Archived 2014 discussion: Hyacinth Macaw (Anodorhynchus hyacinthinus): request for information

Hyacinth Macaw Anodorhynchus hyacinthinus is currently listed as Endangered under criterion A2c,d because the population has undergone very rapid declines in the past and the threats of illegal trapping for the cagebird trade and habitat loss persist. The rate of past declines has been estimated to be in the range of 50-79% over 45 years (estimate of three generations). It is now unclear whether the population as a whole is still declining at a rate of 50-79% over 45 years. Continue reading

Archived 2014 discussion: Yellow-billed Magpie (Pica nuttalli): eligible for uplisting?

There is now evidence that this species has suffered high levels of mortality and a severe population decline owing to a high susceptibility to West Nile virus (Airola et al. 2007, Crosbie et al. 2008), since its documented arrival in California in summer 2003 (Reisen et al. 2004), with data suggesting a decline of 42-49% from 2004 to 2006 (Crosbie et al. 2008). Comments are invited on the potential uplisting of this species under criterion A, and further information is requested, particularly on whether the observed rapid decline and high mortality have continued up until the present.

Lesser Masked-owl Tyto sororcula is currently treated as Data Deficient because most records are from the 19th or early 20th century. given the rate of habitat loss within its range it seems prudent to reclassify the species as Vulnerable under criterion A2 owing to suspected rapid population declines in excess of 30% over the past three generations.

Archived 2011-2012 topics: Yelkouan Shearwater (Puffinus yelkouan): uplist to Vulnerable?

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

Archived 2011-2012 topics: Little Bustard (Tetrax tetrax): what are the trends in Russia and Central Asia?

The Little Bustard Tetrax tetrax has a Palaearctic distribution and two geographically separated breeding populations: the western (found in the EU); and eastern (breeding in western and central Asia). It is currently classified as Near Threatened under criterion A on the IUCN Red List, because it is suspected to have undergone a moderately rapid global population decline approaching 30% over three generations. If the global population is suspected to be undergoing an overall decline at a rate of 30-49% in 30 years, the global status of Little Bustard would need to be revised to Vulnerable. To re-evaluate its status, more data are needed about the size and trends of populations in the east, particularly from Russia and Central Asia. Continue reading

Archived 2011-2012 topics: Long-tailed Duck (Clangula hyemalis): uplist to Endangered?

Long-tailed Duck Clangula hyemalis is a widespread circumpolar species that breeds mainly in the Arctic tundra and winters generally to the south, mainly far offshore. It is currently listed as Least Concern because it was not thought to approach the thresholds for Vulnerable under any of the IUCN Red List criteria. Taking the 27-year decline rates calculated for the Baltic and North American populations, and assuming that the two other smaller populations have remained stable, the species’s global population may be declining at a rate of more than 50% over three generations, which would qualify the species for uplisting to Endangered under criterion A.

Archived 2011-2012 topics: Black-footed Albatross (Phoebastria nigripes): eligible for downlisting?

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

Malaysian Whistling-thrush Myophonus robinsoni is currently listed as Least Concern. New information suggests it is suspected to be declining and the range and population size estimates meet the thresholds for Endangered under the B criterion and Vulnerable under the C criterion, however the species does not qualify for these categories because its population is not considered to be severely fragmented and there is insufficient information available to ascertain its sub-population structure. Is therefore proposed that the species be uplisted to Near Threatened. Continue reading
