Mexico - Los Petenes-Ría Celestún

The ecoregion of "Los Petenes-Ría Celestún" forms a coastal corridor of wetlands in excellent state of preservation. This system forms a unique biogeographical area in Mexico, of great ecological value for its large faunistic and floristic diversity. This region is a mosaic of mudflats, known locally as blanquizales, mixed with mangroves, cattails, reeds, low deciduous forest, low flooded forest, petenes of mangrove and rainforest, medium sub perennial rainforest and coastal dune scrub. This diversity of ecosystems maintains a faunistic diversity representative of the region, among which its avifauna is specially notice worthy, as it is represented by 304 species of birds among residents and migrants, coastal and marsh birds, such as herons (Ardeidae), ducks (Anatidae), gulls (Laridae) and a wealth of migratory songbird species (Passerines) and shorebirds that depart from the neighboring countries to the north of the continent, namely the United States and Canada, during their winter migratory flights.
