The seeds shifted from large, hard to crack seeds to many different types of small, softer seeds. 9 min read. [14], Big Bird was originally assumed to be an immigrant from the island of Santa Cruz. the outcome was a lack of small seeds- small beaked finches ate/eat small seeds so most of those finches were killed off.

Today the different species of finches on the island have distinct habitats, diets, and behaviors, but the mechanisms involved in speciation continue to operate. But because the two peaks are so close together, and there is no room for them to widen farther apart, random mating brings the birds back together again.
