Which raptor is most likely to travel the longest distance during migration?

The Merlin is recognized for its impressive migratory patterns, often covering significant distances as it travels between breeding and wintering grounds. This small falcon is known for its adaptability and can migrate thousands of miles, with some populations breeding in the Arctic regions and wintering in areas as far south as Central America.

In contrast, while other raptors such as the Gyrfalcon and Prairie Falcon also migrate, their distances are generally shorter when compared to the substantial journeys undertaken by Merlins. The Goshawk is more of a resident species in many areas, with migration being less pronounced. Collectively, these factors underline why the Merlin is considered the raptor most likely to travel the longest distance during migration.
