Bird Watcher features full motion video as well as authentic bird calls and songs, and includes interactive modules such as Raptor Hunting Games where you take flight and hunt for ground and water based prey, a Bird Watcher's Reference Guide, a Wild Bird Reference Tool, and a section on the use of optics to enhance birding techniques. The intuitive interface (keyboard, mouse or joystick), photo-realistic bird environments, a geographical guide and choice of exploration or competition (one or two players) rounds out the offerings, with noted author and Director of the New Jersey Audubon Society's Cape May Bird Observatory, Pete Dunne, providing narration.
