Abstract: | ABSTRACTThe Caribbean Flamingo (Phoenicopterus ruber) has been a species of conservation concern since the 1960s because of its regional population decline and loss of breeding colonies. In the last two decades, there have been reports of increasing population trends in the Caribbean. The aim of this work is to document the historic population status of flamingos on Margarita Island, Venezuela, and to present an account of their recovery since 2006. In the first half of the twentieth century, flamingos were present on Margarita Island in one location (La Restinga lagoon) in variable numbers (100–800); however, in the 1980s and 1990s, they almost disappeared from the island. In 2006, a group of nine was recorded. During the following years, the population increased in number and expanded eastward on the island. Today, the population size range 1 600–2 000 individuals, are present regularly in at least eight lagoons, and two breeding colonies have been reported. Several threats are still present in the island that can revert the positive population trend. The recovery of the population in Margarita Island is a consequence of successful regional conservation efforts and the maintenance of wetlands with appropriate conditions for the species, particularly in protected areas. |
