Laying video traps for the raptor persecutors - Environment - Yorkshire Post




North Yorkshire is top of the UK league for the illegal killing of birds of prey. Roger Ratcliffe reports.

Catching someone in the act of deliberately killing a bird like a peregrine or a goshawk used to be unheard of.

In the remote uplands of England the culprits were too cunning for police and wildlife investigators.

But like the traps they set to lure birds to their deaths, modern technology is now turning the tables and trapping them.

Hidden video cameras are now being used to ensnare some of the gamekeepers engaged in the slaughter.

Last week a covert filming operation by the RSPB led to the conviction of a gamekeeper at Chesterfield Magistrates Court.

Glenn Brown, 39, of Upper Derwent Valley, was found guilty of seven offences and sentenced to 100 hours of community service plus he was ordered to pay £10,000 costs.

Brown was arrested after an RSPB team filmed him using a cage trap baited with a live domestic pigeon on moorland to the west of Sheffield which is owned by the National Trust but leased for grouse shooting.

The operation was identical to one in the Scugdale Valley of the North York Moors three years ago when three gamekeepers were filmed using live pigeons in cage traps.

Sparrowhawks, peregrines or the much rarer goshawks are the typical victims of such traps.

Having entered to kill the pigeon, the raptors find they are unable to escape and can then be killed by the trap user.

According to the RSPB, North Yorkshire and Cumbria jointly top the UK “league of shame” for persecution of birds of prey.

In 2009, the last year for which figures are available, 27 attacks were reported. In South Yorkshire the total was 12; 11 in the West Yorkshire and four in the East Riding.

PC Gareth Jones, North Yorkshire Police’s Wildlife Crime Coordinator, has no doubts about who is to blame.

“Unfortunately, where there are organised shoots for grouse and pheasants there is a conflict between the shooting fraternity and birds of prey,” he says.

“Let me make it clear that I’m not tarring all gamekeepers with the same brush, because the majority of them are honourable.

“But there are still some rogue keepers who adhere to the Victorian attitude that anything with a hooked beak and claws is the enemy of game birds.

“As a result there are huge tracts of the Yorkshire Dales and North York Moors where there should be healthy populations of birds of prey, yet there are none.”

PC Jones cites hen harriers as an example. They are the bird of prey most associated with heather moorland, but they are now seriously endangered in England.

“We haven’t had a nesting pair in North Yorkshire for about four years.

“The only place in England hen harriers still nest is over in the Bowland area of Lancashire. There, the moors are owned by the Duke of Westminster and United Utilities and they have instructed their gamekeepers that they must coexist with these beautiful birds.”

PC Jones says that five years ago there was an attempt to involve North Yorkshire landowners in the Hen Harrier Recovery Project run by Natural England but it came to nothing.

“I hope that attitudes might change,” he says. “Because estates must surely see that the wider public finds birds of prey so charismatic – as shown by the interest in nesting peregrines at Malham Cove and Scarborough.

“Yes, birds of prey might have a slight impact on grouse numbers but estates will get people coming to stay in the locality, renting their holiday cottages and so on.”

In the past two years, there has been a spate of attacks on goshawks in the North York Moors.

Two were found shot, another was poisoned and there was also a case of illegal nest disturbance.

And earlier this year there were cases of red kites – their success re-introduction to Yorkshire on the Harewood Estate attracted enormous interest and publicity – being found poisoned a few miles away in the Lower Washburn Valley.

Doug Simpson, the coordinator of Yorkshire Red Kite project believes the deaths occurred because the birds ate poisoned baits left by farmers to control foxes and crows.

“It is worthy of note,” he says, “that this roughly coincides with the time when lambs are out in the fields in good numbers, and are vulnerable to attacks from foxes and crows.

“Clearly some individuals are still pursuing the practice of trying to control them with illegal baits.”

The RSPB says that cases of illegal shooting, poisoning and trapping have increased every year for the last decade.

The society’s conservation director, Dr Mark Avery, believes that nearly 2,000 incidents reported to the police since 2003 represent a fraction of what takes place.

