Beak of Finch

The thing that surprised me the most while reading the book was the diversity of finches. There are about a dozen different species of finches, each with their own distinct traits and characteristics from the size of their beaks to their feathers. They are in a secluded area so their mating and reproductive processes are limited, but within their small area they are able to create new species. But their environment doesn't stop them from mating all the time. The island is filled with different foods and new species, so it creates this exotic area/environment. the finches really do exercise Darwinism, survival of the fittest, because they are able to adapt so easily, thus they are able to compete. Their distinct characteristics not only allow us to tell them apart, but also help them do what they do best! Like the hummingbirds's beak allows it to sing and tear apart wood whereas a pelican's beak helps it filter water.
