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.

Charles Darwin discovered over 100 species of birds on the island.

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]
