Birds On The Edge is delighted to announce that Jersey’s Atlantic puffins have started to arrive to their breeding cliffs on the Island’s north coast.
This small colony has comprised only four breeding pairs in the last few years, and it is hoped that at least as many will return this year. The puffins have been a bit late to arrive, with only one or two having seen so far over the past few days.
This is the most delicate time for our puffins, as they settle back in their nests and wait for their mates to arrive. Any disturbance or negative experience could put them off and make them abandon the area, sending them off to look for quieter breeding grounds elsewhere. After they have settled, the presence of boats and other watercraft near their breeding sites might disrupt or affect natural behaviours, such as incubation of the egg, fishing, or feeding their chick.
Birds On The Edge asks everyone to follow the guidelines of the Seabird Protection Zone (SPZ) between Plémont and Grève de Lecq, and avoid visiting this area by boat, kayak, paddle board or any other type of watercraft between March and July. These guidelines are already observed by boat and kayak tour operators, who avoid this area at this sensitive time, as well as by the local fishermen, who only visit the area briefly to check their pots.
The presence of watercraft in the Seabird Protection Zone is monitored during regular puffin and seabird surveys. In 2020 a steep increase of leisure craft in the SPZ was noticed in comparison with the previous year. The number of private boats and kayaks recorded per hour increased by 360%. This was believed to be a result of the travel and lockdown restrictions put in place during the pandemic. It was hoped that this year all private boat and kayak users will avoid the area completely until the breeding season is over. However, Birds On The Edge has already received reports of people on kayaks going through the SPZ over the past week.
It is worth remembering that puffins and their relatives, the razorbills, can be found all across the north coast, but as their breeding is restricted to this area, it is extremely important to give them peace and quiet in order for them to return to their nests.
The safest way to enjoy puffins is from the public footpath between Plémont and Grève de Lecq. As the Jersey puffins nest in rock crevices and between boulders below the coastal slopes, they are out of sight when in their nests. However, they spend a lot of time sitting on the water below the cliffs, and the safest way to watch them, for both puffins and people, is from the footpath between Plémont and Grève de Lecq, looking down to the water. The various vantage points, benches and bunkers along the footpath are good spots to watch puffins and other seabirds from.
The public is also invited to join one of the free ‘Puffin Watches’ that will take place at Plémont over the Easter holiday break. For further details please consult the Facebook pages of Jersey Birding Tours and Jersey Wildlife.

Ahead of the Island census next month we have taken account of Jersey’s chough numbers. We are missing several birds from the Sorel feeds. It is becoming increasingly harder to conclude that a chough missing at the feed means a dead chough. The chough in France is testament to that! However, the chances of them being alive are very slim if we don’t have any sightings elsewhere, there has been a long and consistent absence from Sorel, and/or their partner has re-paired.
With that said we have nine birds who have become ‘missing presumed dead’ over the last six months. This potentially brings the Jersey population down to 34 from 43 and one female in France.

I have managed to carry out one catch-up to replace missing rings. We now have a few more birds with missing or broken rings. This adds to the confusion of who is present or not.
The situation at Plémont has been a bit of a mystery. Beaker has still not been seen despite the female, Beanie Baby, regularly showing up for supplemental feeds. Only one chough was seen at Plémont. Then towards the end of the month, two choughs were flying around. This coincided with Beanie Baby preening and foraging with a new male at Sorel!
We need to confirm which birds are at Plémont. Gut feeling says Beaker is no more, Beanie has found a new partner, and is having another go nesting at Plémont.

