The choughs continued their travels around the Island this October with reports from Corbière, Noirmont and Wolf’s Lair.

There have been several reports from La Pulente, the south end of St Ouen’s Bay. However, this may be a case of misidentification. This end of the bay often attracts large numbers of crows due to the rich pickings available at low tide. In amongst those are another corvid relative, the jackdaw. See our guide to corvid identification here

Jackdaws have a distinctly different call to crows. They are not as prolific in Jersey as they are in the UK. Understandably, if you are not used to hearing the calls of jackdaws and choughs together you could easily misidentify the two species. Of course there is one obvious way of telling the difference; one has a red bill, the other doesn’t. Not easy to spot when driving – most of the reports came from birders in cars.

The difficult thing with all this is that birds can travel around the coast of Jersey much faster than humans. The birders out recording autumn migration numbers will attest to that. It is quite feasible that choughs were at Pulente, but nipped round the corner to Corbière before I had chance to follow-up the report.

End of British Summer Time…and the choughs’ travel plans?

When the clocks changed at the end of October so too did the attendance record at the aviary. We are now seeing more choughs at the supplemental feed. Forty-one being the highest on the eve of the clocks going back. That included Earl and Xaviour who have been living out at Plémont all year.

The increase in numbers is likely due to the cold snap and the reduction in wild food resources. Leatherjackets, a chough favourite, emerged as cranefly and spread their own wings removing themselves from the menu. The choughs reliance on the free food at the aviary will likely increase as we go into winter.

The choughs appear to be spending more time foraging around Devil’s Hole and Mourier Valley. At least when the whistle blows for food at 3pm, the majority of the choughs fly in from that direction. They could be fooling us. Probably all are at La Pulente until 2.50pm!

Replacing lost rings

The return of certain choughs to the supplemental feed has made it easier to see who has lost which rings. A catch-up of birds on 28th October attempted to correct this. It took a while to trap the birds in the aviary; the hatches had seized up again despite a check the day before.

It was also a lot harder now there are so many. We managed to lock in about two-thirds of the group and went about the process of hand-netting individuals to check rings.

There are several birds we knew needed rings such as Green who had lost all but his original metal ring. Then there were others like Mauve who, on closer inspection, had broken rings creating sharp, hazardous, edges.

All the birds we caught in the nets were weighed and checked over prior to release. There were twelve who got locked in the aviary that we didn’t need.

In amongst this last group was Xaviour who has been missing her orange rings since the start of summer. Unfortunately, she evaded capture. Clearly living out at Plémont has improved her flying skills in close quarters. Since we had already spent an hour catching and processing everyone we called it a day to avoid excessive stress on the group.

Five others still require ring replacements. Weather permitting; we can do that in November.

Feeding stations

Work on the new and improved magpie-proof feeders continues. A quick trip home to see family turned into a research and development trip for the choughs. B&M Bargains, Hobbycraft, Aldi, Lidl….ah the joys of mainland shopping…all threw up some new ideas.

The latest and most successful is a rather unusual choice – flower urns. With slight modification to the container depth, they make the perfect magpie-proof feeder. At the cost of £5.99 for two, salvaged wood and paint (hence the colour choice), they are relatively cheap and easy to make.

To end on a non-bird related note…

At the start of October, the waters around Sorel were graced with the presence of bottle-nosed dolphins. Clearly visible from the cliffpath, the small pod followed alongside a Jersey Seafaris rib as passengers toured the north coast. I tried to capture an image of both choughs and dolphins, but, let’s face it, with my long lens focused on the dolphins; the choughs never stood a chance.

Human-driven mass extinction is imminent

From BirdGuides and WWF

The World Wide Fund for Nature (WWF)’s latest Living Planet Report finds that humanity has wiped out 60% of animal populations since 1970. Policy makers are urged to set revised targets for sustainable development in the report, which documents a mass loss of wildlife and pending ecological meltdown, explaining that the Earth is losing biodiversity at a rate seen only during mass extinctions.

Fifty nine scientists from across the globe were involved with the compilation of the report, which finds that the huge and constantly growing consumption of food and resources by humans is the lead threat to the web of life – billions of years in the making – on which the global population depends for clean water and air.

Mike Barrett, Executive Director of Science and Conservation at WWF, commented: “We are sleepwalking towards the edge of a cliff.

