Seedeater

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

For seed-eating animals in general, see Seed predation.

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

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

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-colored seedeater (Catamenia inornata) is more closely related to other tanagers than to the true seedeaters
