User: What is sexual dimorphism? What types of animals exhibit it?

Weegy: Sexual dimorphism is a physical difference in appearance between males and females of the same species. Many hawk species exhibit sexual dimorphism in their size. Typically, the male is much smaller than the female (sometimes half her size). Check out this picture: http://www.allaboutbirds.org/guide/PHOTO/MED/gambels_quail_3.jpg The male quail (right) looks different from the female (left). Another examples is in peafowl. Peahens don't exhibit the same extravagant tail feathers that the males do. Some animals are not sexually dimorphic and there is no way for a human to tell them apart without examining sexual organs or doing a blood test. One example of this is the screech owl. Also, most parrot species are not sexually dimorphic (with a few exceptions).
