It is a question people have pondered for centuries: how do migrating birds
navigate between breeding and wintering grounds? Do they have some genetic GPS
to steer them along time-honoured routes, or do they learn the way from parents
or elders in migrating flocks? New research shows that, in the case of the
endangered Whooping Crane of North America, the birds do learn routes from older and more experienced companions — and all of them become better at navigating with age and experience.

University of Maryland ecologist Thomas Mueller and colleagues took advantage
of eight years of detailed migration data compiled on birds bred in captivity
and released in Wisconsin's Necedah National Wildlife Refuge for a journey to
their Florida breeding grounds. Flying groups that include a migration-savvy
seven-year-old crane veer off course 38% less often than groups in which the
oldest birds are only a year old, according to an eight-year study of Whooping
Crane migration between Wisconsin and Florida. On average, the one-year-olds
that don't follow older birds veer off the flight path by 60 miles (97km). But
the cranes' migration ability improves steadily with age, the study shows.
Groups with even one of these older birds deviate less than 40 miles (64km), on
average, from the most efficient route.

 Other likely variables for navigation success, including gender and the size
of flying groups, appeared to make no difference in the results. Mueller, a
co-author of the study, and his team theorized that the older birds recognize
landmarks better and may also know how best to cope with bad weather — two
skills they apparently pass on to the young birds that follow their lead. "As
the oldest bird in the flying group gets older, it seems that there's dramatic
improvement in its migratory efficiency for about the first five years," Mueller
said. "There is a very big difference if the oldest bird in a flying group is
one or two years old or if it's five or six or seven years old. A bird can be
pretty young and still have great success," he added, "as long as it flies with
a bird that is pretty old."

What's new?
Previous studies have suggested that learning plays some role among migrating
species. However, as Mueller cited, what is new here is that learning takes
place over a number of years and the older birds are crucial to the development
of the younger birds. Mueller explained: "That was difficult to look at before
because the data simply didn't exist. Usually tracking data on animals lasts for
a year or two years if you're lucky."

As part of unprecedented efforts to save and reintroduce the species,
scientists collected data to gauge the success of breeding, training, and the
birds' subsequent 1,300-mile (2,100km) migration. Individual birds were
identified and tracked with satellite transmitters, radiotelemetry, and human
observers. "Usually you don't even know if a bird is two or three or four years
old," Mueller continued. "There are lots of [previous] comparisons between
juveniles and adults, but here we had the full progression of many years as well
as the information of how old the birds were, how they were related to one
another, and exactly where and when they migrated."

What does this mean?
The Whooping Crane research is important new evidence showing how bird
migration is, at least in part, a learned skill. But it won't put to rest the
long-running debate on the respective roles played by genetics and social
learning.

 In fact, Mueller said, the study suggests an interesting combination of
genetics and learned behaviour at work. It begins when the time comes for the
cranes' first autumn flight to their southern wintering grounds and the
captive-bred animals are actually guided by humans who fly ultralight aircraft
all the way to Florida. "If you think about even that initial migration, it
needs to be at least somewhat learned," he explained. "They may have a natural
tendency to migrate in the fall, but we don't think many would get anywhere
where they could survive without some training."

 But genetics do begin to play a more easily visible role on the return trip,
he added. "Then after they've been shown the route once, in the spring they know
it's time to initiate a return and there's a genetic component in play there.
Because nobody has showed them this, so it's genetics combined with the learned
knowledge from the trip south in the fall."

 What's next?
Co-author Sarah Converse, a research scientist with the U.S. Geological
Survey's Patuxent Wildlife Research Center, has worked extensively with the
Whooping Crane Eastern Partnership, which runs the eastern migratory population
reintroduction program. She said: "Our results suggest that an effort to restore
Whooping Crane populations isn't just an effort to restore a biological
population, but also an effort to restore a culture, where knowledge is
transmitted across generations via learning, rather than genetics."

