The Galápagos Finches
One of the most important kinds of animals found there are the Galápagos finches, also called Darwin's Finches.
For more than 30 years, scientists have been studying the populations of finches and their ecosystem on one very tiny island: Daphne Major. The island is small enough that the scientists have been able to directly observe a large proportion of the birds that live on the island.
