Global warming changing birds' habits

When it comes to global warming, the canary in the coal mine isn't a canary at all. It's a purple finch.

As the temperature across the U.S. has gotten warmer, the purple finch has been spending its winters more than 400 miles farther north than it used to. Read More...

Global warming affecting migratory birds, says Indian ornithologist

Many migratory birds are now missing out on vital foods as trees are bearing fruit earlier than the scheduled time due to global warming widely blamed by scientists on emissions from burning fossil fuels.

Echoing a fear over the diminishing numbers of birds due to this imbalance, Indian ornithologist Satish Pandey said, an imbalance was creeping in the cycle of arrival of migratory birds and availability of food to them. Read More...

Record Numbers of Ring-neck Parakeets In the UK Could Be Due to Climate Change

Parakeets were first reported in the wild in England in small numbers in 1969 and are thought to have become established because of persistent escapes or releases of pets.

The BTO counted 1,500 in 1996. A further study estimated numbers exceeded 6,000 in 2002.

John Tayleur, of the BTO, said the species is thriving in warmer temperatures brought by climate change and could now be up to a record 20,000. Read More...

No Room at the Top
Climate change forces birds to live at higher and higher altitudes—until there’s nowhere to go
Just seven years ago, climate change wasn’t listed as a potential hazard in Threatened Birds of the World. Now it gets its own heading in the annual book, and with good reason: a new study finds that climate change may trigger the extinction of 30 percent of land bird species by the year 2100.

Microsoft bird-watching in the name of climate change

Avocets Arrive in Britain three weeks early
February 2008. Four Avocets have returned to the Wildfowl & Wetlands Trust’s reserve at Martin Mere in the UK at least three weeks earlier that usual, making this the earliest record in Lancashire of a returning group of summer wading birds for breeding.
This is also yet another clear indicator that climate change is affecting the migration patterns of birds.

Saltmarsh Sparrow May Find Itself In Harm's Way

Global warming could threaten dependency on local coastal habitat
Though perhaps not as dramatic as polar bears drowning in rising Arctic seas and melting ice, the perils of a little sparrow that depends on the salt marshes of southeastern Connecticut for nesting could be a local indicator of the effects of global warming.

"This could be the first Connecticut species to go extinct if sea levels continue to rise as they are,” said Milan Bull, senior director of science and conservation at the Audubon Society. “With global warming and sea-level rise increasing, our coastal salt marshes are at great risk, very great risk."

Climate Change and the Redstart

Early environment may be key to migration location in the American Redstart according to a study by the University of Maryland and Smithsonian Migratory Bird Center of the National Zoo.
While these redstarts appear to be thriving today, the research team says their findings point to the need to consider conservation measures in the winter habitat.

"The models predict increasing drought in the Caribbean," says Studds. "Rain is very important to these birds. If their winter habitat gets drier and their departure dates get later, populations in southern areas could see big declines." Read More...

Birders, try Bigby!

This is a low-key, friendly bit of birding rivalry that is not especially original but which seems appropriate in these days of carbon emissions and climate change. If you have ever felt even a tiny bit guilty about driving or flying to see a good bird (or several) why not join us in a year of carbon-neutral birding? Read More...

This is about more than just incrementally reducing carbon emissions. Its about birders being leaders in creatively finding new ways to carry on in a changing world.

Hawk Migration and Climate Change

Scientists Look To Protect Species From Climate Change
Every autumn since 1983, an annual ritual on what birders call "Hawk Hill", in the Marin Headlands, takes place.

They point binoculars and scopes to take a census of nineteen species, roughly 40,000 birds a year.

The birds have flown this route long before the Army was here, or people.

In fact, their patterns trace back to the last ice age.

Now, as the climate changes again, Allen Fish of the Golden Gate Raptor Observatory wonders how it affects these creatures at the top of the food chain.

This year, they'll look closely at the rough legged hawk, which travels all the way from the arctic.

The numbers show that in the past twenty-five years.

The rough legged hawk has arrived five days later, which may not sound like much.

"It might be a statistical blip or a trend with serious implications because nature is interconnected.

"We're talking about is a potential to desynchronize a huge range of biological events," said Allen Fish, Golden Gate Raptor Observatory. Read More...

Global Warming and changing Bird Behavior
According to an article in the Cleveland Plain Dealer, several ornithological researchers suspect global warming is leading to changes in bird behavior, namely in regards to bird distribution, population and migratory patterns.

The American Bird Conservancy predicts doom for more than half of the migrating species in the Great Lakes region if warming continues at its current pace from a report issued in its publication titled "A Birdwatcher's Guide to Global Warming."

Here is just a sampling of some of the behavioral changes that are being noticed in the Midwest.......

--The Northern Mockingbird, more of a southern bird, has expanded far into the upper Midwest.
--Mississippi Kites nested in southern Ohio recently, which is the farthest north ever recorded.
--Cerulean Warbler population is down 70% over the past 25 years.
--Orioles and Black-Capped Chickadees are becoming much more common in northern areas, while diminishing on the southern end of their normal range. read more...

