Some such new data have been provided in recent publications by Moshkin (2010) and Levin (2011), who present past and present population sizes in the most important range states based on new data sources, particularly for local population trends. In comparison to the figures previously used by BirdLife, key differences in Moshkin’s (2010) estimates include higher estimates of 5,218 pairs in Kazakhstan and 6,500 pairs in Russia in 1990 and a lower estimate of 1,500 pairs in China in 2010. In addition, Levin (2011) gives a new present-day estimate of fewer than 1,000 pairs in Kazakhstan. We discuss these in turn below and consider their significance for the overall rate of decline, the calculation for which can be viewed in the spreadsheet attached. Continue reading
Despite on-going uncertainty about the size and trend of some national populations, a balanced assessment of the available evidence suggests that overall the population of this species is probably declining at a rate approaching 30% over 12 years (three generations). For this reason, it is proposed that the species be uplisted to Near Threatened. Comments on this proposal are welcome, as are any quantitative data that could further inform the assessment. Continue reading
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
Available information suggests that the species’s global status ought to be revised to Near Threatened under criterion C2a(ii), on the basis that it has a moderately small population, which may approach the threshold for classification as Vulnerable, but which is not currently thought to be undergoing a continuing decline. Continue reading
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: Taxonomic changes in the genus Melanitta, part II: suggestions to list M. fusca as Endangered and M. deglandi as Least Concern, and request for information on M. stejnegeri
White-winged Scoter Melanitta fusca has been split into M. fusca, M. deglandi and M. stejnegeri following a review of recent literature (Livezey 1995, Garner et al. 2004, Sangster et al. 2005, Collinson et al. 2006, AOU 2010) and museum specimens by the BirdLife Taxonomic Working Group. Further information is requested and comments are invited on whether the population of M. fusca is likely to have declined at a rate equivalent to 50-79% over the past three generations, and thus whether it qualifies for listing as Endangered under criterion A. Continue reading
Archived 2011-2012 topics: Taxonomic changes in the genus Melanitta, part I: suggestion to list M. nigra as Vulnerable and request for information on M. americana
Black Scoter Melanitta nigra has been split into M. nigra and M. americana following a review of recent literature (Livezey 1995, Garner et al. 2004, Sangster et al. 2005, Collinson et al. 2006, AOU 2010) and museum specimens by the BirdLife Taxonomic Working Group. Further information is requested on population trends in these two newly-split species and comments are invited on whether the population of M. nigra is likely to have declined at a rate equivalent to at least 30% over the past three generations, and thus if it qualifies for listing as at least Vulnerable under criterion A. Continue reading
Asian Desert Sparrow Passer zarudnyi has been split from Desert Sparrow P. simplex. Data are lacking on this species’s distribution and population size, and little is known about potential threats. In addition, data are required on the species’s population trend, which is difficult to judge owing to its apparently nomadic movements and the possibility that the species has always been rare. Further information on the species would be welcomed. Continue reading

Madeira Laurel Pigeon Columba trocaz is currently classified as Near Threatened, however implementation of conservation measures has led to a significant recovery of the species’s population and range such that it no longer approaches the Red List thresholds to be considered as threatened. It is therefore proposed to revise its status to Least Concern Continue reading
Blue Chaffinch Fringilla teydea is currently listed as Near Threatened, however an increase in the species’s range on Tenerife strongly suggests that its overall population size has also increased. Notwithstanding the precarious state of the Gran Canaria subspecies, this suggests that the global status of the species ought to be revised to Least Concern. Continue reading
Archived 2010-2011 topics: Fuerteventura Stonechat (Saxicola dacotiae): reclassify as Near Threatened or Least Concern?
Fuerteventura Stonechat Saxicola dacotiae is currently listed as Endangered, however a revised population estimate, improved knowledge of its habitat preferences, and lack of any evidence for overall decline, suggest that the global status of the species ought to be revised to either Near Threatened or Least Concern.

Dark-tailed Laurel Pigeon Columba bollii is currently classified as Near Threatened, however in recent years the extent and quality of the species’s habitat have continued to show positive trends. This suggests that the global status of this species ought to be revised to Least Concern. Continue reading
Archived 2010-2011 topics: Lesser Kestrel (Falco naumanni): downlist to Near Threatened or Least Concern?
Lesser Kestrel Falco naumanni is currently listed as Vulnerable, however since the 1990s the species’s breeding population has been stable or increased in south-western Europe and since c. 2000 its population in Europe, Russia and Central Asia is suspected to have been stable or even slightly increasing. This suggests that its global status ought to be revised to either Near Threatened or Least Concern. Continue reading
Steppe Eagle Aquila nipalensis breeds widely from Eastern Europe through Central Asia to the steppes of Mongolia. It winters in Africa and western Asia and is currently considered Least Concern on the IUCN Red List because of its large range and population. While population trends have not been assessed for the global population, anecdotal sources suggest it is declining. To ascertain global trends data are needed from the Asian breeding grounds and African wintering grounds. Comments on likely population trends are invited. Continue reading
Greater Spotted Eagle Aquila clanga is currently listed as Vulnerable on the IUCN Red List. No comprehensive assessment of the species’s population size globally or population trends in different parts of its range exists; however, given the species’s massive global range it is highly plausible that its population exceeds 10,000 mature individuals (the threshold for listing as VU under criterion C) and may warrant downlisting. Information about the species’s population size and declines are requested to improve our assessment of its global status. Continue reading
