The Imperial Eagle, Aquila heliaca, is very similar to the Golden Eagle, but slightly smaller in body length (80 cm) and wingspan (200 cm). Like all eagles, A. heliaca belongs to the bird of prey family Accipitridae. Imperial Eagles are distributed throughout southeastern Europe as well as western and central Asia. The Spanish Imperial Eagle, found in Spain and Portugal, was formerly lumped with this species, the name Imperial Eagle being used in both circumstances. However, the two are now regarded as separate species due to significant differences in morphology, ecology and molecular characteristics.
