Pre-Extirpation Fecundity, Survival and Management: Historically Falco Peregrinus (Peregrine Falcon) could be seen in all 50 states; in the early 1900’s there were an estimated 400 breeding pairs east of the Mississippi, however by 1965 not a single pair remained (Heinrich, 2009). In order to fully examine the fecundity and survival of modern reintroduced populations and the impact of human actions we must first understand the historical life-histories of these birds. Historical research shows that female American Peregrines reach sexual maturity between one and two years of age and produce an average clutch size of 3.72 eggs with 76.7% hatching successfully, producing roughly 54% males and 46% females (Hickey, 1942). Additional research identified habitat and prey preferences; finding particularly high cliffs overlooking water as the preferred nesting habitat (Bond, 1946) and that nesting on man-made structures was exceedingly rare (De Groot, 1927), the preferred prey was identified as shorebirds (Hickey, 1942). Unfortunately further research into the life histories (max age, age related fecundity, etc.) did not take place prior to their extirpation. However despite this lack of research it was identified that Peregrine populations where already declining due to lack of management practices, hunting, and egg collection (Department of the Interior, 1937). This historical information is vital in examining both the decline and extirpation as well as the reintroduction and current status of the Peregrine Falcon.

4. Current Management Techniques -KYLE

Management Development & Predictive Population Analysis: The Falco Peregrinus (Peregrine Falcon) population throughout the world rapidly declined from the 1930’s-1960’s and was extirpated from much of its historical range, and massive management regulations and breeding programs where necessary to restore it to much of its native...
