Why did the peregrine falcon adapt into the grassland?

The peregrine falcon adapted to grassland habitats to exploit the availability of prey, such as small mammals and birds, which thrive in open areas. This adaptation allows the falcon to utilize its exceptional speed and hunting skills in a less cluttered environment, enhancing its hunting efficiency. Additionally, grasslands provide optimal nesting sites and fewer obstructions for their high-speed dives, making them a suitable habitat for breeding and raising young.
