Why farms need dung beetles, why choughs need dung beetles, why we all need dung beetles

Dung beetles belong to the group of insects called the Scarabaeoidea, which include dung beetles, chafer and stag beetles. There are just over one hundred species in the UK, of which over half are dung beetles. The National Recording Scheme for Scarabaeiodea has existed for many years, and has mostly been a data collection point and identification support to the recording community. As part of the on-going Species Status Project by Natural England in collaboration with Buglife, a review of the scarce and threatened dung beetles and chafers is currently in progress (to be published next year). This project highlighted the lack of modern records for many rare species and areas of the UK that were severely under recorded. This prompted us, Darren Mann (Head of Life Collections at the Oxford University Museum of Natural History), Steve Lane, Ceri Watkins and myself (Sally-Ann Spence) to go out look for beetles in under-recorded areas and to re-survey sites where rare species were previously known. Together we set up the Dung beetle UK Mapping Project – affectionately abbreviated to DUMP and drawn attention to our project using the Twitter hashtags #dungathon and #dungisfun.

In addition to the fieldwork, we are examining museum collections to extract data for the historic distribution of species. We have put out a call to the beetle recording community, and data mined Irecord and Ispot. All of this data is building better distribution maps, informing habitat preferences and providing other ecological data for the UK dung beetle species. The end result will be a dataset of dung beetle information, including identification, distribution maps, ecology and species conservation status. This will be made available via The British Beetles website and will include an on-line recording system using Irecord.

Why we all need dung beetles

Dung beetles are considered key Ecosystem Service Providers within the livestock sector. They deliver many benefits to farmers including increased soil nutrients and general nutrient recycling. They improve the soil structure by increasing aeration and drainage which in turn increases rain water filtration through the soil which also leads to a reduced run-off of rainfall – research is also looking at their pasture reseeding capabilities, abilities to reduce anaerobic processes and decrease methane formation. We know the process of pasture reseeding can have detrimental effects on soil erosion too.

They reduce pest flies, gastrointestinal parasites and pasture fouling by carrying fly egg and larval eating mites with them as well as consuming the dung the maggots live in themselves. Research is on-going into their part in nitrogen and carbon recycling but we know they are incredibly important in keeping pastures green and healthy for livestock especially in the absence of non-organic artificial fertilisers. Our results mapping the dung beetle species in the UK (although the project is in its youth), are already showing an alarming trend in species rarity and even extinction. The three main reasons behind this are considered to be the use of anthelmintics (especially in wormers), soil disturbance and the disappearance of livestock from historic pastures due to a change in farming practices.

We take the opportunity of our survey visits to make farmers/livestock keepers aware of their dung beetles, the latest research, their economic benefits and how they might implement simple workable measures to ensure a healthy dung beetle population. We have received a fantastically positive response from all we have spoken to. Farmers are keen to preserve their dung beetles and we intend to gather more data about species and their population frequencies to enable more research into these incredibly important beetles.

We are at present unfunded (please contact if interested in helping to fund this vital project) so as individuals we are surveying the whole of the UK in our spare time, on family holidays or around other work. It is a huge labour of dung beetle devotion. We are obsessives and dung is a big part of our lives. The project is vast. Different species live in or under different dung in different stages of decomposition on different soils at different altitudes at different times of the year. Dung quality is important too. We have become connoisseurs of fine dung. Not adverse to feeling the texture or giving it a good sniff (you can tell a lot about an animals health by its dung), we will examine it and the soil underneath meticulously for beetles. All data is noted on the spot – the date, GPS location, soil type, weather conditions, temperature, elevation, dung type, pasture quality and time spent in that locality surveying.

Dung beetles in Jersey

Minotaur beetle burrow freshly dug near Devils Hole and the beetle was actively taking sheep dung into it.On a recent trip to Jersey helping a colleague working on the Ice Age Project, I took the opportunity to contact the Roger Long of the Société Jersiaise to trace some historical specimens in their collection that I had become aware of through my research. Never to miss a chance I also managed to survey a few isolated locations and one of which was the area around Devils Hole. It was just awesome to encounter large areas of Minotaur beetle Typhaeus typhoeus burrows. These dung beetles like sheep and rabbit dung on light soils with short turf. The population in this area was extremely good and as it became dark the air hummed with them flying in on sheep dung. They fill their burrows with the dung for their larvae to feed on. The smaller Aphodius sphacelatus and Aphodius prodromus were also represented in good numbers. These Autumn emergence species feed in the dung itself. Excitingly I also found Aphodius affinis in this area. Another small dung beetle that feeds within the dung but is not found in the UK and is considered rare in France. It was also a first record for Jersey.

