West Indian Whistling-duck (Dendrocygna arborea): request for information

Surveys carried out in Cuba – the most significant part of the species’s range both in size and population numbers – have shown the species to be more widespread on the main island and adjacent offshore islands than was previously thought. Present knowledge suggests that the species does not meet the thresholds for Vulnerable under any of the IUCN Red List criteria and may warrant downlisting. Continue reading

Streaked Shearwater (Calonectris leucomelas): eligible for uplisting?

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.

Royal Penguin (Eudyptes schlegeli): eligible for downlisting?

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. Based on the clarification of the species’s status, it is suggested that it could qualify for downlisting to Least Concern on the basis that it no longer meets or approaches the thresholds for Vulnerable under any of the IUCN criteria.

Archived 2014 discussion: Himalayan Vulture (Gyps himalayensis): request for information

It has been suggested that the species, like many vulture species in South Asia, is potentially being impacted by diclofenac, in particular when young birds descend to lowland areas in South and South-East Asia, where there is a high prevalence in the veterinary use of the drug by farmers (S. Mahood in litt. 2008, 2011; C. Bowden in litt. 2011).

Concern has recently been expressed over this species’s status, as there is evidence that it is declining in abundance (per Hofmeyr 2012). Following recent research, it has been recommended that the species be classified as Vulnerable because of past and probable future decreases in its population and because of its susceptibility to on-going land conversion, climate change and possibly increased predation (Hofmeyr 2012).

A recent study by Vetter (2009) used remote sensing techniques to track the rate and spatial pattern of forest loss in the North Maluku Endemic Bird Area between 1990 and 2003, and project rates of deforestation over the next three generations for restricted range bird species found in this region, with consequent recommendations for category changes on the IUCN Red List. Vetter (2009) states that this species could be a candidate for uplisting to Endangered, based on this forest loss analysis and knowledge that capture over quota limits was still taking place.

Blue-bellied Parrot Triclaria malachitacea is currently listed as Near Threatened under criteria A2c,d; A3c,d; A4c,d on the basis that an ongoing population decline of 20-29% over 10 years is suspected to be taking place owing to habitat loss and trapping. Anecdotal evidence from Rio Grande do Sul suggests that, despite Bencke’s (1996) estimation of c.10,000 birds in the state, the species may now be scarce there (J. Gilardi in litt. 2010).

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

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: Greater Scaup (Aythya marila): uplist to Near Threatened or 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.
