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.
They had descended with modification from a common mainland ancestor.
Darwin was puzzled about the many adaptations of the finches on the Galapagos Islands

right
Since Darwin found many species of plants he found many species of finches. Those species, just like the warbler finch, were found on the Galapagos Islands.
By adaptive radiation. The original finch emigrated to the Galapagos Islands and found many different environments and feeding opportunities per individual Island. So, under this new selection pressure and the random mutational variation all species have, many new species of finch arose on all the various Islands of the Galapagos.

Geographic IsolationSpeciation in the Galápagos finches occurred by founding of new populations, geographic isolation, gene pool changes, reproductive isolation, and ecological competition.
