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).
Plumage characteristics similar to the ground finches and Cactus finch. ADULT MALE: Wholly black with white-tipped undertail-coverts. FEMALE / IMMATURE: Dull black or dark grey, often with faint white fringes to the feathers on the underparts.
