Migratory birds are declining globally because of the way that humans have modified the landscape over recent decades – according to new research.
The new study reveals that population declines have been greatest among species that migrate to areas with more human infrastructure – roads, buildings, power lines, wind turbines – as well as higher population densities and hunting levels.
Habitat degradation and climate change have also played a part in driving long-term declines.
The research team hope their work will help inform how best to target conservation efforts. James Gilroy, from UEA’s School of Environmental Sciences, said: “We know that migratory birds are in greater decline than non-migratory species, but it’s not clear why.
“We wanted to find out where in their life cycles these migratory species are most exposed to human impacts.”
The team identified 16 human-induced threats to migratory birds, including infrastructure associated with bird disturbance and collisions, conversion of land from natural habitat to human land use, and climate change. Advances in satellite imagery allowed the team to map each of the 16 threats across Europe, Africa and Western Asia. The team also created the first ever large-scale map of hunting pressure across the region.
A total of 103 species of migrating birds were studied, including many rapidly declining species like turtle dove and the common cuckoo, using large-scale datasets.
The team calculated “threat scores” for factors such as habitat loss and climate change, across breeding locations, as well as non-breeding ranges. They then explored the relationships between these threat scores and bird population trends calculated from 1985 to 2018 by the Pan-European Common Bird Monitoring Scheme (PECBMS).
Claire Buchan from UEA, said: “One of the biggest impacts seems to be caused by things that would kill a bird outright – for example flying into a wind turbine, a building, being electrocuted on a powerline, hit by a vehicle or hunted. We found that exposure to these human-induced ‘direct mortality’ threats in the bird’s wintering ranges are reflected in population decreases in breeding birds.”
Aldina Franco, also from UEA, said: “Our findings are important because we need to understand where declining species are being most impacted by humans across their seasonal migrations. Pinpointing where birds are most exposed to these threats could help us target conservation actions.”

