In most raptors, which sex is larger?

• A. Male
• B. Female
• C. Both equally large
• D. Size varies by species

Answer: (B)

Raptors show reverse sexual dimorphism, meaning females are typically larger than males. This size difference has advantages: a bigger female can incubate and defend the nest more effectively and handle larger prey to feed herself and the chicks, while a smaller male maintains greater agility and speed for efficiently catching smaller prey and delivering food. The result is a practical division of roles that often reduces direct competition for food between the sexes. While there are exceptions, in the majority of raptor species the female is the larger bird.
