Antrim Marina (Monday 28th August 2023)


      Antrim Marina - Monday 28th August 2023       
Today was my 5th weekly visit to Antrim Marina, where I am studying a wintering population of Black-headed Gulls, some of which were colour-ringed at the site.  It was a calm, but cloudy day, with the temperature reading 20°C.  Today, I arrived at 10:30, remaining to 2:30pm.

With practically no wind, the majority of the Black-headed Gulls rested on the roof of the 'Gateway Centre' which is not helpful when trying to read rings.  At times, a good number of birds would come to ground, especially when folk arrived to feed the ducks.

It was another poor day for overall numbers, with a high of around 70 Black-headed Gulls.  Up until today's visit, only 18 colour-rings out of a total of just under 50 had been read so far this winter.  At 11:11, I spotted a new arrival -  2FHT , and despite knowing it was one of my birds, no bells were ringing in my head about this birds history here.

When I returned home, I checked my records to find that I had ringed -  2FHT  as a juvenile/1st winter bird here at the Marina, on the 8th November 2021.  After being ringed, I recorded the youngster on three occasions (15th November 2021, 29th November 2021 and on the 6th December 2021), and never saw it again at the Marina after that. On Christmas Day 2021, which is the day I always go to Connswater Shopping Centre in Belfast to read rings, I stopped by Antrim's Baptist Church, and discovered -  2FHT  on the roof.  Nothing more was heard of the bird until the 13th December 2022, when Suzanne Belshaw photographed the gull on the Whiteabbey Shore breakwater on Belfast Lough, which was the final sighting until the bird turned up here today at Antrim Marina - or so I thought.

When I went to submit today's sighting onto the BTO's DemOn Ringing Database, I noticed that there were two sightings entered which I knew nothing about.  DemOn does not show the locations of ringing or for re-sightings.  With these unknown sightings having been made on the 9th & 12th March 2023, I requested a copy of the recoveries, and boy, was I in for a surprise.

Both sightings had been made at the Marina in Gdynia on the north coast of Poland, the distance from Antrim Marina, being 1,595 kms / 991 miles (E).  The duration as of today's sighting, is now 1 year, 9 months and 20 days.  The only question now, will -  2FHT  stay at the Marina throughout this winter.

With no further returnees, my total before next week's visit is now 19 colour-rings.  At 11:50, the Icelandic metal-rung Black-headed Gull -  543335  appeared.  I made another attempt to catch this bird as it is so people friendly.  Using the swans as cover, the bird made it's closest approach yet, and I was just inches away from catching it.  If I can get a colour-ring onto this bird, there will be a far higher chance of it being seen when it returns to Iceland next spring.  I am still waiting on the ringing details for this gull, as the ringer concerned is being pursued by the Icelandic Institute of Natural History.

With the addition of -  2FHT , 15 colour-rings were read today, so I had 4 absentees.

Other Birds at Antrim Marina
Today, I had a rare visitor to Antrim Marina, in the form of a Mediterranean Gull.  If memory serves me right, this is only the second Med Gull that I have seen here in 11 years of visits.  A juvenile Med Gull was recorded here on the 19th September 2021.

I am still waiting to record my first Common Gull this winter which is strange, as in the past, the odd bird or two would have been recorded by this time of the year.  The pair of Herring Gulls, sat on the roof of the 'Gateway Centre' throughout my visit, and I reckoned the same adult Lesser Black-backed Gull came and went on several occasions.

No sign of the Mute Swan family today, with the four cygnets, but three un-ringed swans were present throughout my visit.  Mallard numbers were down slightly this week, with around 50 on my arrival.  By the time of my departure, numbers had dropped to around 25 birds.  Not surprising really, as they benefited from several feeds of bread and biscuits.

3 Hooded Crows and 3 Jackdaws, were the only other species noted today.

Mute Swan Sorted...


