How Do Birds Survive the Winter?

In adaptive radiation, many different species evolve from a single ancestor species. Each new species evolves to exploit a different niche, such as food source. In the example above, Hawaiian honeycreepers evolved a range of bill forms in response to available food sources on the Hawaiian archipelago. Illustration by Jillian Ditner, photo by Ashlyn Gehrett.
