January got off to a flying start. For the choughs at least. We, however, are still grounded in lockdown.
Jersey has experienced some outstanding days of clear skies and sunshine. The type that provides perfect flying conditions for choughs. Then we’ve had the horrendous downpours. The type that provides perfect conditions for staff and student to question their career choices.
Let’s start the year focusing on the positives!
News from Carteret
After a nervous few days of not seeing her, Yann happily reported Cappy to be alive and well. She is still in the same location. A good sign perhaps if she is confident with her surroundings; familiar with the good foraging spots and has secured a safe roost. We don’t really know right now. Counting down the days until we can visit. January’s skies provided teasing glimpses of French shores.

New year, new bling
There have been three attempts this year to trap choughs in the aviary to replace missing or broken leg rings. Third time’s a charm! We changed tactic for 2021 and sat in front of the aviary posed ready with the hatch wires.
The first time was inevitably going to fail. The birds knew something was afoot and refused to enter the aviary in our presence. Throughout the next week of feeds, observations were carried out from this position without any movement of hatches. By the second attempt the birds were a little more relaxed. A few of the bolder adults like Chewbacca, Lee, and Green went inside. Most of the group would then follow having seen the survival of the ‘sacrificial offerings’. Any sudden movement or unfamiliar noise and the entire flock fled.
Another week of undisturbed feeding meant that the third attempt trapped 24 of the 29 choughs present that day. It still meant a good thirty minutes of sitting patiently in the dead bracken due to hyper-vigilant Bo and Betty. These were two we needed but kept landing on the shelf, walking in and out of the open hatches, always keeping an eye on me.

The weather on that day wasn’t as nice as the photos make out. High winds kept blowing the hand net back in on itself giving the birds the advantage. That said, we achieved a lot. Betty, Flieur and her youngster Iris had their missing colour rings replaced. Betty and Vicq were given fresh red and white striped rings as their existing ones had shattered. We swapped Portlet’s pale blue for a new style of pale blue that makes it easy to distinguish from the whites and greys of the flock.
Finally, Dingle was caught up simply because he was unlucky. Trying to isolate five from a group of 24 in a confined space is guaranteed to result in by-catch. All six looked well and had healthy body weights.
Away from Sorel
A few unidentified choughs evaded capture which was a shame as there are a couple of outstanding cases to deal with. Clearly, with a population of 42, several were absent from Sorel that day.
We are still seeing choughs in Trinity Parish, Plémont, Les Landes, and the south west of the Island. Rather worryingly, we no longer get reports of pairs, just of single birds.
Twice in one week we have seen a chough fly over the Zoo. The first time was in the rain. It looked rather laboured in flight and called frequently. The second visit was again on a damp, grey day. This time it was spotted taking a break perched atop a leafless tree by the macaque enclosure. It was, sadly, unclear if it was the same individual.
Beaker, one half of the Plémont pair has not been seen of late at the feeds like his female has. A roost check confirmed only one bird going in to roost. We need to continue monitoring this as it implies we are down a breeding pair and territory for the 2021 season.
There are growing concerns too for a couple of other birds which may mean we have lost two more breeding pairs.
COVID, and corvid, conundrum in the Zoo
One pair who have not changed are the Zoo pair. Tristan and Penny will want to start nest building towards the end of February. This means we need to move their three juveniles out before Dad gets, well, violent. No other way of putting it.
The default move would be to export them to the UK to join the captive breeding programme supporting the pending Kent reintroduction. COVID travel restrictions set the ferry option back until April and commercial flight option to a similar date.
Plan B then becomes holding them in an aviary at the Zoo until Plan A is feasible. However, thanks to the knock on effect of COVID postponing 2020 exports, and our breeding success of species with similar housing needs (e.g. hornbills) we find ourselves in a Battle Royale for aviary space.
There is a Plan C formulating – release the juveniles. Very much dependent on whether staff can dedicate sufficient time to ensure the best chances of success. Then we have the ongoing rat problem which would really pose a threat if you want to keep birds captive whilst conditioning them for release.
Rats caught on the camera trap at the aviary (for scale, it climbs half inch squared mesh).
A Jersey supplier has been found for the rodent-proofing aluminium mentioned in the last report. I’m not confident that this can be supplied and fitted in time before Tristan kicks off. Watch this space!

