Española cactus finch
species of bird

The Española cactus finch (Geospiza conirostris) is a species of bird in the tanager family Thraupidae. It is one of Darwin's finches, and is endemic to the Galápagos islands, where it is restricted to Española, Genovesa, and the Darwin and Wolf Islands. This rather dark bird resembles the smaller and finer-beaked common cactus finch, but the two species do not co-inhabit any island.
Its natural habitat is dry shrubland and it is commonly seen on the ground. Its main food source is the cactus Opuntia.
Taxonomy
The Española cactus finch is one of Darwin's finches, a group of closely related birds that 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 that evolved from that ancestor.
From a study done in 2015, the Española cactus finch of Española was found to be a sister to the large ground finch, not to the Genovesa cactus finch. The International Ornithologists' Union has changed the taxonomy based on the study.
This brief starts where responsible research should: with the source description of “Española cactus finch” as species of bird. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of bird. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Apr 13, 2026. The linked authority identifier is Q843364. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2015.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