 "We can imagine that the low breeding success that we are currently
struggling with in this reintroduced population might actually improve over
time, with increased experience and learning of appropriate breeding behaviours.
For example, maybe chicks learn from their parents how to themselves be
successful parents. Overall, these results suggest that patience may well be
important if we hope to restore migratory Whooping Cranes to eastern North
America."

Conservationists in Somerset are celebrating the news that the Avalon Marshes
  has had its best year ever for rare breeding herons.

Following the first  British nesting Great Egrets last year in the marshes, this summer has seen two  pairs successzfully raise young; one pair again at Natural England’s (NE)  Shapwick NNR (producing two fledglings) and a second pair within the boundary of  the RSPB’s Ham Wall nature reserve (producing three). The Avalon Marshes is a  huge wetland recreation site to the west of Glastonbury, managed jointly by NE, Somerset Wildlife Trust (SWT), Hawk and Owl Trust (HOT) and RSPB.

Ham  Wall RSPB has also been hosting a nesting pair of Little Bitterns. This is the
  only known British breeding location for these remarkably shy and diminutive
  herons, and this year two chicks fledged. In addition to this, Bittern itself
  has had yet another amazing year across the marshes, with as many as 33 booming  males being heard. The area is now one of Britian’s hotspots for this rare and remarkable bird.
Alongside the bitterns and egrets, the area has also
  provided a home for four pairs of Marsh Harrier, which produced 13
  young.

Ray Summers, RSPB warden for Ham Wall said: “We are all
absolutely  delighted. Since we took on the land at Ham Wall back in the mid
1990s, we’ve  been working hard to recreate a pristine wetland. To have all
these nesting  herons and harriers is a fantastic seal of approval for the work
we’ve done, and  really demonstrates the quality of the site for
wildlife."

Mark Blake,  Reserve Manager for SWT, said: ”It has been an
exciting year on the Avalon  Marshes and we are delighted to see Marsh Harrier
breeding at Westhay Moor for  the second year. The habitat creation and
management being carried out by the  partners is going from strength to strength
and we look forward to further  breeding success in future.”

Chris Sperring MBE Conservation Officer for  HOT said: “The Avalon Marshes just get better every year. The success is down to  a wonderfully balanced and organised
partnership, particularly heartening when  we see so many new species
establishing, and some old friends like the Marsh  Harrier on the rise as
well.  The careful management also creates a very human  experience, as I
found out recently while on a footpath with a Kingfisher  hovering less than 3
metres from me.”

A rare sighting of a marked Spoon-billed Sandpiper on migration was reported last weekend from Rudong mudflats north of Shanghai. The critically endangered bird was identified by a lime green plastic flag on its leg marked '01' that was
attached by scientists from Birds Russia on its breeding grounds this
summer.

Conservationists know that this bird 'Lime 01' fathered six fledglings this
summer — three that were hand-reared by conservationists and three that he
raised himself — which is 10 times the average for the species.

 In all, this summer sixteen hand-reared Spoon-billed Sandpiper fledglings and
eight adults were marked with uniquely inscribed plastic leg flags. Birdwatchers
are being asked to report all sightings of Spoon-billed Sandpipers.

Coordinator of the Spoon-billed Sandpiper Task Force, Christoph Zöckler,
said: "The Rudong mudflats are an extremely important stop-over site for the
Spoon-billed Sandpiper to rest and feed and it is very exciting news that our
Russian breeding birds have been sighted there. Unfortunately these mudflats,
like much coastal wetland along the East Asian–Australasian Flyway, are
threatened by the development. Alongside illegal trapping and hunting, it has
pushed these birds to the edge."

 WWT Head of Species Conservation Department, Baz Hughes, said: "This is why
we're taking extreme measures to prevent its extinction: hand-rearing chicks to
boost numbers, but Spoon-billed Sandpipers rely on the help of so many people.
Reports like this are only possible thanks to the support of birdwatchers
throughout Asia and are an invaluable part of its conservation."

