Important Bird Areas identified for Critically Endangered bird species

Sites marked in red support more than one Critically Endangered species: the high density of such sites in South and South-East Asia reflect the distribution of several broad-ranging Critically Endangered vulture species which co-occur at many IBAs in these regions. IBAs are still being identified for Critically Endangered birds in New Zealand, French Polynesia, Northern Mariana Islands and the Federated States of Micronesia.


Most Critically Endangered species are in decline, while some await discovery
