Climate could kill Wales Red Kites


Wales could lose one of its rarest birds of prey, the Red Kite, because of climate change and other human impacts, WWF Cymru warned today.

Morgan Parry, Head of WWF Cymru, said, "This beautiful creature can be found mainly in rural Ceredigion but they could soon be under threat throughout the whole of Europe. Scientists have projected that the Red Kite will suffer up to 86 per cent loss of its habitat due to climate change and other human impacts unless we act now.

WWF on birds and global warming

The World Wildlife Fund released a major and alarming report today on birds and climate change. You can find the pdf here:

“Robust scientific evidence shows that climate change is now affecting birds’ behaviour,” said Dr Karl Mallon, Scientific Director at Climate Risk Pty Ltd and one of the authors of the report. “We are seeing migratory birds failing to migrate, and climate change pushing increasing numbers of birds out of synchrony with key elements of their ecosystems.”

Swans deliver a climate change warning


For decades, the arrival of the first V-shaped flights of Bewick's swans in Britain's wetlands after a 2,000-mile journey from Siberia heralded the arrival of winter.

This year, a dramatic decline in numbers of the distinctive yellow-billed swans skidding into their winter feeding grounds could be the harbinger of a more dramatic shift in weather patterns: global warming. Ornithologists at the main reserves that host the birds, the smallest of Britain's swans, said only a handful had appeared on lakes and water courses. Normally, there would be several hundred.

Sooty Shearwaters may be threatened by climate change



But their remarkable feat may be coming to an end. Recent studies have shown that some sooty shearwater breeding colonies have declined by more than 40 percent, which researchers believe is a result of warming ocean temperatures. As sea temperatures rise, possibly from global warming, the mixing of colder, nutrient-rich water from the ocean depths with warmer surface water declines, limiting the growth of algae and everything that feeds upon it.--- Read More

Warm winter meant rare bird sightings

In 2005/06, Canada experienced its warmest winter since modern record-keeping began, with average temperatures 3.9 degrees Celsius above normal. And, more Ontario birdwatchers than ever before were treated to sightings of two southern specialists, the Red-bellied Woodpecker and the Northern Cardinal last winter.

Kerrie Wilcox, national coordinator of Project FeederWatch, a North American-wide survey of birds coming to backyard feeders, noted that the percentage of feeders visited by Red-bellied Woodpeckers in Ontario reached an all-time high last winter, occurring at nearly 15 per cent of feeders. The Red-bellied Woodpecker's range has been creeping northward from its core in the mid- Atlantic and southeastern states over the last decade. This species rarely visited more than five per cent of sites just five years ago.

Northern Cardinals were reported at a whopping 72% of feeders in Ontario this past winter. While many people in southern Ontario are now accustomed to seeing cardinals at their feeders, this southern species was almost unheard of in the province 100 years ago.

Range expansions in southern species such as these could be a signal that changes in climate are making northern regions more hospitable. Likewise, it would be expected that birds located at the southern edge of their range would retract with warmer climatic conditions. One feeder species that may be showing this trend is the Gray Jay.

The percentage of feeders visited by Gray Jays has decreased to 7% since a peak of 14.1% of Ontario feeders in 1999. Climate change may be altering the Gray Jay's habitat in the southern end of its range. While other birds fly south to warm places for the winter, the Gray Jay stays put, surviving on tiny bits of food it has stored in an estimated 100,000 locations, usually under scales of bark on spruce trunks and branches. ...Read More...

Cassin's Auklet breeding failure linked to Climate Change


The 2005 breeding failure highlights how anomalies in the climate can hit the bottom of the food web and then reverberate all the way up. While the auklets showed the most dramatic and immediate effects, the scientists say the lack of krill likely impacted everything from salmon to whales.

There are fears global warming will eventually wipe out the seabird colonies.

"What we are concerned about is that events like we saw last year are going to become more frequent because of climate change," Hipfner says. "That's what we're really worried about."...Read More

Changes to bird life in the U.K.

