Which Accipiter is noted for being the most migratory?

The Sharp-shinned hawk is recognized as the most migratory among the Accipiter genus. This species typically exhibits a strong migratory behavior, often traveling long distances during the migration season, which can include moving from breeding grounds in North America to wintering sites in Central America and parts of the southern United States.

The migratory pattern of the Sharp-shinned hawk is influenced by factors such as the availability of food, particularly in relation to the migration of small birds, which comprise the bulk of their diet. Their smaller size compared to other Accipiter species allows them to take advantage of various habitats along their migratory routes.

In contrast, while the Cooper's hawk also migrates, its migratory behavior is less pronounced and often more localized. The Goshawk tends to be more sedentary and generally does not migrate over long distances, preferring to remain within its breeding territory unless food supply drastically diminishes. The Merlin, though a falcon and not an Accipiter, does exhibit migratory behavior, yet it is not categorized as the most migratory within the Accipiter families. Thus, the Sharp-shinned hawk stands out due to its extensive migratory tendencies.
