Bird Conservation Region 56

Planicie de la Península de Yucatán

This BCR covers most of the Yucatan Peninsula, including parts of Campeche and Quintana Roo and all of Yucatán. Calakmul is an IBA and biosphere reserve located at the highest elevations of the Campeche Plains. There are no major watercourses in the area, but rather surface pools, locally known as “aguadas,” where water collects in natural depressions. Tropical semi-deciduous and deciduous forests, tropical rainforest, and aquatic vegetation predominate. This is the largest reserve in the Mexican tropics, sheltering an avifauna that includes 118 protected species and nine that are endemic to the region. Important among these are Harpy Eagle, King Vulture, Emerald Toucanet, Wood Stork, Jabiru, Muscovy Duck, Masked Duck, and Spectacled Owl. Mesoamerican endemics include Ocellated Turkey, Yellow-lored Parrot, Rose-throated Tanager, Red-vented Woodpecker, Orange Oriole, Yucatan Flycatcher, Yucatan Jay, and Yucatan Poorwill. Sierra de Ticul–Punto Put is an IBA at the point of convergence of the states of Campeche, Yucatán, and Quintana Roo. It is adjacent to Calakmul and has similar vegetation. Additional important species in this IBA include Common Black-Hawk, Great Curassow, Crested Guan, Yellow-headed Vulture, Bat Falcon, Limpkin, and wintering Hooded and Swainson’s Warblers. Sian Ka’an IBA is also a biosphere reserve. It is located in coastal Quintana Roo and features a wide variety of habitat types, including tropical rainforest sloping down to the sea, flooded rainforests, freshwater and brackish swamps, coastal lagoons, and keys. Additional important species here include Rose-throated Tanager and Buff-bellied Hummingbird. This BCR also includes the Ría Lagartos Biosphere Reserve, where nesting Greater Flamingos are found.
