Guide to Boreal Birds
The Prairie Falcon is usually found in places far from water, while the Peregrine is nearly always found near a river or lake. The Prairie Falcon's diet consists mainly of birds, which it pursues on the wing but usually captures on or near the ground. Where elevated perches are available, the Prairie Falcon will spend a considerable amount of time watching for prey. In open country without high perches, the style of hunting is to fly low above the ground and flush prey.
