Zoo staff performed the surveys at Lake Catherine on the island of West Caicos. This island has an area of just 9 square miles and is relatively undisturbed by humans. It is ideal for flamingo nesting due to the absence of large predators. Lake Catherine is an inland saltwater lake that has been claimed as a nature preserve, keeping it safe from further disturbances. Zoo staff concluded that the lake is being used for feeding and roosting by a group of Caribbean flamingos believed to be migrating from a large nesting site on the island of Anauga. In 2009, staff located more than 100 birds. In 2010, there were 75 to 80. No active nests were found, but the biologists did find areas for possible nesting
