Mustelirallus cerverai
The Zapata Rail, Mustelirallus cerverai, is one of the world's most enigmatic and critically endangered birds, endemic to a tiny portion of Cuba. This medium-sized rail, measuring approximately 29 cm (11.4 in) in length, is characterized by its dull olive-brown upperparts, dark grey underparts, and striking bright red eyes. Its most distinctive field marks include its stocky build, short tail, stout yellowish bill, and the absence of significant sexual dimorphism. Taxonomically, it belongs to...
This rail exclusively inhabits dense, flooded sawgrass (Cladium jamaicense) marshes at very low elevations, often just above sea level.
Its diet consists mainly of invertebrates, including snails, insects, and small crustaceans, supplemented with some plant material. It forages by probing the mud and vegetation.
The Zapata Rail is notoriously secretive and largely diurnal, though its elusive nature makes comprehensive study challenging. It primarily forages by probing through the dense vegetation and shallow water, often on the floating mats of sawgrass. While specific territorial behaviors are poorly do...
The Zapata Rail is strictly endemic to a critically small area within the Zapata Swamp in the Matanzas Province of Cuba. Its entire known distribution is confined to the dense, flooded sawgrass marshes, primarily around the Santo Tomás and Peralta regions. As a flightless species, there is no bre...
