  Return of the Peregrine   Prior to World War II, the Peregrine Falcon was a rare breeder in Connecticut and was uncommon to rare throughout the year.  By the mid-1960s as a direct result of the widespread agricultural use of the organochlorine biocide DDT, peregrines were extirpated as breeding birds east of the Rocky Mountains.  Three events since then have led to the reestablishment of this species throughout the eastern United States:  the banning of the sale of DDT in the U. S. in 1972; the listing of the Peregrine Falcon on the U.S. Endangered Species Act of 1973; the reintroduction of captive peregrines to the East in the late 1960s, 1970s, and 1980s.  The highly successful recovery program has resulted in the removal of the peregrine from the U.S. ESA in 1999.  Peregrine Falcon recently has been changed from endangered to threatened on Connecticut’s list of rare and endangered species.   Steve discusses the five known nest sites of peregrines in Connecticut during the period 1850-1948.  He then summarizes his ongoing studies of the peregrines that have been nesting at West Rock Ridge State Park in Woodbridge since his discovery of a pair of falcons there in 1999.  Peregrine life history strategies are the focus of these studies:  territoriality, behavior, vocalizations, foraging, mating, nest site selection and preparation, egg-laying, care of nestlings, nest success, and the changing local population of adults.  In the 2000 breeding season, the West Rock peregrines produced the first egg to be laid on a Connecticut cliff in 60 years.