Jersey Island’s striking landscape shares many similarities with the Llŷn Peninsula in northwest Wales and the Iveragh Peninsula in southwest Ireland. Each of these regions are popular tourist destinations that are heavily influenced by agriculture and their connection to the sea. Their coastal landscapes are also extremely important to many forms of wildlife, not least our favourite corvid, the red-billed chough. The choughs’ iconic call, coupled with their bright red beaks and legs are a staple of the Llŷn and Iveragh Peninsulas. And these birds are clearly held in high regard on Jersey since their reintroduction in 2013.
On the Llŷn and Iveragh Peninsulas, choughs nest within mines, quarries, farm buildings and along cliff faces. A short distance from these nest sites, choughs have access to a mix of foraging habitats such as beach, sand dune, earth banks, coastal and agricultural grasslands, coastal heath and some well-grazed upland sites. Here, choughs can find their favourite food items such as beetles, ants and spiders, as well as the larvae of beetles, butterflies and moths. The importance of Llŷn and Iveragh for choughs is one of the primary reasons why ‘Special Protection Areas’ (SPAs) have been designated on both peninsulas.
The most recent national chough censuses indicated that chough populations across the UK and Ireland are relatively stable, although there were some concerning declines in certain regions. These national surveys are usually conducted every ten years in the UK. However, there was nearly two decades of a gap between Ireland’s 2002/03 national chough census and the most recent census carried out in 2021. Although these censuses provide invaluable insights into the health of national and regional chough populations, more frequent updates would help us determine how our choughs are faring in the years between censuses.With this in mind, the University College Cork-led LIVE Project, in collaboration with the National Trust in Wales and the Royal Society for the Protection of Birds (RSPB) organised a cross-border ‘Chough Count’ on the Iveragh Peninsula in southwest Ireland and the Llŷn Peninsula in northwest Wales on 12th March 2022. This initiative typifies one of LIVE’s main objectives – the sharing of knowledge and best practice between our two peninsulas.
The Llŷn Peninsula’s second ‘Chough Count’ saw 51 volunteers record 254 choughs as the sun shone in north Wales. Iveragh’s inaugural count saw twenty-six volunteers record 64 choughs in quite challenging weather conditions. By conducting annual counts of Llŷn & Iveragh’s choughs, we can detect trends in these populations in the years between censuses and we can identify important habitats for this protected species. The 2022 chough count also gave our surveyors the opportunity to record some of our other native birds such as skylarks, fulmars, white-tailed sea eagles and a hen harrier in Iveragh, as well as red kites, peregrine falcons and a green woodpecker on Pen Llŷn.
Distribution of records during Pen Llŷn’s second ‘Chough Count’ held on 12th March 2022.
The LIVE Project (ecomuseumlive.eu) has received funding from the European Regional Development Fund through its Ireland Wales cooperation programme. Led by the School of Biological, Earth and Environmental Sciences in University College Cork, LIVE works to enable the coastal communities of Llŷn and Iveragh to promote their natural and cultural assets, with the aim of encouraging more sustainable tourism opportunities in these rural regions of Ireland and Wales.
The sun has set on the Red-billed Chough Project officer’s time here in Jersey with Birds On The Edge and with Durrell. Her absence from Jersey Zoo Bird Department and at the Sorel aviary is undeniable. We can only strive to be as dedicated to the Jersey free-flying choughs as she once was. But despite this saddening farewell; the chough show must go on! Updates on the choughs will continue; and what an exciting month it has been!
Native reptile sightings
While the Island’s starting to heat up with all this fantastic summery weather; there have been many green lizard sightings. Jersey is the only place in the British Isles where green lizards occur naturally and are one of the three species of lizards which are protected under the Conservation Wildlife (Jersey) Law 2021. Green lizards can be seen between spring and summer. Green lizards are sexually dimorphic; meaning, they encompass differences in appearance, shape and/or size between the sexes, they are easily distinguishable: the male green lizard (as seen in the image) is bright green with a bright blue throat but is also larger than the female. In contrast, the female lizard is smaller, less vibrant and has creamy and/or brown lines running down the body. So, now that we’re in May, it is the perfect time to keep your eyes peeled when walking in and around any of the Island’s coastal paths. If you happen to spot a green lizard or the other lizards native to Jersey; Jersey Amphibian and Reptile Group (JARG) and Jersey Biodiversity Centre (JBC) would love to know, so make sure you send your sighting details to them as it will help with the protection and monitoring of the reptile species on the Island.
If reptiles aren’t your ‘cup of tea’ then not to worry, the summer also brings out our beautiful butterflies. Between the months of April and September you’ll find butterflies are very abundant across the whole of the countryside. We’ve already come across some dedicated volunteers conducting butterfly surveys for Jersey Butterfly Monitoring Scheme (JBMS) along the coastal path from Sorel Point carpark. Butterflies are used as great environmental indicators; this is because they live in specific habitats and can indicate the general health of the land by their presence or absence. As Butterflies are generally a widely abundant terrestrial insect that are often admired for their large size and distinct appearances; they are the ideal insect for surveying. In and around Sorel we’ve seen butterflies such as: speckled wood, small heath and small copper. All three of these butterflies’ ideal habitat is semi-natural heaths and agricultural environments; indicating that the area around the Sorel aviary is relatively adequate land for foraging habitat for our red-billed choughs.
Moulting time for non-breeders
But, enough about the Island’s non-chough native wildlife, what about the birds themselves?! It’s that time of year again when the non-breeding choughs start to moult – this is becoming readily apparent by all the feathers we can now collect from the Sorel aviary and by the less than perfect looking feathering on some of the non-breeding choughs. Choughs generally start their moult between May and/or early June. They start moulting their central tail feathers first working outwards. They then start moulting and growing their wing feathers, the primaries, around the same time as their tail; but complete their tail moult first. The moulting process for an adult chough can take up to 152 days.Monday, 9th May
