Why are females more powerful and larger than males in certain species while in others they are smaller and weaker?
In: Biology
In birds of prey, the female is often larger. She has greater energy expenditure, producing and laying eggs and all, so she’s bigger. With the male being smaller, the pair hunt for different strata/size of prey. So when they hunt to feed the chicks they are not directly competing for the resources, and can each bring back food.
