The taxonomic treatment of the Little Shearwater (Puffinus assimilis)/Audubon’s Shearwater (P. lherminieri) complex is being revised, and P. bryani is being recognised as a species: request for information
BirdLife’s taxonomic treatment of the Little Shearwater Puffinus assimilis/Audubon’s Shearwater P. lherminieri complex is being revised to reflect improved understanding of their taxonomy, and P. bryani (Pyle et al. 2011) is to be recognised as a species. Continue reading
In Japan, where it is thought that the majority of the species’s world population breeds, there are 11 islands that are inhabited by more than 10,000 breeding pairs of this species, with birds on at least three of these islands having been shown to be negatively impacted by introduced predators (M. Sato in litt. 2011). In addition to the threat from introduced predators, the species is also susceptible to fisheries bycatch (J. Croxall in litt. 2011). The prevalence of these threats suggests that the species is in population decline; however, further data and observations are required from throughout the species’s range to better assess the current trend.

It has been argued that there are in fact no credible threats to the largest colony on Macquarie Island (S. Garnett in litt. 2011). Casual observations suggest that the population is increasing. Based on the clarification of the species’s status, it is suggested that it could qualify for downlisting to Least Concern on the basis that it no longer meets or approaches the thresholds for Vulnerable under any of the IUCN criteria.
