How much space does a peregrine falcon need?

A peregrine falcon's territory size varies depending on the availability of prey, habitat suitability, and the density of conspecifics. In general, peregrine falcons require a large territory to support their hunting needs. On average, a pair of peregrine falcons may have a breeding territory ranging from 1 to 62 square miles (3 to 160 square kilometers).

During the nesting season, the nesting territory is defended vigorously, and the size of the defended area around the nest site may be smaller, typically ranging from 0.5 to 2.5 square miles (1.3 to 6.5 square kilometers). Outside the breeding season, peregrine falcons may have larger home ranges, which can be several times larger than their nesting territory. These ranges allow them to move freely and search for food over a wider area.

To summarize, a peregrine falcon's typical territory size ranges from several square miles to tens of square miles, depending on various factors that influence their habitat and prey requirements.
