Alfred Newton, 1911 Encyclopædia Britannica, Volume 12… (1911)
“ 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. ”
