Osprey
[Pandion haliaetus]
[Length 23 in. Wingspan 63 in.]
Osprey breed along coasts and lakes throughout much of Canada and Alaska, the northwestern US, the Great Lakes, and along the eastern and gulf coasts of the US.
They suffered heavy losses in North America during the 1950s, 1960s, and 1970s due to pesticides (primarily DDT), which caused eggs with thin shells to be laid.
They are recovering due to the ban of harmful pesticides and have returned to many traditional nesting sites.
Osprey feed exclusively on fish, which they hunt by hovering over a pond or lake and then diving feet-first into the water to grab the fish with their strong talons.
Their feet have spiny projections on the soles, an evolutionary adaptation which helps hold the fish in flight.
As they fly away with their catch, they hold the fish with one leg in front of the other, which is thought to reduce the wind resistance of the fish.
This Osprey was photographed as it hovered over a pond in Everglades National Park, Florida, USA.
