BirdLife International announces more Critically Endangered birds than ever before

14-05-2009

BirdLife International's latest evaluation of the world's birds has revealed that more species than ever are threatened with extinction. A staggering 1,227 species (12%) are now classified as Globally Threatened but the good news is that when conservation action is put in place, species can be saved.

"In global terms, things continue to get worse – but there are some real conservation success stories this year to give us hope and point the way forward", said Dr Leon Bennun, BirdLife's Director of Science and Policy.

The rarest of the rare are growing in number

BirdLife International's annual Red List update, on behalf of the IUCN, now lists 192 species of bird as Critically Endangered, the highest threat category, a total of two more than in the 2008 update.

A recently discovered species from Colombia - Gorgeted Puffleg Eriocnemis isabellae - appears for the first time on the BirdLife/IUCN Red List, being listed as Critically Endangered. The puffleg, a flamboyantly coloured hummingbird, only has 1,200 hectares of habitat remaining in the cloud forests of the Pinche mountain range in south-west Colombia and 8% of this is being damaged every year to grow coca.

Sidamo Lark Heteromirafra sidamoensis from the Liben Plain of Ethiopia has also been uplisted to this category due to changes in land use, and is in danger of becoming mainland Africa’s first bird extinction. And coinciding with the 200th anniversary of Charles Darwin's birth, one of the Galapagos finches, Medium Tree-finch Camarhynchus pauper also becomes Critically Endangered, partly as a result of an introduced parasitic fly.

Common bird declines

But it's not only rare birds that are becoming rarer, common birds are becoming less common. In eastern North America, Chimney Swift Chaetura pelagica is fast disappearing from the skies. Following continent-wide declines of nearly 30% in the last decade alone, this common species has been uplisted to Near Threatened.

"Across Africa, widespread birds of prey are also disappearing at an alarming rate, and emblematic species such as Bateleur (Terathopius ecaudatus) and Martial Eagle (Polemaetus bellicosus) have been uplisted as a result. These declines are mirrored in many species, in every continent", said Jez Bird, BirdLife's Global Species Programme Officer.

Where there's a will there’s a way

But it's not all doom and gloom, conservation does work and there are some great examples in this year's BirdLife/IUCN Red List. In Brazil, Lear's Macaw Anodorhynchus leari has been downlisted from Critically Endangered. Named after the English poet, this spectacular blue parrot has increased four-fold in numbers as a result of a joint effort of many national and international non-governmental organisations, the Brazilian government and local landowners.

In New Zealand, Chatham Petrel Pterodroma axillaris has benefited from work by the New Zealand Department of Conservation and has consequently been downlisted from Critically Endangered. And in Mauritius the stunning, Mauritius Fody Foudia rubra has been rescued from the brink after the translocation and establishment of a new population on to a predator-free offshore island. It has now been downlisted to Endangered.

Similar work is now also underway for 32 Critically Endangered species as part of the BirdLife Preventing Extinctions Programme.

“Both the petrel and fody have suffered from introduced invasive species, and tackling these is one of the 10 key actions needed to prevent further bird extinctions that BirdLife has indentified. What this year's Red List changes tell us is that we can still turn things around for these species. There just has to be the will to act and the resources to back this up”, said Dr Stuart Butchart, BirdLife's Global Research and Indicators Coordinator.

“It extremely worrying that the number of Critically Endangered birds on the IUCN Red List continues to increase, despite the number of successful conservation initiatives around the world”, said Simon Stuart, Head of IUCN’s Species Survival Commission. “The IUCN Red List is the global standard when it comes to measuring species loss so we urge governments to take the information contained in it seriously and do their level best to protect the world’s birds.”

Notes for Editors

BirdLife International is a global alliance of conservation organisations working in more than 100 countries and territories that, together, are the leading authority on the status of birds, their habitats and the issues and problems affecting theme.

BirdLife is the Red List Authority for birds for the IUCN Red List. Categories include: Critically Endangered (facing an extremely high risk of extinction in the wild), Endangered (facing a very high risk of extinction in the wild), Vulnerable (facing a high risk of extinction in the wild), Near Threatened (close to qualifying for Vulnerable) and Least Concern (species not qualifying for the other categories, including widespread and abundant species). Species are assigned to categories using criteria with quantitative thresholds for population size, population trend, range size and other parameters. For more information visit: [url]http://www.iucnredlist.org[/url]

77 species have changed their IUCN Red List categories. Many of these are a result of an improved knowledge of populations or threats but of the 12 species that changed category owing to changes in their population size, rate of decline or range size, eight were uplisted to a higher level of threat.

In total, nine species have been uplisted (or newly listed as) to Critically Endangered (Flores Hawk-eagle Spizaetus floris, Nightingale Reed-warbler Acrocephalus luscinius, Marquesan Kingfisher Todiramphus godeffroyi, Crow Honeyeater Gymnomyza aubryana, Medium Tree-finch Camarhynchus pauper, Palila Loxoides bailleui, Sidamo Lark Heteromirafra sidamoensis, plus Gorgeted Puffleg Eriocnemis isabellae, Antioquia Brush-finch Atlapetes blancae which are newly described and Critically Endangered) and six have been downlisted from Critically Endangered to Endangered (Chestnut-bellied Hummingbird Amazilia castaneiventris, Minas Gerais Tyrannulet Phylloscartes roquetti, Kaempfer's Tody-tyrant Hemitriccus kaempferi, Mauritius Fody Foudia rubra, Chatham Petrel Pterodroma axillaris, Lear's Macaw Anodorhynchus leari) and one has been reclassified from Critically Endangered to Not Recognised (Bulo Burti Boubou Laniarius liberatus).

Other regional highlights

Americas

Hooded Grebe Podiceps gallardoi has been uplisted from Near Threatened to Endangered. This species was only described in 1974 and is found at only a few lakes in south-west Argentina and Chile. It has undergone a rapid population decline and work is underway to ascertain the causes of this decrease. For more information click here

Palila Loxioides bailleui has been uplisted to Critically Endangered. This large finch is found in Hawaii and becomes the 13th Critically Endangered species for those islands, making them the world’s biggest extinction hotspot for birds. For more information click here

2009年红色名录亚洲鸟类的级别调整

基本上变动不大，可参考

[url]http://www.birdlifeforums.org/WebX?233@@.2cba6754!enclosure=.2cba6755[/url]

跟中国鸟类关系较大的，就是绿孔雀调升为濒危，斑背大尾莺下降为近危。

补充

今天替同事整理在日本的新闻发报稿，我说今年其实对东北亚而言变动并不大，曾经讨论过的丹顶鹤、中华秋沙鸭等都维持不变，最大的新闻价值是斑背大尾莺级别下调，但这并不表示它的情况有好转，只是表明在中国观察鸟类的人多了，对本种的认识更充分，了解到从全球角度而言，它不能视为受胁。中国的观鸟者行列壮大，对了解很多鸟类的状况是有很大的贡献的。

今年来不及把栗斑腹鹀评审，但相信在一两年内它的级别会提升。

在云南工作，有些意外地得知版纳地区吃野生动物是非常普遍的现象。我有朋友在一个从事扶贫的NGO工作，说去版纳的那些地方，地方上总是要请吃野生动物，刺猬、穿山甲等。也有吃绿孔雀的，据说味道很腥。要做这样的行为改变，还是有很多事情要做。

一步一步慢慢来吧~

对三餐不得温饱的人来说，很难劝谕他们别吃野生动植物。。。

不过那些高高在上的人也要吃就说不过去了。。。