On 9th May, Jersey celebrates Liberation Day and Jersey puts on quite a show with flags at many houses and businesses as well a spectacular parade. But Jersey Zoo had another cause of celebration, the bird flu restrictions were finally dropped by the Government. Therefore, Jersey Zoo was given the green light to move any of birds temporarily sheltered back out into their original enclosures; enabling the public to enjoy some missing birds from the collection. It was good to see all the Chilean flamingos and red-breasted geese back in their valley. But this brought the chough project good news too; as it meant the arranged Ronez Quarry visit could go forward and this year’s hatched chicks could potentially be ringed!
Ronez Quarry visit
Jerseys free-flying choughs have had another productive nesting season. There are eleven breeding pairs in the group this year and with help from Ronez Quarry we discovered twelve nests in the quarry buildings. Unfortunately, from the twelve nests there were only hungry chick vocalizations from seven out of the twelve nests. But worry not! Some of the other breeding pairs have settled in other locations around Jersey. These seven nests are owned by the known breeding pairs that have been presumed incubating (absentees at supplementary feeds can be a give-away). Choughs are well-known for being faithful when it comes to their nest sites; but it’s always worth a check of the new nests. None of the new nests found by quarry personnel this year were being used by our breeding pairs. This could indicate that some of the younger choughs are practicing for when they start nesting in the near future! Once the incubation period is over, the female will still spend the majority of her time on the nest but as the chicks get older and/or gain vital feathering she spends less time sat on the nest; allowing us to see both the female and male take alternate feeding trips to the aviary. A good indication that the chough chicks will be of good size is the appearance of the female within the breeding pair also leaving the nest to forage, or in our case, visit the aviary for the supplementary feed. As we’ve been seeing both sexes of each breeding pair of late and have estimated all the breeding pairs’ end of incubation dates, we knew that most would have chicks old enough to ring around the end of May.
With help of loaned equipment provided by 4Hire, Ronez’s Assistant Operations Manager, Toby and Durrell Chough Intern, Charlotte were able to reach great heights and see into five of the seven nests in the quarry. Two of these nests were inaccessible due to high winds and/or the position of nests in buildings. But worry not, when visiting the quarry, we could clearly hear hungry chicks from all seven active nests!
The first nest we checked was Lee & Caûvette’s. They had three chicks, no older than nine days old! This meant they were not old enough to be ringed, but at least we knew that this breeding pair has been successful in hatching three chicks this year. The second nest we visited was Trevor & Noirmont’s which only had one chick inside, but it was old enough to be removed from the nest to be health-checked and become the first chick to be given temporary rings this year. This chick was ringed with this year’s ringing colour; dark green and will be identified as ‘white over dark green’ and/or Manitou (named after the cherry-picker which gave us access to the nest).
Our third nest site to visit was going to be Percy & Icho’s nest; however, high winds picked up and both the quarry staff and Durrell staff knew it was going to be too dangerous for us and the chicks to attempt to visit their nest box. It was clear though that the breeding pair were visiting this nest and there were definite sounds of hungry chicks coming from inside; the big question will be how many will we greet around their fledging date! The fourth nest we looked at was Kevin & Wally’s. We had previously been sent a photo of this nest from Toby – in this picture, we thought there were only two chicks but while at the quarry we got a lovely surprise from the video we took of inside the nest. There were definitely three of the oldest chicks we’d seen in a nest around the quarry so far! Due to the nest being out of sight; we did not attempt to ring these chicks for their own safety – but we hope to see them all at the start of June at Sorel aviary!
The fifth nest visited, that of Green & Pyrrho, was accessed with the stair lift; they had three chicks which were also old enough to ring. However, again, due to the positioning of the nest and the supporting beams of the building, we could not get up high enough to reach into their nest box – and again, the chicks were left alone. The sixth nest visited was Bo & Flieur’s, in a very noisy and dusty building; surprising how the adults and/or chicks survive inside it! There was no way of accessing this nest but we could hear some very noisy chicks indicating their reproductive success. We may not know how many chicks are in this nest; but we know to expect some to arrive in the coming month. The seventh and final nest we visited was Dusty & Chickay’s. They have four hungry chicks in their nest but because of their placement in the building, this nest was inaccessible to cherry-pickers and stair lift equipment. It’s almost as if the choughs build their nests so that no one can access them!As much as our visit didn’t go completely to plan, thanks to mother nature and the breeding pairs’ chicks’ ability to latch onto their nests making us unable to remove them to ring them before they fledge’ it’s clear that this year our choughs have been very productive; most if not all have had three or more chicks. We currently know of 14 chicks in the quarry; but let’s not forget that we still have an unknown number of chicks from two other breeding pairs! Going from our breeding population’s clutch sizes in the past (our choughs usually lay up to four eggs), there could be at least three or four chicks in each of the other two nests that were inaccessible. Which could bring this year’s hatched chick count to 22!! This may be wishful thinking, but it’s always good to expect the unexpected!
For a second year in a row the chough pair at Plémont have successfully hatched three chicks. We discovered the happy news at the end of the month. Using a very, very, very, long lens we were able to get photos of the chicks’ heads whilst begging for food.
It is hard to give a precise age without seeing the rest of their body, but best guess is a week-old give or take a day. This would also match up with nest observations we made over April; our estimated hatch date was the 22nd. Returning the following week further confirmed our age estimate as their little heads were still relatively bald.
Both Plémont parents are now out and about in search of food for their young. Concerns were raised when we started seeing both parents at the Sorel supplemental feed desperate for food. Choughs nesting at Plémont do not normally return to Sorel until their chicks fledge or the nest fails. This was the first time in five years. Chough chicks devour a lot of insects whilst in the nest, so chough parents tend to forage close-by to conserve their energy.

