One way to accurately determine the sex of a bald eagle is through genetic testing or molecular sexing, which involves analyzing the bird's DNA to identify specific genetic markers that differentiate between males and females.
How can you identify the sex of a bald eagle?
You cannot reliably determine the sex of bald eagles based on physical characteristics such as size or appearance unless you compare two individuals side by side: females tend to be slightly larger than males. Other than that, both adult female and male bald eagles have similar size, coloring, markings, and vocalizations.