Birds' changing migration patterns due to global warming
For Lake Erie birders, this prediction sounds, well, a little eerie.

Bird threatened by climate change

A rare game bird which recently made a comeback in Wales could be wiped out by climate change in just 20 years, according to a new report.
Black grouse numbers dropped to 131 active males in 1997, but rose to 247 by 2005.

But the species faces extinction in Wales if global warming continues at the current rate, research suggests.

Snow Goose Explosion

A large increase in the Snow Goose population in the Stillaguamish and Skagit river valleys is creating problems for farmers:
And the population could rise even more. Unusually warm temperatures in the birds' breeding habitat on Wrangel Island, in the Russian Arctic, have led to more chicks hatching and surviving.

Davison said the island's warm temperatures may be a result of global warming. If so, conditions could grow still milder and bring yet more geese.

Struggling Seabirds

West Coast seabirds are dying, apparently from a lack of food -- and some researchers think the phenomenon may be linked to global climate change.

This is the third year that scientists have found unusually large numbers of marine birds -- mainly common murres, but also rhinoceros auklets and tufted puffins -- washed up on beaches in California, Oregon and Washington. In 2005, the first year of the phenomenon, large numbers of Cassin's auklets also died. ...

Sydeman said the anomalies could be linked to global climate change.

"What's clear is that during the past decade, there's much more variability out there than there was during the preceding 40 years," he said.

Ducks on the Chesapeake

Batt said climate change is throwing the bird world out of whack. Like the canvasbacks, which are wintering farther north, mallards that once spent the cold months in Mississippi and Arkansas are instead spending the season in Missouri and Kansas. The blue-winged teal, which typically rides out the winter in Cuba and South America, has switched locales to Louisiana and Texas.

"Climate change is the story," Batt said. "Nobody knows how this is all going to shake out in the long run, and each species is a little different."

Birds Shift North

More bird species in the United States are ranging farther north and even staying there for the winter in a possible sign of adaptation to global warming, ornithologists and conservation groups say.

Some indicators come from the recent Great Backyard Bird Count, which found more swallows, orioles and other common birds in uncommon locations.

"We've got Baltimore orioles in 14 states, orchard orioles in five different reports and Scott's oriole in Pennsylvania. They shouldn't be here. They should be way south," says Paul Green of the National Audubon Society, co-sponsor of the count with the Cornell Lab of Ornithology.

Scientists cannot say yet whether the birds' movements are climate-related or short-term reaction to storms, hot or cold spells, disruption of habitat or food availability. However, the results of the four-day tally performed in February are "a tempting indicator of change, which may turn out to be the early stages of the effects of changing climate on bird distribution," Green says. "We won't know for certain until we have another 20 years of data."

The Theme for International Migratory Bird Day 2007 is "Birds in a Changing Climate"

Birds have long been indicators of envionmental change, sounding the alarm about the impacts of pesticides, polluted water, and the loss of contiguous forest. While IMBD continues to promote the joy of birds, it will also tackle a challenging, yet pertinent topic in 2007 - climate change.

The reactions of birds to weather have long been noted. For hundreds of years, farmers have used the arrivals of migratory birds to make decisions about planting crops. Changes in the movements of some species is just one indicator of the warming of the Earth's atmosphere. Today, as the rate of warming increases, scientists are exploring how climate change will affect birds and how we can reduce our impact.

Birds arrive early in the UK

Move over cuckoos. In this era of global warming the chiffchaff has become the harbinger of spring.

The first sightings of chiffchaffs in Britain this year were reported yesterday prompting bird watchers to proclaim that spring has started.

It joined a wealth of indicators that spring has well and truly arrived, including frogspawn in northern Scotland, butterflies by the score and flowers everywhere.

This time last year the country was still in the grip of snow and Arctic winds.

Yesterday Gravesend in Kent recorded 18C (64F), the highest temperature of the year so far — whereas in 2006 it was late April before similar warmth was felt.

Climate Change and Birds on New Hampshire Public Radio

My friend Mary is quite enthralled with cardinals. It’s not only how handsome the bright red males are or how dedicated they are to their less colorful mates, but because they are a relatively new phenomenon for her. When Mary first moved into her New Hampshire home more than 60 years ago, cardinals were rare.

But now these pretty birds are found throughout the Granite State from Brookline to Berlin. The reason has been attributed to the increase in bird-feeders but can also be linked to our increasingly milder winters. read more...

Is this bird a product of global warming?

A WILDLIFE sanctuary has rescued a two-week-old blackbird, the first time
such a young bird has been found at this time of year.The fledgling was
discovered in a garden in South London and brought to the Willow Wildlife
Sanctuary in Chislehurst by a concerned bird lover.Eddie Williams, who runs the
rescue service said: "This has got to be a first, and it must be because of the
mild weather. It takes 13 days for these birds to incubate, and then another 13
to 14 days to fly after the egg has hatched."The egg must have been laid around
January 20 at the latest, as the bird is still a few days away from growing the
full tail it needs to fly.Mr Williams will keep the bird for up to two weeks to
ensure it is fit and healthy when it is released.

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.

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...

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.

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.