There has been a big increase in footfall at Plémont this month which could deter the choughs from foraging close-by. It has also been relatively dry so the soils around Plémont are not as favourable to soil-dwelling invertebrates. There are many other reasons why the parents might be visiting Sorel, the good news is that the chicks are still alive and begging well.
All being well the chicks should fledge at the end of May, start of June. We will be monitoring more closely this year around the fledging period. Last year we knew that two of the three chicks fledged, but don’t know what happened to the third. Then one disappeared within the first week of being out. If that happens again this year, it would be good to try and understand why.
Potential success at Ronez once again
We believe at least five of the eight nests in the quarry have chicks. This is based on behaviour of the pairs at the feeds and in the quarry. The females had been suspiciously absent. Then when they did turn up, they were very noisy. Pyrrho and Icho in particular would fly in vocalising, then follow their partner like a noisy shadow demanding food and being fed instantly. It’s quite an interesting sound they make trying to beg and swallow the food at the same time!

At the end of the month, we were then seeing the male and female in a pair making repeat trips between aviary and nest site. This tends to be when they are feeding chicks although we have no definitive proof yet. We are trying to arrange a quarry visit for May.
Our Jersey Zoo pair also had success this month with their first chick hatching on the 28th followed by number two the next day and number three shortly after.
Nest cam footage showed the moment the first chick hatched whilst mum looked on. Photo credit Durrell.
There was a fourth egg…spoiler alert…it failed to hatch. The nest camera shows the parents still holding out hope until May 2nd. Mum took the executive decision to remove the egg from the nest around lunchtime. You can see this in the video below around 40 seconds in.
We may send the chicks over to the UK shortly after they fledge so they can become part of the release project in Kent. This is very much dependent on the Jersey and UK Government’s rulings over exports and imports of birds from a bird flu protection zone. Restrictions for indoor housing of poultry will be lifted in Jersey on May 9th.
No success in the new territories
The Trinity pair appear to have abandoned their nest and are spending more time at Sorel. They still visit the stables but the nest is now being used by doves. We had hoped that the choughs had found a more favourable site in the Parish yet their casual behaviour at the aviary suggests they’ve given up.
An article will be published in the summer edition of the Trinity Tattler magazine asking residents to report any sightings. This might shed some retrospective light on the situation. I’m not holding out hope that there will be a surprise nest discovered.
In similar circumstances, we are now seeing the ‘Corbière pair’ back at Sorel. Their suspected nest was last seen being used by pigeons. We are used to seeing choughs fail at establishing territories in the south west. Food supply, or lack thereof, may play a role in this. The cliff tops are choked with invasive sour fig (or Hottentot fig) (Carpobrotus edulis) and the exposed ground isn’t very accommodating to soil invertebrates.
Cliffs around Corbière could offer potential nest sites for choughs. Photo by Liz Corry.

