The Peregrine Falcon has adapted to live near rivers, grasslands, agricultural land, and near the tops of large buildings or cliffs. You will rarely see a Peregrine Falcon near mountains or by a desert. Peregrines like to nest near the tops or large buildings or cliffs because they are able to see their prey below them and then all they would have to do is to dive from their nesting spot and grab or knock their prey from out of the air. Peregrines are a migratory bird and in the winter, they migrate south to South America and along the Eastern coast of the United States and Mexico. During the summer for breading, Peregrines can be found in Midwestern United States to stretching all the way up to Alaska and northern Canada. Peregrines can be found year-round In most of the Western United States , Mexican, and Canadian coastline.
