If you mean how can you tell the different species apart, you have to learn/study the different types of hawks available in the world. Different species can be different sizes, different colors, and/or have different proportions (longer/shorter wings, longer/shorter tails, etc.). You just have to learn what to look for, as the first answer says. Get a field guide, that will help.
Males and 1/3 smaller than females. Young(passage) and old have different colors too. For example, a Red Tail Hawk does not have red tail feathers till it is between 9 months and 1 year old. They are usually full grown by 4 to six months. color does not distinguish between sex like other birds. Coopers, Sharp-Shinned, Red Tail, and Red Shoulders all look about the same except for size and and minor color differences. Red Tail is the biggest of those four and Sharp Shinned is the smallest. Find a local Falconer and he can provide all you need to know.
