The seedeaters are a form taxon of seed-eating passerine birds with a distinctively conical bill.

Most are Central and South American birds that were formerly placed in the American sparrow family (Emberizidae), but are now known to be tanagers (Thraupidae) closely related to Darwins finches. Indeed, some of these seedeaters are closer to these, while the more "true" seedeaters form a clade with certain tanagers. A few "atypical" seedeaters are closely related to a number of tanagers, many of which (such as the flowerpiercers) have peculiarly adapted bills.

In addition, there are some Africam passerines called seedeaters. They belong to the serin genus (Serinus) of the true finch family (Fringillidae), but might warrant to be separated with their closest relatives in Crithagra.

American seedeaters

Male Variable Seedeater (Sporophila corvina), a true seedeater from the tropical Americas

True seedeaters

  • Amaurospiza – blue seedeaters (4 species, tentatively placed here)
  • Dolospingus – White-naped Seedeater
  • Oryzoborus – seed-finches (6 species, sometimes included in Sporophila)
  • Sporophila – typical seedeaters (some 30 species, 1 possibly recently extinct)

Related to Darwin's finches

The Plain-coloured Seedeater (Catamenia inornata) is less close to the true seedeaters than to other tanagers
