From IUCN Red List:
The Newell's Shearwater is listed as Endangered on the IUCN Red List and was last assessed in 2015 by BirdLife International. This species appears to have declined very rapidly on its main breeding island, possibly associated with the impacts of Hurricane Iniki in 1992, and continues to decline, with two colonies known of in the early 1980s, and possibly a third, now abandoned. Combined with longer term declines owing to a number of other threats, it qualifies as Endangered.