“The conflict with land managed for the shooting of game birds remains the main problem for birds of prey,” he says.

“Particularly the upland grouse-shooting estates in northern England and Scotland. The main species affected are golden eagle, white-tailed eagle, hen harrier, goshawk, peregrine and red kite.”

The society is concerned the shooting industry appears unable to self-police, says Dr Avery and he believes new legislation is required to make the managers and employers of those committing these crimes legally accountable.

Options such as so-called “vicarious liability” – that holds employers accountable for crimes committed by their staff – and removing the shooting rights of convicted individuals and errant estates need to be considered, he says.

“These would provide a significant deterrent without imposing a burden on legitimate shooting interests.”

Reports of gamekeepers being convicted by courts cause great frustration for those involved on game shooting estates who conduct their affairs wholly within the law and also see their work as benefitting not just game birds.

Control of predators like stoats, weasels, rats and crows on grouse moors have been shown to produce healthy populations of wading birds like curlew, redshank, lapwing and golden plover.

Since 2007 the Game and Wildlife Conservation Trust (GWCT), which works closely with shooting estates, has been engaged in a ten-year project on Langholm Moor in the Scottish Borders to find a way of managing grouse moors whilst resolving the age-old conflict with birds of prey.

No protected species are being controlled, and one tactic employed is the supply of carrion – dead animal matter – for birds of prey, so that they are less likely to depend on grouse for their diet.

Says the GWCT: “We abhor all cases of persecution of birds of prey, and regret the damage this causes to the image of people working on estates who are actually doing a lot of good for birds like waders.

“We hope that the Langholm Moor project will show that there does not need to be any conflict between wildlife conservation and game management.”

Ring Ouzels & Ospreys

This week we have been watching five Ring Ouzels. This is an iconic bird in the Yorkshire Dales which is notorious difficult to see. Ring Ouzels are very shy and will quickly disappear as soon as they become aware of your presence.

Cuckoo in egg pattern 'arms race'

By Emma Brennand
Earth News reporter

Imitation egg patterns allow cuckoo eggs to infiltrate unsuspecting nests.

Cuckoos' egg forgery skills are increasingly being put to the test, as host birds evolve better defences, say scientists.

These brood parasites, as they are called, are master deceivers - hiding their eggs in other species' nests.
To avoid detection, cuckoos have evolved to mimic colour and pattern of their favoured host birds' eggs.
But researchers have developed "bird's-eye view" models to find out how the hosts see the intruders' copycat eggs.
If host birds do not reject cuckoo eggs, the newly hatched cuckoo chick ejects other eggs from the nest by hoisting them onto its back and dumping them over the edge.

This study revealed details about the "evolutionary arms race" in which cuckoos are embroiled; as they evolve better mimicry, their hosts evolve the skills to spot these damaging intruders.
Mary Caswell Stoddard and Martin Stevens from the Department of Zoology at the University of Cambridge, UK, published their findings in the journal Evolution.
Previous egg pattern research has focused on assessing differences between colour and markings based on human visual inspection."But birds have better colour vision than humans do," Ms Stoddard told BBC News.

"Birds have four [colour-sensitive cells] known as cones in their retinas, while humans only have three."
"This additional cone in birds is sensitive to ultraviolet wavelengths [of light]. As a result, birds can see a wider range of colours than humans can."
The team used a technique called spectroscopy to measure the amount of light reflected from the different coloured egg shells.
They modelled these colour values to work out how the egg patterns appeared from a bird's perspective.

Avian invaders
Cuckoos have target hosts. For example, a cuckoo that lays eggs in a redstart nest lays a blue egg. To the human eye, this is identical to the redstart egg.

However, the cuckoo that targets a dunnock nest lays a white egg with brown speckling, visibly different from the dunnock's immaculately blue egg. Yet despite this obvious colour mismatch, dunnocks readily accept the foreign eggs, whereas redstarts are much more likely to eject the cuckoo's egg.