“If there was a 60% decline in the human population, that would be equivalent to emptying North America, South America, Africa, Europe, China and Oceania. That is the scale of what we have done. This is far more than just being about losing the wonders of nature, desperately sad though that is. This is actually now jeopardising the future of people. Nature is not a ‘nice to have’ – it is our life-support system.”

Only a quarter of the world’s land area is now exempt from the impact of human activity, according to the report (and that’s without global climate change), and this is forecast to fall to just a tenth by 2050. Ever-rising food production and an increased demand for energy, land and water are the main drivers behind this obliteration of land and the life it holds. Many scientists believe a sixth mass extinction has begun on Earth, and is the first to be caused be a single species.

The report uses data on 16,704 populations of mammals, birds, fish, reptiles and amphibians, representing more than 4,000 species, to track the decline of wildlife. It found that South and Central America suffered the most dramatic decline in vertebrate populations – an 89% loss in populations compared with 1970. Marine freshwater species are particularly at risk, and plastic pollution has been detected in the deepest parts of the world’s oceans, including the bottom of the Mariana Trench in the Pacific.

Marco Lambertini, director general of WWF International, called for immediate change, saying: “We can no longer ignore the impact of current unsustainable production models and wasteful lifestyles”, with Barrett adding: “We need a new global deal for nature and people and we have this narrow window of less than two years to get it. This really is the last chance. We have to get it right this time.”

The Living Planet Report documents the state of the planet—including biodiversity, ecosystems, and demand on natural resources—and what it means for humans and wildlife. Published by WWF every two years, the report brings together a variety of research to provide a comprehensive view of the health of the Earth. Download the latest report here

November volunteer activity

Sunday 4th November 2018 – Grouville Marsh (Les Maltieres), Grouville – 10:30-13.00

From Jersey Conservation Volunteers

Please note that November’s task is a week earlier than normal to avoid clashing with Remembrance Sunday.

The details Join the National Trust for Jersey’s rangers at Grouville Marsh (Les Maltieres) for a morning of reedbed management and an opportunity to take a close look at the Trust’s recent wetland restoration project.

If you have any questions, or if you wish to be added to the Jersey Conservation Volunteers email list, please contact either Julia Meldrum (tel: 441600; j.meldrum@gov.je) or Jon Parkes (tel: 483193; jon.parkes@nationaltrust.je).

The site Meet at Long Beach carpark on Gorey coast road.

Jersey Phone Book map 11, square KK16. Google maps here. It’s a short walk over the road and through the back of the reedbed.

Parking There is parking at Long Beach carpark.

The task This task will involve cutting, clearing and burning reeds as well as some willow coppicing. Each year the Trust endeavours to cut and clear a section of the reedbed. This encourages greater floral diversity and creates a differing age structure within the reedbed. Removing or burning the cut reeds helps prevent the build-up of dead plant matter which can lead to the reedbed drying out. We will also be cutting some willow in order to prevent scrub encroachment.

Meet at 10.20 promptly for a 10.30 start. We will be finished work by 12.30 for well-earned refreshments.

Tools needed All tools will be provided.

Clothing needed Please dress for the weather, we go ahead whatever Nature throws at us. We can supply a pair of gardening gloves if you don’t have them.

Children All are welcome, young or old although we do ask that volunteers under 16 years of age are accompanied by an adult.

Refreshments The famous Kim’s Kafe will open to provide refreshments when work finishes at about 12.30.

Chough report: September 2018

By Liz Corry

Time for a holiday

With the breeding season behind them for another year the choughs decided it was time for some well-earned R&R. In the video below it is obvious to pick out the pairs who, after months of nest attendance and chick feeding, can now focus on themselves.

Handy from the observers point of view as confirmation of old and new pairings was achievable. Pyrrho, for example, had been involved with a young male (and his sister!) although two seasons of nest-building had got her nowhere. Now she is preening and foraging with Duke. Lets hope she will have more success next year.

Pyrrho evidently has a new ‘man’ in her life -Duke. Photo by Liz Corry.

Having more time on their hands allows them to explore the Island. With the run of good weather making winter still feel like a distant memory, the choughs have been visiting their favourite spots as well as discovering some new ones. Well at least new to our knowledge.

Les Landes is their go to for guaranteed sun, sea, and soil invertebrates. A bounty of leatherjackets and dung beetles has meant that half the group have not bothered to return to Sorel for supplemental feed. We may even have a new roost site or two on the north-west coast.

