The Osprey’s diet consists almost completely of fish. David Gessner (who calls himself an ospreyologist) writes in his book, Return of the Osprey, that the osprey is the only raptor to dive completely under water to go after its prey. The bird can hover 50-ft. or more in the air to spot a fish, then dive headfirst at 40 miles per hour, yet still hit the water upright, talons extended to grab the fish in its sights. As it hits the water, it closes its third eye lid, which acts as goggles so he can see the fish. Ospreys always reposition the fish in their claws so that the fish are head first, the most streamlined way to carry them. The Osprey military craft was well named; it can hover, and go rapidly into a climb or a dive, also.
If I had to choose, I would rather have birds than airplanes. – Charles Lindbergh
