bones" was derived from his slender stature, while the bird names were playing off his surname's similarity to "fowl". Fowles appeared in character on a 2007 episode of Yo Gabba Gabba!, playing a guitar solo as part of the show's "Cool Tricks" segment, and as of 2012, he currently portrays his fictionalized counterpart on The Aquabats' cable television series The Aquabats! Super Show!.