To investigate this optical conundrum, the team used their technique to study cuckoo and host bird eggs from 248 invaded nests held in the Natural History Museum in Tring, Hertfordshire.
They found that redstarts and their invading cuckoos' eggs had a higher degree of colour mimicry, so the cuckoo egg was a good copy.

The scientists think the cuckoos have been forced to evolve this high degree of mimicry because redstarts are better at identifying these alien eggs.
Even seen with this bird's-eye view, the cuckoos that targeted dunnocks' nests showed no colour overlap, so the forgeries were poor replicas.
The fact that the dunnock usually accepted these forgeries suggested that it lacked the defensive skills the redstart had evolved.

Exactly why many hosts accept such obviously alien eggs continues to baffle biologists.
Researchers think that naive hosts, like the dunnock, are still at early stages of the evolutionary arms race and, "they accept alien eggs, because they have not yet evolved defences against parasitism," explains Ms Stoddard.

"Another hypothesis is that tolerating cuckoo eggs may be the most stable strategy for some hosts."
So, for birds that do not often suffer cuckoo invasions, the overall "cost" of mistakenly ejecting their own eggs might be higher than the cost of tolerating the occasional parasite.

Rare white-tailed eagle spotted in Hampshire


An endangered bird of prey normally only seen in Britain in the far north west of Scotland has been spotted on a farm in Hampshire.

Bird-watching enthusiasts from across the country are flocking to Old Basing, near Basingstoke, to catch a glimpse of the rare white-tailed eagle.
It is thought that the giant apex predator, which has a 9ft wingspan, arrived from Scandinavia in search of a more abundant hunting ground.
Paul Outhwaite, an RSPB spokesman, said: “It is extremely unusual to see this bird so far south in Britain or indeed anywhere outside northern Scotland.
“It is the most spectacular bird to see in the air – they’re colloquially known as ‘flying barn doors’ because of their sheer size.”
He added it is likely that the eagle, which usually feeds on fish and other birds, crossed the North Sea to escape the bitter winter in Scandinavia.

Experts believe the bird may have settled in the area due to the diverse habitat, which also boasts several rare bird species, and other raptors including red kites.
Hamish Wardrop, a farmer where the eagle has taken up residence, said: “This shows that a working farm can provide an excellent habitat for rare birdlife.
“Sadly, the council has earmarked the area as a potential site for 9,000 new homes. It would be tragic to lose such a rich slice of countryside.
The white-tailed sea eagle, as the species is also sometimes referred to, was hunted to extinction in Britain in the 19th century.
Although re-introduced in Scotland through breeding programmes, it is still included on the RSPB’s Red list of UK birds because of the long-term threat to the population.

Bird watching gets sexy

by Katherine Hayes

Bird watching, twitching and birding are all pursuits that have not generally been associated with cupid’s arching arrow.

Similarly, if you’re a bird (the feathered kind) then it’s the time of year when the mind turns to courting and finding that all important nesting site.

Whilst the bad news is that birding watching pursuits aren’t getting any sexier, for the capital’s birds it’s a little different as thanks to 51% Studio and the Architecture Foundation, there are plenty of new places birds can raise their urban brood.
















It’s all thanks to 51% studio’s discovery that the standard hollow block used to build some of London’s most celebrated architecture is made from concrete and recycled wood shavings. Whilst this may seem unremarkable, to our winged companions, wood shavings really are the stuff of love because when used as a nest box lining, it’s proven to fledge more young than any other.

In answer to the plight of our native sparrows, wrens and other species that were once familiar sights on our island, now sadly and mysteriously, in decline, these ’love nests’ (groan) are being installed at various locations around London’s Bankside.

Intended as a permanent legacy for the London Festival of Architecture, the website to accompany the project launched, appropriately, on Valentine’s Day.

Even better is that if this news inspires you to take up the binoculars and follow our feathered friends, then you’ll be quite pleased to learn that you will earn the title of ’dude’. Now if that doesn’t make birding sexy, I don’t know what does.