      From Declan Clarke       
During a visit to Ardglass Harbour on the 18th August 2023, Declan Clarke came upon a small group of Herring Gulls, two of which were colour-ringed.  On taking a photo with his phone, both gulls were from the Isle of Man, ringed -  G05:M  and  H16:M   Declan sent an email to Mark Fitzpatrick and a reply was duly received.  It turned out, that both birds were first re-sightings since being ringed.

 G05:M , was ringed as a chick, on the 1st July 2022, on the Calf of Man, Isle of Man.  The duration since being ringed, was 1 year, 1 month and 17 days.

 H16:M , was ringed as an unsexed adult, on the 15th October 2022, also on the Calf of Man.  The duration for this gull, is 10 months and 3 days since being ringed.

The distance from the Calf of Man to Ardglass Harbour, is 57 kms / 35 miles (WNW).

My thanks goes to Declan for his sighting report and photo, and to Mark for supplying the ringing details.

      From Suzanne Belshaw       
Suzanne Belshaw has been out and about visiting several sites looking for ringed birds, which has produced five re-sightings.

On the 16th August 2023, Suzanne recorded Black-headed Gull -  250B  for the second time this autumn at the Sprucefield Shopping Centre car park in County Down.  The previous sighting on the 25th July 2023, was a double sighting, as David Nixon also reported -  250B  at Sprucefield.  Having been ringed as a chick in June 2008, the duration since being ringed, is now 15 years, 2 months and 10 days.  Read about the July sightings in this blog post (read here).

The visit to the former waterworks at Cliftonville in Belfast produced two colour-ring re-sightings, one being a Greylag Goose, the second resulting with the metal-ring number for a Mute Swan though colour-ringed -  NLX , the bird had been a bit of a mystery.

This was Suzanne's second re-sighting for -  NLX , having first recorded the swan back on the 27th January 2023.  At that time, I tried to submit the sighting by the bird's colour-marks only, but the BTO had no record of that colour-code having been used.  On her latest sighting, Suzanne also recorded the metal number -  Z78598 .  This time, on submitting both sightings giving the metal number and colour-code, we received the ringing details from the BTO.  The Mute Swan was ringed as an adult male on the 4th September 2020, here at the waterworks,  The duration since being ringed is now 2 years, 11 months and 14 days.

It could be possible, that when this swan was ringed originally, the metal number may have been submitted to the BTO without the colour-marks being added at the same time.  Suzanne now knows to try and obtain the metal number for any colour-ringed Mute Swans, to be sure of getting a result.  This would also be helpful, if a previously metal-rung swan, is fitted with a colour-ring on a later date.

The re-sighting of a Greylag Goose rung (White) 016, was Suzanne's fourth for this bird, with all four sightings having been recorded at the waterworks.  (White) 016, was ringed at the waterworks as an unsexed juvenile on the 18th August 2020.  The duration since being ringed is now 3 years to the day.  Although Suzanne had no idea about the duration, a birthday card would have been nice.  It's always good to follow a bird of known age.

At Carrickfergus Harbour on the 19th August, Suzanne recorded her first sighting of a Danish Black-headed Gull rung -  VA5454 , though this was the third re-sighting overall.

 VA5454 , was ringed as a chick, on the 25th May 2020, on Hirsholm Island just off the north-east coast of Denmark.  The then juvenile, was first recorded in Northern Ireland, on the 4th January 2021, when Cameron Moore spotted the gull on the seawall at Rhanbouy Park in Carrickfergus (Photo).  The following winter, Cameron recorded the bird's return to Rhanbouy Park (shore), on the 4th November 2021.  Rhanbouy Park is about half a mile south from Carrickfergus Harbour.

The duration since being ringed, is now 3 years, 2 months and 25 days, and the distance from Hirsholm Island, is 1,063 kms / 660 miles (WSW).  Seeing as there were no sightings in 2022, it is nice to know that this young gull is alive and well.

A late addition to this post, was the re-sighting of Black-headed Gull -  EZ02451  at Lurgan Park Lake in County Armagh, on the 23rd August 2023.

