|Zapata Wren (Ferminia cerverai)
The Zapata Wren is found only in the Zapata Swamp of Cuba where it is even then confined to a small part of the area. It inhabits marsh with seasonally flooded sawgrass.
It has a long tail and bill and is brown with black barring above and browny-white below. Like most wrens it is a skulker which, added to its preferred habitat, makes it quite difficult to see.
It is classified as Endangered by Birdlife International who have an excellent page on this species here.