Another curve ball…the female hanging out at Corbière has not been seen in a long time. Her partner, Minty, has been at Sorel every afternoon for the feed. Here is the ‘fun fact’, Minty is now paired with Beanie Baby.
Choughs have been visiting the Zoo again. One in particular. In fact, of all the times we have been able to identify leg rings, it has been Bee or Bee with Pinel a young male. She visited the Zoo last year when she was paired with a different male, Mac. Whilst never confirmed, we assumed Bee and Mac were the pair regularly spotted around Trinity and St Martin.
Bee renewed her membership to the Zoo so she could visit the chough aviary. Photo by Liz Corry.
Mac has been missing for a while. Bee might be visiting the chough aviary in the Zoo looking for a new partner. There are still three single males in with the breeding pair. She might simply be looking for free food whilst away from Sorel. She has been observing the keepers and now tends to arrive shortly before a feed is due then disappear until the next feed. The Zoo choughs get three feeds a day.

Breeding pairs for 2021
We have ten pairs going into the 2021 breeding season. We only have twelve males in the flock, two of which are only one year of age, so ten is good going. Half the pairings are proven, having produced one or more broods in the past.
Hopes for a Trinity nesting pair now seem very slim. Plémont still has promise although unintentional public disturbance could be an issue if the 2020 nest site is used. As always Ronez Quarry will be the stronghold and the focus of our monitoring.
Observations at the supplemental feeds suggest the nest building or, for some, nest-refurbishment started this month. We think at least one female has started egg laying. Could we have Easter chough chicks?
Cappy in Carteret
Cappy is still alive in Carteret and starting to gain followers in France.

Keepers managed to catch-up the three boys from the display aviary in the zoo and move them to an off-show holding area. This allows Tristan and Penny to start breeding without territorial disputes.

All three males looked healthy and were implanted with transponders for ID. All of the captive-bred birds have them. They will be exported to Paradise Park when travel permits.

