Excuse me, experts, may two turtledoves hatched in the same nest be a female and a male?

(1) Male and female identification of young birds before singing: first look at the body. The big embryo is a male and the small one is a female. Second, look at the shape of the head. The male bird has a big flat head, and the female bird has a small round head. Third, look at the shape of the mouth, the elderly with thick mouth are men, the thin mouth is women, and the short mouth is women. The fourth is to look at the color of the mouth and legs. The male bird's mouth is jade white and his legs are flesh red; The female's mouth and legs are gray. According to the above morphological characteristics, we can identify the male and female of myna young black.

(2) Male and female identification of adult birds is mainly listening to songs. The second is the difference in form. The male bird's song is beautiful and passionate, while the female bird's song is low and not very pleasant. The feather color of adult birds is the same as that of females, but from the morphological point of view, the male bird's head is big and slightly flat, the mouth is slightly thick and long, showing white jade color, and the legs are red or yellow. The female bird has a small round head, a thin and slightly short mouth, gray, and gray or light yellow legs. From the cloaca, there are obvious differences between male and female birds outside the cloaca. The cloaca of the female bird is slightly flatter than that of the male bird, and there is a loose circle of small feathers around it. The cloaca of a male bird is a small cylindrical protrusion with a string of feathers at the top. Experienced bird people can judge the sex of an adult or young bird only from the flat protrusion of the cloaca.
