Darwin’s Finches

A concise write-up on this subject is found at J. Kimball’s Biology Page. It gives a drawing containing sketches of 13 finch species. The species names are:

  1. Large cactus finch (Geospiza conirostris)
  2. Large ground finch (Geospiza magnirostris)
  3. Medium ground finch (Geospiza fortis)
  4. Cactus finch (Geospiza scandens)
  5. Sharp-beaked ground finch (Geospiza difficilis)
  6. Small ground finch (Geospiza fuliginosa)
  7. Woodpecker finch (Cactospiza pallida)
  8. Vegetarian tree finch (Platispiza crassirostris)
  9. Medium tree finch (Camarhynchus pauper)
  10. Large tree finch (Camarhynchus psittacula)
    [last two found later on in the same page]
  11. Small tree finch (Camarhynchus parvulus)
  12. Warbler finch (Certhidia olivacia)
  13. Mangrove finch (Cactospiza heliobates)

Darwin originally mistook these finches for grosbeaks. Drawing reproduced below
