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