During Charles Darwin’s five week visit to the Galápagos Islands in 1845, he noticed finches varied by island. Two years after he returned to London, it was confirmed these small birds had evolved into distinct sub-species. The most notably difference is the shape of their beaks based on available food. This finding helped support Darwin’s theory of evolution. There are 15 types of finches in the Galápagos This is a large tree finch. Its scientific name is Camarhynchus psittacula.