Even more profound are the changes occurring in the nation's wildlife, and in particular, birds. The redwing, a species of thrush that was once a frequent visitor from Scandinavia in winter, is disappearing from our skies. 'It used to fly to Scotland to eat our berries and avoid the freezing conditions of its Scandinavian homeland, but now winters have become so mild over there, it is staying put,' said Paul Stancliffe of the British Trust for Ornithology.

Then there is Cetti's Warbler, a small, brownish bird with a notable, loud song, and a penchant for warm weather. It first arrived in Britain in 1961 and made a home for itself in Hampshire, one of the warmest corners of the British Isles. Then global warming began to take its steamy grip of the United Kingdom. Today temperatures have soared so high across Britain that the Cetti reached the Scottish border last year and now breeds regularly as far north as Yorkshire.

Similarly, the blackcap, a distinctive grey species of warbler found in many parts of Europe, used to make a point of migrating to the Mediterranean and north Africa during winter. Now conditions have become so warm that warblers in Germany have found it just as pleasant to migrate to the UK instead, thus saving it a lengthy continental journey. For the blackcap, Britain is the new Adriatic.

Global warming may submerge Northwestern Hawaiian Islands

For the first time, a team studied the threats of rising sea levels to the Northwestern Hawaiian Island chain. Jason Baker of the Pacific Islands Fisheries Science Center — part of the U.S. National Oceanic and Atmospheric Administration — led the team. Their study suggests that monk seals, sea turtles and millions of sea birds could go extinct before the end of this century due to global warming. Read More...

Once virtually extinct heron returns to breed in London


Their move north to London from nesting sites on the south coast could be a sign of climate change, experts believe...

Many people had been astonished that the bird, more commonly seen in the Mediterranean, was now breeding in this country.

Warmer winters "will certainly have benefited" its spread, he said.

Thames Water's biodiversity manager Andy Tomczynski said: "We are delighted that these rare and beautiful birds have chosen to breed in the capital and we hope they can go on and establish a permanent colony at our Walthamstow reservoirs.

"Little Egrets do not cope well with harsh winters and only started breeding in the UK a decade ago, colonising parts of the south coast. Their nesting further to the north could be another sign of climate change."

The Barn Owl situation in Great Britain


Recent claims of a link between low Barn Owl numbers and climate change:
Climate change has led to a catastrophic crash in the population of Britain's barn owls, it was claimed today.


See also: Extreme weather hits barn owl numbers:
Extreme weather conditions are to blame for a catastrophic fall in the number of barn owls, an expert said today.

As few as 1,000 breeding pairs of the distinctive bird may have survived in Britain, a dramatic fall from an estimated 4,000 pairs last year.



These claims have also been disputed: Barn owl fears exaggerated, says expert
Claims that extreme weather conditions had dramatically reduced the number of breeding pairs in Britain to as few as 1000, from 4000 the year before, were dismissed by Nigel Middleton as exaggerated.

The Hawk and Owl Trust's conservation officer for the eastern region said the barn-owl population in Norfolk had fallen slightly but this was due to other factors than just the weather and would go back up.

He said: "We are at the bottom of a four-yearly cycle in the vole population, which always means the numbers of barn owls falls as there's less for them to eat.

"It will rise again next year."

Efforts to combat Puffin losses on the British Isles

The island's puffin population has suffered in recent years from an invasion by an alien plant species, which grew out of control and smothered the birds' burrows, leaving them unable to lay their eggs, driving them away from the island.

Tree mallow, a Mediterranean species which can grow up to three metres tall, is believed to have been introduced to the Bass Rock in the 17th century for medicinal use. It is thought that warmer weather, as a result of climate change, has helped the plant to spread at the puffins' expense.

Balearic Shearwaters affected by Climate Change


"Many people believe that because Balearic Shearwaters nest in the Mediterranean, they must love warmth. However, they leave the Mediterranean in mid summer and head north through the Bay of Biscay towards relatively cool British waters. They are cold-water specialists, but with climate change warming the oceans, the seas are becoming less productive, and we believe birds are moving ever further north to find sufficient food," explains Carles Carboneras, a seabird expert with SEO/BirdLife, the BirdLife partner in Spain.
