Zapata Rail
Cyanolimnas cerverai · also called Zapata rails
Glimpsed so rarely that researchers have sometimes gone decades between confirmed sightings, a Zapata rail survives only within a single Cuban swamp, a nearly flightless bird whose entire existence depends on one fragile stretch of wetland.
Overview
The Zapata rail, Cyanolimnas cerverai, is a nearly flightless marsh bird restricted entirely to wetland habitat within the Zapata Swamp region of Cuba. Its extraordinarily limited range, near-flightlessness, and status as one of the most poorly studied rails in the world make it one of the rarest and least understood birds found anywhere in the Caribbean.
A species balanced on a single swamp
With nowhere else on Earth to retreat to, the Zapata rail’s entire future rests on the health of one swamp, making threats like fire, drainage, and invasive predators within that single habitat a matter of survival for the whole species.
Status
Critically Endangered, with an extremely small and declining population restricted entirely to Cuba’s Zapata Swamp.
Zapata Rail: common questions
Where is the Zapata rail found?
This species is restricted entirely to the Zapata Swamp on the island of Cuba, found nowhere else on Earth, making it one of the most geographically limited rail species in the world.
Why is the Zapata rail so rarely seen?
This species is nearly flightless and so rarely encountered that decades have sometimes passed between confirmed sightings by researchers, a combination of secretive habits, dense swamp cover, and an extremely small population.
What threatens the Zapata rail?
This species is threatened by fire, wetland drainage, and invasive predators within the Zapata Swamp, pressures that have pushed its already tiny population toward further decline and left it classified as Critically Endangered.
How much is known about the Zapata rail's biology?
Relatively little, since this species is one of the most poorly studied rails in the world, with basic aspects of its breeding biology and population size still not fully understood by researchers.
