How can you tell the difference between a female and male bald eagle?

The birds look the same, but the female is somewhat larger.

A female has larger breasts and no penis. A male has a penis and smaller breasts.

Human Beings The difference is that the boy has a penis and an Adams Apple. Girls have no Adams apple and when going through puberty girls get a period for which they have to use tampons or pads.

That depends entirely on the species.

Females are bigger then males and have an "eye shadow" around their eyes.
