Red-cockaded Woodpecker Picoides borealis is presently listed as Vulnerable because its population was estimated to number fewer than 10,000 mature individuals and was previously estimated to be declining at a rate of 20-29% over 16 years. It has recently been confirmed, however, that the species’s population has exceeded 10,000 mature individuals since at least 2000, and is provisionally estimated to have numbered 14,500 mature individuals in 2008. In addition, it is now thought that the population is stable and possibly increasing, and has been at least since 2003. Consequently, it is proposed to downlist the species to Near Threatened.

Archived 2012-2013 topics: Laysan Duck (Anas laysanensis): downlist to Vulnerable?

In 2004, Laysan Duck Anas laysanensis was uplisted to Critically Endangered because new information suggested that its population was undergoing extreme fluctuations within its extremely small range on just one island, however following successful translocations, by the 2011 Red List update the population will be estimated to have been increasing for at least five years without the occurrence of extreme fluctuations. It is therefore proposed to downlist the species to Vulnerable under criterion D2. Continue reading

Archived 2012-2013 topics: Red-breasted Parakeet (Psittacula alexandri): request for information

The Red-breasted Parakeet is regarded as the commonest psittacine species in parts of its range; however, substantial declines were noted in Thailand and Laos prior to the turn of the century and local extinctions have occurred (e.g. on Java and Bali) owing to capture for the live bird trade (Juniper and Parr 1998). More recently the species has been described as on the verge of extirpation in Hainan province, China, having been rediscovered there (J. Fellowes in litt. 2010). Further information on this species’s status is requested from throughout its range, including data and observations on the severity of threats and population trends. Continue reading

Archived 2012-2013 topics: Tsingy Wood Rail (Canirallus beankaensis): newly recognised and Near Threatened?

Tsingy Wood Rail Canirallus beankaensis was recently described as a new species by Goodman et al. (2011), who studied the morphology, plumage and genetics of two specimens, in relation to that of Madagascar Wood Rail C. kioloides. It is proposed that the species be listed as Near Threatened under criteria B1a+b(iii,v); C2a(ii), on the basis that it has a very small range and probably has a small population, with continuing declines observed in the area, extent and/or quality of habitat and inferred to be taking place in the number of mature individuals, but with no information on the sub-population structure or evidence to suggest that the population is severely fragmented or restricted to a few locations.

These species’ listing as Near Threatened, based on their suspected rate of decline, may not be tenable given their ability to persist in human-altered habitats. Both S. nigricollis and M. ptilosus have been listed as Near Threatened as a precautionary measure, but their habitat requirements suggest that they should both be downlisted to Least Concern on the basis that they are no longer considered to approach the thresholds for Vulnerable under any of the IUCN criteria.

Archived 2011-2012 topics: Saker Falcon (Falco cherrug): uplist to Endangered?

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

Archived 2011-2012 topics: Rock Partridge (Alectoris graeca): uplist to Near Threatened?

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.

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: Island Scrub-jay (Aphelocoma insularis): does it qualify as Vulnerable?

The species’s population was estimated to number c.9,000 mature individuals (Rich et al. 2004), although the analysis of survey results from 2008 and 2009 suggests there may actually be fewer than 3,000 individuals, and perhaps only c.2,400, but with no clear evidence of a decline (Morrison et al. 2011, The Nature Conservancy 2011). It may be susceptible to catastrophic fires and the introduction of diseases, and there is particular concern over the potential danger from West Nile virus, which arrived in mainland southern California in 2003, but has not yet become established on Santa Cruz Island (c.30 km from the mainland) (Boyce et al. 2011, Morrison et al. 2011).

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.
