Bald Eagle

Haliaeetus leucocephalus

Not bald at all, just white-headed, which is exactly what its scientific name leucocephalus means in Greek: 'white head.' Why English says 'bald' is still argued over: it may be an old word for white-marked, or just how bare that white head looks.

Haliaeetus means 'sea eagle'; leucocephalus is Greek for 'white head.'