Summary of the 2020 breeding season
We have ringed a total of twelve chicks this year from seven different broods. Three chicks have unknown parentage although I can narrow it down to three possible options. We also know that five chicks died bouldering or shortly post-fledge which brings the 2020 total to seventeen chicks. No doubt we would have recorded more if COVID-19 restrictions had not prevented us for checking in nests. In a way it doesn’t matter. The twelve that fledged and continue to fly around Jersey are the important thing.
Last month’s report sounded like we had a handle on which pairs had bred and which chicks had made it to the aviary for supplemental feed. We didn’t. Not entirely. None of the chicks had been ringed in the nest this year thanks to the pandemic situation. On some days there were numerous unringed, identical birds in the flock.
On 23rd June, Glyn opportunistically caught up two of the unringed chicks to pop on a plastic leg ring. Six days later I caught up four chicks with a licensed ringer including one Glyn had previously caught. We fitted them with the full complement of rings and took DNA for sexing.
Choughs very quickly wise-up to any catch-up plans. Repeated back to back catch-up attempts result in the birds avoiding the aviary. Which meant it took all of July (and the first week in August) to finish processing all of the unringed chicks.
As the month went on, we started to get a clearer picture on parentage. However, the longer you wait to ring a chick the more independent it becomes, i.e. feeds for itself. You need to see an adult physically feeding a youngster to know it is the parent. Of course, there is another risk with waiting. An unringed chick seen at the start of the month might get predated, fatally injured etc. and won’t be around by the end of the month. We certainly experienced that with Dusty and Chickay’s brood.
The twelve that survived bring the total wild population back up to 44 after the dip in 2019. We look forward to monitoring their progress.
One of the more memorable ringing events occurred on 16th July. I had completely different plans that day taking a film crew to Sorel along with a colleague, Dan, to film a piece for our Love your zoo LIVE event. As we arrived, I spotted an unringed chough in the aviary. Not only that, but it was also a new arrival. You can tell by their naivety when they are inside the aviary. Instead of navigating the open hatches and flying straight out they fumble around in blind panic if spooked. Trapping it and catching it up was super easy. There were no licensed ringers available at short notice to fit the metal ring, so we did the rest.
Dan was very excited especially when he found out he was going to be my glamourous assistance. I let him pick the ring colour with a caution of anything but pale blue or grey (hard to distinguish in the wild). He went with pale blue. Despite that we have named the chick Danny. The sexing result came back as a male just to add to the significance.
We spent two and a half hours filming out at Sorel that day. As expected, a lot ended up on the cutting room floor. Here is the video for those who missed it.
Zoo chicks take flight
The three youngsters left their nest box at the start of July. The first was out on the first! They look really good and follow mum to the ground looking for food. Still insisting mum feeds them, but watching and learning all the time when Penny is foraging for worms, larvae etc. We are lucky that the Zoo aviary is home to a few ant nests. As long as we time it right, we can turn over a stone and have hundreds of eggs available to the choughs. They just have to make sure they get to them before the ants have carried them away.

Sexing results came back on the 17th confirming we have three males. Two firsts for the Zoo; three chicks fledged, no females. These boys will head to the UK early next year to join either Paradise Park or Wildwood‘s breeding programme.

Chough travel plans continue despite Covid-19
Beaker and Beanie Baby continue to visit Grosnez and Les Landes whilst roosting at Plémont. They even made an appearance at the Sorel feed on 28th July. Maybe supplies were running low over in the west?

Someone is certainly enjoying the east of the Island. More reports from Les Platons, Bouley Bay, Trinity, and flying over St Martin’s cricket pitch. We have Dave Buxton to thank for the latter. Licensed ringer and avid cricketer.
The pitch certainly looks inviting to a chough with all that short grass. The question is what lies beneath? Juicy grubs?

Breeding out on the north coast has been in full swing this April. Thirteen nest sites have been recorded, two of which are new. We have a new site within the quarry and for the first time a nest-box installed along the north coast is seeing action. Sadly it looks like a territory in the south-west of the Island has been lost, but with 13 of our 15 males in action things are still looking good.

Ronez: same sites, different pairs
Working closely with Ronez Quarry staff we have been able to record eleven nests on their property.

It does look like we have lost Bean and males Q and Duke. Their ‘other halves’ are using the same nest sites they had last year this time with new partners.
All nest-boxes installed in the quarry are now being used and show promise. With help from quarryman Kevin Le Herrisier, Red and Dingle have been encouraged to nest in a box rather than on the hot pipes that cooked their eggs for the past two seasons.

