Higher reproductive success of small males and greater recruitment of large females could explain the strong reversed sexual dimorphism (RSD) in the northern goshawk

Abstract Reversed sexual dimorphism (RSD), whichoccurs when the female of a species is larger than the male,is the rule for most birds of prey but the exception amongother bird and mammal species. The selective pressuresthat favour RSD are an intriguing issue in animal ecology.Despite the large numb...