Rudong mudflats are the most significant known staging post in China for
Spoon-billed Sandpipers, where 106 individuals were counted last year in
October. Demand for land is high in the region, which is only 150km from
Shanghai, and land has already been reclaimed from the marshes at Dongling to
the southern end.

Pavel Tomkovich of Birds Russia, who caught and marked the bird with Nikolai
Yakushev, said: "When I marked 'Lime 01' I wondered if anybody would ever see it
on its travels, almost a quarter of the way round the world, as looking for
Spoon-billed Sandpipers can be like looking for a needle in a haystack. Looking
for marked birds is even more difficult as we were only able to mark eight adult
birds with these unique flags. Thanks to the reports of local birdwatchers,
we're learning their stopover points."

 'Lime 01' was seen leaving the breeding grounds on 4th August and was seen
5,000km away at Rudong on 31st August. Spoon-billed Sandpipers can cover as much
as 1,000km per day, leaving around three weeks during which it may have been
staging elsewhere

BTO Head of Projects, Nigel Clark, said: "We've known for a few years that
they stop at Rudong mudflats and we hope to be able to protect it. But our
calculations indicate that 'Lime 01' probably stopped somewhere else for up to
three weeks before reaching Rudong. We want to find out where that is in case it
is under threat."

 Zhang Lin of the "Spoon-billed Sandpiper in China" Team said: "The first
Spoon-billed Sandpiper arrived at Rudong about two weeks ago since when I have
been regularly scanning the increasing numbers of waders at the high-tide roost
at Rudong. When I glimpsed a bird on 31st August that looked like it had a lime
green leg flag I knew something exciting was in front of me. On closer
inspection it turned out to be 'Lime 01'. I was over the moon as this is the
first time that one of the birds marked in 2013 has been seen in China. It is
amazing to see how these little but critically endangered birds are connecting
our key sites along the flyway between Russia and China. They are very important
as they allow us to track whether efforts to save the species are working."

For first time since Middle Ages, Common Cranes have raised young in Scotland, on a farm whose precise location has been withheld.

The striking wading birds have successfully raised two chicks within the last two years in North-East Scotland, said the RSPB, indicating conditions could be right for the species to recolonise Scotland.

Small but increasing numbers of the migratory birds, which spend summer in northern Europe and winter in southern France and Spain, have passed through Britain in recent years and a small breeding population became established in Norfolk in 1979, with further breeding in Suffolk. However, these are the first confirmed successful nests north of the border for hundreds of years.

Common Crane once bred regularly in Scotland but died out about 400 years ago, primarily due to being hunted for mediaeval  tables. Habitat loss and a slow reproductive cycle may have also contributed to the species' disappearance.

The species, which favours large wetland areas such as lowland peat bogs with an abundance of pools, appears to be benefitting from farming methods in the area which provide plentiful invertebrates, grain and other foods, as well as the right conditions to breed and successfully raise chicks.

Stuart Housden, Director of RSPB Scotland said: “We are stunned and delighted to see that Common Cranes have bred successfully in Scotland. These charming, elegant birds have a strong place in our myths and history and are a delight to see, particularly during the breeding season with their 'dancing' displays. They undertake regular migrations and small numbers have turned up on the east coast of Scotland in recent years, raising hopes of a recolonisation. Last year a pair reared one chick, followed by a second chick in 2013.

“Thanks to the co-operation of farmers in the area, the conditions appear to be right for cranes to take up residence and it is possible that more will choose to re-establish themselves in the country in future.

“We have been working with local farmers, landowners and the community to monitor these fantastic birds. Despite their size and flamboyant breeding displays, cranes are secretive birds and are very sensitive to disturbance and  we ask that they be given space and peace so they may establish a breeding population in Scotland.”

To minimise risk of disturbance, the exact location of the nest site has not be revealed. The British breeding population stood at 17 pairs in 2011. In addition to natural re-colonisation, a re-introduction project began in 2010 on the Somerset Levels, the result of a partnership between RSPB, WWT, Pensthorpe Conservation Trust and Viridor Credits.

