Macaws live in rainforests. Their main sources of food are nuts, leaves, berries, and seeds. A macaw has a strong, hooked beak for breaking into nuts and seeds and ripping tough leaves apart. As temperatures increase due to climate change, tropics will have dryer conditions and reduced rainfall. The Amazon could degrade into a savanna in less than 50 years, changing the availability of the foods that the macaw eats. Birds that live in a savanna biome eat mainly insects and some seeds. These birds tend to have thin, slender, pointed beaks for picking insects off of twigs and bark. The macaw’s beak would adapt to have a strong, wider top, with a thin front to be able to break into seeds and make precise movements to catch small insects. Another adaptation that would occur is a change in the color of their feathers to camouflage within their new surroundings.
