Issued in 1968, this 6¢ United States stamp celebrates Waterfowl Conservation and depicts a striking pair of Wood Ducks (Aix sponsa) in flight. The vibrant plumage of the male and the more subdued tones of the female highlight the species’ natural beauty and the importance of wetland protection. Designed to raise awareness for wildlife preservation, this issue reflects the U.S. Postal Service’s ongoing support for conservation themes during the 1960s. It remains a favorite among collectors for its vivid colors and educational message.