RSPB’s Loch of Strathbeg nature reserve, a major coastal wetland near Fraserburgh, is visited by cranes on spring migration and offers the best opportunity to see them doing their ‘dancing’ displays. 

The safety tens of thousands of swans and geese in the UK could be improved by new research into collisions with power lines, which started this week with the installation of more than 150 special bird diverters in Lancashire.

Flying collisions are the most commonly recorded cause of death for swans, whose size means they have poor manoeuvrability in flight. Bird diverters are special attachments to the lines that help make them stand out to birds in flight. For the first time, a partnership between Electricity North West, Lancaster University and the Wildfowl & Wetlands Trust (WWT) is studying the efficiency of different types of diverter, alongside agricultural, weather and landscape factors that affect birds' flights. The study area around WWT Martin Mere in Lancashire is the winter home of 30,000 Pink-footed Geese and 2,500 Whooper Swans and has been identified as a sensitive area for collisions.
Dr Eileen Rees, Head of UK Waterbird Conservation for WWT, said: "Tens of thousands of migratory geese and swans make the UK's wetlands their winter homes. Collisions with power lines are a major cause of death for them, so WWT is delighted to be working with Electricity North West to make Lancashire, and the UK as a whole, a safer place for them. Through this innovative partnership we aim to gather evidence for solutions that work in our modern landscape. As well as reducing the risk to swans and geese, the results of the study should help electricity suppliers throughout the UK provide their service with fewer unnecessary interruptions."

Steve Cox, future network manager for Electricity North West, added: "We hope that the diverters and our subsequent research will go on to help birds and electricity customers across the UK. By working closely with WWT Martin Mere we discovered this was a sensitive section of the network as it was located in a known flight path and we are delighted to be able to help protect these wonderful birds. By limiting the chances of any collisions, the special diverters will also reduce any possible impact on customer power supplies."

Dr Ian Hartley, a Senior Lecturer at the Lancaster Environment Centre at Lancaster University and a behavioural ecology expert, commented: "This is a great opportunity and we are very pleased to be working with new partners on a project of such high calibre which is going to have a large impact on the area around where the geese and swans winter. One of our Master's students will work on the project for a year and our input will be to add knowledge on the analysis and geographic information systems aspects."

Throughout this winter, the study will closely observe the flight behaviour of geese and swans in and around WWT Martin Mere Wetland Centre. It will determine the importance of features such as tree lines, the choice of crops and the wind direction on the birds' choice of flight line and height.

Critically endangered Spoon-billed Sandpiper fledglings have increased
in number by a quarter in 2013, after conservationists intervened to hand-rear
chicks. As few as 100 breeding pairs remain in the wild, rearing just 60 young
between them each year on average. The 16 additional hand-reared young from this
year are a significant boost for the species, which is on the verge of
extinction.

WWT Conservation Breeding Officer Roland Digby commented: "The breeding
season in Russia is short and brutal for Spoon-billed Sandpipers. Each pair is
lucky to get even a single chick as far as fledging. Normally, that's life, but
right now the Spoon-billed Sandpiper needs a lifeline to keep them from going
under."

 Experts from the Wildfowl & Wetlands Trust worked with Russian scientists
to source eggs from breeding pairs soon after being laid. Taking the eggs
prompted each breeding pair to lay a further clutch, which they were left to
rear themselves. One pair produced a total of six fledglings this year — no less
than ten times the average.

The tiny fledglings now face their first 8,000-kilometre migration to Myanmar
and Bangladesh. Along the way they will struggle to find undeveloped coastal
mudflats to rest and feed, and on arrival they risk being trapped in nets.
Birdwatchers in Asia are being asked to report any sightings of Spoon-billed
Sandpipers. All hand-reared birds have a tiny coloured flag attached to one
leg.

