How many species of finch are in the Galapagos?

There are 13 recognized species of finches in the Galápagos Islands, often referred to as Darwin's finches. These species vary in size, shape, and feeding habits, which have evolved to adapt to the different ecological niches on the islands. Their diversity is a key example of adaptive radiation, illustrating how species can evolve from a common ancestor in response to environmental pressures.
