Darwin Finches, or Galapagos Finches, are small land birds with generally dull black, brown or olive, often streaky, plumage; short tails; and short, rounded wings. Their bills vary greatly in size and shape (a fact which was instrumental in inspiring Charles Darwin's thinking in relation to the theory of evolution - and hence the name given to this fascinating group of species).
Very similar to Small Ground Finch but bill longer and more pointed, the culmen being less curved. ADULT MALE: Wholly black with rufous undertail-coverts. FEMALE / IMMATURE: Generally darker than the other species of ground finch.
