Reply To: What are Finches
Finches (True Finches or Fringillids) are the birds of the family Fringillidae of the order Passeriformes (perching birds) belonging to the class Aves (birds) of the phylum Chordata (chordates) of the kingdom Animalia (animals). Finches are small sparrow-like seed-eating birds having an almost world-wide distribution; spanning over Africa, Eurasia, North America, and South America.
Finches are generally characterized by their short, thick and conical beaks / bills, especially adapted for eating seeds. Finches are separated from other seed-eating birds (seedeaters) by the reduction of the 10th primary feather and by the presence of grooves at the edge of the horny palate. The grooves are used to wedge the seeds in the beak, and then, husks are removed from the seeds (dehusking of seeds) with the tongue.
The examples of finches include the house finch, goldfinch, chaffinch, bullfinch, canary, koa-finch, rosefinch, and many others.