 EZ02451 , was ringed as a chick, on the 20th June 2017, at the Elvanfoot colony in South Lanarkshire, Scotland.  Normally, the chicks are colour-ringed at this site, but with an exceptionally high number of chicks at the site that year, the ringers exhausted their supply of colour-rings, hence this bird being ringed with a metal-ring only.

This latest sighting of -  EZ02451 , is now the 17th overall, with all sightings having been recorded here at Lurgan Park Lake by Suzanne.  The first sighting was made on the 7th September 2017, at which point the duration was just 2 months and 18 days (Photo).  This gull has now been recorded at least once every winter since 2017.  The duration, is now 6 years, 2 months and 3 days since being ringed, and the distance from Elvanfoot to Lurgan Park, is 202 kms / 125 miles (WSW).

My thanks to Suzanne for her latest sightings complete with photos.

Antrim Marina (Monday 21st August 2023)


      Antrim Marina - Monday 21st August 2023       
Today saw me making my fourth weekly visit of the 2023/2024 autumn/winter season at Antrim Marina, to study the wintering population of Black-headed Gulls.  It was a cloudy, but warm day (21°C), with a very strong wind blowing in from the west over Lough Neagh.  Unlike the previous visits, the strength of the wind kept the gulls off the roof of the 'Gateway Centre'.  On my arrival, around 70 Black-headed Gulls were dotted around the jetties and the front car park.  Taking my gear out of the boot of my car, I nearly 'died' as I realised that my most important piece of equipment - my camera, was left sitting on a kitchen chair back home.  I chose a later start than normal, arriving at 12:30 and departed at 4:30.

With the addition of -  2AAN  and  2BRD  last week, the overall total of colour-ringed Black-headed Gulls now sat at 18 out of a total of nearly 50 rings read here last winter.  Although 70 Black-headed Gulls were present when I arrived, numbers decreased slightly over the course of today's visit.  By the time of my departure, 14 out of the 18 colour-ringed gulls recorded in prior weeks were recorded today, and more concerning, was the fact that no more returnees were recorded.

I could be wrong, but the way things are looking at the present, many of my study birds are not going to make it back this winter.  Some of the earliest colour-ringed gulls, which were ringed here as part of Adam McClure's former Northern Ireland Study, should have been on site by the beginning of August.  These are the likes of -  2AAA  2AAK  2ABL  and  2ABN .  Another bird -  2ABS , was last seen on the 7th November 2022, and I'd be fairly certain now that this one has perished since then.

There are also lots of gulls missing that I have ringed over the course of the last couple of winters.  Has 'Bird Flu' taken it's toll on many of them?  One bird -  2FFC  was found dead at a breeding colony in Germany over the summer, with this gull testing positive for the virus.  Two gulls among today's list of re-sightings -  2ACV  and  2FFX , survived through the outbreak of 'Bird Flu' at the RSPB's Window on Wildlife Reserve in Belfast this summer.

Back on the 8th August 2023, a metal-rung Black-headed Gull appeared, and this bird turned out to be an Icelandic bird.  Having only taken a couple of photos, the gull flew off, leaving me two digits short of completing the whole number on the ring -  543335 .  The gull was very comfortable being around people feeding the ducks, so I thought there would be a good chance of competing the number at some point should it remain in the area.  During my visit to the Marina last week, there was no sign of the gull, which left me wondering if it was still about.

Around 1:45pm during today's visit, I spotted a gull with an upside-down metal-ring, telling me my gull was back again.  Having forgotten to bring my camera along today, I chased after the bird with my telescope and I was fairly sure that the last two digits read ' 35 '. thus giving me -  543335 .  Again, I saw that the gull was ultra confident at being around people, so I thought at having a go to try to catch it whereby I could fit a colour-ring onto it's right leg.  Dropping bread between the legs of the swans on the slipway, my bird made its way directly behind the swans and was reluctant to come any closer.  I reckon that I will have a good chance at catching the bird in a few weeks time, once there is less natural food for the gulls to eat.  Later in the evening, I decided to take a chance that I had read the number correctly, and sent an email to the Icelandic Institute of Natural History.