Return visit to Guernsey
We have seen another report of chough posted on the Guernsey Birdwatching Facebook group. Dated 16th April, it is clear that the bird is one of ours from the red and white striped ring, but that is all we know unfortunately. They were foraging at Pleinmont again. Clearly a popular site.

It just so happens that Portelet and Archirondel were missing from the Sorel feed that day. Coincidence? This is very exciting news if they have made a second round trip between islands to forage.

Boring but necessary aviary stuff. April has brought sea fog, hail, downpours of rain, but mainly sunny days perfect for grass growing which means we do lots of grass mowing; weekly almost daily depending on how much time we have spare and how long the strimmer battery lasts.
Keeping the grass short inside the aviary has multiple benefits. Photo by Liz Corry.
The holes in the netting we had repaired earlier in the year have reopened with extra wear and tear. Nothing to do with rodents just weathering and strain on the netting. We need to get the henchman ladder back up to Sorel to carry out the repairs.
We have replaced a couple of rotting hatches, rusted door bolts, replaced food stands and repaired benches for accessing hatches.
Holes have reappeared in the netting along the central pole. Photo by Liz Corry.

This will be my last chough report for Birds On The Edge and Durrell. I’ve been with Durrell for eighteen years and worked with the choughs since they arrived in the Zoo in 2010. It was a hard decision to make as I’m leaving both my job and the island I’ve called home for the last sixteen years.
I’m not quite leaving the choughs though as I will be taking up a new role as chough release supervisor in Kent for The Wildwood Trust. No doubt I will keep popping up from time to time on Birds On The Edge or at the Inter-Island Environment meetings. Like Where’s Wally minus the red and white striped top.
I’m extremely proud of what the team has achieved over the years, and I often forget letting the day to day stresses of running the project take over. Plémont is the perfect place to remind me. When I first visited the bay in 2006, I didn’t know the Channel Islands were once home to choughs. Eight years later I remember visiting Plémont café with friends and musing over the idea of one day seeing the then recently released choughs utilise the cliff tops and caves. And now, well why don’t you find out for yourself. Head to the café (I recommend the waffles), sit outside, soak up the rays, and listen…

Channel Island Choughs
The dream finally became a reality this month when two Jersey choughs were photographed in Guernsey. We first discovered the birds had left the island through a post on social media. A post on Guernsey Birdwatching’s Facebook page showed a selection of images and video from a very excited birdwatcher. The images clearly showed the leg rings enabling us to identify Archirondel and Portelet as the two tourists. These are two young, non-breeding females and as such have the freedom to explore.
The last time we recorded Archie and Portelet at the supplemental feed was on 22nd March. After some frantic armchair detective work we discovered that they visited Sark too on 23rd March and were then next seen on the 25th in Guernsey.
The report from Sark is a wonderful description of what it’s like when you spot a chough in flight for the first time:
“I went out to do the mowing at 3.30 pm and thought I heard a jackdaw which we do not usually see in Sark. I looked up and saw a black bird disappearing over towards Derrible Bay (fingers on wings were visible) but it was only a fleeting sighting. A bit later at 4.45 pm when I had finished the mowing I heard the call again and two choughs flew right above me and I realised that it wasn’t a jackdaw but a chough’s call. The red bill of one could be clearly seen but because of the shaded light I could not see whether rings were present on the legs. An altogether more slender bird than the crow and smaller. They turned right and flew down the meadow as if heading off east towards the harbour in a tumbling flight and then veered abruptly and flew off towards the north but heading back towards the east coast.”

