3 Darwin’s Finches on Rábida Island in Galápagos, EC

Rábida Island is home to nine of the 14 finch species endemic to the Galápagos. They are collectively called Darwin’s finches because they contributed to Charles Darwin’s theory of evolution. He collected bird specimens during his five weeks in the Galápagos in 1835. But he was unaware of their genetic differences until 1837 when John Gould from the Zoological Society of London identified 12 unique types of finches. Each species had adapted to the conditions of their habitat. This is a female common cactus finch. The ground bird’s name stems from its propensity to feed on prickly pear cactus (Opuntia). The Geospiza scandens is found on 13 islands in the Galápagos.
