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.

Further information on the species is requested from all parts of its range, with particular emphasis on population estimates and trends, as well as likely threats. Continue reading

Long-tailed Woodnymph (Thalurania watertonii): request for information

Long-tailed Woodnymph Thalurania watertonii is listed as Near Threatened under criterion B1a+b(i,ii,iii,iv,v) on the basis that it was thought to have a moderately small range within which its habitat is severely fragmented and its population is suspected to be declining owing to habitat loss. The species’s Extent of Occurrence has now been updated and is estimated at 34,800 km2, which no longer approaches the threshold for Vulnerable under the B1 criterion. This suggests that the species is eligible for downlisting to Least Concern.

Further information is requested on the likely trend over a period of three generations. Continue reading

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.

Plain-flanked Rail (Rallus wetmorei): request for information

The total population might be assumed to fall in the range of 50-249 mature individuals, based on the paucity of recent records and the small number of known localities. Its population is suspected to be rapidly decreasing as its mangrove habitat is lost or degraded owing to coastal housing, tourist and industrial developments, pollution from domestic sewage and agricultural run-off, sedimentation and the restriction of water flow by road-building. In the absence of further information, and if the known population is indeed fewer than 250 mature individuals, in continuing decline and with over 90% of mature individuals in one sub-population, the species might qualify as Critically Endangered under criterion C2a(ii).

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

Bahia Tapaculo (Eleoscytalopus psychopompus): downlist to Endangered?

Bahia Tapaculo Eleoscytalopus psychopompus is currently listed as Critically Endangered under criterion B1a+b(i,ii,iii,iv,v). Recent records have extended the species’s known range, and editing of its range map has produced a revised EOO estimate of 7,900 km2. This suggests that the species is no longer eligible for Critically Endangered or Endangered status under the B1 criterion. Continue reading

Tooth-billed Pigeon (Didunculus strigirostris): is this species Critically Endangered?

It is unclear whether, since 2006, the species has declined further and new information is urgently required to clarify recent records of Tooth-billed Pigeon. At the same time, if the apparent paucity of recent records reflects a further population decline in recent years, a conservative outlook suggests its global population may have been reduced to fewer than 250 mature individuals, qualifying the species as Critically Endangered under criterion C2a with an on-going decline in progress. Continue reading

Andean Flamingo (Phoenicoparrus andinus), Puna Flamingo (P. jamesi) and Chilean Flamingo (Phoenicopterus chilensis): downlist all to Least Concern?

Andean Flamingo Phoenicoparrus andinus is currently listed as Vulnerable under the A criterion, and James’s Flamingo P. jamesi and Chilean Flamingo Phoenicopterus chilensis are listed as Near Threatened under the A criterion. The results of surveys carried out for the International Simultaneous Census and Simultaneous Census of Network Sites in 2010 and six previous years since 1997 suggest that the population trends of these species are in fact stable or increasing (Marconi et al. in press). Continue reading

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. Continue reading

Venezuelan Wood-quail (Odontophorus columbianus): request for information

Venezuelan Wood-quail Odontophorus columbianus is listed as Near Threatened under criterion B1a+b(i,ii,iii,iv) because, although it has an Extent of Occurrence estimated at 9,400 km2, within which it is suspected to be declining owing to habitat loss and hunting pressure, the population is not considered to be severely fragmented or restricted to a few locations. Up-to-date information is requested on this species’s population, the likely rate of decline over 12 years (estimate of three generations) and the severity of threats.

Palm Crow (Corvus palmarum): request for information

Palm Crow Corvus palmarum is listed as Near Threatened under criterion B1a+b(iii,v) on the basis that it was considered to have a moderately small range in which habitat degradation and hunting are causing a population decline. The species’s Extent of Occurrence (EOO) has recently been updated by BirdLife and the new EOO is estimated at 103,400 km2, which no longer approaches the threshold for Vulnerable under the B1 criterion.

Rio de Janeiro Antbird (Cercomacra brasiliana): request for information

Rio de Janeiro Antbird Cercomacra brasiliana is listed as Near Threatened under criterion B1a+b(i,ii,iii,v) on the basis that it was known from fewer than 10 locations within a moderately small range, in which it was generally considered rare or uncommon, with numbers probably declining. Following on from improved knowledge of its distribution in areas where it had previously been overlooked (del Hoyo et al. 2003), the species’s Extent of Occurrence has been updated by BirdLife.