Whilst travel doesn’t permit…
I have attended several online planning meetings over the past few month regarding proposed chough work in the UK. I tend not to mention them as they are quite heavy going, tedious things…
Peregrine falcon, a highly skilled predator of flying birds and famous speed star of the skies is one of the most widespread birds on the planet. It sadly became threatened with extinction across most of its range as its numbers plummeted in the 20th century through persecution and the residual effects of organochlorine pesticides. Breeding on each of the main Channel Islands, peregrines became locally extinct in the 1950s.
We are now, however, in more enlightened times. Surely. With persecution outlawed and pesticides like aldrin, dieldrin and DDT banned, the highly adaptable peregrine began to stage a remarkable comeback. Seemingly again a regular sight on every cliff and city cathedral in the UK, the falcon returned too to our islands. After a pair bred in Sark in 1994, the other islands were recolonised, and the first chicks hatched in Jersey after 42 years in 2000. Quickly the wandering bandit (peregrine comes from the word peregrinate, to wander, and it does have wonderful mask) was back and old eyries were reoccupied. Jersey now hosts several pairs with equal numbers across the other islands. We don’t have a cathedral, so they have to make do with St Thomas’ Church although they may not be there every year as all of our pairs regularly move nest sites within their territories.
Poisoned in Guernsey
Now it seems that everyone’s favourite bird of prey (well, it is popularly considered as the ‘fastest animal on earth’) is not quite as safe as we thought. Last year several peregrines, and a buzzard, were found poisoned in Guernsey. Had DDT returned? No, these birds had apparently been directly poisoned, killed, not accidentally, but because they were, well, peregrines. Who would do this? Actually, peregrines have not really been everyone’s favourite bird. People who keep pigeons in particular often don’t like them. Yes, our peregrines do hunt and kill pigeons and although there are lots of wild pigeons on the cliffs and in the town where they live, it is the hunting of owned, racing pigeons that draws ire in certain quarters.
Jamie Hooper sums it up ‘I am saddened that some of our native bird species are still at risk of being killed illegally by a misguided minority. Although birds of prey have slowly recovered from historical persecution, this process of re-colonisation has been significantly impeded by those who wrongly think that raptors should be removed from our natural environment. The scale of the recent killings of peregrines in Guernsey has been particularly devastating to the small local population and we remain keen to eliminate such criminal activity from our island.’
We don’t actually know who poisoned Guernsey’s falcons, despite an offer of a reward, but, as it seems deliberate, the list of suspects can be considered fairly short. That people would deliberately kill a wild bird that only hunts to eat and feed its young when high losses are tolerated among amongst pigeons that get lost, die in storms or simply decide that living wild is much more fun (an estimated 86% of the racing pigeons lost each year fail to return for reasons other than predation by birds of prey) should rule this group out. Of course, it should.
Shot in Jersey
In Jersey, people are sometimes quick to criticise their neighbours so the news that here we had a two-year old, ringed, peregrine shot will come as a shock, I hope. In 2020 a ‘feisty’ but poorly falcon was picked up in December near Ouaisné and died in care at the JSPCA. Examination by Senior Veterinary Surgeon Jo McAllister showed lead shot on X-ray, not enough to kill it outright but enough to prevent it hunting, letting it starve to death instead. Again, we don’t know who shot it but shot it was, and it may have been mistaken for some other bird. A pigeon again? It does show that peregrines are still at risk from people who may not like them and have unilaterally decided to return them to that late 20th century level of threat.
In the way of aircraft
Peregrines often seek out their prey by circling high in the sky, above their flying dinners down below. Any good, rising, air current helps them keep airborne and in ‘station’ without them wasting energy. Has using winds blowing up the escarpment along St Ouen’s Bay, been the reason that several have been hit and killed by aircraft as they approach or leave Jersey’s airfield? At least six have been found dead or dying in recent years, most or all juveniles. Juvenile peregrines are, while they are young, larger than adults as they have a lot to learn before they can master the skies like their parents and slowly moult in shorter feathers and keep out of the way of aircraft. While very unfortunate, at least these deaths were accidental, and the bodies have gone for research at the National Museum of Scotland.
The 20th Jersey Great Garden Bird Watch will be held over the weekend of 6th and 7th February
20 years? Yes, the annual Action for Wildlife Jersey and Birds On The Edge garden bird count has reached this significant milestone. Although, it won’t have been undertaken in circumstances quite like these before! Last year, little did we know what was coming. The count has a long tradition of seeming to encourage bad weather so our fear was of the Pest From the West. Did it happen? Does anyone remember February 2020? Well, you warmed up with the RSPB’s UK garden bird watch last weekend so now take part in Jersey’s own watch, one with great significance to our understanding our closest bird neighbours. We really do need as many households to take part as possible. And what else were you planning on doing?
Song thrushes, who gave us cause for alarm only a few years ago as populations dropped rapidly, show signs that they may be recovering in Jersey. This rather strident singer is getting warmed up around now so, while half their number seem to quietly go about searching for worms on the lawn, the other half sit up in the leafless trees and belt out their (and I’m going to say it) rather monotonous song. Let’s hope that song thrushes feature in this year’s count.
