Climate Change Hitting Bird Species, Shows Study
GERMANY: May 20, 2008
BONN, Germany - One in eight of the world's birds are at risk of extinction
as climate change puts birds under great pressure, a leading conservation
group warned on Monday.
The population of rare birds such as the Floreana mockingbird of the
Galapagos Islands or the spoon-billed sandpiper, which breeds in
north-eastern Russia and winters in south Asia, has declined sharply and
they could go extinct, the International Union for Conservation of Nature
said in a report.
The 2008 "Red List for Birds" report, published on the first day of a May
19-30 UN conference about biodiversity in the German city of Bonn, said
1,226 species of bird were now threatened.
The annual report, closely watched among conservationists, added eight of
the world's 10,000 bird species to the Critically Endangered category, the
greatest level of threat.
"The latest update of the IUCN Red List shows that birds are under enormous
pressure from climate change," said Jane Smart, head of the IUCN Species
Programme. The IUCN groups governments, conservation groups and scientists.
Long-term drought and sudden extreme weather are putting additional stress
on habitats that threatened species depend on, said the report, noting that
extinction rates were rising on continents, rather than on islands where,
historically, most extinctions have occurred.
Of the 26 species that moved category due to changes in their population
size, rate of decline or range size, 24 were moved up to a higher level of
threat.
CURLEW, WARBLER
They included the Eurasian curlew and Dartford warbler, which lives in
Europe and north-west Africa. Both were previously in the "Least Threatened"
category.
"We urge governments to take the information contained in (the report)
seriously and do their level best to protect the world's birds," said Smart.
The UN Climate Panel says that burning of fossil fuels is stoking global
warming.
The report showed that Brazil and Indonesia had the highest number of
threatened bird species with 141 and 133 respectively.
The group picked out several other species, including the Mallee emuwren in
Australia which has suffered from years of drought and is seeing its
population shrink sharply.
Its habitat has become so fragmented that a single bushfire could be
catastrophic, said the report.
In the Galapagos Islands, the population of the Floreana mockingbird has
fallen to fewer than 60 from an estimated 150 in 1996 and is now on the
Critically Endangered list because the species is vulnerable to extreme
weather.
The report also pointed to some species that had fared better as a result of
conservation efforts, including the Marquesan Imperial-pigeon and the little
spotted kiwi.
Around 4,000 delegates at the UN meeting of the Convention on Biodiversity
will discuss ways to safeguard the range of species and try to slow the rate
of extinctions among plants and animals.
