Discussion Large, stocky falcon. Confusion with juvenile Peregrine is possible, but Prairie is paler overall, with less contrast on head; note pale behind eye. In flight, from below, Prairie looks very pale (especially tail), except for dark bar on outer coverts and axillaries (juvenile Peregrine is uniformly barred and streaked gray below, palest on throat and vent). Typically hunts at low levels for small mammals and birds (Peregrine usually dives from a great height). Sexes are similar.