On the following day (Tuesday 22nd August), whilst sitting having my breakfast, I decided that I should go back to Antrim Marina with my camera.  Having submitted seven recent ring sightings to the BTO, I made my way back to the Marina.  Having arrived, about two dozen Black-headed Gulls were present.  After a short, but heavy shower of rain, I began to search through the gulls with my binoculars and spotted my Icelandic bird resting on what used to be, the short wooden jetty.  Moving my car closer to the jetty, I began throwing out bits of bread which drew my gull closer to me and I took lots of pictures of the ring.  I was correct with the ring reading -  543335 .

I returned home well pleased, and a short time afterwards, a reply arrived from Iceland.  The Icelandic Institute of Natural History did not have the details for my gull, except to say that it had been ringed this year.  They will get in touch with the ringer and will send me the details once they have them.  Seeing as this bird was only ringed this year, there could be a good chance that it has wintered at the Marina in the past.

Other Birds at Antrim Marina
Today was yet another poor day concerning other species of birds visiting the Marina.  A pair of Herring Gulls was present throughout my visit, and presumably, the same Lesser Black-backed Gull frequently came and went.  I am still waiting to record the first Common Gulls of the autumn/winter season, especially that of the small female metal-rung bird from Scotland.  This one first appeared here as a juvenile in February 2014, and has wintered in the area around Antrim Marina every winter since.

The Mute Swan pair, along with their four cygnets were also present throughout today's visit.  Just before I departed at 4:30, a further four adult swans arrived, though none of these were ringed.  Again, the Mallard numbers were around the 60 mark, and still no rings among them.

A juvenile Cormorant seen at 1:22 was first seen in front of the slipway diving for fish, and then slowly made it's way up-river.  2 adult Jackdaws and a single juvenile completed today's list of other bird species.

Godwit Solved...


      Black-tailed Godwit       
Last week I reported on four colour-ring sightings that were made by David Nixon at Dundrum in County Down.  One of these included a Black-tailed Godwit, which I dismissed, as I reckoned it belonged to a certain ringer who does not respond to sightings.  Unfortunately, the ringer concerned is using a colour-ring sequence that is registered to another ringer.  At present, David is having problems in trying to download photos from his camera, but he used his phone to photograph the godwit through the viewfinder on the camera.  The bird has a red ring above it's right knee, with what appeared to be yellow/orange/yellow below the knee.

It was thanks to Graham McElwaine, who suggested that David's Godwit, could actually be the same bird that David recorded at the same location (Dundrum Inner Bay (North)), on the 5th October 2022.  This prompted me to check up on the photo that David took at the time, but instead of yellow/orange/yellow, the bird was ringed yellow/red/yellow.

David sent an email to Antonio Fernandez Cordeiro concerning the latest sighting of R-YRY.  A reply was received on the 15th August 2023, on the same date that Graham himself had also spotted R-YRY, this time on the high tide roost at Dundrum Inner Bay (South).

R-YRY, had been ringed as an un-sexed 2nd Calendar Year bird, on the 18th January 2019, in the Arnosa area in north-west Spain (Map).  Since being ringed, the bird has been recorded on many occasions in Spain, including five sightings since David first recorded the bird here last year.  Outside of Spain, two other sightings were made by Tom Cooney in September and October 2021, when spotted at Dundalk Bay in the Republic of Ireland.

The distance to Dundrum from Arnosa, is 1,337 kms / 830 miles (N), and the duration up until Graham's sighting on the 15th August, is now 4 years, 6 months and 28 days.

      Herring Gull Recovery       
Last week, I also reported on the sighting of a juvenile Herring Gull that was spotted by Cameron Moore at Whitehead in County Antrim.  Ringed -  117:C , I sent an email to Roisin Kearney as I believed the bird was from a new ringing project on the Copeland Islands in County Down.

Roisin replied to say that her new ringing project began this summer, with this ring series being used on both Herring and Lesser Black-backed Gulls.  A total of 102 Herring Gull chicks, 46 Lesser Black-backed Gull chicks and 5 adult Lesser Black-backed Gulls were colour-ringed this summer.

