This newly described species is listed as Critically Endangered because there are no known populations and the last record is from 1971; consequently if it does remain extant it is assumed that any population must be tiny. The species was collected on the Llano de Ovejas, a small plateau at 2,400-2,800 m. This species has […]

Rarest birds in the World: Christmas Island Frigatebird
The Christmas Island frigatebird (Fregata andrewsi) has a small declining population which breeds within on just one small island.

The Christmas Island Frigatebird is the rarest of the five species […]
Rarest birds of the World: White-shouldered Ibis
The White-shouldered Ibis population is very rapidly diminishing. The reasons are not fully understood but certainly habitat loss, hunting and disturbance are on-going threats. If effective protection measures could be in place in north-eastern Cambodia and along the Mekong channel, the species largest population may be saved. It is now estimated at a 650 mature […]
Rarest birds of the World: St. Helena Plover, the Wirebird
This species population is very small and declining because of a degrade of suitable nesting ground. The population has shown some signs of recovery and is now above 250 mature individuals. St. Helena, then uninhabited, was discovered in 1502 and the introduction of goats in 1513 heralded the speedy destruction of the forests, which were […]
