Description
Illustration from page 379, Journal of Researches" 2nd Edition 1845 Charles Darwin. The contrasting beaks of four Galapagos finches, three Geospizinae genus and one Certhidea (Warbler finch). Darwin originally misidentified the finches when he collected them on the Galapagos, assuming them to be from very different groups. He also failed to label them well, which he always regretted. Artist/ornithologist John Gould identified them for him and alerted him to them as a new group of 12 closely related species of ground finch (actually members of the Tanager family, Thraupidae). The name 'Darwin's finch' was applied by Percy Lowe in 1936. The finches were famously studied by David Lack in the 1940's and more recently by Peter and Rosemary Grant. The Grants provided the best evidence of evolution within a human time-frame with finches found on Galapagos' Daphne major and minor islands."
