The global population of this bird is estimated at only a maximum of 3200 breeding pairs and it is estimated that only 2,500 to 10,000 individuals remain. This bird meets population size and decline criteria that necessitate inclusion on the IUCN Red List. The current evaluation status of the Dark-rumped Petrel is Critically Endangered.
