One of the world’s rarest birds has been sighted for the first time in almost four decades.
An ornithological search-team has caught a glimpse of the Critically Endangered Zapata Rail Cyanolimnas cerverai, one of the world’s most threatened waterbirds.
The bird was sighted at the Zapata Swamp in south-west Cuba, the location which gives the bird its name.
Fewer than 400 individual Zapata Rails are estimated to exist.
Island rails, often poor fliers, are vulnerable to predators and habitat destruction, and 15 species have become extinct since the 17th Century.
