Rare glimpse of elusive rail
An ornithological search-team have caught a glimpse of one of the world’s most threatened waterbirds, the Critically Endangered Zapata Rail Cyanolimnas cerverai. The sighting is the first documented in more than four decades and offers hope to conservationists working to ensure its survival.
First described in the early twentieth century, the only nest ever found was reported by ornithologist James Bond -a name appropriated by Ian Fleming (himself a birder) for 007- although even this report is considered doubtful. Little has since been discovered about its behaviour and breeding ecology. Hopes were fading that viable populations of the Cuban waterbird remained.
The fleeting encounter, now made public, occurred in November 2014. After a series of coordinated surveys of south-west Cuba’s Zapata Swamp, ornithologists (including Andy Mitchell and staff from the Cuban Museum of Natural History) struck gold only after deciding to cut thin strips (rides) into the sawgrass to momentarily expose the secretive birds as they moved through the wetland.
“In the first instance, the head protruded from the sawgrass at the side of the ride,” recounted Andy Mitchell. “After a few seconds the bird emerged slowly into the open, stopped for a few seconds before moving off into the sawgrass on the other side of the ride.”
Now rediscovered, conservation efforts for Zapata Rail will target the wetland in which it was spotted, an Important Bird and Biodiversity Area covering 530,695 ha of wetland in southern Matanzas province. A new project management plan will be developed to assess the species’ current population size, distribution and status.
The sighting is the latest victory in BirdLife’s Preventing Extinctions Programme, which aims to halt extinctions through rigorous science and practical conservation delivered by a range of partners on the ground.
