American Kestrel
Falcons are swift, agile raptors known for their exceptional hunting skills, sharp vision, and streamlined bodies built for speed. The most widespread is the American Kestrel (Falco sparverius), a small, colorful falcon often seen perched on wires or hovering over fields in search of insects and small vertebrates. The Merlin (Falco columbarius) is a compact, fast-flying falcon that winters in Arizona, preying on small birds in open country and urban areas. The Peregrine Falcon (Falco peregrinus), famous for its high-speed stoops that can exceed 200 mph, nests on cliffs and tall structures and hunts medium-sized birds. The Prairie Falcon (Falco mexicanus), a pale, desert-adapted species, inhabits open grasslands and arid landscapes, often seen soaring over canyons and mesas. All four species are protected, with Peregrine Falcons making a notable conservation comeback after mid-20th-century declines. Arizona’s diverse habitats—from grasslands and deserts to mountain cliffs—provide year-round or seasonal homes for these powerful aerial hunters.
