Which hawk is known for having the widest geographic distribution?

The Peregrine falcon is known for its extensive geographic distribution, being one of the most widespread bird species worldwide. It can be found on every continent except Antarctica, occupying a diverse range of habitats, including urban areas, mountains, and coastal regions. This adaptability to various environments contributes significantly to its wide distribution.

In contrast, the other birds listed have more limited ranges or are specifically associated with certain habitats. The Gyrfalcon, for example, is primarily found in the Arctic regions and has a more localized distribution compared to the Peregrine falcon. Cooper's hawk is largely an American bird, primarily inhabiting forested areas and suburban regions of North America. The Marsh hawk, also known as the Northern harrier, tends to inhabit wetlands and grasslands, which limits its geographic range.

Thus, the Peregrine falcon stands out for its remarkable ability to thrive in diverse environments across a global scale, leading to its recognition as the hawk with the widest geographic distribution.