 Intervening to increase breeding productivity in wildlife like this is known
as headstarting. It is a short-term strategy and Tim Stowe, RSPB Director of
International Operations, said: "Having been part of an expedition to look for
additional Spoon-billed Sandpiper breeding sites, I can appreciate that giving
these amazing birds a helping hand through headstarting will help deliver
short-term conservation benefits."

Conservationists are tackling the problems of illegal trapping and habitat
loss along the species' flyway. It is calculated that headstarting Spoon-billed
Sandpipers will increase the number returning to breed as problems are
addressed, allowing the population to stabilise and recover more quickly.

Recent surveys on its coastal Patagonian wintering grounds indicate that the
Endangered Hooded Grebe Podiceps gallardoi has declined by 40% in
the last seven years and this, along with alarming new threats detected on its
breeding grounds during 2011, indicate action is now urgently required to
prevent the rapidly increasing threat of its extinction.

 In response to these worrying findings, Aves Argentinas (BirdLife in
Argentina) has mounted a wide-ranging offensive to protect this
highly-threatened migratory species from further decline. In support, we are
launching an international online appeal through the BirdLife Preventing
Extinctions Programme to help fund the urgently required conservation
action that they have already begun.

 Please click here to visit BirdLife International's 
appeal page and see a video of breeding Hooded Grebes filmed by our
conservation team last week.

  Discovered only as recently as 1974, Hooded Grebe has declined by as much as
80% in the last 30 years and as a result of surveys conducted in 2006 and 2009,
the species was uplisted by BirdLife to Endangered on the IUCN Red List in
May 2009. Recent counts on the wintering grounds last year, suggest the decline
is steepening further.

 “Our teams started to become really worried when we realised that
there was more than one cause to tackle if we were to conserve the Hooded
Grebe”, said Gustavo Costa, President of Aves Argentinas.

In many of the lakes in the grebe’s core distribution, exotic trout have been
introduced for industrial fish production. “Trout rearing has reached the most
isolated places, and this industry is threatening not only the future of the
grebe but also the rest of the wildlife present in those environments”,
Gustavo Costa added. Also evident are the increasing numbers of Kelp Gull
Larus dominicanus, a known predator of the grebe that has benefited
from both the fish industry and poor waste management at human settlements.

As if these problems were not already enough to push this struggling species
over the edge, a breeding colony which Aves Argentinas was studying at Laguna El
Cervecero, Santa Cruz Province in March 2011, was devastated by a sinister
and ferocious invasive pest that is now advancing in western Patagonia: the
American mink, Neovison vison. More than 30 breeding adult Hooded
Grebes were found killed by mink at this one site, and a further 40-plus eggs
were abandoned.

 “This was one of the saddest days in my life as a naturalist, but at least it
meant that we had discovered another reason for the Hooded Grebe’s decline – and a very frightening one at that – that could allow us to implement suitable
management actions in the field”, said Kini Roesler, a field biologist who is
doing his PhD on the species.

 As part of the immediate conservation action Aves Argentinas is coordinating,
a team of scientists and conservationists including staff from Aves Argentinas,
Ambiente Sur and CONICET are currently in the field attempting to prevent
predation at several known colonies this breeding season. Measures to
control mink and reduce predation by gulls are being prioritised and wherever
breeding populations are located, they plan to set up ’round the clock’ watches
to protect the nesting birds.

Climate change is also a major threat to this species and its habitat: anecdotal reports suggest that recent winter snowfall has been much reduced, without a corresponding increase in precipitation at other times. Many of the lakes surveyed last year were found to be dry or becoming clogged with silt as a result of the general desertification of the region, leading to changes in the composition of the water.  Water levels at known breeding sites were 2-3 m lower than in previous years.

 Recent investigations indicate that wind gusts have also significantly
increased in recent decades. Unseasonably strong winds have caused around
50% of all breeding attempts to fail in the last three years. At other
times this threat would be marginal; with adult mortality naturally very low,
the species may be adapted to survive a succession of poor breeding seasons.
But, with numbers now so reduced and still falling so rapidly, the loss of
entire breeding colonies to wind damage could have a much greater impact.