Method for recording
The method of the count is very straight forward. Basically you just need to choose one of the two weekend dates (6th or 7th February), look out into the garden for a few minutes, or as long as you like (I just look out the kitchen window) and write down what birds you see and the maximum number of each species. And, of course, red squirrels count again as birds this year. Just for one weekend!
Once you’ve counted the birds (and squirrels) on your chosen day please fill out the form onlinehere. Alternatively you can download a form here and email to email@example.com or fill out the form in the JEP. This year, we unfortunately won’t be involving the garden centres because of the pandemic restrictions.
Your observations are of great importance in our understanding of the situation with the birds that we live closest too. Don’t forget, how these birds are fairing in the 21st century says a lot about our own lives and our own environment. You can read about the results of our survey to date in the Jersey Garden Birdwatch Report 2002-2020here
“In a hole in the ground there lived a hobbit puffin. Not a nasty, dirty, wet hole, filled with the ends of worms and an oozy smell, nor yet a dry, bare, sandy hole with nothing in it to sit down on or to eat: it was a hobbit puffin-hole, and that means comfort.”
And so the story begins for the puffins, I mean the hobbits, according to J.R.R. Tolkien, of course. I could be forgiven for hoping that J.R.R.Tolkien was inspired by puffins when he devised the short, wobbly, round-bellied, food-loving, funny-looking creatures that live in a hole in the ground, which he named hobbits. Even his own fictional etymology traces the word to ‘holbytla’, which he created by combining the two real Old English words ‘hol’ (hole) and ‘bytland’ (to build) – a name that would be not completely unfit for the puffins either.
Like hobbits, Atlantic puffins build their homes underground, digging holes using their bills and powerful claws, to create a tunnel that leads to a larger inner chamber for the nest. And also like hobbits, puffins like their home comforts and line their nests with soft grasses and feathers, to keep the egg and later the chick safe and warm. They are very tidy too, and manage to keep the chick clean by using a toilet chamber located in a bend before the main room.
And finally, like hobbits again, they do not like unexpected visitors, defending their burrows from envious neighbours, fighting food thieves like gulls, and avoiding, however they can, attacks from invasive predators such as rats, cats and ferrets.
Knowing all this, Birds On The Edge has been trying to improve the homes and breeding grounds of our Jersey puffins, especially in view of he precarious state of the population – down to four pairs from more than a hundred in the space of a century. Sadly, this follows the trend of many other puffin colonies around the world, which have declined or collapsed due to causes ranging from loss of habitat, predation from invasive species and human-caused disturbance, amongst others.
Over the last year we have been monitoring the puffins and other seabirds in their breeding cliffs of the north coast, studying the potential predators in the area and noting the presence of people for leisure and commercial purposes too.
We have also built and installed puffin nest-boxes in some cliffs in the north coast, so that they can be used as artificial burrows by prospecting new pairs. Our breeding puffins, all four pairs of them, already go back to the same burrow each year, so with the boxes we are hoping to attract new pairs recruiting into Jersey’s population, especially ones who were born here and are ready to settle (puffins take 5-6 years to be mature).
As for the boxes themselves, there have been various designs, all following the concept of a tunnel leading to a main chamber. We have stuck to this, building a closed box with a roof, which is completely buried. The access to the chamber is via a 1m-long pipe which is buried too, so that the entrance from outside looks like a hole in the ground. The box is almost one metre long and has a small partition near the entrance, to create the illusion of the toilet chamber, should they like to use it for this purpose. As finishing touches to the installation we packed a layer of mud and soil against the back wall, to give the puffins the chance to dig a bit if they wanted to, without going too far, and for the same reason the boxes have no floor, but a good layer of soil so that the puffins can shift the ground about and decorate their nest as they please.
Digging and burying the boxes in the cliffs wasn’t an easy task; Geomarine sent their “rope team” to assist the rangers of the National Trust and Natural Environment for the job. The team successfully installed some of the boxes in an otherwise inaccessible slope, which was deemed suitable for the artificial burrows.
With the breeding season upon us and our puffin pairs due to arrive anytime now, we will be keeping a close eye on the seas around Plémont, hoping to see the faithful locals come back to their usual spots, and even better to see new pairs flying into the cliffs, their purpose-built homes waiting for them.
The boxes might be a bit too small for a hobbit, but we hope our puffins will approve of their very own Puffin Shire.
Choughs and staff have been battling storm-force gales this month. With fewer insects around most, if not all, of the birds have been appearing at the supplemental feed fuelling their travels around Jersey’s coastline.
Here is what else we’ve been getting up to in December…
Cosmetic surgery on Wally’s Christmas wishlist?
Wally is currently sporting an overgrown upper mandible. Photo by Liz Corry.
Wally and juvenile Dary both have overgrown bills. From observations it looks to be the upper mandible that has overgrown rather than the tip of the lower mandible breaking off. This should not be a major problem, however, it may reduce the effectiveness of their foraging skills. Hopefully natural wear and tear will eventually rectify the situation. Watch this space.