Cameron's juvenile -  117:C , was ringed as a chick, on the 1st July 2023, on the Old Lighthouse Island, which is the home of the Copeland Bird Observatory.  It has only been 1 month and 7 days since the gull was ringed, and the distance to Whitehead, is just 13 kms / 8 miles (NW).  My thanks goes to Roisin for the info, and good luck with the new baby.

*******************************************************

      Wednesday 16th August 2023       
Recently, I have checked the same stretch of the east County Antrim coast looking for colour-ringed Gulls.  Each time, I started on the foreshore at Glynn on Larne Lough, making my way northwards to Carnlough Bay.  Today, I made a slight detour after leaving Glynn, as I took a quick drive southwards to Whitehead.

Just one colour-ringed was spotted today, and I was lucky to get it.  I had been at Glynn for over an hour with the tide steadily receding, when way in the distance I spotted an Orange Darvic on an immature Great Black-backed Gull.  As I was on the platform of Glynn railway station, my Nikon P1000 was going to have to work hard to capture the code.

Standing on the right hand end of the railway platform, I was well into digital zoom and managed to obtain a half decent photo of the gull, though I was not able to capture any details on the ring.  Walking across to the left hand end of the platform, I captured the code -  P44:M .

Being a bird from the Isle of Man, I emailed Mark Fitzpatrick, though it took the best part of a week for a reply.   P44:M , was ringed as a chick on the 20th June 2022, on Kitterland Island situated halfway between the Calf of Man and the Isle of Man mainland.  My sighting was the first for this bird since being ringed, with the duration being 1 year, 1 month and 27 days.  I am waiting on an official recovery from the BTO, but I estimate the distance as, 107 kms / 66 miles (NW).

All of the big gulls congregated on the left hand side of the Glynn River outflow, whilst a nice group of mainly Common Gulls rested on the right hand side of the river.  With at least 200+ Common's, I was really frustrated as most decided to lay down on the seaweed.  I had hoped to spot one or two of my Rathlin Island Study birds and there was no sign of the juvenile Common Gull -  2L22 , which I spotted here on the 5th August 2023 - this one having been ringed as a chick back in June 2023, on the Isle of Tiree in Scotland.

Antrim Marina (14th August 2023)


      Antrim Marina - Monday 14th August 2023       
Today's visit to Antrim Marina was my third weekly visit of the 2023/2024 winter season.  Arriving at midday, the weather was calm and sunny, with the temperature gauge in my car reading 21°C.  Due to the settled conditions, the Black-headed Gulls once again decided to remain perched on the roof of the 'Gateway Centre'.  Remaining until 3:30pm, gull numbers at ground level never exceeded the 30 mark, which was not helpful when trying to read the colour-rings.

After last week's visit, with the addition of -  2FIJ  and -  2FIL , this winter's list of colour-ringed Black-headed Gulls had reached the 16 mark.  By 1:43pm, with the arrival of -  2FIF , today's total sat at 9 colour-ring sightings and then at 1:57, a couple with their two sons arrived with a paddleboard.  The two boys mucked about on the river beside what used to be the low wooden jetty, and with their presence on the water, the gulls stayed away.  Once the family departed around 2:30, some gulls started to appear again, as people arrived to feed the ducks.

My final two ring sightings of this visit, were new additions to this winter's list, with -  2AAN  appearing at 2:40,  followed by, what looked to be -  2BRD  at 2:51.  This second gull flew off just as I was trying to read the ring through my binoculars.  I grabbed my camera and frantically searched for the bird, and a few minutes later, a photo confirmed the sighting.  Although -  2BRD  was originally ringed at Antrim Marina, appearances these days are rather rare, and last winter, the gull was not recorded here at all.

The continued lack of juveniles is concerning, which would indicate once again that the Black-headed Gulls have had a very poor breeding season on the nearby 'Torpedo Platform'.  Throughout today's visit, just one juvenile was present, and due to it's settled nature of being around people, I'd be pretty sure this is the same juvenile which was here during my two previous visits.  At 2:36, a second juvenile arrived briefly, this being a recently fledged youngster as it's plumage was totally dark.