A record number of 31 choughs were spotted this month at Les Landes (please let us know if you think you have seen more). On the ground they are difficult to count when mixed in with crows. Once in the air they can reach heights the crows can’t, or at least can’t be bothered to. There are not many places in the British Isles where you can see 31 choughs circling on the thermals.

Two were at Petit Plémont at the same time as the Les Landes group leaving 13 unaccounted for. Confirmation of all 46 choughs alive and well has not been possible this month. This is not necessarily a bad thing. It marks a turning point in the project. The birds are finding new areas to forage, possibly new territories. Supplemental food is, at present time, not essential for every individual. The crucial thing is that it is there waiting at Sorel in case they need it.

Improving supplemental feeding methods

The choughs have been trying out different designs of food-hoppers over the past month. Up until now we have used either traditional ceramic dishes or guttering (yes guttering) to hold the supplemental feed. Whilst the latter was an improvement, in terms of reducing competition between the choughs, it still had drawbacks.

A new design is needed to address the ‘3 R’s of Sorel’: rain, rodents, and ruddy magpies. Don’t get me wrong, I have nothing against magpies per se. The problem is that they need to understand the concept of sharing equally.

Taking advantage of a choughs’ slender bill to design a magpie proof feeder. Photo by Liz Corry.

We can take advantage of the choughs’ slender bill to get around the magpie problem.

Holes of varying sizes were drilled into boxes filled with pellet and mealworms then filmed to see which were used by the choughs.

The design also needs to account for the length of the bill. Optimal sward height for foraging choughs is 5cm. The feeders need to be slightly less than this.

Understandably the larger holes are favoured as they allow quick easy access. They can use the smaller holes evident by the empty boxes the next day. The magpies can’t. Images of perplexed magpies were caught on camera.

Camera trap images have shown the magpie-proof designs working so far. Photo taken on Apeman camera trap.

To date we have no images or videos of rodents trying their luck. If they do have a go there are simple solutions to stop them.

Placing feeders off the ground using materials they cannot grip prevents rodents from climbing onto the boxes. Plumbing pipes come in handy for that sort of thing…and gives a shopper in a DIY store a whole new perspective on things.

A timed-release hopper would be advantageous from a staffing point of view; it wouldn’t require someone going up every day of the year.

An automated pet feeder was a hit with the choughs…and magpies! Photo by Liz Corry.

The choughs took to a model of cat feeder straight away. Camera trap footage shows them waiting around for the lids to open. It also shows them  going back at dawn to check in case it magically refilled overnight.

A combination of the above designs would be most efficient. Especially one that could cope with the coastal weather. Oh and barn owls….

Inter-Island Environment Meeting

The Inter-Island Environment Meeting (IIEM) was held in Jersey this year. The two-day event took place at Crabbé on the 20th and 21st with optional field trips around the north coast.

A field trip to Sorel on the Thursday afternoon allowed the delegates to see first-hand the work undertaken by Birds On The Edge. Annoyingly most of the choughs were having far too much fun over at Les Landes.

This year’s meeting theme was partnerships and their importance in the success (or failure) of conservation work. A poster was presented showing how stakeholders, such as Ronez Quarry, have played a role in the chough reintroduction.

All the presentations demonstrated just how well effective partnerships can benefit conservation work both on land and sea. With talks about turning the tide on plastic waste, monitoring human disturbance at the Écréhous, and how Guernsey’s gardens are providing a lifeline for pollinators.

There was even a talk on Montserrat by the UK Overseas Territories As someone who has lived and worked in Montserrat it was a nice surprise. It was also nice to see some familiar faces in the video shown by Alderney Wildlife Trust highlighting the benefits of a good volunteer programme. Two of those volunteers were past chough project students!

Red-billed choughs in Greece

Glyn Young missed out on the IIEM. Don’t feel sorry for him. He was attending the European Association of Zoos and Aquaria (EAZA) annual conference in Athens. Several of Jersey Zoo’s staff travelled to Attica Zoological Park for the four-day conference. Glyn gave a presentation on the chough reintroduction and the successes to date.

Chough names

Thank you for all those who suggested names for this year’s chicks. Some suggestions have already been used, sadly on birds no longer with us. We have gone with Bumble and Bee for one brother and sister clutch. Nothing to do with a secret love of Transformer toys,rather their black and yellow leg rings. We also liked the suggestion giving recognition to Jersey’s Lily Langtry and have gone with Lily and Lotte (her middle name was Charlotte) for the two unnamed sisters.