Habitat use in December

Observations at Plémont over the Christmas period suggest that the area is no longer being used by choughs as a roost site. To be expected with the disappearance of Earl although it would have been nice for Xaviour to remain there with her new partner. We could do with finding out where she is roosting as it may tell us where she will nest in 2020.
There could be ‘new’ roost sites around the Island that we are not aware of. One chough was observed flying west after the supplemental feed roughly 30 minutes before sunset. Annoyingly, having just come from a fruitless search of Le Pulec to Plémont, all I could do was watch as it disappeared behind the tree line at Crabbé. From there it could have gone in any direction…including back to Sorel.

We have had a couple more reports of a pair of choughs around Grantez and the adjacent coastline. One sighting from an ex-chough keeper referenced the land behind St Ouen’s Scout Centre.

It is impossible to see leg rings in the photo, but it does show the type of habitat the choughs are willing to explore in Jersey looking for food. There are several houses nearby and the area is a popular spot with dog walkers. Let’s hope we get more sightings reported and the pair’s identity solved. Remember you can send in sightings by clicking here.

Kevin has lost his yellow ID ring so for now he is just white left. We will try and rectify this in the New Year when the force 9-10 gales hopefully die down making the catch up less like Mission Impossible.
Kevin can only be identified from his white 2015 year ring after losing his yellow ID ring. Photo by Liz Corry.
Luckily he is easy to spot as he is normally with his partner Wally. A couple of the other choughs are proving harder to ID despite having all their leg rings. Take Morris, he has a grey over cerise ring whilst Baie has pale blue over cerise leg rings. It’s not easy to distinguish the two colours especially when the low winter sun is beaming directly on the birds. There are three of us who work out at Sorel and we have all mistaken one for the other at some point.
All this means we might not realise a bird is missing/dead straight away. As the month (and year) draws to a close we have been trying to determine exact numbers. Where possible both myself and Flavio have headed out to the coast; one staying at Sorel whilst the other heads to a different known foraging site(s). It feels a bit like a wild goose chase…but with choughs.
Counting choughs…or is it sheep? Photo by Liz Corry
Our best guess is that there are now thirty-five choughs living free in Jersey; twenty captive-reared, fifteen hatched in the wild. We have not been able to account for any extras at Sorel throughout December.
December’s persistent gales have taken their toll on the aviary. So much so that an external hatch door came off its hinges and landed inside the aviary. The cable-ties securing plastic side panels in place to provide shelter from the winds) snapped off. Not once, but three times. The vertical anti-rodent guttering snapped off. And to top it off, holes appeared in the netting along the top. Possibly rodent-related although this could also be because the netting rubs on the support pole in the winds.
Still, despite the Force 10 battering, it has fared better than the Motocross track whose observation tower and trailer blew over!
Christmas Day at Sorel was a very different picture to the last three weeks of wind, rain, and hail. Photo by Liz Corry.
The one upside to all the rain appears to be how useful the dirt tracks have become to the choughs. Birds were spotted probing the muddy ruts for insects, drinking from the puddles, and hanging out on the field gate.

Kentish chough developments
At the start of December (when the ferries were still sailing!) I was invited over to Kent to assist with planning the Kentish chough reintroduction. My first day was spent with the team visiting potential aviary locations and discussing suitability.

Several landowners already work towards restoring habitats that will benefit choughs. The National Trust for example graze ponies to improve the flower-rich grassland. Short grass and insect-attracting dung – what more could a chough ask for? The challenge Kent face is working in such a densely populated area. Dover is a smidge different to Sorel.
The National Trust are just one of the many stakeholders involved in the project. Photo by Liz Corry.

