In most of the United States, Red-tailed Hawks are permanent residents. Northern birds migrate further south. Throughout their range in the U.S., red-tailed hawks receive special legal protections under the Migratory Bird Treaty Act of 1918. They have a complex relationship with humans, capable of both controlling rodent and other mammalian pests, and of on occasion being one, taking valuable fowl (which has led to them being one of the species described as a chickenhawk).
