Darwin was interested in the finches! The finches weren't interested in him!

All known species of Darwin's Finches are found on the Galápagos islands. With the exception of one, the Cocos Finch, which is found on the Cocos Island.

Darwin's finches are not actually true finches. Darwin knew they weren't finches, but an ornithologist called Percy Lowe, later in 1936 incorrectly called them "Darwin's Finches" in a book, a term which unfortunately stuck.

Charles Darwin discover the finches in Galapagos in 1831. He noticed that the finches beaks were different compared to the finch's in Ecuador.
