The male and female of the hemp bird can be distinguished by the following methods:
Observe the head: The head of the male hemp bird is relatively large, with a pronounced back of the head and a wide lower forehead. The female has a relatively small head, no back of the head, and a narrow lower forehead.
Observe the eyes: The eyes of the male are attentive and close to the corners of the mouth, while the eyes of the female are relatively dull and far from the corners of the mouth.
Observe the eyebrows: the eyebrows of the male flax bird are more delicate, while the eyebrows of the female hemp bird are thicker and shorter, and some places are not coherent.
Observe the legs: The legs of the male are thicker and longer, while the legs of the female are thinner and shorter.
Observe the beak: The beak of the male is long and thick, while the beak of the female is short and thin.
Observe the wings: the wings of the male are generally shiny, while the wings of the female are relatively dull.
Observe the collar: the black collar is longer but not shiny for male, while the black collar is shorter and shiny for female.
Observe the oral cavity: the oral cavity is red for male, and the color red with yellow is female.
Observe the degree of head stiffness: when holding the sparrow with your hand, it is the male bird who has its head forward and does not shrink back, while the female bird has her head tilted back.
Observe the level of activity: male sparrows are more active and often active in the nest, while female birds are more docile.
In addition to the above methods, you can also distinguish the male and female of the hemp bird by touch. Specifically, you can touch the butt of the hemp bird, if it is a bulging male, if it is a mediocre female.
In conclusion, distinguishing between male and female flax birds requires observation and judgment from many aspects.
