Tim Braunel, Green Bay, Wis.
Braunel, together with friend Joe Loehlein, leads an effort to rescue imperiled mallards in urban areas and release them in rural marshes. Their group, the Green Bay Duck Hunters Association, has been providing this service for more than three decades. Since 1996, the duo has helped round up more than 7,700 ducks that otherwise would have been vulnerable to traffic and predation. "It's a form of giving back," Braunel says, "but it's working with the actual resource."
