Instead, Glue believes that the main reason why the cuckoo is in crisis is to be found not in the UK but thousands of miles away in Africa. "We know that the cuckoo overwinters in East Africa, which is increasingly being hit by drought as a result of climate change and which is making conditions very difficult for both wildlife and people in the region," he says.

Birds are finding it increasingly difficult to cope with the changing British climate, the Royal Society for the Protection of Birds (RSPB) has warned.
Milder winters and cold snaps are affecting feeding routines and altering migratory patterns.
As a result, the number of birds counted by participants in January's Big Garden Birdwatch was down, with some breeds hitting a five-year low.

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."

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."

Tim Melling, a Royal Society for the Protection of Birds conservation officer who is based in Yorkshire, says that he heard larks singing in early February. The birds are reacting to unseasonably warm and sunny weather.
Britain is emerging from its warmest winter ever recorded. BBC weatherman Paul Hudson reported that the county's highest ever January overnight temperate, 11.5 degrees Celcius, was recorded at Leeming, a temperature more normal at that time of year for North Africa rather than North Yorkshire.

A CHANGE in climate could be the cause of the early arrival of orange-bellied parrots to the south-west.
Co-ordinator for the South West Orange-Bellied Parrot Working Group, Dianne Davis, said one of the rare birds was spotted with a flock of blue-winged parrots on a property at Killarney last week.

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.

As for the timing of the birds' migration, some suspect that changes in weather patterns could be responsible.
"We're experiencing climate change all over the world," Roth said. "Whether they call it global warming is a whole other issue, but the change in climate is being expressed in delayed migration in the autumn and earlier migration in the springtime." Read More...

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.

Alan Davies, site manager at the RSPB's Conwy reserve, said this spring is the most bizarre he has ever experienced.There has been spring-like activity for weeks, he said. 'This has been the earliest spring ever in the bird world; it is totally unprecedented. It is easily five or six weeks ahead - it's all gone haywire.
'A swallow was spotted in South Wales on February 18, after flying here from the Cape, South Africa. The wheatear and sand martin are already here too. They are very early - it's crazy.
'The black-backed gull that winters in Morocco arrived in huge numbers in February and reed bunting - usually here in April - were sighted on February 20.
'Lapwing are already making their nests ready for breeding. And the bird dawn chorus sounds fantastic at the moment and has already reached the peak levels you would usually expect in April.' Read More...

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...

One of Britain's largest puffin colonies is being wiped out by an invasive plant that is thriving in warmer temperatures brought about by climate change.
In just seven years a colony of 29,000 breeding pairs of puffins on the island of Craigleith, just a mile from the coast of North Berwick, has been reduced to fewer than 3,000. They have been driven to the edge of extinction by a dusky-pink, 8ft flowering plant called tree mallow. Introduced by 18th-century lighthouse keepers and sheep farmers on nearby Bass Rock the woolly-leafed plant is renowned for its medicinal properties and was used as natural bandage. read more...

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.
