A wide representation of Cuban and international fauna is present in the Great Northern Wetland of Ciego de Avila, the second largest and most important in the country, particularly species of birds, reptiles and mammals that find in this ecosystem an ideal refuge as winter or permanent residents.

Among the most important specimens are bats, with approximately 20 of the 26 species reported in the country.

There is also a subspecies of blue lizard, exclusive to the northern cay of Ciego de Avila, as well as numerous migratory and native birds, including the marsh cabrerito.

There are also the white ibis and the Cuban crane, the largest bird in the Cuban archipelago.

As well as being a refuge for numerous species, this ecosystem constitutes one of the most important barriers against the impact of extreme meteorological phenomena such as hurricanes of great intensity. (Redacción Informativa R.M)
