The reasons why munia are more expensive than guineas:

1. The difficulty of raising munia is relatively low. Pearl birds are more sensitive to the cold than munias and are more troublesome to maintain, so more people like to raise munias.

2. The reproduction speed of munia and the survival rate of young birds are much higher than that of guinea birds. Munias can reproduce in the three seasons of spring, autumn and winter, and the survival rate of young birds is still very high. Guinea birds only breed in spring and summer, and the survival rate of young birds is not high.

3. The training difficulty of munnia is low, so there are more people raising munnia. The guinea bird is timid and easily frightened, and its ability to adapt to the environment is weaker than that of the munia.

The difference between the white guinea bird and the white guinea bird:

1. The white guinea bird is as big as a sparrow; the white guinea bird is as big as ten sisters.

2. The beak of the White Munia is proportionally larger than that of the White Pearl. There is little difference in the color of the male and female White Munia's beaks. There is a difference in the color of the male and female White Pearl's beaks. The male bird is pepper red and the female bird is orange red.

3. The calls of the White Munia and the White Pearl Bird are different. The White Pearl Bird can chirp, but the White Pearl Bird cannot.

4. The tail of the White Munia is long, and the body is long and streamlined; the White Pearl Bird has a relatively large head, and the body is short and round rather than slender.
