The large cactus finch is one of Darwin's finches, a group of closely related birds which evolved on the Galápagos Islands. The group is related to the Tiaris grassquits, which are found in South America and the Caribbean. An ancestral relative of those grassquits arrived on the Galápagos Islands some 2–3 million years ago, and the Española cactus finch is one of the species which evolved from that ancestor.
Some taxonomic authorities, including the International Ornithologists' Union, have split the species from the Española cactus finch. Others still consider them conspecific.Cited works
