Eagle Classification

787 Views
Most of the sixty species of eagles are from Eurasia and Africa. Just fourteen eagle species can be found in other parts of the world – two in the United States and Canada, nine in Central and South America, and three in Australia. Major new research into eagle taxonomy suggests that the important genera Aquila and Hieraaetus are not composed of nearest relatives, and it is likely that a reclassification of these genera will soon take place, with some species being moved to Lophaetus or Ictinaetus.
  • Bonelli’s eagle and the African hawk-eagle have been moved from Hieraaetus to Aquila.
  • Either the Greater Spotted Eagle and Lesser Spotted Eagle should move from Aquila to join the Long-crested Eagle in Lophaetus, or, perhaps better, all three of these species should move to Ictinaetus with the Black Eagle.
  • The Steppe Eagle and Tawny Eagle, once thought to be conspecific, are not even each other’s nearest relatives.
