Carrizal Seedeater (Amaurospiza carrizalensis): new information requested.

Carrizal Seedeater Amaurospiza carrizalensis was only described in 2003, shortly after which habitat at the type locality was destroyed. Consequently the species was listed as Critically Endangered with a suspected global population of fewer than 50 individuals and declining. However, surveys in late 2007 and 2008 recorded the species in seven areas in the Caroní basin. Declines are still suspected because other potentially suitable habitat continues to be destroyed. However, the low number of records may be partly due to the difficulty in surveying its habitat. If the species has proven to be more common and widespread and its habitat less threatened than was initially feared then it may warrant downlisting to a lower category of threat. 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. 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 2010-2011 topics: Cipó Canastero (Asthenes luizae): downlist to Near Threatened?

Cipó Canastero Asthenes luizae is currently classified as Vulnerable. However, it has since been shown to occupy a larger range and is now known from at least 15 localities. While its range remains below the threshold for listing the species as Vulnerable under B1, the fact that it is now known from 15 or more locations and that habitat is relatively stable suggests it warrants downlisting to Near Threatened. Comments on this proposed reassessment are welcomed. Continue reading

Archived 2010-2011 topics: Unicoloured Thrush (Turdus haplochrous): new information requested

Unicoloured Thrush Turdus haplochrous is known from only a few localities in north Bolivia. It is currently listed as Near Threatened because the global population is assumed to be small owing to the small number of records. Given the lack of recent records its global population may be extremely small and the species may warrant listing in a higher threat category, but alternatively it may simply have been overlooked and given that it has a potentially large range then it could be Least Concern. Comments on the species’s status are most welcome. Continue reading

Archived 2010-2011 topics: Foothill Elaenia (Myiopagis olallai): is there sufficient information to reassess this species?

Foothill Elaenia Myiopagis olallai is currently listed as Near-Threatened. The species, however, has a very restricted range and is apparently known from just four locations. It would therefore qualify as Endangered under the same criterion if there is evidence that the species is in decline. Comments on the range of this species, likely population trends and the number of locations from where it has been recorded are needed in order to update this assessment. Continue reading

Archived 2010-2011 topics: Steppe Eagle (Aquila nipalensis): information requested.

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

Archived 2010-2011 topics: Rufous Fishing-owl (Scotopelia ussheri): downlist to Vulnerable?

Rufous Fishing-owl Scotopelia ussheri, an Upper Guinea endemic, is currently listed as Endangered because its population is presumed to be very small (i.e. <2,500 mature individuals) and fragmented into smaller subpopulations, which are seriously threatened by forest loss. Recent information suggests that this owl is more widespread than previously thought, and if the population may now be assumed to be larger than 2,500 mature individuals the species may warrant downlisting to Vulnerable.

Archived 2010-2011 topics: Greater Spotted Eagle (Aquila clanga): information requested.

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

Archived 2010-2011 topics: Are São Tomé’s pigeons more threatened by hunting than current Red List status suggests?

Maroon Pigeon Columba thomensis , São Tomé Bronze-naped Pigeon Columba malherbii and São Tomé Green-pigeon Treron sanctithomae are all endemic to the islands of São Tomé, Príncipe and Annobón. Maroon Pigeon, currently listed as Vulnerable under criterion D1, occurs only on São Tomé as does the Least Concern São Tomé Green-pigeon, while the Least Concern São Tomé Bronze-naped Pigeon occurs on São Tomé, Príncipe and Annobón. All three species may be eligible for uplisting owing to the effects of hunting pressure. Comments on these potential category revisions are welcomed, particularly estimates of population size and rate of decline for these species. Continue reading

Archived 2010-2011 topics: Flightless Cormorant (Phalacrocorax harrisi): downlist to Vulnerable?

Flightless Cormorant Phalacrocorax harrisi is endemic to Fernandina and Isabela in the Galápagos Islands, Ecuador, and is currently classified as Endangered because it has a very small breeding range and a population which has been estimated to have undergone extreme fluctuations in the number of mature individuals. It is proposed to reclassify the Flightless Cormorant as Vulnerable under criterion D2 (as the species is capable of becoming Critically Endangered or even Extinct in a very short time period), because the population has not undergone extreme fluctuations and recent data suggests it may be stabilising at a new high .
