Which birds are mentioned as prime examples of the falcon family?

The American kestrel and merlin are indeed prime examples of the falcon family, scientifically classified under the family Falconidae. These birds are small, agile, and known for their remarkable hunting skills, characteristics typical of falcons. The American kestrel is recognized for its vibrant plumage and ability to hover in place while hunting. The merlin is a small but powerful falcon that exhibits incredible speed and aggression when pursuing prey, embodying the falcon's predatory prowess.

On the other hand, the other groups of birds listed do not belong to the falcon family. Ferruginous hawks and red-tailed hawks are part of the Accipitridae family, encompassing many types of hawks and eagles. Goshawks and sharp-shinned hawks also fall under Accipitridae and are known for their forest hunting techniques. Ospreys and ibises represent entirely different families; ospreys belong to Pandionidae and are specialized fish hunters, while ibises are wading birds from the Threskiornithidae family. Thus, B stands out as the correct choice highlighting members of the falcon family.
