finches
Canaries and goldfinches
Finches are small songbirds with stout, conical beaks adapted for cracking seeds.
The family includes hundreds of species—goldfinches, house finches, zebra finches—found worldwide.
Darwin's observations of Galápagos finches, each species with a beak suited to its food source, helped shape evolutionary theory.
Finches are popular as cage birds for their songs and bright plumage.
