The osprey or fish hawk is a raptor commonly seen along coastlines or inland waterways, where it is sometimes mistaken for the larger bald eagle. The only hawk that actually dives into the water, the osprey hovers above the surface then plunges feet first in its pursuit of fish, the sole constituent of its diet. It may dramatically disappear beneath the surface for a moment and then emerge with a fish seized in its talons before flying off to feed. - RB
