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 but bill rather distinctive, being long and pointed and appearing slightly decurved. ADULT MALE: Wholly black with white-tipped undertail-coverts. FEMALE / IMMATURE: Brown and heavily streaked, particularly around the head and neck.
