Not far out of Puerto Villamil there are various salt and brackish lagoons which house an impressive variety of coastal and sea birds. Flamingos are not endemic to Galapagos, but these beautiful pink birds are still a favourite. Flamingos eat certain tiny crustaceans that live in the brackish salty water. There are only a handful of places in Galapagos that meet the requirements for their very specific food, so there are never more than a few hundred flamingos in Galapagos at any time. They do nest and breed in the islands, so it is possible to see young ones at certain times of the year. Flamingo Lagoon is a must-see for visitors when visiting Isabela Island.
