Description: A crowned eagle seen from the front, with wings spread, head turned to one side, and talons outstretched left and right.
Description of difference: Eagles in Group A have the lower claw on the side of the beak. The top of the wing on the side of the beak is farther away from the head than the opposite wing.
Potential Twin: Eagle – Group B (Leicester Sheet 3)
