v Osprey
Osprey is a large powerful raptor. The species name of Osprey is Pandion
haliaetus carolinensis. This Florida
bird has been a symbol of plight of the Chesepeake Bay for several years.
They have a large, narrow-winged hawk with wings tapering to a rounded
tip and a short hooked beak.
They are found in rivers, lakes and shallow water estuaries. They usually build their nests under tall, offshore structures such as channel markers and duck blinds to protect their young ones. The nests are made up of dry sticks and they are placed at the top of live/dead trees.
In areas of low-fish plethora only one osprey nestling will survive but in highly productive areas two or three may survive each year. Ospreys are generally spectacular divers. They also perform shallow scoops for fish near the surface.
Their count has decreased dramatically in 1960 particularly in the bay region due to the widespread use of pesticides such as DDT and so it results in lower hatch rates since it has influenced the birds to lay eggs with extremely thin shells.
In 1972 US has banned DDT and the setback of the coast guard’s
policy of dismantling
Osprey nests on channel markers, their numbers has begun to bounce back
and so today
Osprey has become a common sight and it is estimated that more than 2000
pairs are nested in the Bay Area.
