The peregrine falcon is considered one of the fastest species in the world, reaching up to 250 kilometers per hour. Denoted at North America’s most well known raptor (bird of prey), it is also one of the most widely distributed birds; having up to nineteen subspecies- including the American peregrine falcon. The average lifespan lasts from 7-15 years, although some may survive up to 20 years. These birds have a wingspan of 3.5 feet and weigh about 2 lbs.

The Latin derivation of perigrinus means ‘to wander’. This is extremely fitting for this raptor, for it is known to travel and reside in every continent except for Antarctica. The American peregrine falcon can only be found in Denali National Park and Preserve in the northern interior of Alaska, United States of America.

During previous years of DDT (dichlorodiphenyltrichloroethane) use during World War II as a synthetic pesticide, a rapid declination of peregrine falcon occurred. It caused the eggshell to thin, causing the eggshell to break while being incubated. This obviously decreased the population of this species.

Ever since the ban of the DDT pesticide, the population began to subtly increase and recover. In Denali National Park, the population had rapidly increased from 1980 and continuing into the present. In 1988, the first breeding pair of falcons were found in Denali. Denali researchers and scientists continue to search for more breeding pairs and count the population of these falcons over the years.
