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

The Merlin is known for its extensive migratory behavior, often traveling significant distances between its breeding and wintering grounds. These small falcons, which are highly adaptable, are capable of covering long distances, sometimes migrating thousands of miles. Their migratory patterns are often influenced by weather conditions and food availability, making them one of the raptors that have a well-documented tendency to undertake long journeys during migration.

In contrast, while the other raptors listed also migrate, they typically do not travel as far as the Merlin. The Prairie Falcon, for example, has a more localized migratory pattern primarily within North America. Goshawks tend to migrate shorter distances when compared to Merlins, focusing more on seasonal movements within their home territories. The Gyrfalcon, although capable of long flights, generally migrates less extensively and tends to remain within certain Arctic regions. Thus, the Merlin stands out as the raptor most likely to travel the farthest during migration.
