Grosbeak is the name given to a form taxon containing several species of seed-eating passerine birds with large beaks. Although they all belong to the superfamily Passeroidea, they are not a natural group but rather a polyphyletic assemblage of distantly related songbirds.
The following is a list of grosbeak species, arranged in groups of closely related genera. Note that these genera are more closely related to smaller-billed birds than to other grosbeaks. The single exception are the three genera of "typical grosbeak finches", which indeed form a group of closest living relatives and might thus be considered the "true" grosbeaks.
Typical grosbeak finches
Two species in the genus Serinus are named "Grosbeak-canaries": the Abyssinian Grosbeak-canary (Serinus donaldsoni) and the Southern Grosbeak-canary or Kenya Grosbeak-canary (Serinus buchanani). The genus Serinus is somewhat closely related to the golden-winged grosbeaks.
In addition, there are two extinct Fringillidae "grosbeaks": the Bonin Grosbeak (Chaunoproctus ferreorostris), found only on the Ogasawara Islands, which was last recorded in 1832, and the Kona Grosbeak or Grosbeak Finch (Chloridops kona), a Hawaiian honeycreeper, last recorded in 1896.