The pair stayed in Guernsey over the weekend foraging around Pleinmont near Portelet Bay! Portelet, the chough, returned to Jersey along with Archirondel on Monday the 28th. Quite literally a girls weekend away in the Bailiwick of Guernsey.
Image from Google Earth.
We envisaged this could happen when we first planned the reintroduction. It’s not unheard of for UK choughs to spend time foraging on both mainland and a nearby offshore island. This trip might have been a one off, equally it could be the start of a new foraging pattern for Jersey’s choughs.
There is certainly suitable foraging habitat on offer in Guernsey. Pleinmont looks very similar to Les Landes and Grosnez in many respects, but it is too soon to talk breeding opportunities. We need more males for that to happen. No pressure on the breeding pairs then!

The 2022 breeding season is underway
March madness came into full force when the breeding choughs began nest building, or nest refreshing for the experienced pairs. Ex-volunteer, Neil Singleton and his wife Ali were treated to an impressive display of ‘flying wool’ when they visited Sorel towards the end of the month. Timed well with the return of the sheep.

I suspect these birds were heading to the quarry although the Plémont pair could have been involved too. They tend to stay local and collect horse hair or wool for Grosnez to Grève de Lecq. It might look like easy cargo, but I have seen a fair few accidentally drop their wool between Sorel and the quarry. Usually when they get distracted by a peregrine or gull or keeper walking below carrying insects!
Blurry but the intentions are clear. Photo by Neil Singleton.
Plémont sea crows return
Minty and Rey have returned to Plémont to refresh last year’s nest before Rey begins egg laying. The sea crows (to use an old Greek nickname) can often be heard foraging around Plémont headland and seen flying to and fro in search of food. During the nesting season, French choughs are known to spend most of their time within 300 metres of the nest site. If the habitat is suitable, i.e. lots of soil and/or dung invertebrates, the chough pair will be successful.
Minty can afford to spend some time chilling out right now. Once Rey starts incubating, he has the responsibility of finding food for the both of them. Maybe that is why he was happy to do a bit of sunbathing down at Plémont.