 A stark shadow was cast over Aves Argentinas’s findings when, in May 2010,
the Alaotra Grebe Tachybaptus rufolavatus of Madagascar was declared extinct. This was the third known grebe extinction since the last quarter of the 20th Century, after the Colombian Grebe Podiceps andinus and Atitlan Grebe
Podilymbus gigas, and followed news that the Critically Endangered Junín Grebe Podiceps taczanowskii, which already had a population of fewer than 250 individuals, had suffered a further population decline.

 “This is why we are developing an action plan for the Hooded Grebe, that
involves research, pest control and advocacy at every level”, said Dr. Andrés
Bosso, Director of Aves Argentinas’ International Co-operation Programme.
 An initial meeting to develop a species action plan took place at Aves
Argentinas’s headquarters, in July 2009, and brought together specialists from
Ambiente Sur, Aves Argentinas, and Fundacion Vida Silvestre Argentina who are
now working closely together.

 “We need to strengthen the protected areas system in the region”, Andrés
Bosso added. “Eight Important Bird Areas (IBAs) contain the species, but only
one is fully protected.” Laguna Los Escarchados, the site where Hooded Grebe was
discovered in 1974, was declared a reserve in 1979, but is now known to
only hold a marginal population. Key breeding lakes in the core of the
grebe’s range lack any kind of legal protection, though the population
stronghold on Meseta de Strobel is still afforded some protection by its
remoteness and inaccessibility.

Aves Argentinas has been appointed official BirdLife Species Guardian for Hooded Grebe and is seeking funding for a range of urgent actions that are already in progress to  ensure the survival of the species. These include implementation of summer and  winter surveys and predator control in 2012, 2013 and 2014, embracing the  entirety of the Buenos Aires, Asador, Las Vizcachas, Viedma, Cardiel and Strobel  plateaus, the Coyle and Gallegos estuaries, and any of the plateaus reachable in  winter. Surveys are also now being carried out on previously unsearched plateaus.

 A number of local conservation agents are also being assigned to the
species’ breeding and wintering grounds to execute a monitoring plan and
implement the needed conservation measures.

 The programme to eradicate mink, control Kelp Gull numbers on the breeding
grounds, and help protect breeding sites from strong winds has already begun in
earnest. Farm-workers will be encouraged to become local “Hooded
Grebe Guardians”, monitoring the presence or absence of the birds, and give
Aves Argentinas early warnings of potential new threats to the species.
Conservationists are also seeking agreements with landowners on the plateaus to
purchase and/or protect their properties as private reserves.

 Ringing/banding and satellite tracking will be used to improve knowledge of
the birds’ movements, and determine where juvenile Hooded Grebes spend the
winter.

 A national campaign to raise awareness of the Hooded Grebe and its
predicament among the Argentinian public is also planned, with an additional
goal of having the bird declared an official National Monument. A team from
Aves Argentinas is currently in the field overseeing the filming of a Hooded
Grebe documentary which will be used in this campaign. This production is
being supported by the Argentine Ministry of Tourism.

 There is clearly much to be done if the fortunes of the remarkable Hooded
Grebe are to be turned around. A robust plan is in place and work has already
begun but significant funding is now urgently required to deliver this ambitious
project and achieve long-term success.

 Every little helps and every one can join in. If you would like to help save

original discovery, please click here to make a donation online

Twenty critically endangered Spoon-billed Sandpiper chicks have hatched under expert care in the Russian Far East. Conservationists took the eggs from the wild, in order to protect them from extreme weather and predators. The first hatched early last Wednesday morning and they continued until the last hatched on Sunday evening.

