Sea-eagles are birds of prey usually found catching fish around large bodies of water and coastlines. Known also as fish eagles, they are not to be confused with the two species of smaller true fish eagles of southeast Asia. Of the eight species of sea eagles there are three obvious species-pairs, for example, the white-tailed sea eagle of Europe and Asia and the bald eagle of north America - they cannot breed together but are physically very similar.
Scientific name: Haliaeetus