Two external boxes are once again in use and are already having more success (now that they’ve evicted the kestrel). One of these boxes is being used by wild-hatched Percy and Icho who was released in 2014.
The really exciting news came from Toby Cabaret, Assistant Operations Manager. He reported hearing chick noises from the box. Considering it took a hydraulic crane to put the box up in the first place, Toby was a little unsure of what he was actually hearing.
You talking to me? Photo by Liz Corry.
I spent an hour observing the nest site from the newly installed viewing platform in the lower quarry. Accompanied by an inquisitive gull, I watched as Percy made four visits to the nest-box within a fifty minute period.
Either Icho is one demanding female or they have chicks. This was on the 11th which meant Jersey’s choughs had started early!
North coast nests
Once again, Earl and Xaviour are nesting out at Plémont. Visitors to Plémont Beach cafe are having regular flypasts if they spare the time to look up from their all-day breakfasts. This is the first nest site away from the quarry and is susceptible to human disturbance. The public cannot access the nest itself, but they can access the headland above even though part of it falls within the Seabird Protection Zone in place March to July. Low tide fishermen, walkers, drone users, and a gentleman in red speedos who takes a folding chair out to the furthest point on a regular basis so he can sunbathe – the downside to having a good spotting scope – have been noted in the vicinity.
This has not deterred the pair from nesting, in fact we believe Xaviour is incubating eggs. The concern will be around fledging time when chicks are vulnerable and learning to forage on that particular headland.
As well as this natural nest site, we have nest-boxes along the cliffs stretching from Sorel to Devil’s Hole. One of these has been destroyed by rockfall (hopefully not with birds inside). Another has been used for the first time as an actual nest rather than rain shelter. Vicq, one of our foster-reared girls and now fully fledged ‘cougar’, has taken a shine to one year old Osbourne. As Ronez’s CEO namesake, I guess he was destined to be the first of the 2018 wild-hatched choughs to pair up.

When Vicq and Osbourne were seen for the first time using the box they were very attentive. They had already built the nest. Vicq was clearly very busy inside whilst Osbourne maintained a supervisory role (or didn’t have a clue what was happening). The next day they were still visiting the box albeit less frequently. A visiting student, Rachel Owen, observed the nest for a set time each day for the following week. Nothing! Not a single visit to the box by a chough. Vicq‘s first nest had failed; certainly one to keep an eye on next year.
Another failure this year has been the nest in the south-west of the Island. In fact the pair have not been seen at all this season by staff at Simon Sand & Gravel Ltd. I was beginning to get paranoid having visited the area a few times this year on a chough hunt and returned unsuccessful.
Student Rachel Owen, who was staying with friends in Corbière, spent two mornings walking the coastal path from Gorselands to the sand dunes. Again no choughs. Several other corvids around to test her ID skills, but clearly the pair who tried holding down a territory in this area last year have abandoned. Pleased to say Rachel stayed upbeat about it despite the miles she covered on foot.

Whilst we have no strong scientific data, we do know the pair returned every day to Sorel throughout 2018 to get food before roosting back in the south-west. Compare that to the Plémont pair and you can’t help thinking that the south-west provides a poor food resource. The other factor to consider is the unintentional human disturbance. The number of visitors to Corbière and the dunes meant the choughs were constantly moving around whilst foraging.
The sad news is that the female, Mary, has not been seen since the start of February. Partner Bo had a similar attendance record until we discovered he had just been incognito. He was one of two individuals we reported on last month for having identical leg rings. Bo is currently nesting in the quarry with a different female.
There have been several confirmed reports of choughs exploring the north-east of the Island. On the first Sunday in April, Glyn Young watched a pair fly between la Saie and le Coupe Bays. About an hour earlier, one of our keepers living near the zoo had spotted them flying in Glyn’s direction. The following weekend, a local birder recorded a pair near Anne Port, briefly stopping at Gorey Castle before heading west. The weekend after that I was alerted by a distinct call coming from the skies above my house! Two choughs meandering along on the thermals above Rozel Valley.
Are these weekend visitors? Presumably the same pair, if so which? To add to the mystery, another Durrell colleague reported four flying over her house east of the zoo on a Tuesday morning.
I contacted Jersey Heritage regarding the sighting at Gorey castle. To a pair of passing choughs, the 800-year old building offers numerous potential nesting opportunities. A volunteer guide at the castle witnessed the same visit, but nothing else before or after. It doesn’t necessarily mean that is the end of the story.
There are plenty of foraging opportunities in the north-east if you look around. Rozel Manor for instance has land grazed by cattle. Nearby there are two smallholdings with pigs which get rotated around (field not pig!) so the land isn’t completely churned up. Plus plenty of large, horse paddocks as well as properties with extensive, well-maintained lawns. Providing pesticides are not being used there could be an untapped source of food for the choughs.

