What characteristic does the Peregrine Falcon demonstrate when comparing males and females?

The Peregrine Falcon exhibits sexual dimorphism, which means there are noticeable differences between males and females, particularly in size. In this species, females are typically larger than males. This size difference is a common trait among many raptors, where the female is larger to accommodate reproduction and egg-laying. The female's greater body mass provides her with the necessary strength and energy reserves to care for her young.

Understanding the size difference is crucial for falconers and bird watchers alike, as it can help in identifying the gender of these magnificent birds during observation or training. The other characteristics mentioned, such as males being smaller or differences in wing length, do not apply to the Peregrine Falcon in the same way, as the marked size difference is a defining characteristic of this species.
