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).
Similar in size to Large Tree Finch but bill is smaller and less parrot-like. The tips & mandibles do not cross. ADULT MALE: Head, neck, breast and mantle black when fully mature, the remainder of the upperparts being olive-grey with some dark streaking. Underparts pale, often with a yellow tinge. FEMALE / IMMATURE: Upperparts olive-grown with faint streaking. Underparts paler and virtually unstreaked.
