Female bald eagles are larger than their male counterparts by roughly a third in size. Females tend to have a body length of 35 to 37 inches, while males tend to be 30 to 34 inches long.
Both male and female eagles have four talons--three in front and one in back. The back-facing talon or hallux tends to be longer on female bald eagles.
Thanks, but that is not very relevant when you are only looking at one eagle at a time.
