Anegada is also known for the large salt ponds that cover much of the west end of the island, These ponds, which support unique fauna, were designated a Ramsar Site on 11 May 1999. In the 1830s, thousands of Caribbean flamingos lived in these ponds, but they were hunted for food and feathers throughout the 19th and early 20th centuries and disappeared by 1950. They have been reestablished. As of 2016, the flamingo flock numbers approximately 200 birds. The birds are another tourist draw, but officials are trying to keep the number of visitors to the flamingo areas at a level that allows the birds to flourish. The western salt ponds and south-eastern coastal mangroves have been recognised as an Important Bird Area (IBA) by BirdLife International.