These dung beetles and their larvae are a vital part of food webs supporting many insectivorous birds and omnivorous mammals. The Minotaur beetles in particular are a important food resource for the choughs (see photo here)  and it was excellent to see the sheep maintaining the right habitat for these beetles by their grazing behaviour and the dung they produced.

We hope to be back in Jersey in May 2016 to complete a whole Island dung beetle survey. This will provide a species list and population density records crucial for further research into Jersey’s precious ecosystems.

They might not seem like it at first glance, but the sheep at Sorel are part of a special task force deployed in Jersey to help protect and serve the Island’s biodiversity. And now to boot they have celebrity status! Having featured on BBC’s Countryfile back in summer and subsequently attracting tourists to the north coast they have once again hit the headlines with ITV Report.

Working hard on our coastline since 2009

Having been established back in 2009 with just 20 breeding ewes and two rams, Jersey’s conservation grazing flock of Manx loaghtan sheep is now almost 200 strong. The Manx loaghtan, a hardy rare breed thought to be the closest living relative of the now extinct Jersey sheep, originate from the Isle of Man. Since their introduction, the flock have been invaluable in addressing the widespread ecological degradation that has taken place along Jersey’s north coast.

Historically, the coastal headlands and slopes on Jersey’s north coast were grazed; however changes in Jersey’s economy during the early 20th century led to the cessation of traditional mixed farming practices on marginal land. When active management ceased, the semi-natural open grassland and heathland habitats characteristic of traditionally farmed marginal areas began to be invaded by bracken and scrub. The invasion of bracken in particular, which now blankets vast swathes of land along the north coast of the Island, has sadly led to a widespread decline in biodiversity.

Reinstating active management is the key to restoring species-rich semi-natural maritime grassland and heathland habitats. The Manx loaghtan flock contribute enormously in this respect. Through the action of trampling, the sheep help to reduce the cover of bracken, while grazing controls the growth of competitive plant species, prevents scrub invasion, and facilitates the development of diverse plant communities with varied sward structures. In addition, patches of bare ground and animal dung resulting from sheep grazing provide important resources for invertebrates.

Sheep, choughs and other birds

The Manx loaghtan grazing area at Le Don Paton provides ideal habitat for the choughs. These iconic birds forage for invertebrate prey in areas of short turf and dung produced by the grazing sheep, and also use wool in nest building. In addition to benefiting Jersey’s resident wildlife, the short grassy areas maintained by grazing also provide feeding opportunities for migratory bird species of conservation concern, such as meadow pipit, wheatear and ring ouzel. P1070125

The increase in the size of the flock is fantastic news as it will allow this highly effective and sustainable management technique to be more widely applied, facilitating the restoration of Jersey’s coastal headland habitat for the benefit of our native wildlife.

Sheep and people

The flock have proven to be extremely popular with both visitors and local residents alike, to the extent that they are now something of a visitor attraction. An additional benefit of the increase in flock size is the increased production of high quality meat for the local market, as well as wool for craft knitting.

Winter is coming and …..and so are the birds!

Note details of forthcoming Birds On The Edge walks below.

It’s that time of the year again, when suddenly it seems the summer went by too fast and the cold and the rain arrived too soon. But here at Birds On The Edge we like to be prepared, which is why we started planning this winter’s bird crops back in December 2014.

Once again Birds On The Edge and a dozen of our farmer friends got together to discuss where the so-called ‘winter bird crops’ would be planted, with sites, crops and timing with everybody’s approval. The seed was provided by Birds On The Edge and most of the fields were planted between May and July, slowly growing to form the mixture of flowers and other plants that have started to become a familiar landmark in Jersey.

