It is usually centered around the bird's favorite perch, nesting ground, or hunting grounds. The nest is preferably on a rocky cliff looking over the country side. This nesting choice is to spot prey. The area needs to have plenty of pigeons and song birds. Song birds and pigeons are the falcons' food, as well as other small rodents.
Falcons have a unique way of catching their food.
Whenever a falcon spots its prey the falcon circles around the area. Next it dives down out of the sky and strikes its prey. The peregrine then circles back and snatches the falling prey out of the sky. The prey is then taken back to the young for their food. In the 1950's the peregrine population decreased rapidly and very unexpectedly.
