Field ID: Eagles

Novasola is home to two endemic species of eagle, the Paramount and Novasola Sea Eagles. These eagles are the second and third largest birds of prey on the island, behind only the Novasola Condor, and among the heaviest birds as well, along with the condor and cranes. These eagles can be difficult to differentiate, and these visual guides are meant to help clarify some major visual differences. 

Below are pictures and information meant to help differentiate the two species in the field. For the full field guide entry for the Novasola Sea Eagle, click here. For the full field guide entry for the Paramount Eagle, click here.

The best way to tell these species apart are by habitat and behavior. While the Novasola Sea Eagle is found exclusively near bodies of water and mainly eat fish and carrion, the Paramount Eagle can be found in arid regions and away from water, and mainly eat terrestrial prey. The Sea Eagle is much more social and vocal, and is more likely to be seen in groups or heard making calls. They are also more comfortable with human development and can be seen along city waterways. 

Visually, the two eagle species have some diagnostic differences. The Paramount Eagle is in general smaller, though the largest female Paramounts may approach the size of smaller male Sea Eagles. The Sea Eagle's head and bill are larger and appear much bulkier. In adult plumage, Paramount Eagles are darker, with darker heads and tails and lack white shoulders, instead with light wing spotting. Juveniles in both species are darker overall, but juvenile Paramounts have a light-colored tail with a diagnostic dark band. In flight, Sea Eagles have broader, longer wings with a white leading edge and a short tail. Paramounts have a longer tail and smaller head, with light-colored striping in the wing undersides.
