Which statement is true regarding the tail of the Peregrine Falcon?

The statement that the tail of the Peregrine Falcon is proportionally shorter than that of the Prairie Falcon is accurate based on the distinctions between these two species. Proportional tail length is an important characteristic that can help in identifying different falcon species. The tail of the Peregrine Falcon, while still long and adapted for speed, has a particular shape and length that differs when compared to the Prairie Falcon, which has a notably longer tail in relation to its body size.

This difference in tail proportion can affect a falcon's flight dynamics and maneuverability in the air. The Prairie Falcon, with its longer tail, is well-suited for its hunting style that includes agile aerial displays in open spaces, while the Peregrine Falcon relies on its exceptional speed, largely facilitated by its body shape and tail structure.

Understanding these anatomical differences is crucial for falconers and bird enthusiasts to accurately identify bird species and comprehend their behavioral adaptations.
