The Peregrine Falcon was once considered quite rare because of pesticide poisoning but has since made a comeback and sightings are increasing every year.
The Peregrine Falcon is the fastest bird on earth, capable of diving from great heights at speeds of up to 200 miles per hour. It is a beautiful raptor with long, pointed wings and a long, slightly rounded tail. Adults have a bluish-gray to slate-gray backside and a buffy white underside interspersed with black. Adults also possess a black crown, black moustache-like markings or “sideburns”, a white throat, a dark bill with a prominent yellow fleshy base (or cere), and yellow legs and feet.
Peregrines prefer cliff nest sites such as on Mount Tom. In general, Peregrine falcons prefer to nest on cliffs or man-made structures overlooking a body of water like the Connecticut River Valley.
