Anna's hummingbird, from the tropical rainforest, has adapted to the environment but may adapt more in the future. They have a long beak that helps them to reach into tubular flowers to get nectar. Their heart rate goes up to 1,250 times per minute so that oxygen gets to the muscles for the fast flapping wings. They have eyes on the side of their head, water repellant wings, muscles that allow them to fly forward and backward, and reproductive organs that shrink to make them lighter. In the future they will adapt to have four wings and a skinnier body to fly faster to escape predators. Longer beaks will be important to reach more pollen in case there are less flowers in the rainforest. The coloring is the same but will be camouflaged. Anna’s hummingbirds are amazing animals but in the future they will be more amazing!
