First graders at Bellew recently investigated the science of animal adaptation and why birds have beaks. After learning about different types of beaks, and watching a video showing birds eating in their natural habitats, the students tested which was the best beak for eating by picking up different types of “bird food” with straw tweezers. They discovered that a long, thin hummingbird-shaped beak could only extract food from a liquid, such as nectar. A duck, which has a wide, flat beak, can easily eat seeds, rocks and fish.
