They have long legs. Males are usually slightly larger than females. All of them have a long bill that is flattened at the tip like a spoon. Their bills are black in colour when they are adults. A little bit of red colour appear in their lower bill when they are subadults. They have yellow flecks when they are ten years old or above.
