Blue and yellow macaws are found in Panama and throughout the northern regions of South America. They live in less dense rainforests and prefer to make their nests in hollowed trees. They can also be found near swamps or rivers and in palm trees. Blue and yellow macaws are herbivores. They eat a variety of fruits, nuts and seeds. They especially enjoy seeds from the Hura crepitans tree. Blue and yellow macaws congregate together in very large flocks with as many as 100 or more birds. Early in the mornings, they fly as a group in search of food.
