Which species of raptor does not exhibit sexual dimorphism?

Sexual dimorphism refers to the differences in physical characteristics between males and females of the same species. In many raptor species, females tend to be larger than males, which is a common trend in birds of prey due to their reproductive roles.

The answer stating that none of the options are correct implies that all the listed species exhibit sexual dimorphism. In fact, kestrels, red-tailed hawks, and peregrines do show some degree of sexual dimorphism. For example, female kestrels are generally larger than males, and the same pattern can be observed in red-tailed hawks and peregrine falcons, where females are more robust and have different physical features compared to males.

Understanding these traits is important for bird identification and can influence behaviors, such as hunting strategies and mating. Recognizing that all the species listed display sexual dimorphism clarifies the context of the question and reinforces the significance of size and physical characteristics in raptor identification.
