Which description qualifies as a falcon?

The description that qualifies as a falcon hinges on the specific characteristics and classifications of these birds. The correct choice includes both the identification of a specific female of the species, Falco peregrinus, which is one of the most recognized falcon species, and the broader classification that encompasses the shared physical traits common among falcons.

Falcons are defined by their unique morphology, which typically includes long, pointed wings, long tails, small heads, and broad shoulders. The inclusion of this description helps in understanding what makes a falcon distinct from other raptors, such as eagles and hawks, which may have different physical characteristics.

While any bird used in falconry encompasses a wide variety of birds, it does not specifically target the defining traits of the falcon family. Therefore, while all falcons may be used in falconry, not all birds used in falconry are necessarily falcons. This distinction underscores the importance of precise identification based on taxonomic classification and physical attributes rather than broader usage in falconry.

Option D captures the essence of what qualifies as a falcon by combining the specific species with the general characteristics, while excluding the broader and less precise definition associated with falconry use.
