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 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.

Greater Scaup Aythya marila breeds in tundra and moorland in northernmost Europe, Asia and North America, and winters in shallow coastal waters and occasionally inland water bodies south of its breeding grounds. The species is currently listed as Least Concern on the basis that it was not thought to approach the thresholds for Vulnerable under any of the IUCN criteria. An analysis of Christmas Bird Count data collected since the mid-1960s suggests that an annual population change of -3.4% has occurred across c.85% of the species’s range in North America, indicating a 75% decline between 1965-1966 and 2005-2006 (Butcher and Niven 2007), and suggesting a decline of c.57% over the last three generations.

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: Bronze-winged Parrot (Pionus chalcopterus): request for information

This species is noted to be declining in Colombia and western Ecuador, owing to the clearance of subtropical forest, which has been severe and rapid on Andean slopes (Juniper and Parr 1998). Anecdotal evidence, based on the frequency of sightings, suggests that the species has declined in Piñas, southern Ecuador, over the past c.15-20 years (M. Sanchez per D. Díaz in litt. 2011). It is also said to have been extirpated from formerly occupied areas such as the Andean slopes of Cauca and Magdalena Valleys in Colombia, again owing to habitat loss (Juniper and Parr 1998).

Archived 2011-2012 topics: Hooded Grebe (Podiceps gallardoi): does it qualify as Critically Endangered?

The results of surveys conducted on more than 50 lakes and lagoons that could hold breeding populations, including the six key waterbodies that held c.40% of the total population in the 1980s, suggest that the rate of decline may have been more rapid than previously thought (Imberti and Casañas 2010). When mean counts from the 1980s are summed across these six main sites, a total of 1,832 adults are estimated to have been recorded; however, surveys at these same sites in 2009 yielded records of only 117 adults. Furthermore, an estimated total of c.580 nests were recorded at these six sites during the 1980s, with not one found during the surveys in 2009 (Imberti and Casañas 2010). The difference in the number of adults recorded suggests that a decline of c.94% has occurred at these sites over c.24 years. This equates to a decline of 90.5% over the past 21 years, assuming an exponential trend. Continue reading

Archived 2011-2012 topics: Purple-naped Lory (Lorius domicella): uplist to Endangered?

Purple-naped Lory Lorius domicella is currently listed as Vulnerable because it is assumed to have a small population of fewer than 10,000 mature individuals that is declining.
On limited available evidence it seems plausible that the population has declined to fewer than 2,500 mature individuals and given the threats a continuing decline is likely. This would qualify the species as Endangered if all sub-populations support fewer than 250 mature individuals. Comments on the likely population size and structure, and its status on Ambon and elsewhere in South Maluku are invited to accurately assess this species’s status. Continue reading

Baer’s Pochard Aythya baeri is currently classified as Endangered. Unconfirmed reports from eastern China suggest as many as 3,000 individuals may be hunted every year. If there was sufficient reason to believe the global population of Baer’s Pochard may have declined at a rate of at least 80% over three generations (23 years), then the species should be reassessed as Critically Endangered. Up to date counts from either breeding, passage or wintering sites would be extremely useful in enabling us to estimate population trends in this species. Continue reading

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
