News and comment Compiled by Adrian Pitches Opinions expressed in this feature are not necessarily those of British Birds As this graphic image shows, birders in Malta face a level of threat unrecognisable to most birders in mainland Europe. Three cars, including that of John Borg from Heritage Malta, were destroyed in an arson attack as the war of words over spring hunting in Malta literally reached a flashpoint. European Court action is looming over the Maltese Government’s continued flouting of the EU Birds Directive since accession to the European Union in 2004. And spring hunting of Common Quail Coturnix coturnix and Turtle Dove Streptopelia turtur was a significant issue in the Maltese general election. Labour had pledged to put spring hunting on hold but it was John Borg Spring hunting fight turns ugly in Malta 117. The scene bird ringers in Malta returned to in late February… the incumbent Nationalist Party that was returned to power with a one-seat majority. An announcement on whether or not the Nationalist PM Lawrence Gonzi will permit spring hunting in 2008 is imminent. And birders’ car is attacked on North York Moors Volume 100 of BBi now available Another incident of criminal damage to a birder’s car has been recorded much closer to home. It’s far less devastating than the Maltese attack – but unpleasant and troubling nonetheless. Teesmouth Bird Club chairman Ted Parker takes up the story: ‘At Sleddale on Sunday 10th February, several of our members were parked in one car on the Commondale to Kildale road looking for raptors. Being a nice day, they left their car to walk up the road towards Commondale and, on returning a short while later, found a man in a green Land Rover interfering with their tyres. When the man saw them, he got into his vehicle and sped off down the road towards Kildale. It transpired that he had slashed all four tyres of the car. ‘Other birders who were present gave chase and the Land Rover turned left onto the Westerdale road, down to the ford at Hob Hole and up the steep bank on the other side. Unfortunately, due to icy conditions, the birders’ car couldn’t negotiate the bank and follow the man any further. The Land Rover was a hand-painted green, with an old-style number plate and a vertical exhaust pipe at the front near the bonnet. ‘I am assured that the birders’ car was parked well off the road and not causing any problem, so it can only be assumed that this criminal act was conducted against those who were known to be birders by someone who, for whatever reason, doesn’t like birdwatchers. ‘Incidents such as this against people who merely wish to enjoy the countryside are totally unacceptable and one can only assume the motives of the perpetrator and what other criminal acts he is carrying out in our countryside. It is to be hoped that the police will find and prosecute this criminal.’ Subscribers to our centenary DVDROM British Birds interactive (BBi) will be pleased to learn that the electronic version of Vol. 100 of British Birds is now available to download on the BirdGuides website.

The case was heard at Scarborough Magistrates Court on 8th February. In May 2007, following allegations of traps being set to catch raptors, North Yorkshire Police, supported by the RSPB and RSPCA, visited the Snilesworth Estate, owned by Mr Mark Osborne, of Banbury, Oxfordshire. James Benjamin Shuttlewood, of Hagg House, Snilesworth, Hawnby, is the head keeper of the Snilesworth Estate. A gamekeeper of 20 years’ experience, Shuttlewood pleaded guilty to five offences, relating to the setting of illegal traps by his subordinates. He was fined £250 for each offence. Charles Lambert Woof, of Sparrow Hall, Scugdale, Swainby, pleaded guilty to one offence of misusing a cage trap. He was fined £100. Eighteen-year-old David George Cook, of Ingleby House Farm, Ingleby, Arncliffe, pleaded guilty to two offences of setting cage traps. Cook, who was 17 at the time the offences were committed, was given a conditional discharge for 12 months. Additionally, the three convicted keepers have each been asked to pay £43 costs. Commenting on the verdict, Ian West, head of the RSPB’s investigations team, said: ‘The conviction of another three gamekeepers for attempting to kill birds of prey provides further evidence of the lack of tolerance some estates have towards these fantastic birds. The estate is part of a network of shooting estates managed by Osborne. Ian West added: ‘As a major manager of shooting estates, Mr Osborne has a real opportunity to show leadership and signal an end to the Victorian tradition of intolerance towards birds of prey.’ British Birds 101 • April 2008 • 220–223 Winter sport capers scare off Capers Expansion of winter sports in the Highlands could have a major impact on the vulnerable Capercaillie Tetrao urogallus population. A study of German birds has found that the species is significantly affected by disturbance from winter sports tourism. The researchers say a craze for winter snowshoe walking is having a particular impact on the Capercaillie because walkers are able to reach parts of open woodland that off-piste skiers typically don’t visit. In some areas, the birds have very few undisturbed refuges left. The Capercaillie is common in Scandinavia and Russia, but clings to survival in Scotland. It became extinct in Scotland in the 1770s, but was reintroduced to Perthshire in 1837. Researchers studied populations of the giant grouse in the Black Forest, in southern Germany. The team attached radio transmitters to 13 birds so that they could follow their movements. They also collected droppings from the tracked birds and from more than 50 other individuals. The team analysed these for breakdown products of a stress hormone. They found that the birds avoid areas most heavily used by winter sports enthusiasts. Furthermore, droppings deposited closest to these areas had higher levels of stress-hormone breakdown chemicals, indicating that they came from the most stressed birds. The team believes that this is an indication of problems for the birds, which may lead to difficulties in breeding. Dr Lukas Jenni of the Swiss Ornithological Institute in Sempach, who led the study, recommends that tourism development be halted in regions inhabited by the Capercaillie and more restrictions introduced to prevent tourists from straying away from marked trails. An RSPB spokesman said that the results tied in with its studies at Abernethy in the Cairngorms, the UK’s largest remnant of the ancient Caledonian pine forest and posed ‘questions about how we promote recreation and access in sensitive forests where there are Capercaillie.’ More ‘Spoonies’ discovered Some heartening news for fans of that charismatic wader, the Spoon-billed Sandpiper Eurynorhynchus pygmeus: sightings of 84 ‘Spoonies’ at two coastal wetland sites in Myanmar have cast new light on the winter distribution of this Endangered species, and confirmed that these wetlands are of international importance for their biodiversity. The known global population of Spoon-billed Sandpiper has plunged alarmingly in the last few years to only 200–300 pairs. ‘The number of breeding pairs in Chukotka, Siberia, fell by 50% between 2006 and 2007, and no birds have been seen this year at their traditional wintering sites in Bangladesh,’ says Evgeny Syroechkovskiy, Vice President of the Russian Bird Conservation Union (BirdLife in Russia). Analysis of satellite images, combined with the experience of previous surveys in India, Bangladesh and Thailand, and with historical records of the species in Myanmar, suggested that potentially suitable habitats existed in the southwestern state of Arakan (Rakhine) in the Bay of Bengal, and Martaban (Mottama) Bay near the Thai border. Thirty-five Spoon-billed Sandpipers were counted at one high-tide roost in Arakan, which had never been surveyed before, including one juvenile ringed on the breeding grounds in Chukotka last summer. The team at Martaban found a total of 48 Spoon-billed Sandpipers, scattered over the huge mudflats of the bay, but including a flock of 39 birds.