The Troublesome Trinity Two
Pinel has returned to Trinity taking his new female, Vicq, with him. They have been visiting the same places as last year such as Peacock Farm and East Ridings Stables. They appear to have chosen to nest in the same building he used the year before with his previous partner. Maybe he sees the potential in the property to become a family home?
Last year the pair abandoned early and weeks later the female disappeared. Hopefully he will have more success this time with Vicq who hatched three chicks in 2021. Sadly, the chicks died before fledging but it shows she can do it.
We are working with the property owner to monitor the situation and see if we need to assist in any way. The owner is very wildlife-friendly which is a big bonus and we have set up a camera-trap in the building, swapping out memory cards on a weekly basis.
Playing in the sand pits
Another chough pair we are keeping an eye on are Danny and Jaune. We had reports of choughs in Simon Sand and Gravel Ltd. down on the west coast. Choughs have also been seen around Corbière this month so the assumption is that they are looking for a suitable nest site but since they are still sub-adults it is doubtful that they will breed this year.
We are delighted to be running this training session in person again and to be joined by Dr Robert Ward, Data and GIS Officer, Amphibian and Reptile Conservation who will be presenting at this event. Rob studied our local grass snakes for his PhD. He is extremely knowledgeable on Jersey reptiles and how to get the best chance of seeing reptiles locally.
What is Reptilewatch JE?
Reptilewatch JE is the successor to the National Amphibian and Reptile Recording Scheme (NARRS) which ran in Jersey from 2007 to 2018. During this time volunteers provided a great deal of information which has been used to inform the design of Reptilewatch as well as influence efforts to protect the species.
Reptilewatch JE is a project that aims to gather sightings of Jersey’s reptiles to help assess their conservation status, distribution and habitat requirements.
By taking part in the Reptilewatch scheme, you will be contributing important data to inform the ongoing conservation of these incredible creatures and helping inform future policies.
How can you help? There are opportunities for everyone to get involved. Depending on your interest, available time and experience you can currently get involved in two ways. • Level 1 – spend 30 minutes looking for reptiles No experience or training is required. • Level 2 Wall lizard – carry out six visual surveys, each taking 30 minutes No previous experience needed but attendance at this training session is required.
Schedule of the day (provisional): • Welcome and Introduction • Reptile Identification – how to identify reptiles and some of the other animals you might encounter • How to get involved Level 1 and how to record your findings • How to get involved Level 2 -Wall Lizard and how to record your findings • Field Session • Opportunity to sign up and network with other volunteers.
Please don’t forget to wear appropriate clothing and footwear for the field session.
If we are lucky enough to have good weather on the day, please bring a hat and appropriate sun protection and some drinking water. Also, if you have any close focusing binoculars, please bring these with you.
Please take a COVID lateral flow test before attending. Please don’t attend if you feel unwell or have a positive COVID test result.
The Arrival of the Puffins is a unique festival that highlights the plight of these wonderful birds and the key role Jersey has to play in in order to protect and save the puffins and other seabirds.
Join us to celebrate the arrival of the puffins of Jersey back to their breeding cliffs, as well as the arrival of the willow puffins to the National Trust grounds at Plémont.
There are a series of activities as well us the unveiling of the magnificent puffin – willow sculptures that have been created to highlight these challenges. This event is open to everyone so please come along and join us!
You can drop by anytime between 11am and 1pm and you will find opportunities to watch puffins and other seabirds (if they are about!), walks of the Seabird Trail, and live music to celebrate the puffins and other sea folk.
Programme: – Between 11am and 1pm: Puffin Watch at the Stone Circle – with Alli and Neil from Birding Tours Jersey. Just drop by, scopes and binoculars will be provided. – At 11h and at 12h: Live music next to the willow puffins, with Aureole Choir and local folk band Sonneux. Be ready to sing along, lyrics will be provided! – At 11.30h and 12.30h: Seabird Trail taster walks with local birding expert and photographer Romano da Costa. Bring your binoculars and cameras if you have them.
See you at Plémont on Sunday, and hopefully the real puffins will be there too!
Sculptures built in partnership with Geomarine. Event kindly supported by JDC (Jersey Development Company).
Jersey’s annual Great Garden Bird Watch returned some interesting results this year. Held on 5th and 6th February, Islanders were asked to spend an hour in their garden and list all the birds they could see.
For the first time in its twenty-one year history, choughs were recorded. Not only that, they were spotted on a bird feeder filled with peanuts, sunflower hearts, maize, pinhead oatmeal and millet.

After digging a little deeper, we discovered that some of the choughs have been visiting this garden since 2020. The photos submitted identified breeding pair Trevor and Noirmont, prior to that, we know a young female has also visited with the pair.
Whilst surprising, it is not unheard of for wild choughs to use bird feeders. There are a few of reports from Cornwall and Wales of chough opportunistically feeding from garden bird feeders. In each case including Jersey, the gardens are not your typical urban estate fenced-in garden. Trevor and Noir have been visiting property at Grantez which surrounded by grazed land (sheep, horses, and donkeys). From Grantez’s vantage point, you can see the entire west coast from L’Étacq to Corbière, both areas favoured by choughs.

