Date of Issue : 20 January 2012
The U.S. Postal Service issued a set of five stamps on 20 January 2012 featuring the Birds of Prey stamps: the northern goshawk (Accipiter gentilis), peregrine falcon (Falco peregrinus), golden eagle (Aquila chrysaetos), osprey (Pandion haliaetus), and northern harrier (Circus cyaneus).
These powerful birds are depicted in colorful portraits and shown from the neck up. Birds of prey, also known as raptors, thrive in diverse habitats and live on every continent except Antarctica. The roughly 500 species of raptors include birds that hunt by day, such as falcons, eagles, and harriers, and birds that hunt by night — the owls. They share several common characteristics. Birds of prey are carnivorous and use their powerful talons to capture prey. Their exceptionally keen eyesight allows them to see small objects in detail, even from a great distance. As predators high on the food chain, raptors play an important role in maintaining the balance of nature.
