The birds Darwin found in the Galapagos were different types of finches, not separate types of birds led Darwin to develop his theories on adaptation.
Further Explanation:
When Darwin collected many specimens of finches from three islands, it was seen that his collection was closely related group of distinct species. All finches were similar to one another except for their beaks. Those finches radiated from a single species that colonized the Galapagos.
Darwin finches suggest that they are descendants from a single species. Their ancestors appeared on Galapagos and evolved into different species relating to the beak shape, body size, and size, feeding behavior etc. Darwin finches colonized the Galapagos Island. Their species evolved and move to different habitats which best suits their lifestyle. Darwin concluded that birds adapt to their environment in order to survive on available food and to best suit their lifestyle.
Darwin finches migrate to Galapagos Island and they evolved from a common ancestor into 15 different species. Darwin finches had diversified and adapted to eat different foods.
