Prairie Falcon

The Prairie Falcon is a raptor of arid grassland, sagebrush steppe, and canyon country across western North America, filling a role similar to Peregrine Falcon but adapted to drier, more open habitats. Its pale coloration helps it blend into the sandy and rocky landscapes it inhabits.

Back and covert feathers are sandy to grayish-brown with pale feather edges giving a subtly scaled appearance. A distinctive dark blackish-brown patch of underwing covert feathers near the body (the axillaries) is visible in flight and is one of the most reliable field marks for this species. The facial pattern includes a thin dark malar stripe and whitish eyebrow, fainter than the bold moustache of Peregrine Falcon, and the tail is pale brown with only faint banding.

Adults are pale brown above with pale-edged feathers producing a scaled look, and whitish underparts marked with brown spotting and barring. Juveniles are more heavily streaked below and somewhat darker above than adults, gradually acquiring the paler adult pattern. Sexes are similar in plumage, though females are larger, as typical for falcons.

This falcon occupies arid grassland, sagebrush steppe, and canyon or cliff country across western North America. It is largely resident, though some individuals shift to lower elevations or move short distances seasonally in response to weather and prey availability.

It hunts ground squirrels and small birds using fast, low-level pursuit flight over open terrain. Nests are built on cliff ledges, often in canyon country, and the species gives cackling calls, particularly when defending the nest site from intruders.
