- 7 stunning bird courtship displays that'll make you swoon August 16, 2017The Eyes Have It Indian Peafowl Pavo cristatus In most bird species, the males are the flamboyant sex, and the females are the ones who do the choosing. This arrangement has come about because the process of producing eggs involves a great amount of energy on the female’s part, so she is extra […]
- The Living Infinite August 16, 2017In the editorial of the special 'marine' edition of our Europe & Central Asia newsletter, Christopher Sands casts his eyes to the ocean. “The sea is everything.It covers seven tenths of the terrestrial globe.

- What's the catch? The fate of Europe's seabirds August 14, 2017Bruna Campos explains why a ‘sea change’ in policy is needed to protect thousands of Europe’s seabirds from the threat of incidental bycatch in fishing gears. “Uneasy lies the head that wears a crown”, Shakespeare famously wrote – and though the great playwright was reflecting upon the power of princes, at BirdLife these words turn […]

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

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.
Archived 2011-2012 topics: Taxonomic changes in the genus Melanitta, part II: suggestions to list M. fusca as Endangered and M. deglandi as Least Concern, and request for information on M. stejnegeri
White-winged Scoter Melanitta fusca has been split into M. fusca, M. deglandi and M. stejnegeri following a review of recent literature (Livezey 1995, Garner et al. 2004, Sangster et al. 2005, Collinson et al. 2006, AOU 2010) and museum specimens by the BirdLife Taxonomic Working Group. Further information is requested and comments are invited on whether the population of M. fusca is likely to have declined at a rate equivalent to 50-79% over the past three generations, and thus whether it qualifies for listing as Endangered under criterion A.

Further information is requested on population trends in these two newly-split species and comments are invited on whether the population of M. nigra is likely to have declined at a rate equivalent to at least 30% over the past three generations, and thus if it qualifies for listing as at least Vulnerable under criterion A.

Archived 2011-2012 topics: White-headed Steamerduck (Tachyeres leucocephalus): uplist to Vulnerable?
A recently published study estimated the total population at 3,428-3,673 adults (Agüero et al. 2011), suggesting that the current population estimate used by BirdLife is correct, but could be refined. However, Agüero et al. (2011) also provide evidence to suggest that the population is in decline. It is suggested that the species could qualify for uplisting to Vulnerable under criterion C2a(ii).

Although BirdLife International does not yet have the capacity to assess global extinction risk at the subspecies level, we are 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.

Archived 2011-2012 topics: Hooded Grebe (Podiceps gallardoi): does it qualify as Critically Endangered?
The results of surveys conducted on more than 50 lakes and lagoons that could hold breeding populations, including the six key waterbodies that held c.40% of the total population in the 1980s, suggest that the rate of decline may have been more rapid than previously thought (Imberti and Casañas 2010). When mean counts from the 1980s are summed across these six main sites, a total of 1,832 adults are estimated to have been recorded; however, surveys at these same sites in 2009 yielded records of only 117 adults. Furthermore, an estimated total of c.580 nests were recorded at these six sites during the 1980s, with not one found during the surveys in 2009 (Imberti and Casañas 2010). The difference in the number of adults recorded suggests that a decline of c.94% has occurred at these sites over c.24 years. This equates to a decline of 90.5% over the past 21 years, assuming an exponential trend. Continue reading
It has recently been noted that the species is becoming more difficult to find during birding tours, and that it could be in rapid decline owing to the on-going destruction of wetlands (P. Morris in litt. 2010). Further details are requested on the severity of threats and likely population trend. Continue reading
Baer’s Pochard Aythya baeri is currently classified as Endangered. Unconfirmed reports from eastern China suggest as many as 3,000 individuals may be hunted every year. If there was sufficient reason to believe the global population of Baer’s Pochard may have declined at a rate of at least 80% over three generations (23 years), then the species should be reassessed as Critically Endangered. Up to date counts from either breeding, passage or wintering sites would be extremely useful in enabling us to estimate population trends in this species. Continue reading
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.

Noble Snipe Gallinago nobilis is currently listed as Least Concern because it was not believed to approach the thresholds for Vulnerable under any of the IUCN criteria. However, if the rates of habitat loss and intensity of hunting pressure described by Cisneros-Heredia (2006) for Ecuador are representative of threats throughout its range, this species could be experiencing an ongoing and moderately rapid decline, likely to be approaching 30% over 14 years (estimate of three generations).
Campbell Islands Teal Anas nesiotis was formally recognised by BirdLife International in 2000 and immediately listed as Critically Endangered under criterion D1, as it had a population of fewer than 50 mature individuals. Since 1999, a breeding, translocation and reintroduction programme has been successful in increasing the total population. Continue reading
Baikal Teal Anas formosa is listed as Vulnerable under criterion A3c on the basis that the population is projected to decline at a rate of 30-49% over 10 years, however counts of wintering individuals in South Korea have increased spectacularly over recent years, and if this species is indeed increasing, it might be eligible for downlisting.
