The Peregrine Falcon is a powerful and fast-flying raptor found across Arizona, where it inhabits a variety of landscapes from desert cliffs and river canyons to mountain ranges and, increasingly, urban areas. Known for its remarkable speed, reaching over 200 mph in a hunting stoop, it preys primarily on medium-sized birds, which it captures in midair with extraordinary agility. In Arizona, Peregrine Falcons breed on sheer cliffs and occasionally on tall buildings or bridges, laying 2–4 eggs in simple scrapes. The species was once severely reduced in numbers across North America due to the effects of DDT, but conservation efforts, including pesticide bans and reintroduction programs, have led to a strong recovery. Today, they are considered fairly common year-round residents in suitable habitats, with migratory individuals also passing through during spring and fall.
