This list of birds recorded in the Galápagos Islands includes species recorded in the Galápagos Islands of Ecuador, where 189 species have been documented as of May 2024. [1] Of them, 31 are endemic, three nest only in the Galápagos, and virtually the entire population of a fourth nests there. Seventeen endemic subspecies are noted.
Birdlife International defines Endemic Bird Areas (EBAs) as places where the breeding ranges of two or more range-restricted species—those with breeding ranges of less than 50,000 km 2 (19,000 sq mi)—overlap. In order to qualify, the whole of the breeding range of at least two range-restricted species must fall entirely within the EBA. [1]
The fauna of the Galápagos Islands include a total of 9,000 confirmed species. Of them, none have been introduced by humans, and seventeen are endemic. [citation needed] Due to amphibians intolerance of saltwater, no amphibians naturally occur on the Galapagos Islands.
The Galápagos penguin is a particularly vulnerable bird species due to its limited range on the Galápagos Islands. With a population of only about 1800, it remains on the endangered species list, and its population will likely fluctuate strongly in response to anthropogenic changes in the region. [26]
On the other hand, there are many mammal species, mostly sea mammals such as whales, dolphins and sea lions. A few species of endemic Galápagos mice (or rice rats) — the Santiago Galápagos mouse and the Fernandina Galápagos mouse — have also been recently rediscovered. Charles Darwin discovered over 100 species of birds on the island.

The small ground 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] When Charles Darwin first collected the species in 1835, he thought it was a finch.
