Vampire Finch

The Galapagos Island is known because of Darwin's theory of evolution. He studied many animals during his travels and mainly had interest in finches. The finches of the Galapagos Islands are known as Darwin's Finches. He discovered that the size and shape of the finches beaks determined what they ate and ultimately discovered his theory of natural selection. The different islands had different food sources and the finches adapted to the most abundant food source available to them.


The Vampire Finch is a subspecies of one of Darwin's finches, the Geospiza difficilis. Geospiza difficilis is translated into sharp-beaked ground finch. The only difference in the vampire finches is their dietary preference. They are referred to as the vampire finch because they drink the blood of seabirds during dry periods. The vampire finch can only be found on Wolf and Darwin Island in the Galapagos Islands.