My second day was at Wildwood Trust, home to the captive choughs. A morning of meetings resulted in potential research collaborations and a few ideas for how to manage the Kent releases.
Signage at Wildwood mentions the success of our chough work. Photo by Liz Corry.
Wildwood are also involved in exciting projects to rewild nearby forest as well as several exciting projects around the UK. It was nice to see behind the scenes and talk about something other than choughs! The photo gallery at the bottom shows just a few of the species Wildwood conserve.
I gave a lunchtime talk to staff about the Jersey project and the lessons we have learnt. I gave the same talk on the final day for the Kent Wildlife Trust. That talk was held at the Tyland Barn Centre and streamed live to staff at their other reserve centres. The trust are heavily involved in the public engagement side and particularly interested in how the Jersey community have reacted to the choughs.

A little later than in previous years, we are very pleased to update everyone on the Channel Islands’ birds. Two new species were added to the Islands list and unlike some of last year’s (here) they were ‘proper’ species, not those cryptic ones hiding in plain sight. Although Guernsey did add the previously ‘hidden’ Iberian chiffchaff and Caspian gull to their own list in 2018.
With some revisions (Jersey’s saker falcon, probably an escape, was demoted), the overall total for the Islands only actually went up by one so now stands at 377. I was right, last year, that Alderney would add little bunting to their total but they still haven’t reached 300. Losing a bean goose (its become two species and while Jersey can confirm records of both taiga and tundra bean, Guernsey and Alderney decided that they couldn’t retrospectively confirm the tundra version) put them back one, the little bunting brought them back up to 298. The wait for 300 goes on!
And, in the separate islands, Guernsey added the three species above but also saw their first pallid swifts with birds seen in October and November. Offshore Guernsey birders recorded their Island and the whole CI’s third Wilson’s petrel. And, to rub it in with their southern neighbours the royal tern continued to hang around until May and still didn’t visit Jersey.
In Alderney, the impressive effort continued and besides the little bunting, long awaited second records of goosander, Iceland gull and Richard’s and tawny pipits were logged. There were also three records of great egret, a rapidly spreading species, and two of cirl bunting, a species, in contrast, considered to be in decline and exhibiting limited movements. Interestingly, Sark also saw a cirl bunting, their first since, well, a long time ago. Jersey has breeding cirl buntings but they were absent from the Island from 2004-2012 pointing to more movement in this species than had been expected (and look out for more news on this beautiful bird next year!).
Guernsey also recorded local rarities in Canada and pink-footed goose, penduline tit and corn bunting. Sark added records of only rarely recorded red kite, nightjar and hawfinch with their cirl bunting.
In Jersey, besides the two CI firsts, above, the first Island record of Pallas’s leaf warbler meant that a gap in the CI list was finally filled in – there have been 18 previous records of this warbler across the other three islands. There were also seconds for Barolo shearwater, little crake and Caspian gull. The little crake was found in poor health and died in care. A third common rosefinch and third dusky warbler were also notable.
Two further wading birds made contrasting appearances in the islands in 2018 with a Kentish plover recorded in Jersey for the third time since 2000 and six black-winged stilts seen (two in Jersey and four in Alderney). Kentish plover is a former breeder in Jersey, Guernsey and Alderney (last breeding in 1974) whereas the stilt was only first seen in the islands, in Guernsey, in 1987 and has now been recorded in 13 separate years.