What is a “cough”?: A study into childrens’ awareness of Jersey’s chough project

By Catherine Firth

Public awareness is essential if a conservation project is to succeed, particularly with species reintroductions. There was initial concern from the public when the idea of reintroducing choughs to Jersey was mentioned. Crows and magpies, close relatives of choughs, are considered pests by a lot of Islanders and can be controlled under Jersey law in order to protect agricultural produce. Choughs are highly specialised feeders only eating insects you tend to find in soil or animal dung.

Public understanding and acceptance of choughs was, therefore, needed to ensure success.  In addition, support for the choughs should lead to support for the wider Birds On The Edge project. In turn attracting funding and resources such as public volunteers.

It has now been five years since the first choughs were released into Jersey. We wanted to find out if the Jersey public were aware and what they thought of the species. Two studies were conducted this summer by visiting graduate students; one focused on children, the other on adults.

I focused on children as they are a key demographic group at Jersey Zoo.  By engaging children in conservation education, they can be inspired to make well informed decisions affecting sustainability in the future, and in this case help to protect the red-billed choughs in Jersey.

To conduct the study, I visited eleven of Jersey’s primary schools with a questionnaire for the children to complete before and after an educational presentation on the  choughs and  Birds On The Edge. Being a Nottinghamshire lass, navigating the back roads of Jersey on a rusty borrowed bike was a challenge in itself!  But after a lot of wrong turns and frantic pedalling up and down hills, I manged to interview 16 teachers and 330 children across the Island. Teachers were generally very enthusiastic about including their classes in the study and the children seemed excited to learn about a new mysterious animal.

Reintroduced choughs and sheep in Jersey have been working together to improve the Island’s biodiversity. Photo by Liz Corry.

The results showed that only a very small percentage of the children interviewed were aware of the red-billed choughs in Jersey.  A proportion of the children guessed that it was a bird, but hardly any knew that choughs were living on the same island as them.  In fact, I had a lot of children reading their questionnaire and asking me “what is a cough?” accompanied by some fantastic drawings of what the children believed the choughs to look like including sloths, hedgehogs, monkeys and even a unicorn!  Likewise, most teachers confessed that they did not know about the project.

After the educational presentation, the results showed a huge increase in knowledge and understanding both of the choughs as a species and its history in Jersey. In their post-taught questionnaires, many children mentioned how the choughs became locally extinct, the habitat and resource needs of the choughs and what Birds On The Edge is doing to help. In addition, after the visits, there was some evidence of children sharing their new found knowledge of the red-billed choughs with other parties. This included two boys attending the chough keeper talk at Jersey Zoo, given that day by the Head of Birds, and practically presenting it for him!

There were other cases of children telling their parents and one child even identifying a chough on a family walk in St John!  This is very encouraging news, demonstrating how children can act as a catalyst for change by sharing their knowledge to influence their friends’ and family’s actions which affect conservation matters and help protect the choughs.

Moving forward, it would be fantastic to do more in-school workshops. Only a small percentage of the children in Jersey took part in the study but it showed how children can be massive assets for increasing awareness. It would also be great for teachers to include the choughs in more of their own lessons; a fantastic example of animals and their habitats which is a part of the Year’s 3, 4, 5 and 6 science curriculums.  However,  teachers had concerns about the time available to them to teach their classes about the choughs (particularly Year 6 teachers who face the pressure of SATs). To overcome this, we could provide schools with more resources, for instance red-billed chough reading comprehension resources: infiltrating classes without directly teaching about choughs whilst remaining focussed on the children’s upcoming exams.

As part of my workshops the children created posters to inform the public of Jersey all about the red-billed chough population, all completed posters were entered into a competition and were judged by a member of the Jersey Zoo education team. Grouville Primary School had the winning poster and the class had the opportunity to visit the choughs at Sorel.

All entries were fantastic and can be seen here.  A big thank you to all the children who took part and the teachers who sent in all the entries!  Everyone at the Zoo particularly enjoyed this poster from Grouville:

Fifth International Red-billed Chough Meeting. Segovia, Spain, 10-11 October, 2019

At the Fourth International Workshop on the Conservation of the Red-billed Chough held in October 2013 in Vila Real (Portugal), it was unanimously expressed that the next workshop should take place in Segovia, Spain. Segovia is not only beautiful but it is also full of choughs amongst the famous buildings. What better place?

