The taxonomic treatment of the Little Shearwater (Puffinus assimilis)/Audubon’s Shearwater (P. lherminieri) complex is being revised, and P. bryani is being recognised as a species: request for information
BirdLife’s taxonomic treatment of the Little Shearwater Puffinus assimilis/Audubon’s Shearwater P. lherminieri complex is being revised to reflect improved understanding of their taxonomy, and P. bryani (Pyle et al. 2011) is to be recognised as a species. Continue reading
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
Gundlach’s Hawk (Accipiter gundlachi), endemic to Cuba, is proposed for downlisting from Endangered to Vulnerable if its population is now stable or increasing as suspected. Continue reading
Archived 2015 topics: White-breasted Thrasher (Ramphocinclus brachyurus): uplist to Critically Endangered?
This discussion was first published as part of the 2013 Red List update, but remains open for comment to enable reassessment in 2015. BirdLife species factsheet for White-breasted Thrasher White-breasted Thrasher Ramphocinclus brachyurus occurs as two subspecies: the nominate race is restricted … Continue reading
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.

In recent years, evidence of declines in the population of T. flavipes has raised concerns over the species’s status. Up-to-date information is requested on this species’s population trend and the severity of potential threats. Continue reading

Bahama Warbler Dendroica flavescens has been split from Yellow-throated Warbler D. dominica following an assessment of its taxonomic status, including analyses of the morphology, vocalisations and genetics of D.(dominica) flavescens and continental D. dominica (McKay et al. 2010) and a subsequent decision by the American Ornithologists’ Union (AOU 2011). Based on current information the species would probably qualify as Near Threatened on the basis that it appears to nearly meet the thresholds for Vulnerable under criteria B1a+b(iii), and probably also criterion C2a(i). However, further information is requested. Continue reading
BirdLife International is currently working on a project to produce a synthesis of all bird taxa, at the species and subspecies level, that are known or thought to have gone extinct since 1500. This is the first time that subspecies extinctions have been systematically documented and analysed, and we hope that the results will provide new insights to support global efforts (including through the BirdLife Partnership) to conserve the world’s threatened birds. Subspecies extinctions are generally not well documented, and so we would greatly appreciate any information and updates (including on recent surveys or rediscoveries) to support this effort.

Archived 2011-2012 topics: Large-billed Seed-finch (Oryzoborus crassirostris): request for information
Large-billed Seed-finch Oryzoborus crassirostris is listed as Least Concern on the basis that it does not approach the thresholds for Vulnerable under any of the IUCN criteria. Recently, it was suggested that this species is still subjected to high trapping pressure for the internal cagebird trade in the Guianas at least (R. Clay in litt. 2010), whilst in Brazil it is described as very uncommon (A. C. De Luca in litt. 2010). Up-to-date information is requested on this species, in particular the estimated rate of decline over 11 years (estimate of three generations) and the severity of trapping pressure and other potential threats.
Orinoco Goose Neochen jubata is listed as Near Threatened under criteria A2c,d; A3c,d; A4c,d on the basis that it is suspected to be undergoing a continued decline of 1-19% over 10 years owing to heavy and ongoing hunting pressure. Recently, concern has been expressed over the conversion of suitable habitat in Venezuela for agriculture, particularly for rice cultivation, some of which is taking place in formerly protected areas (C. Sharpe in litt. 2010).
Semipalmated Sandpiper Calidris pusilla is listed as Least Concern on the basis that it does not approach the thresholds for Vulnerable under any of the IUCN criteria. Recent population trends appear to have been negative for this species in many areas. Up-to-date information is requested on this species, in particular the likely population trend and the severity of threats. Continue reading

Archived 2010-2011 topics: Bahama Oriole (Icterus northropi): newly-split and Critically Endangered or Endangered?
Icterus dominicensis has been been split into four species including Bahama Oriole I. northropi, which appears to have a declining population numbering fewer than 250 mature individuals. It would therefore qualify as Endangered or Critically Endangered depending on the subpopulation structure. Continue reading
Puerto Rican Nightjar Caprimulgus noctitherus is currently listed as Critically Endangered under criterion B1a+b(i,ii,iii), on the basis that its Extent of Occurrence (EOO) was estimated at less than 100 km2, in which its habitat is severely fragmented, with continuing declines suspected in the species’s EOO, Area of Occupancy (AOO) and area, extent and quality of habitat. Recently, however, survey work has extended the species’s known range from Ponce through south-central Puerto Rico to Guayama province in the south-east (Vilella and González 2009).