In May this year, Jersey’s States Assembly declared a Climate Emergency (see subsequent report here). As you know, trees and hedgerows play a vital role in capturing and storing atmospheric carbon dioxide as well as providing an important habitat for our local biodiversity.
A blog post about cute pigs?! Nah. I’m just throwing you off the scent. Click bait. It is the monthly chough report of course with everything that happened in September.
Scoping out the racecourse
The chough flock spent at lot of time in September foraging around Les Landes Racecourse. There appeared to be plenty of insects available in the soil. Leatherjackets (cranefly larvae) from the looks of things although viewing through a scope a some distance adds uncertainty.
We still have a fair few turn up at the supplemental feed. The noticeable difference is that they are taking less food. Instead of finding empty food dishes within an hour of food being put out we find leftover pellet. Presumably because they have eaten so well out and about in the mornings.
Our rodent-proof food stands mean we can leave the leftovers for the choughs to snack on later. Hunger should not be a problem for Jersey’s choughs this month!
Class of 2019 suffer another setback
Another dead juvenile has been found out on the north coast. The body was found by a dog walker near Devil’s Hole. The lady regularly visits Sorel and knew when we would be feeding so kindly handed over the remains. We identified the bird as PP042 who fledged this year in the quarry. Not a huge surprise as they were on the missing birds list.
The surprise was the condition of the bird…headless and, on X-ray, very broken. You can see shattered bone in the left humerus (circled red in the image below). Our vet was a bit baffled at the post-mortem. The injuries sustained are something he is more familiar with seeing from a bird that had been hit by a car. Plus we don’t know if all this happened after the bird died or before.
We do know this means there are only 11 juveniles remaining. Three of those have not been seen in a long time. If they are still unaccounted for in October we will have to assume the worse.
PP035 is one juvenile very much alive and kicking. She was caught up mid-September because one of her plastic rings was unraveling. Not an easy thing to do for a bird to do. It would have required force. The ring was replaced and this time a lot of glue was used to seal the overlapping edges. She looked in good health and was released straight away.
The flock of sheep at Sorel were moved off site this month as part of their management plan.
There was, however, one little sheep who avoided the round-up. We found her merrily grazing away at the aviary. She had pushed through the fencing and entered the hedgerow bank rather cunningly hiding in the hedgerow when the shepherd was around and reappearing at the chough feed.
With a bit a team work and a lot of patience she was eventually moved out (it gave our push-mower a bit of a break!).
After seven years of working out at Sorel it felt quite eerie to visit and have no sheep and no choughs*. You can still find the sheep in various locations around Jersey doing their bit for conservation grazing. Maybe it could become the next rewilding game #whereswoolly?
*don’t worry we haven’t removed the birds, they do that themselves by flying off during the day.
Flocking season in the Zoo
At this time of year, with breeding over, we normally move all the Zoo choughs back into one aviary. This mimics the flocking behaviour you see in choughs over winter. However, this year was a bit different.
This is the first year we have had only one breeding pair at Jersey Zoo. It is also the first year we haven’t released parent-reared chicks. So that means trying to mix a family of four with the only other chough we have – Gianna.
Normally the other choughs ignore Gianna, but with one family and an uninvited guest in their territory things are a little different. We have made three attempts to mix Gianna with the group this month. The first time we assumed tensions were high because the male in the family had only just been moved back. He had been housed separately for the past two months due to bad behaviour. We gave him some more time to settle in and calm down before the next attempt. No change. We waited again. Surely the hormones had settled? Nope.
As soon as I leave the aviary the pair fly over and shout loudly at Gianna. If I then walk away from Gianna, they dive-bomb her and it gets physical. Thankfully, Gianna is thick skinned and once I’m back inside with her she returns to preening and picking out insects.
Sadly for Gianna I can’t live in the aviary and be 24-hr bodyguard (although the rent would be free). She has been moved back to her off-show aviary and might have to stay in there over winter.
New placement student
If Gianna does have to stay off-show she will receive lots of attention because….fanfare please…we have a student placement again! After more than a year with a vacant position, Flavio has joined the project.
He is with us until March and has already got stuck in to the task at hand. As evident in the video below. Faceal sampling for health checks, camera trap reviews for roost ID, and dealing with a dead chough all in Week 1.
Flavio has previously worked on a beetle conservation project in the UK so we are hoping to put his survey skills to use in Jersey. His mode of transport is a bicycle so be sure to give him a wide berth if you are overtaking – he has an expensive scope in his bag. I wouldn’t want it damaged!
The annual Inter-Islands Environmental Meeting was held in Alderney this year hosted by the Alderney Wildlife Trust. With the theme of Wilder Islands, delegates attended a two day symposium highlighting work carried out across the Channel Islands, Isle of Man and islands of the British Overseas Territories. Birds On The Edge was represented by myself and Cristina Sellares with Glyn Young joining on the challenging third day.
The third day was a mixture of talks and working groups tackling the challenges islanders face with biodiversity and climate change. Tony Juniper gave the introductory keynote speech.
We were also treated to an evening lecture from Dr George McGavin the esteemed entomologist and patron of the Alderney Wildlife Trust.
A separate blog will be posted going into more detail. The highlights for this report include the mention we got in Jamie Marsh’s talk on the white-tailed sea eagle reintroduction in the Isle of Wight. Guess where we might be taking choughs next? And our first possible sighting of a Jersey chough visiting Sark! Suffice to say our holidays work plans for 2020 are quickly filling up.
Building on the success of the Jersey choughs, can reintroduced choughs help restore Kent’s chalk grasslands? Could we eventually join the Cornish population and Kentish population to bring back this charismatic bird to England’s entire south coast as in days gone by? Ok, that last bit is jumping the gun. Although it is early days, the KCP are certainly working hard to make sure the first aim is achievable.