We hope that you have recognized our crops as you drive by or go for a stroll; those large sunflowers and purple phacelia are not easy to miss, but if you look closely you’ll also notice mustard, barley, millet and quinoa amongst others – this mixture will feed the widest range of birds with different beak shapes and sizes. When in full bloom the crops indeed look spectacular, and feed hundreds of bees, butterflies and beetles, but it is now, when they are dried up, looking dull and brown, that they are most appetizing for the birds, for now the seeds have matured and are ready to be eaten. These crops are particularly aimed to help farmland birds make it through the winter, which is the time of the year in which they are most vulnerable. It has been shown that the decline of birds associated with farmland seen across Europe and in the UK is caused by the lack of food available in modern farming habitats, with less stubble fields, weeds and spilt cereals. These crops help birds like linnet, meadow pipit, skylark, reed bunting, cirl bunting, brambling, stonechat, and even chaffinch and greenfinch, to survive the coldest months until the spring, when insects and other invertebrates become more abundant.

The winter bird crops have also become more prominent as the scheme has grown from 14 fields at five sites in 2013 to this year’s 47 fields at 12 different sites across the Island. Some of the fields are ‘out in the sticks’ and quite difficult to find, whilst others are near footpaths or areas with public access; in those we have placed signs encouraging walkers to enjoy the birds without disturbing them from feeding.

Winter is coming field sign. Birds On The Edge

The success of these crops has also increased each year, with 74% more farmland birds per hectare planted out and as much as a 414% increase at the best performing site. New species are often found on the crops, with serin, little bunting and Dartford warbler seen at the crops last winter, and Cetti’s warbler added to our list at one of the sites already this autumn.

We have been lucky to receive generous donations and grants to plants the crops every year. The birds are enjoying this winter’s crops thanks to a private donation from a local ornithologist, whilst the monitoring work will be carried out with grants from the Co-Operative Society Eco-Fund and the Howard Davis Farm Trust. And, we already have good news for next year’s crops, as Jersey’s Action For Wildlife have kindly offered to cover half of next year’s expenses.

If you would like to see the crops and learn a bit more about them come join us this month at one of our Birds On The Edge walks:

Thanks to the skill and hard work of the guys on the Back to Work scheme and Ecoscape, the sheep now have access to extra grazing land at Sorel.

A fence has been erected around the field adjacent to the chough release-aviary allowing for the shepherd to improve the management of his flock. It is a relatively small area, but it will make a huge difference.

P1620318

P1620359 P1620334Once the fence was up and tools cleared away, the shepherds then had the seemingly mammoth task of herding the sheep from the cliffs and picking out which sheep would go in the new site. Luckily for them Mist the sheep dog, made the job a lot easier.

Up until the beginning of the 20th Century, the coastal headlands were an important part of the rural economy. Cattle, ponies and sheep would have grazed upon these areas and gorse and bracken would have been collected for fuel and bedding respectively. The disappearance of such practices allowed bracken and scrub to encroach, in turn leading to the disappearance of many coastal and heathland species. The red-billed chough is a prime example of such a species relying on the sheep to improve habitat as well as providing their wool for nest building.

P1630835 P1630837The Back to Work scheme, set up by the Social Security Department and Department of the Environment, helps unemployed people in Jersey to gain skills and experience to attain permanent employment while carrying out dedicated projects enhancing Jersey’s biodiversity.

Ecoscape, a local contractor with a wealth of environmental experience, provide guidance and training to participants on the scheme. Its hard work at times, but the skills acquired and sense of achievement with the end result can be very rewarding.

Monitoring schemes in Jersey and the BOTE Breeding Bird Survey

DSC_0036By Cris Sellarés

If a conservation initiative like Birds On The Edge aims to restore bird populations and stop them from further declines, it is important that we keep our eyes on the target. Even when you are busy restoring habitats, planting winter bird crops, clearing bracken and introducing grazing flocks, unless you monitor how the birds are actually doing, you can’t just assume that things will work out, just because they work well elsewhere.

In short, doing the conservation work itself is only half of the job. Any project needs to put in place systems to measure its progress, not only to find out whether techniques actually work but also when to stop, evaluate and adjust. Real-time feedback allows us to adapt the techniques that we use, saving a great amount of work, time and money.

Thankfully some local initiatives have been monitoring birds in Jersey for quite a while. The Ornithology Section of the Société Jersiaise collects bird records all year round and publishes an annual bird report summarizing each species’ year. During spring, our local representative of the BTO co-ordinates a team of volunteers that survey randomly selected squares twice in a 6-week period and record all breeding birds and their activity. The BTO then publishes a nationwide analysis and report on general trends based on everybody’s input. On top of that, every year the BTO organizes a nationwide census for a different species, in which Jersey’s ornithologists also participate. Last year it was the peregrine falcon, this year it’s the turn of the house martin.

