Taxonomy

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.[2] 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.[3]

Some taxonomic authorities, including the International Ornithologists' Union, have split the species from the Española cactus finch. Others still consider them conspecific.
