The Caribbean flamingo is the most brightly colored flamingo out of the 6 flamingo species. Flamingos are known for their long legs and neck, and they are usually 3-4 feet tall. They have an unusual shaped beak that is useful for feeding on plankton, tiny fish, and small crustaceans. The color of the flamingo actually depends on the type of food eaten. For example, Caribbean flamingos tend to be far paler in the wild than birds in zoological collections, since they feed on high quality, specially manufactured zoo.
