With more than 10 million serious bird-watchers in the country, Rupicola VCR Games, in Walpole, Mass., figures there's a market for an indoor version of the sport. Gone Birding! is a bird-identification VCR board game with a two-hour video, hosted by actress Jane Alexander, an avid birder. The National Audubon Society is marketing the game to members.