Goldfinch. Photo by Mick DrydenThe Farmland Monitoring Scheme set up in 2005 and co-ordinated by Dr Glyn Young at Durrell, collects data from 22 transects walked by volunteers every fortnight throughout the year. So far it has collected date from over 3,200 individual site counts as it celebrates the first 10 years of work (watch out on the website for a full report). Other annual surveys organized locally include the Jersey Garden Bird Watch, organised by Action for Wildlife and Birds On The Edge, and various wader, geese and raptor counts which help create a picture of long-term trends of the most well-known species.

In 2013, Birds On The Edge started its own ‘breeding birds survey’, partly to complement these schemes, and partly to fill a gap which was relevant to the project, that is to focus survey efforts on Jersey’s most threatened coastal and farmland birds. This survey pays special attention to endangered species found in the areas of work (north-west and western coasts to start with), such as the stonechat, skylark, lapwing and turtle dove, plus Island-wide species whose status is uncertain such as the kestrel and the starling. The survey also includes other species whose populations seem stable, such as the raven or the peregrine falcon, yet are considered highly vulnerable due to only a small number of breeding pairs.

We are pleased to publish now the report of the 2014 survey (download a copy here). Over the two years of the survey to date, we have found high enough numbers of certain species such as the meadow pipit, linnet, Dartford warbler and common whitethroat, for example, to make it difficult to monitor each breeding pair. This suggests that any changes in the population trends will be, and already are, reliably picked up by long-term monitoring schemes such as the Farmland Monitoring Scheme.

TCirl bunting (8). Photo by Mick Drydenhe majority of resources were placed instead in monitoring the breeding success of our smaller bird populations. Over the course of two years we have seen an increase in the number of stonechat pairs, going from two to six and we have seen the cirl buntings, which returned in 2011, increase to two pairs. The breeding success of one of our most threatened birds, however, the turtle dove, proved difficult to confirm in 2014, although a single pair was seen nest-building. Skylarks seemed also to follow the negative trend of the last few years while lapwings remain at very low numbers, and are not able to reverse their decline of the last few years. In contrast, other small populations, such as that of the raven and the peregrine, do seem more stable at 3-5 breeding pairs.

The 2014 report also recommends a few new species to be included in this year’s (2015) survey, like the sedge warbler and the sand martin, and reminds us to keep a close eye on species that are suffering declines in the UK, such as the kestrel and the common starling, as their present trend in Jersey is anything but clear.

Results from one year to the next have to be taken with much caution and interpreted in the wider context of long-term trends and habitat changes. Having said that, it is important to continue monitoring the small populations that we have in Jersey as they are very vulnerable to rapid extinction events, and any acute dip in the population or any new threat (a disease, a new predator, changes in habitat) will be detected early and might allow us to take action before its too late.

‘Operation Skylark’. Conservation Herd project at Port Soif, Guernsey

The Conservation Herd at Port Soif, Guernsey. Photo by Consrvation HerdBy Julia Henney and Pat Costen

La Societe GuernsiaiseLa Société Guernesiaise is to use its herd of six Guernsey steers to try to attract the skylark back to the Island by reintroducing grazing to the Port Soif Common area this summer. Many Islanders will remember the wonderful sight and sound of the skylarks that were once widespread in Guernsey, but sadly, apart from the odd visitor, no more. The area around Port Soif was well-known for these lovely ground-nesting birds, but none has bred there for about eight years.

La Societe Conservation HerdThe Conservation Herd moved to the area last weekend and will be grazing there for roughly six weeks to try to re-establish the habitat that attracted the birds to breed there.

Physical disturbance of the ground by trampling creates small bare patches of earth which disturb the seed bank and helps the germination of wildflowers. This has the potential to allow plants which may once have been considered lost from a site to re-establish or spread. These bare patches can also be important for ants and nesting solitary bees and wasps – and, hopefully, skylarks.

DSC_2889

The birds won’t have far to travel. Jersey still has a population and conservationists there are very supportive of our efforts to bring some back here.