But there is a ray of sunshine in the Outer Hebrides, where a simple change in crofting practice has seen an upturn in fortunes for the ‘fat bird of the barley’. The Corn Bunting was once common as far north as Shetland, but suffered a decline of 86% in the UK between 1967 and 2003. The Scottish population of this red-listed species now comprises just 800 territorial males, concentrated mainly in the eastern lowlands from Moray to Fife, and with isolated populations in the Outer Hebrides and Inverness-shire. All of these populations are still falling, except in the Outer Hebrides, where numbers increased by over 20%, from 111 to 134 territorial males, between 2006 and 2007, 118. Corn Bunting Emberiza calandra. after many years of gradual decline. This is thought to be a response to a scheme introduced in 2004 (the ‘Uist and Barra Arable Stack Scheme’) which pays crofters to stack a part of their grain crop in the autumn. This provides a valuable winter food source for Corn Buntings, which is otherwise lost when the crop is stored in black plastic bales. Jamie Boyle, RSPB Uist Warden, said: ‘The changes in harvesting techniques in the Uists unfortunately removed a major winter food source for Corn Buntings. Farmers now generally harvest crops early, before they come to seed, and wrap them up in big plastic bags to store as silage over winter. By offering payments to crofters, we seem to have been able to help the Corn Bunting at the same time as preserving a traditional form of agriculture in the Uists.’ At the time of writing, David Beckham’s 100th appearance for England is still in the balance but another Beck’s has reappeared in spectacular fashion. Beck’s Petrel Pseudobulweria becki was known only from two records from the 1920s. Now it’s been rediscovered in the Pacific after a gap of 79 years. Writing in the Bulletin of the British Ornithologists’ Club (Bull. BOC 128: 3–16), Hadoram Shirihai has described how he tracked down this enigmatic tubenose on an expedition around the islands northeast of Papua New Guinea in July and August 2007. On his voyage around New Britain and New Ireland, Hadoram managed to photograph more than 30 of these elusive seabirds. Some of the petrels were fledged juveniles, suggesting recent breeding. A freshly dead young bird salvaged at sea becomes only the third specimen in existence. ‘This re-finding of Beck’s Petrel is exceptional news and congratulations to Hadoram Shirihai for his effort and energy in rediscovering this “lost” petrel,’ commented Dr Stuart Butchart, BirdLife’s Global Species Programme Co-ordinator. Hadoram first visited the area in 2003, where he observed ‘possible Beck’s Petrels’ – inspiring him to return four years later. Explaining this decision, he commented: ‘I was eager to know about these amazing petrels… and to understand better how we may conserve them.’ The petrel was first described by Rollo Beck, an ornithologist and collector of museum specimens, and was previously known from just two specimens he collected in 1928 and 1929 during an expedition to the region. Hopes were raised two years ago in Australia with the sighting of a possible Beck’s Petrel in the Coral Sea off Queensland, but this record was not accepted by the Birds Australia Rarities Committee. Confirming the existence of Beck’s Petrel was difficult because it is similar to Tahiti Petrel Godparents for Godwits Rare raptors are regular recipients of voluntary nestwatch schemes. But this spring the RSPB in northwest England is seeking godparents for nesting waders – Black-tailed Godwits Limosa limosa. Each year one or two pairs of Black-tailed Godwits nest on marshland on the Ribble estuary. Only around 60 pairs breed in the whole of the UK, and those on the Ribble are the only ones in northwest England. Their rarity makes them a target for egg thieves, however, and if the birds breed this year the RSPB and Fylde Bird Club will mount a 24-hour guard on the nest. The two organisations have launched an appeal for people to become ‘godwit guardians’, by volunteering to help with the nestwatch near Freckleton.

Until the breeding sites have been identified, the threats remain speculative but BirdLife has designated Beck’s Petrel as Critically Endangered. Corrections The authors of the paper ‘The use of stable-isotope ratios in ornithology’ (Brit. Birds 101: 112–130) wish to point out that when the mass spectrometer vapourises the sample and propels the ions into the magnetic field, the force deflects the ions to a degree that is dependent on the mass-to-charge ratio, so light ions (of course) get deflected more than heavier ones. We regret an unfortunate mistake in the original, where it is stated in Box 1 that ‘light hydrogen with be deflected less by the magnetic field than heavy hydrogen’.
