The Chinese grosbeak, yellow-billed grosbeak, or black-tailed hawfinch (Eophona migratoria) is a species of finch in the family Fringillidae.^[2]

Subspecies include: ^[3][4]

• Eophona migratoria migratoria (Eastern Siberia, Manchuria and Korea);
• Eophona migratoria sowerbyi( East-central China)

This species is present in Russian Far East, China, Manchuria and Korea. It occurs in forests , mixed woods and bamboo forests of hilly and mountainous areas: it does not fear humans and also goes into gardens and orchards.

Eophona migratoria measures between eighteen and twenty centimeters in length, for a wingspan of 23–24 cm and a weight of 55-60 g. The appearance is massive, as is typical of the finches, with a large head. The beak is very strong and conical. The beak color is yellow (hence the common name of "yellow-billed grosbeak") with a black tip. The body is of a uniform gray color, darker on the back and wings and lighter and tending to silver on the belly, with accentuated brown shades on the sides. The wings are black with a rounded white spot on the tip. The tail is black, the legs of pale flesh color and the eyes are brown. Sexual dimorphism is present. The head mask is gray in the female and not black as in the male.

Eophona migratoria breeds in temperate forests and winters in southern parts of China and Japan, Taiwan and northern Southeast Asia.The nest is cup-shaped and is built by the female among the trees, in the thickest vegetation: inside it usually lays 4 bluish eggs with brown spots, which it hatches alone (with the male who provides it with food) to 12-13 days. The young are fed by both parents and are able to fly around at 12-14 days of age, however they tend to stay with their parents for another 2-3 weeks. Outside the breeding season, this bird tends to live in small groups of about ten individuals, which move among the trees in search of food, rarely going down to the ground. These birds are granivorous, mainly feeding on seeds that they break without problems thanks to the strong and robust beak:. They can feed without problems on other material of vegetable origin (sprouts, berries, fruit), while it is rare to observe them eating food of animal origin (mainly insects).