The land is managed by Guernsey’s Environment Department and since traditional grazing ended, the area has been tractor-mown each year. Tractor mowing is efficient but leaves the cut vegetation on the ground and a ‘thatch’ of dead grass builds up, the thatch smothers finer grasses and plants, encouraging coarser plants such as common hogweed and brambles to thrive. Reintroducing traditional grazing will increase the range of plants found here and an improved habitat will develop for insects and small mammals. Grazing these areas of land will also allow the grassland to retain small tussocks of grass which are ideal nesting sites for skylarks.

IMGP2150Julia Henney, the Conservation Herd’s manager, said, “Birds such as skylarks and cuckoo were commonly seen in Guernsey until relatively recently. Traditional grazing around the coast has almost stopped and by reintroducing the Conservation Herd to selected sites we hope to recreate more favourable conditions that will encourage them to return here and, over time, to breed regularly on the Island. The Conservation Herd will be ideal to give ‘Operation Skylark’ the best possible start and it’s an exciting project for everyone involved.”

The Conservation Herd will be grazing within electric fencing for several weeks around Port Soif and will be checked daily by the team which cares for them. La Société and the Environment Department would welcome assistance from regular dog walkers and people who walk or exercise around Port Soif. ‘Watchers’ are sought to keep an eye on the cattle when they’re passing and report any problems or concerns to the Conservation Herd team.

Temporary signs are placed around the site to explain the project and give information on who to contact in the event of an emergency.

Anyone who would like more information on the Conservation Herd is welcome to contact conservationherd@societe.org.gg and follow the project on Facebook. Visit the online map here to track where they are grazing.

Restoring heather on Jersey’s coastline

Bell heather (2). Photo by Richard PerchardBy Sally Dalman

Are there many more beautiful sights in mid to late summer than that of a hillside covered in flowering heather? Against the backdrop of a blue sky and glorious sunshine, a sea of purples, pinks, and occasional whites, shimmering in the heat, there can be few more perfect sights. The hum of insect activity too can be heard, almost felt, from a distance amid the call of foraging birds.

Heather, whether it be Calluna vulgaris (ling) or Erica cinerea (bell W Gorse and bell heather (2). Photo by Richard Perchardheather), has long played a part in the landscape of Jersey, predominantly of the northern, rockier coastlines, but it can occur in any open landscape, wet and dry. In Jèrriais it is called d’la bruëthe, and has been used as many things through the ages: firelighters; bedding for farmers and their livestock; an orange dye (from the flowers); knife handles (from the roots), and, my personal favourite, it has been used to make beer.

It is also a favourite amongst much of our wildlife. Bees adore it, heather honey is a delicacy; some butterflies rely on it as a food source for their caterpillars; some birds, such as the choughs, like to line their nests with the newer, softer, shoots in spring; grazing livestock and rabbits like to eat those same soft, new shoots.

Heathers are a staple of the heathland flora, much preferring the acidic soils that most plants would struggle in. They flourish in areas where trees have been removed and the grazing of livestock has prevented their regrowth.

IMG_3650One component of the restoration project at Don Paton, Sorel Point, Mourier Valley and Devil’s Hole is the increase of heather in the existing heathland. The overall site had lacked any management for many years, before it was given to The National Trust for Jersey; the soil is too poor for arable farming to be successful, and the area had become overgrown with bracken, gorse, bramble and thick grasses. All of these other plants, of course, play their part in the habitat, but, left to their own devices, they will dominate and swamp any smaller more wildlife-friendly species. The National Trust rangers have worked hard to bring these other plants under control, and encourage those such as heather to gain a foothold.

Once areas had been cleared and more open spaces were created, with grasses growing, ably controlled, munched and fertilised, by the Manx loaghtan sheep, we could pinpoint areas where heather could be re-established.

Seed was collected from Les Landes by the States of Jersey rangers, as there is an abundance of well-established heather there. Les Landes is what we hope Don Paton will look like in a few years’ time, minus the castle and racecourse. After an application of sulphur had been applied to acidify the soils, the seed was scattered at Don Paton.

5Once the heather had started to grow, we realised just how popular it was as a food source for sheep and rabbits alike, and decided that we needed to protect it before it was lost again. When it is well established, gentle nibbling will not be too much of a problem, in fact it will be of benefit, but until that time, a sheep and rabbit-proof shield was required.

