Flamingos are pink or red. This is because of small bacteria that live in water which the flamingos eat. They also eat small crayfish and algae. Baby flamingos are gray. Flamingos can fly. This is why they have wings. Flamingos are very tall birds and they have long legs. They often stand on only one leg. Scientsts found that they do this beacuse it takes less energy than standing on two legs. Flamingos have a curved bill that is shaped like a banana. This is because they feed in the mud on the bottom of lakes.
