GROSBEAK (Fr. Grosbec) , a name very indefinitely applied to many birds belonging to the families Fringillidae and Ploceidae of modern ornithologists, and perhaps to some members of the Emberizidae and Tanagridae, but always to birds distinguished by the great size of their bill. Taken alone it is commonly a synonym of hawfinch (q.v.) , but a prefix is usually added to indicate the species, as pine-grosbeak, cardinal-grosbeak and the like.

The hen is not so good a songster as the cock bird. Her plumage, with exception of the wings and tail, which are of a dull red, is light-olive above and brownish-yellow beneath. This species inhabits the eastern parts of the United States southward of 40° N. lat., and also occurs in the Bermudas. It is represented in the south-west of North America by other forms that by some writers are deemed species, and in the northern parts of South America by the C. phoeniceus, which would really seem entitled to distinction.

In structure and some of its habits much resembling a bullfinch, but much exceeding that bird in size, it has the plumage of a crossbill and appears to undergo the same changes as do the members of the restricted genus Loxia—the young being of a dull greenish-grey streaked with brownish-black, the adult hens tinged with golden-green, and the cocks glowing with crimson-red on nearly all the body-feathers, this last colour being replaced after moulting in confinement by bright yellow.