A post and wire fence was put up one winter, on a cold, wet, wild grey day (are there any other type of day in a Jersey winter?!), much to the amusement of the sheep, who watched us struggling to bury the wire in the rocky soil. They then thought it was hilarious to jump over the wire just as we packed up for the day. We were not amused.

A second, taller layer of wire was put up, in an attempt to remedy the sheep jumping. They they decided to tangle their horns in it instead, which caused holes to appear. Rabbit sized holes.

IMG_3648

A third attempt at protecting the heather, using stronger, taller wire (put up on a much sunnier day!) and at two much smaller sites than the first, has now been put up and, so far, seems to be keeping the animals out. We will be monitoring the areas regularly to ensure that the heather is not being eaten by the woolly jumpers or their bunny mates, at least until it is really well-established (or there is enough for the staff to start making beer!).

New research provides farmers with techniques to help turtle dove recovery

From RSPB

A new research study, conducted on six farms across East Anglia, has recommended a new agri-environment management option that could help in the recovery of UK turtle dove populations.

The study, carried out by the RSPB, found that cultivating grown seed with a mix of plant species in the autumn creates a habitat rich in seed that is easily accessible – ideal for turtle doves, which feed on seeds present on, or close to, the ground. The authors also suggest that light cultivation or cutting during spring would better prevent the plots from becoming too overgrown and, therefore, unsuitable for turtle doves.

UK turtle dove populations have fallen 88% since 1995, with one cause for this decline thought to be the lack of seed from arable plants, which historically formed the bulk of turtle dove diet during the breeding season, resulting in a much shorter breeding season with fewer nesting attempts.

This latest research into the management of bespoke seed mixes to provide food for turtle doves, (published in the Journal for Nature Conservation), is under consideration as a part of a modified version of the nectar flower mix option under the UK’s Countryside Stewardship Scheme and could be pivotal in providing food for turtle doves on farmland across the UK.

Patrick Barker, an arable farmer in Westhorpe, Suffolk, who took part in the study, said: “It’s been great to be involved in this research and to find out how we can give turtle doves a hand. What was particularly striking was that the areas they prefer don’t look as you’d expect. For example, we learned that bare patches on the ground amongst the vegetation give them space to land and move around.

“I hope that our work here will encourage other farmers to do the same, and that this will help turtle doves return to the countryside.”

This new management option is part of a wider ‘turtle dove package’, deployed within the Higher Level Stewardship scheme agreements on farms supporting turtle doves (or with turtle doves nearby), which seeks to provide foraging habitat in proximity to nesting turtle doves. The other options in this package include cultivated margins, fallows that promote seeding plants, and scrub and hedgerow management for nesting. The options a farmer selects will depend on local land characteristics and farming practices.

Tony Morris, Senior Conservation Scientist, RSPB Centre for Conservation Science said: “This research helps our understanding of how to provide food for turtle doves on farmland where the original sources of seed food have long since vanished but without unduly disrupting modern agriculture.

“Agri-environment schemes offer the best and perhaps last hope for this iconic species. We’re hopeful that, together with farmers and our partners in Operation Turtle Dove; we can reverse the decline of this bird and secure its long-term future in Britain.”

Jenny Dunn, RSPB Conservation Scientist, said: “The results of this research show that it is possible to create a ‘farmed’ habitat structure similar to that used by turtle doves historically – an area with a patchy structure containing both seed-rich plants and bare ground to allow turtle doves to access the seed.

Operation Hungry Gap – Jersey birds require desperate measures in desperate times

Linnet 3. Photo by Mick DrydenBy Cris Sellarés

Feeling cold? A bit hungry? Then you can probably empathise with the thousands of small birds out there struggling to survive the winter. You probably put some food too in your garden to help them, and it’s a good thing you did, for at a time when their calorie requirements increase in order to keep warm, it is also a time when there is less food available in the form of insects, seeds and fruits.

So, that’s good for your robins, blackbirds, blue tits and the sparrows (the last of which unfortunately are on the Jersey Red List and need all the help they can get). But, what about the other birds that won’t come to your garden, the ones traditionally associated with farmland?

