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.

To explore the impact of uncertainty on the overall trend and category, a number of alternative scenarios were also explored (see attached spreadsheet). When the trend assessments were re-run, only the most optimistic scenarios altered the potential Red List category (from Endangered to Vulnerable or Near Threatened), i.e. assuming Italy is experiencing the minimum decline rate and countries with unknown trends are stable.
This suggests that the species’s global status ought to be revised to Vulnerable under criterion A4b,c,d,e, as it is projected to suffer a rapid population reduction (30-49% decline over three generations). Comments on this proposal and any relevant information (particularly including trend information for additional countries) are invited. Continue reading
The species’s population trend is suspected to be stable; however, the islands on which it is known to breed are inhabited by introduced cats, rats and dogs. The species is also potentially impacted by logging, which may actually be the most important threat (C. Collins pers. comm.). Any evidence that suggests a decline is occurring in the population might make the species eligible for uplisting to Endangered under criterion C2a(ii). Continue reading
A recently published study has improved our knowledge of this species’s status, including the threats it faces. Sato et al.

Black-footed Albatross Phoebastria nigripes is currently listed as Endangered under criterion A4b,d, on the basis that its population is projected to decline by more than 60% over 56 years (estimate of three generations), as modelled using a moderate scenario for fisheries bycatch of 8,000 birds per year (Lewison and Crowder 2003). The recent analysis presented by Arata et al. (2009) brings into question the validity of the species’s current Red List status. It suggests that the rate of projected decline should be lowered, which could result in the species becoming eligible for downlisting. Continue reading

Flightless Cormorant Phalacrocorax harrisi is endemic to Fernandina and Isabela in the Galápagos Islands, Ecuador, and is currently classified as Endangered because it has a very small breeding range and a population which has been estimated to have undergone extreme fluctuations in the number of mature individuals.