No one can have failed to pick up this week that our environment and the biodiversity that we are a part of is under severe threat. Our very future is being debated. The Great Garden Bird Watch in Jersey may seem trivial by comparison but, like its counterparts in the UK (this year’s 40th Big Garden Birdwatch) and elsewhere, it represents a remarkable piece of citizen science that is truly encouraging in the face of such gloom. Each year, supported by the Jersey Evening Post, we encourage people across the Island to spend time on one day over a February weekend to count the birds they see in their garden, typically with the annual threat of atrocious weather, and tell us how many they see.
During this year’s count, our 18th since we started in 2002, 231 households sent us records of their birds. It wasn’t the highest number that we’ve had back but it has been important in establishing very visible trends, showing how those birds that live the closest to us are faring in today’s world. We need this kind of information if we are going to persuade our governments and those around us that Nature needs our help. Don’t forget, if the birds that have chosen to live closest to us are not doing well, what does that say about our own future?
Counts like this are also good for us, we can watch our birds, enjoy their presence and make ourselves happier and healthier. Proximity to and enjoyment of Nature are well known to help our own mental wellbeing (see discussion here) while another study of people who feed and watch birds found that people generally believed that their bird feeding benefits garden birds. They indicated that natural factors (e.g. bird abundance, disease prevalence) and abiotic factors (i.e. cold temperature) had more of an influence on how much they feed birds than internal constraints such as time and money (see link below). We like feeding ‘our’ birds and its good for their survival and its good for our health.
Back to our latest count (here) Jersey’s counters reported 40 different bird species in our gardens. Well 40 birds and red squirrels. Some birds are very rarely counted and hard to analyse so we base or long-term study of population trends of the 16 most reported species, the Big 16. We don’t include herring gulls as many people actively dissuade them so that counts of them may be skewed. See full results for the Big 16 here
Each year, members of The Big 16 may change position in our little table. In 2019, in order of commonness they were:
Species: Average per reporting garden
House sparrow 6.9
Wood pigeon 1.77
Great tit 1.6
Blue tit 1.6
Collared dove 1.4
Song thrush 0.26
Great spotted woodpecker 0.12
Our honorary bird, the red squirrel, at 0.4 per garden, would have been 12th.
The relative fortunes of the Big 16 over the 18 years of the count can all be seen in our report (here). There has been a slow decline in overall numbers of the 16 with some very obvious losers, species that are losing ground like greenfinch and starling, and winners like goldfinch, wood pigeon and blackcap. One very encouraging trend has been the recovery of the house sparrow, a species inextricably connected with people that had been disappearing from large parts of the British Isles. It’s doing ok in parts of Jersey!
There are some interesting comparisons. We have more of those lovely house sparrows while starlings and blue tits are definitely missing out in Jersey.
So, in Jersey we can see well how our bird neighbours are doing. And it is undoubtedly a mixed picture. We need to highlight what’s happening, we need to continue to help our garden birds and we need to take part in next year’s count. Watch this space!