Farmland birds such as the skylark, linnet and meadow pipit are suffering amongst the steepest declines of all birds across Europe, and their continuing survival is in jeopardy due to lack of food in the agricultural land they inhabit. In the past, spilt grain from less effective machinery, stubble fields left until the spring and land rotation would have kept them going, but these features are not so common in modern farming. Even without their traditional food sources, these birds won’t, however, unfortunately, be venturing into a garden to take advantage of your generosity.

In order to help these birds survive the winter, conservationists work with farmers to plant winter bird crops, and aim to provide the birds with seeds and cereals from November until March-April, when invertebrates and other natural sources of food start to re-appear (read more here and here). But even then, a bad combination of a long winter and a cold spring might leave a ‘hungry gap’, when birds struggle to find food anywhere.

In Jersey, this ‘hungry gap’ really lives up to its dreadful name and occurs as early as February, as even the most co-operative, wildlife-loving farmer that has grown winter bird crops, needs to plough his fields in the New Year to plant potatoes. This means that all the resources for the birds disappear suddenly and at the worst of times – about now. Its around now too that many other fields around the Island disappear under polythene offering even less hope in these fields for birds to find much-needed food.

La Coupe 7

So, how do you feed the birds out in the farmland? The solution is to feed them yourself, by hand, like you would do in your garden but on a much larger scale. This involves pouring big quantities of food at a designated site, at regular intervals throughout the winter. The type of food we use is typically a high-energy, husk-free mixture of seeds and grains in quantities varying between 20-60kg, put down once or twice a week, usually by a dry track next to a suitable hedge.

Birds On The Edge has been pioneering farmland feeding stations in the Island for the last two years and learning how to best manage them. Last year we implemented a feeding station at the conservation area of Sorel, and this year we have tried them at another three sites with positive results.

These feeding stations are located at existing conservation sites with winter crops, so that the birds don’t have to travel far to find the new food when the fields are ploughed. We start feeding in early January before ploughing so that birds get used to feeding from the site, and will put out food then until mid to late-April. We move the spot where the food is put down regularly, to prevent build up of grain that may attract pests. However, so far, all the food has disappeared within a couple of days.

P1100971

Farmland feeding stations have been tried and tested in England with positive results, and farmers get subsidies from Natural England to manage stations on their land. Here the Jersey Ecology Fund sponsored our very own ‘Operation Hungry Gap’ in 2014, and a private donor recently funded it for 2015. The other difference between here and England is that, whilst farmers usually put down grain from the back of their pick-ups or tractors, here we do it by hand and shoulder!

This might seem like a last-resort solution, but as farmland birds continue to decline across Europe and the Channel Islands, any measure that can help them make it through the winter could mean the difference between starving to death or surviving to see another spring full of possibilities.

Evidence of the need for a network of conservation fields

OLYMPUS DIGITAL CAMERABy Cris Sellarés

Two fields with winter bird crops planted out by Steven Baudains from J&S Growers near Les Landes, are, at the end of February, still filling up with birds that are probably now coming from other conservation sites on the Island, where the fields have already been ploughed. Since January the numbers of birds in the Les Landes fields have increased from average flock counts of around 100 birds to 400-600 birds. Most of the birds are chaffinches, with many linnets and reed buntings, goldfinches, greenfinches, and even the odd brambling. There are also lots of meadow pipits and stock doves, and raptors such as sparrowhawks, marsh harriers and even a common buzzard, an uncommon sight in the north-west, keeping an eye on them.

OLYMPUS DIGITAL CAMERAAnd just to confirm our suspicion that the birds are flocking in from other areas in Jersey no longer suitable, we ‘re-trapped’ a reed bunting caught first in the reedbeds at St Ouen’s Pond, where the buntings roost up for the night. This male bunting was re-trapped earlier this winter in conservation fields with bird-crops immediately behind the Pond, where good numbers of reed buntings have been counted this winter.

The most interesting bit is that, as those fields by the pond were ploughed during the first week of February, this bird and probably others have found their way to the fields at Les Landes, which is where it was re-trapped again on the 15th of February.

So much information carried by such a tiny thing! A great example too of the valuable data that can be gathered through ringing birds like this bunting. The bunting further shows the importance of having a network of conservation fields that can support the birds in this ‘hungry gap’ when many of the fields that they have needed to survive begin to get ploughed up.

Thanks again to the many farmers involved in this project for planting out all those fields. Without this effort birds like this reed bunting and the brambling would have gone hungry this winter.
