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).

Identification:
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.