The interesting information from this report is the type of food they are eating. Pinhead oatmeal forms part of the supplementary diet provided to Scottish choughs in Islay. Its not considered as typical wild chough diet, but does suggests there is something in the mix that the birds are looking for. We are hoping to carry out research into diet preferences in the near future. This exciting discovery is certainly food for thought.
Foraging further afield
As mentioned above, the choughs have been visiting Grantez. In addition to the garden report, the National Trust Rangers have seen choughs foraging near the dolmen on Grantez headland.
Choughs are also visiting Corbière, Les Mielles dunes, and potentially back at Crabbé where a pair roosted in 2020. The gun range, sheep-grazing, and now goat-grazing, provide great habitat for choughs to find food. Farm structures and cliff faces offer ample nesting opportunity for a pair looking to setup a new territory.

We are also keeping our eyes peeled around Trinity again. There is a good chance Pinel might try to set up a territory again this time with his new female. The roost site used in 2021 is surrounded by horse paddocks which provide foraging opportunities and nesting material – choughs sometimes use horse hair!

Catch-ups with the choughs
We finally managed to trap the elusive Bo and Flieur in the aviary to replace their leg rings. I say elusive, but I could equally use stubborn/clever/annoying/uncooperative… This is the pair who always fly to the aviary with the others yet refuse to go inside when they know we are trying to catch choughs. Bo in particular keeps both eyes firmly fixed on staff. Flieur might break once in a while and tempt fate, but flees at the first inclination that the hatches might be about to close.
I struck lucky on Monday 7th when all thirty choughs turned up for the feed all showing signs they were hungry. Typically had to be the day I was working alone although maybe that is why Bo’s guard was down.
I replaced Bo’s missing plastic ring and swapped Flieur’s faded pale grey for something more obvious. It felt wrong. No one likes change. Flieur has been grey since she arrived at Sorel. Grey is her identity.
It’s also a really stupid colour to use in the wild in a climate where grey skies prevail. So out with the grey in with the mauve.

Storm damage at Sorel
The Island has seen its fair share of storms this year. February’s Storm Eunice and Franklin delivering devilishly strong winds (55-63 mph or 89-102 km/h). Yet somehow the aviary miraculously remains standing.

The winds did create new rips in the netting and annoyingly re-opened ones we had sealed last month. Another trip to Sorel with the Henchmen ladder is in the pipeline. We have budgeted for new netting to be fitted later in the year. Hopefully the current net will hold out until then.
What didn’t remain standing was the Birds On The Edge sign at Sorel car park. Cue a phone call on my morning off followed by a spot of coastal ‘carpentry’. I couldn’t unscrew the sign from the posts to fit it in the car so the logical solution…saw off the posts! In my defence, they were rotten at the base, and we reused the wood at the aviary. The sign and fencing will be replaced by the Countryside Rangers in the near future.
It was like that when I got there your honour! Photo by Liz Corry.
Grazing returns to Sorel
Very pleased to see the return of the Manx loaghtans to Sorel this month. Perfect timing for the choughs who will soon need wool to line their nests.

It also means we should hopefully see the return of dung invertebrates (aka chough food) who depend on the sheep faeces. Not sure which made me more excited, the choughs foraging in amongst the sheep or the return of mating dung flies. If you haven’t already, please checkout our article about Dung Beetles for Farmers.

Avian influenzas confirmed in Jersey
Two wild buzzards have tested positive for avian influenza: the first confirmed cases in Jersey. This was followed shortly by the death of a red-breasted goose in the Zoo who also tested positive for the strain H5N1.
Choughs are considered to be at low risk of infection, and we do not foresee any major changes in how we manage the supplementary feeds. To reduce the chance of transmission between field sites and the Zoo, we have set up a disinfectant foot bath at the aviary with dedicated footwear. We continue to maintain high hygiene standards at the aviary and have separate footwear for in the Zoo and out in the field.
We will of course monitor the situation and consult with the States Vet if any changes occur.
Task Perhaps best known for its exotic plantings, the gardens on the Promenade at Gorey have one patch of grass desperate for a pollinator friendly make over.
