Species
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 Booted 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.

Famous quotes containing the word species:
“Thus all probable reasoning is nothing but a species of sensation. ‘Tis not solely in poetry and music, we must follow our taste and sentiment, but likewise in philosophy, When I am convinc’d of any principle, ‘tis only an idea which strikes more strongly upon me. When I give the preference to one set of arguments above another, I do nothing but decide from my feeling concerning the superiority of their influence.”
—David Hume (1711–1776)
“An unjust law is itself a species of violence. Arrest for its breach is more so.”
—Mohandas K. Gandhi (1869–1948)
“Genius detects through the fly, through the caterpillar, through the grub, through the egg, the constant individual; through countless individuals the fixed species; through many species the genus; through all genera the steadfast type; through all the kingdoms of organized life the eternal unity. Nature is a mutable cloud which is always and never the same.”
—Ralph Waldo Emerson (1803–1882)