Foro GeoBiosfera in collaboration with the National Museum of Natural Sciences of Madrid (CSIC) and with the support of the City Council of Segovia, announces the holding of this next Workshop, inviting all interested parts to participate.

This is the first call of the Workshop. In the near future there will be complete information on aspects of the event including the precise location of the meeting, communications by road, bus, train and plane, places of accommodation, registration fees and scope of services offered. The organisers will also answer questions that the participants may generate.

This Workshop is open to all interested people, professionals and those from public and private institutions alike who are keen on choughs, both red-billed and Alpine (yellow-billed) choughs.

Communications from any part of the world are welcome covering different aspects related to choughs, including:

  • Research and monitoring
  • Conservation
  • Cultural: literature, history, music and exhibitions of painting, photography, crafts.
  • Education and dissemination
  • Protection and legislation.

Jersey’s favourite farmland birds – on stamps

As part of its Links with China series, Jersey Post issued a new set of commemorative stamps this month featuring farmland birds common to both China and Jersey. Amongst the old favourites like goldfinch and swallow we are proud that four of the species most important to Birds On The Edge, stonechat, yellowhammer, linnet and red-billed chough have been included.

That the red-billed chough should feature on a stamp only five years after its ‘return’ to the Island in 2013 is testament to a lot of very hard work from a lot of people in the Birds On The Edge partnership and even more people who have been enthused by the project to help Jersey’s declining farmland birds. We must now hope that the yellowhammer, which last bred in Jersey in 2005, will also one day be a feature of our north coast again.

Other stamps in Jersey’s Links with China series include butterflies, garden flowers and waterfowl. See the full range of farmland bird stamp products available here

Chough report: August 2018

Zoo choughs

Keepers were in shock this month after the loss of two choughs in the Zoo. On 8th August a male was discovered by a keeper on the floor of the aviary. From his physical appearance, staff assumed the chough had been in a fight with Tristan, the only other male in the group, and lost.

The male chough had x-rays taken to assess injuries. Photo by Liz Corry.

When a second chough, Issy our breeding female, became ill we suspected there was more to it. The male’s condition gradually worsened despite efforts and eventually the bird had to be euthanased. Sadly, the female died a few days later.

Andrew Routh, Head Vet, explains “We took blood samples that were analysed in-house, at our usual diagnostic laboratory in the UK and, additionally, forwarded on by them to a specialist also in the UK. We will be re-sampling the remaining three birds in the collection. Full post mortem examinations were carried out on both birds and a comprehensive set of tissues from each sent for analysis by board-certified pathologists in the UK. No conclusions yet on the cause though further tests are pending.”

The remaining three birds have been taken off-show to individual enclosures for close monitoring. So far, they have shown no signs of ill health, are eating well and chatting loudly. Gianna, the Italian diva that she is, is a tad miffed we have taken her away from her public. Hopefully we can return them soon at which point the chough keeper talks will resume.

Wild chicks update

The last unringed wild chick was caught up on 1st August to be fitted with leg rings. Whilst in the hand, the chick made noises we’ve never heard before. And no, it wasn’t because we were squeezing too hard! There is debate as to whether the sounds were more gull-like or goose-like. Either way the ‘meeping’ chick became the first of the 2018 group to be named – Beaker.

The last of 2018’s chicks to be ringed (left!) and his namesake Beaker (right) – both emit unusual sounds. Photo by Elin Cunningham.

Two weeks later the DNA results returned form the UK lab. Whilst teenagers across the land were jumping for joy over their exam results, we beamed with delight upon hearing we have five males and four females.

This is great news for the Jersey population because:

(1) The sex ratio for wild-hatched choughs in Jersey is now 1:1. For the entire flock, it is more like three females for every two males. Not quite as catchy. Still a good result;

and

(2) We can name the new chicks! Aside from Beaker we had names lined up for Dusty’s chicks. In honour of Ronez’s assistance with the project, the three boys are now known as Clem (who found the chicks), Toby, and Osbourne (Ossy for short).

Tempting as it might be to call Beaker’s sister Dr Honeydew, her name is still open to debateWe are still searching for appropriate Jersey-related names for four females and a male. Please use the comments box to put forward any suggestions.

