인터넷 검색으로 찾은 암수 차이, 거의 구별이 어렵다는 말씀~

Common myna bird males and females look alike. They have no external features that distinguish gender. Adult males are slightly larger, and their wattles, or skin flaps on their necks, are a bit longer. Males typically are bolder. The distance between the pelvic bones is wider in adult males than in females -- not that you could tell that from casual observation. Juvenile males and females are identical in appearance.

The only surefire ways to determine whether a common myna is male or female are surgical sexing procedures or DNA sexing sourced from feathers, blood or eggshells.