Sorel aviary ‘spring clean’
Much needed major repair work was carried out this month on the aviary at Sorel. We experienced a few setbacks in suppliers and contractors resulting in Durrell’s own Site Service team carrying out the work with a very short turnaround window.
We called in a favour with the Natural Environment team. States ranger Keiran drove the building materials and equipment to Sorel as we don’t have a suitable vehicle.

Brand new netting has been fitted to the tunnel. Not a simple job as the timber framework it was attached to was rotten. All of the shelving in the tunnel has been replaced and most of the framework. It also meant that the hatches had to be removed, new marine-grade steel hinges fitted, and finally re-wired before fitting.

A metal pole has been installed running down the centre of the tunnel to support the hoops.
This was the original intention back when the aviary was first built, but never came to fruition.
Timber was used instead, which of course didn’t weather well and in certain places led to netting fraying.
There are still several DIY tasks that need to be completed in order for the aviary to function as a catch-up facility. It is, however, up and running again as a supplemental feed site and roost for those birds that need it.
Jersey Zoo’s breeding group
This year we have just one breeding pair of choughs in the zoo; Tristan and Penny (short for Pendragon). This is their first time together not that you can tell. They have made a perfect nest and began egg-laying on the 19th. Mum is tending to a clutch of four eggs with Tristan keeping her well-fed. We have to wait until May to see if they all hatch.
Gianna is still at the Zoo although now off-show in her foster-rearing aviary. We haven’t broken the news to her yet that we want the other pair to parent-rear their own chicks. Gianna hasn’t built a nest this year which is unusual. I think it is linked to the lack of attention she is receiving. The project has been without a student placement for several months now. Normally they would be visiting Gianna two to three times a day in addition to the keeper visits.
Any other business….YES loads!
April was definitely a busy month. To add to all of the above activities there have been several visitors all wanting to learn how the reintroduction and Birds On The Edge can be of benefit. Below is a summary although really they warrant separate blogs. In no particular order:
Author Patrick Barkham and his family spent the Easter Holidays at the Durrell Wildlife Camp. He managed to include a trip to Sorel where I could explain the work we do and show off the choughs. Inadvertently, Patrick helped with our data collection. As I stood on the cliff tops pointing to a nest-box and commenting on the lack of uptake, Vicq and Osbourne eloquently flew straight inside! Side note: highly recommend reading Patrick’s books, especially Islander and Badgerlands.

Jersey zoo played host to the European Association of Zoos and Aquaria (EAZA)Directors’ Days conference. Over 130 zoo directors travelled to Jersey for the three-day event. This year’s theme was around leadership in conservation and how to encourage the community to set ambitious targets for greater conservation impact. The Birds On The Edge project was therefore a fitting optional field trip for the final day.
On the same day we also welcomed two guests from the Scottish Chough Study Group – Pat Monaghan, University of Glasgow, and Amanda Trask (now at ZSL). We are assisting in planning a translocation intended to ensure the survival of the remnant Scottish population. Also supported by improved supplemental feeding methods adapted from the lessons learnt with the Jersey choughs.
The two groups met out at Sorel providing Pat and Amanda with a bonus opportunity to network with Scottish EAZA members! Watch this space!

Lastly, I escaped the rock for 24 hours to attend a workshop at Dover Castle, Kent. A PhD student is currently assessing the feasibility of reintroducing choughs to Kent. Historically, the species resided across the entire south coast of England not just Cornwall where you find them today. Plus choughs feature heavily in Canterbury heraldry.
The workshop was an opportunity to get project partners and experts together to discuss the next steps. Our good friends from Paradise Park were present allowing for a quick catch-up. There was a lot of enthusiasm in the room driven by Kent Wildlife Trust‘s latest goal to develop a wilder Kent. Again watch this space!
In the meantime, watch this video and reward yourself for reaching the end of April’s report!
The grazing flock of Manx loaghtan sheep at Sorel have been confined to National Trust fields for the past few months.
The shepherds have been busy preparing for the lambing season, moving rams and ewes around Jersey.
Lambing season is now upon us.
As of last week, a large number have been allowed back out to roam freely between Sorel Point and Devil’s Hole. A reminder to our Jersey readers and anyone visiting, please remember to close gates behind you whilst on site. As you will see from the video below, sheep will be sheep. We don’t want them following you back to the car park.
And one last plea – do go and visit them at Sorel. Not only are they endearing, you get to see conservation in action too. Plus the science boffins have proof: Sorel sheep are good for the soul! Trust me, read these:

It was a wet and windy start to 2018 with storms Eleanor, Fionn, David, and Georgina all battering Jersey within a span of 24 days. Not surprisingly then, there is little to report in terms of chough antics. Even less in the way of photos since cameras were kept locked away in the dry.
Wind speeds, rarely falling below F8 throughout January, took their toll on the aviary. The poly-tunnel netting suffered the most. Constant rubbing along the metal poles wore down the threads and cable ties snapped. In some areas joins in the netting opened up or came away from the wooden frame and overnight a large split in the middle of the poly-tunnel appeared. Obviously reducing the effectiveness of trapping birds in the aviary if we had a need to do so. An ostrich could escape from that, never mind a chough!
Netting ripped open and posts broken as storm after storm pounded the aviary. Photo by Liz Corry.
Easily rectified by sewing and patching with extra netting, the tricky part was finding a day when weather conditions permitted use of a ladder for the harder to reach areas. Other damage has or will take longer to repair. Again this is because we are reliant on weather conditions favouring truck access to the site to take new timber and scaffolding.
As exemplified by this little incident on the one day it didn’t rain…

Yes we did have 4WD on. No it obviously wasn’t working and we are eternally grateful to staff at Ronez Quarry.
My aviary and other animals
The aviary still functions as a supplemental feed station and roost site. As mentioned in past monthlies it is favoured by other wildlife. We probably have the complete compliment of Jersey’s small mammals visiting the aviary. This has pros and cons depending on your viewpoint. The owls and kestrels are very much in the ‘pro’ camp.
One afternoon our volunteer was shocked to find an owl flying around inside the aviary. As were the choughs! Normally we just find pellets. Earlier this month we thought we had stumbled upon a lost Damien Hirst masterpiece. Turns out it was just the neatly displayed insides of a rat.
We have also managed to film the culprit responsible for the defecation and destruction found in the keeper porch. Measures are underway to deter this behaviour.
We are experiencing problems using camera traps. A lot of the time they failed to even record chough activity. Fingers crossed we get more footage of the owl(s) if it or they return.
Camera trap photo taken at dawn of the choughs who chose to roost at the aviary.
Sign of the times
Despite the wind and rain the chough pairings are still clear to see. We are not far away from the time of year that the pairs start nesting. We are keeping a close eye on the existing pairs as well as the blossoming ones. Our two trios from last year will or have changed.
The death of Egg has forced Dusty to consider whether he becomes closer with Chickay or ditches her and starts afresh. Our young trio of Pyrrho and two wild siblings remains a close friendship. Pyrrho wants more. Will the young male feel the same this year now he is a year older with his hormones beginning to kick in?

Who ewe looking at?
Apologies, but how else to entitle this section? The sheep are still confined to the field adjacent to the aviary. They started to take a keen interest in the grass surrounding the aviary but weren’t invited in! They have now been partitioned off to the next field. The choughs, however, make the most of the sheep’s field and the soil, dung, and hay there teeming with invertebrates.
The grass IS greener. Photo by Liz Corry.
The field gates are currently padlocked if you are to go and visit. Please be respectful of the sheep whilst they are up there: they are very friendly, but spook easily which tends to result in Usain Bolt sprints in all directions.
Advances in aviary design
Finally this month we have to thank John Corder, a follower of the monthly report, who answered a plea in December’s report. I had asked if anyone had suggestions for a more efficient way of building and operating release hatches. John linked us to a presentation made at the Association of Zoos and Aquariums 2016 conference describing the use of remote bird traps. These homemade traps incorporate remote central-locking systems used in cars and run off a 12v battery. A quick visit to eBay and a local hardware store soon had me set up to finally put my A-level in Technology to good use. The kit cost around £30. All that is needed now is to find a way of making it weather-proof and workable at Sorel. We hope to test this out in our zoo aviary first. Many thanks to John once again.
Efficient release hatches? We think not! Photo by Elin Cunningham

