Physical description Click here for a physical description Spanish Imperial Eagles are large eagles. The sexes are alike, although females are both larger and heavier than males. The adult plumage (both front and back) is mostly dark-grey (near-black), with dark-brown edge lining on the upperwing coverts. The back of the head, from the supercilia backwards, and hindneck are white, while the inner tail is light-grey. Also the inner wings have a white leading edge and prominent "landing light" patches. The outer tail is dark-grey. The underwing coverts are dark-grey, with slightly lighter grey flight feathers. Spanish Imperial Eagles have pale irises. Their strong bill is light-grey with a dark tip and yellow cere. The legs are completely feathered; the feet are yellow. Juveniles are rufous-brown throughout, except for the flight feathers, which are grey, with white tips and with inconspicuous grey wing panels. In flight the white tips on the wing feathers show as neat white bars, once of which is the trailing edge. Immature Spanish Imperial Eagles, through 5 moults, become gradually darker from the juvenile phase, with mottled and streaked parts coalescing successively into dark-grey plumage. Sub-adults have a dark upper body and dark carpal patches on the underwings.

Range, habitat, finding this species Click here for information on habitat and range The overall distribution of this species can be assessed, and specific locations where birds have been spotted can be found, based on individual sighting reports submitted by birdwatchers to ebird.org . The global distribution of the Spanish Imperial Eagle is available HERE . Spanish Imperial Eagles are endemic to the Iberian peninsula. Their range extends from Gibraltar in the South in a broad swathe into the central parts of Spain and beyond. There are some records of the species in the North of the peninsula as well, up to the Pyrenees.