Spreading their wings

The flock have shown a distinct change in behaviour this month. After the chaos over June and July when chicks had to be fed and wild food supplies had dried up, the adults are relaxing back into their normal routines. One fortunate member of the public snapped a photo of 30 choughs flying over Plémont. On the back of this, social media reported seeing ‘large’ groups back at Les Landes.

The change is partly due to the chicks becoming independent and feeding themselves.

A major factor will be the rise in wild food supplies thanks to the shift in weather. Leatherjackets in the soil and dung-loving insects will provide the calories needed to fly back and forth around the north-west coast.

We are seeing an average of 24 choughs at the supplemental feeds. They appear to be the same individuals; all families bar Lee and Caûvette‘s making up half the group. Their willingness to enter the aviary has taken a knock since the recent spate of catch-ups. We have to reassure them that entering the aviary does not always result in humans waving nets around.

Having a wild food source around provides them with options. Great for them. For staff not so much, as it means the birds are less likely to hang around the aviary. Health screening, weight checks etc. are not as easy.

Now you sheep me, now you don’t

Lack of choughs at the aviary is being compensated by appearances of sheep within the perimeter fence. The first sighting was on one of the hottest, driest days of the summer. A young sheep was happily curled up in the shade of the aviary sheds munching on lush green grass whilst the others were lined up along the hedgerows competing for shade. Much to the sheep’s dismay it was returned to the flock.

The next day it was back! And once again returned to the flock. A day or so later a different sheep was present. Neither student or I could figure out how on earth they were getting through the locked gate and wire fencing.

Days passed, sheep were absent. Or so we thought. Camera-trap footage to investigate chough roost activity threw up a different mystery. A ewe present in the morning, had gone by the afternoon. Clearly they were playing games with us.

Camera trap image inside the aviary showing a sheep within the aviary perimeter.

They upped the stakes in the last days of August. Having hidden in the bracken, ‘Houdini’ found her way inside the aviary. True magicians never reveal their secrets – except when their hooves and horns knocking equipment over in the keeper-porch give them away. I had left both doors open, not expecting her to follow me in, but it meant she could safely hang out in the aviary until the shepherd reached Sorel. And saved me a job with the lawnmower.

Yet another prime example of how the conservation of one species can benefit others.

September volunteer activity

Sunday 9th September 2018 – Victoria Tower, St Martin – 10:30-13.00

From Jersey Conservation Volunteers

Well hasn’t it been an amazing summer? However, the signs of autumn are becoming apparent, sloes, blackberries and of course the Jersey Conservation Volunteers!

The details The first task of the season will focus primarily on sycamore control. Sycamore Acer pseudoplatanus is a deciduous broadleaf tree native to central, eastern and southern Europe. It was introduced to the British Isles and is now a naturalised species.

While sycamore trees do have a value to wildlife, they are so successful that they have a tendency to take over. The purpose of this task is to control the abundance of sycamore at the site by cutting back and, where possible, uprooting young self-seeded saplings.

If you have any questions, or if you wish to be added to the Jersey Conservation Volunteers email list, please contact either Julia Meldrum (tel: 441600; j.meldrum@gov.je) or Jon Parkes (tel: 483193; jon.parkes@nationaltrust.je).

The site  We will meet in the car park at the end of Le Mont Mallet Jersey Phone Book map Map 11 MM15 – Google maps here

Parking Parking at the site is very limited but further on road parking is available along La Rue de La Pouclee et des Quatre Chemins. Please also consider car sharing or cycling.

The task We will be managing the sycamore woodland by cutting back older trees and uprooting saplings.

Meet at 10.20 promptly for a 10.30 start. We will be finished work by 12.30 for well-earned refreshments.

Tools needed Tools will be provided but if you have a pair of gardening gloves, a spade and cutting tools (e.g. pruning saw, loppers, secateurs) it would be helpful if you could bring them along with you.

Clothing needed Good thick gloves (though we can supply a pair if you don’t have them), wellies or sturdy boots, (it shouldn’t be muddy but the vegetation may well be wet it and it may be rough underfoot) and common sense clothes to cope with the elements, we go ahead whatever the weather!

Children All are welcome, young or old. Children under 16 must be supervised by a parent or guardian during the task.

Refreshments Kim the Kake has spent all summer baking for us (well perhaps not) but she will thankfully be on hand at the end of the task to dish out hot drinks and her scrumptious homemade cakes.