As October drew to a close it was achingly apparent that the chough flock was down from 38 to 36 individuals. The two wild-hatched females who went missing in September had still not made an appearance, forcing us to reluctantly record them as missing presumed dead.
This is the first time we have lost wild-hatched birds post-fledging period. One can’t help feel a sense of responsibility. These individuals were known to have a nematode infection, but attempts to medicate them had failed before they went missing. All we can do now is monitor the remaining choughs to ensure the same fate doesn’t befall them.
So we did, and guess what…two of the adults started sneezing. Egg and Helier began with the ‘I’m not sneezing, just clearing my nostrils’ subtle sneeze. After a few days Egg stopped whereas Helier continued and progressively worsened.
After a few failed catch ups due to jammed hatches, intelligent corvids, and of all things Portuguese forest fires (see ‘Sepia skies’ below) Helier was finally locked in the aviary allowing her to be treated by the vet team. She was released back into the wild straight after her worming injection and appears to be much improved.
Nematodes are part of the natural ecosystem. Choughs feeding in the wild will be exposed to them and have to tolerate or succumb. This year is turning out to be the worst since the project began in terms of number of infected birds and fatalities warranting further investigation.
Having worked at Sorel for several years now you would have thought that everything that could go wrong in a catch up had done or at least been theorised and accounted for. Hinges sticking on trap doors, birds not showing up or not hungry enough to want to go inside, mountain bikers zooming past scaring the flock into the air, etcetera. Not once had we thought to account for Caribbean hurricanes and Portuguese forest fires!
On the morning of the first planned attempt to catch up Helier the skies in Jersey, and parts of the UK, were looking very ominous. Walking around Sorel it felt like someone had put a sepia filter on the world. Frustratingly my camera phone kept adding its own filter so the photos below don’t fully set the scene.
On 16th October 2017 the skies above Jersey turned a sepia colour. Photo by Liz Corry.
Low cloud filled the skies throughout the morning. Around lunchtime the sun made an appearance, but looked more like Mars than our beloved sun. There were no horsemen on the horizon so instead of embracing impending doom I turned to the Gods of Google.

An explanation for the near apocalyptic conditions was provided by the BBC. Remnants of Hurricane Ophelia passing over the south of England and Channel Islands were dragging dust from the Sahara and smoke from the devastating forest fires in Portugal and Spain across our skies.
I tried explaining this to a very confused flock of choughs who were clearly conflicted about what time they should go to roost. One might think this would be advantageous to someone trying to lock birds in an aviary. Nope. Instead it meant they just sat and stared at me in their perplexed state. A twenty-minute stand-off resulted in a dejected keeper walking away left to come up with a Plan B.
Plan B failed. In fact it wasn’t until Plan E was executed that we were able to lock the sick chough in the aviary. The new plan arose from the need to know who was roosting in the aviary in case we had to lock in the sick bird for longer than a day. There was a small chance she roosted in the aviary already rather than the quarry. If so, all we had to do was wait until the birds had gone to roost and quietly shut the external hatches.
Cut to the scene of a person in dark clothes vaulting a field gate at night only lit by the stars and the dim headlights from a teenager’s car (one assumes from the discarded firework packaging and soda cans found the next morning) idling at Sorel Point.
The operation provided extra information other than Helier’s roosting site. A total of twelve choughs were roosting inside the aviary including Dusty the very first wild-hatched chough and the two females who follow him.
Kevin and Bean were hanging around outside the aviary. They could have used one of the external roost spaces at the aviary or simply flown over from the quarry at first light to forage nearby. The other interesting find was the kestrel who shot out of the external roost box when I arrived in the morning to check on the choughs.
There are no photos from Operation If this doesn’t work we’re screwed. So instead here are a couple taken at Les Landes when checking for signs of choughs at sunset.

The Women’s Institute expedition to the north coast
Earlier in the year the ladies of La Moye WI had invited me to give a talk about the choughs. Several of their members were already aware of the project, but had not realised that the historic breeding sites for Jersey choughs were in fact along the coastline at La Moye.
Enthusiasm for the project continued to grow as the evening went on, fuelled by the obligatory tea and cake, and by the end of the night a trip to Sorel was penned in the diary.
After a few clashes in the calendar a small group from La Moye finally made it up to the north coast this month. Glyn walked them around the conservation fields and release site. Not all of the choughs were present, but certainly enough to make an impact and demonstrate their amazing flying skills. I sadly missed out as I was in England, but from the looks on their faces I think they enjoyed it.
