What is a characteristic of Parabuteos used for falconry in North America?

Parabuteo, commonly known as the Ferruginous Hawk, exhibits a unique characteristic in that they may be hunted in groups. This behavior is particularly notable among some raptor species and can enhance hunting efficiency as they work together to locate and capture prey. Group hunting can provide several advantages, such as improved coordination and greater success in capturing more formidable or elusive prey.

The social behavior of hunting in groups distinguishes these hawks and demonstrates a level of adaptability that's advantageous in the wild. This characteristic can also be crucial for falconers, as it provides opportunities for observations and understanding of how these birds interact not only with each other but also with the environment.

In contrast, the other characteristics listed do not reflect typical behaviors associated with Parabuteo. For instance, while some birds may be migratory, many Ferruginous Hawks are residents in their habitats without extensive migration patterns. Additionally, although hunting individually can occur, it is not a defining characteristic, as group hunting is more common in these raptors. Lastly, stating they are rarely seen would undermine their status and common sightings in certain areas of North America, particularly in the open habitats they prefer. Thus, the group hunting behavior stands out as a distinctive and advantageous trait for falconers