Numbers of Spoon-billed Sandpipers have plummeted in recent years because of the destruction of wetland habitats and the effects of illegal trapping along their migration route. While tackling these problems, conservationists are boosting the productivity of the remaining breeding pairs by taking eggs from the wild, hatching and rearing them in captivity and releasing them once they have fledged. WWT Head of Species Conservation Dr Baz Hughes said: "This is conservation at the edge; it's risky work, in difficult conditions, but my colleagues have proved yet again how incredibly experienced they are at rearing endangered birds. Breeding season is brief and brutal for Spoon-billed Sandpipers in the wild, but by intervening like this we can help rear five times as many young and help the population stabilise. But it's expensive to work in the remote Russian Far East and it's only possible due to the financial support we've raised for this charismatic bird."

RSPB's Head of International Species Recovery Team Dr Rob Sheldon added: "This delightful and engaging bird has been brought to the edge of extinction by rampant habitat loss and severe hunting pressure, which are now being recognised and tackled. The conservation breeding programme is but one part of an international effort to save Spoon-billed Sandpipers. Head-starting is an innovative additional technique that gives the population a helping hand at this critical stage in our attempts to prevent their extinction."

Chief Executive of Birds Russia Dr Evgeny Syroechkovskiy commented: "We have come so close to losing the Spoon-billed Sandpiper. Each of these twenty chicks represents a bit more hope for the future of the species. I am very proud of the hard work by our team of fieldworkers, aviculturists and researchers."

Jean-Christophe Vié, Director SOS — Save Our Species, said: "At SOS we are delighted to support this project and its innovative conservation methods. The head-starting programme had already delivered meaningful results in 2012 and the news of this additional batch of hatchlings in Chukotka fortifies hope for the Spoon-billed Sandpiper's future. It is rewarding news not just for the experienced team out there but for all the unsung heroes who strive — often in remote corners of the world — to save our threatened species."

Foxes, skuas and feral dogs take eggs and chicks from the ground-nesting birds, and sudden changes in the weather can be fatal. Studies show that on average each pair lays four eggs per year but raises less than one chick. Artificial incubation and captive rearing increases that to more than three and, by taking eggs within days of them being laid, the birds naturally start again with a second clutch that they incubate and raise themselves. The approach, known as head-starting, is a short-term tactic. It increases the number of birds approaching breeding age as conservationists tackle the problems of illegal trapping and habitat loss, hopefully enabling the species to stabilise and recover more quickly.

The team is blogging about their progress at www.saving-spoon-billed-sandpiper.com.

RSPB Scotland are appealing for information after a Black-throated Diver, one of Scotland's rarest birds, was found dead on the shore of Loch Gowan, near Achnasheen (Highland). The bird was discovered by local biologist Jim Raffell and was reported to the RSPB.

A post-mortem, carried out by Scottish Agricultural College vets on behalf of the nature charity, revealed that the bird had been shot by a "high-velocity projectile". Police enquiries have been unable to identify a suspect. The Black-throated Diver breeds on freshwater lochs, wintering at sea. It is a very rare breeding species in the UK, with the population (of around 240 pairs) confined to the north and west of Scotland. They are known particularly for their elegant summer plumage, haunting calls and their tendency to mate for life. This bird killed is believed to have been one of a breeding pair.

A spokesman for RSPB Scotland said: "This is an appalling and inexcusable crime. Black-throated Divers are stunning and very rare birds, with their UK stronghold in the Highlands of Scotland. It is truly shocking that one of these birds has been deliberately targeted, with a complete disregard for both the law and the rarity of this species."

Mr Raffell, a fisheries biologist with the Scottish Government, added: "To find a dead Black-throated Diver is very sad, but to then be informed that that it had been shot caused me much upset and made me very angry. How any person could deliberately shoot such a beautiful, enigmatic and uncontroversial bird is outrageous. I hope that by raising awareness of this crime, it will never be repeated."

The news comes hot on the heels of a press release, issued last week by RSPB Scotland, that demonstrated how artificial rafts covered in vegetation were helping to raise the breeding population. Since tethered rafts were introduced to lochs in the late 1980s, RSPB Scotland said numbers of breeding pairs had risen from 180 to 240 in 2012. You can read more on that story on the Birdwatch website.
