The long-winged harrier (Circus buffoni) is a species of bird of prey in the family Accipitridae, native to South America. The Long-Winged Harrier grows to be “19-21.25 inches (48-55cm) tall with a wingspan of 47 to 61 inches (119-155 cm)”(Schulenberg, Stotz, Lane, O’Neill, Parker & 2010, p.114). This bird is long-legged and long-tailed with a slender build, allowing it to cruise in its search for food. The appearance of the harriers’ feathers/plumages vary, but the face feathers are usually arranged in a disc shape. One consistency is that “all plumages shows gray primaries, tipped and barred with black (visible in flight), and dark, solid-colored upperparts”(Schulenberg, Stotz, Lane, O’Neill, Parker & 2010, p.114).
