Ducks Unlimited

If it walks like a duck and talks like a duck ... Ducks Unlimited wants to protect its habitat. The not-for-profit group works to conserve, manage, and restore wetlands and other waterfowl habitat through projects across North America and in more than 10 South American nations. With more than 12 million acres under its care, DU's efforts are aimed at ducks but also benefit more than 900 other wildlife species. Most of the organization's members and volunteers are sport hunters and DU puts out a magazine, cable TV show, and daily radio show for them. It also offers training in hunter ethics, firearm safety, and conservation and other programs for children. DU was founded in 1937 and has than 770,000 members.
