Darwin's "finches" represent a remarkable series of species that inhabit the
Galápagos and Cocos Islands. They have diverged from the original
colonizing species to give rise to around 15 species in four genera.
They differ in their morphology and habits.
Darwin did not recognize their common origin, but was rather informed of this
fact by his colleague John Gould.
Years ago, I experienced a bit of a revelation in learning that Darwin's
"finches" are no longer classified as true finches, but rather as tanagers!
- in the family Thraupidae.
