Discussion Ospreys
search for fish by flying and hovering over the water, watching the surface
below. When prey is sighted, an Osprey dives steeply, its talons outspread, and
splashes into the water. It quickly resurfaces and, if it has made a catch,
flies off, adjusting the fish in its claws so that the head is pointed forward.
Ospreys declined drastically because of pesticides during the 1950s and 1960s,
but since then they have made a comeback and are nesting again in areas from
which they had disappeared.
