Although three species of wrens have been recorded on the main island of Cuba, just one species, the globally threatened Zapata Wren, breeds there, with the other two being known solely as vagrants. This species is confined to the world-famous Zapata Swamp, on the island’s south coast, where its population is small and the birds can be difficult to find, although like most New World wrens, they can be reasonably easy to hear. It is a relatively weak flier, and the birds usually move low down through the dense sawgrass vegetation that characterizes their habitat, although scattered bushes are required for nesting. Principally brown above and below, the Zapata Wren is barred blackish above, and paler below, and has a long tail, held downards, and a reasonably long and slightly decurved bill. This wren is one of three endemics named for the swamp of the same name, two of which (including the wren and the rail) were discovered in the late 1920s by the Spanish soldier and naturalist Fermín Cervera, who is commemorated in both the generic and specific names of this species.