By the time of my departure, just 11 colour-rings had been read altogether, and with the addition of -  2AAN  and -  2BRD , this winter's list now stands at 18 ring sightings altogether.  Last winter's total, including newly rung birds, was just under the 50 mark, therefore at present this winter's total is still very low.  With 'Bird Flu' having caused havoc around many breeding colonies over the summer, the coming weeks will be of interest, just to see how many make it back to the Marina.  Since my visit last week,  2CJT  has injured it's left leg, and was limping heavily today.

One Black-headed Gull that I was especially wanting to see again, was the Icelandic metal-rung bird that I spotted here last week.  The gull disappeared before I could obtain enough photos of the ring to complete it's number, as I'm missing the final two digits -  5433** .  Although there was no sign of it today, the bird is people friendly, so I'm hoping that it is still about.

The first of today's two returnees -  2AAN , was caught and ringed at Antrim Marina as an adult female on the 21st December 2012, being one of the earliest to be ringed belonging to Adam McClure's former Northern Ireland Black-headed Gull Study.  Today's sighting is this bird's 291st re-sighting record, with all but one having been made here at the Marina.

Over the year's since being ringed, I had established that -  2AAN  was a winter visitor to the Marina and would usually arrive back in late July.  Where it went to breed was unknown, until a sighting was reported to me on the 16th June 2022.  On this occasion, a Geraldine Seymour photographed -  2AAN  on the Inver River in Larne, County Antrim, which suggests it could be breeding on the nearby Blue Circle Island on Larne Lough, which is an RSPB Reserve.

Larne is just 31 kms / 19 miles (ENE) from Antrim Marina, and this close proximity would explain the early return to Antrim Marina every year once it's breeding season has finished.  The duration since being ringed, is now 10 years, 7 months and 24 days.

(Ringed as an Adult Female, on the 21st December 2012, at Antrim Marina)

Once I had confirmed the second returnee -  2BRD , I was really pleased at having recorded the gull here again.   2BRD , was caught and ringed at Antrim Marina as an adult male, on the 1st February 2015.  It was the fourth of four Black-headed Gulls ringed on that day, which was the day that Adam McClure and myself met for the first time.  I recorded the bird the following week (8th February), and then on the 15th March 2015, Kevin Kirkham spotted -  2BRD  at Lurgan Park Lake in County Armagh, and this was followed up with s second sighting at Lurgan Park, when Suzanne Belshaw photographed the gull there on the 24th March 2015.

The next sighting was made by Neville McKee on the 3rd August 2015, having recorded the return of -  2BRD  to Antrim Marina.  Over the following weeks that winter,  2BRD  remained at the Marina, with the final sighting having been made on the 31st January 2016.  Since this,  2BRD  has become a rare visitor to the Marina over the following winter's, but I have no idea as to where the gull is wintering at now.

Over the years, prior to the onset of the new breeding season,  2BRD  has often been recorded at Lurgan Park Lake, arriving there in late February or early March.  Although we have no idea as to where this bird breeds at, sightings at Lurgan Park on the 26th June 2017, and again on the 8th June 2022, would suggest that the breeding site is not that far away.  Lurgan Park is just 28 kms / 17 miles (SSW) from Antrim Marina, and the duration since being ringed, is now 8 years, 6 months and 13 days (PDF).

Other Birds at Antrim Marina
The Mute Swan family with the four cygnets, were present throughout my visit today, and once again, Mallards numbers were good with around 60 to 70 present on my arrival.

An adult Herring Gull was present throughout my visit, with a second adult appearing briefly at 12:56.  An adult Lesser Black-backed Gull had also made a brief visit at 12:51.  For the third week running, there were no Common Gulls.

It was a very poor day for other species, as just three Jackdaws were the only other birds to be recorded today.

Nice Selection...


      Wednesday 2nd August 2023       
Today I had to go to Belfast to attend a job interview and the timing of the interview could not have been better.  On completion of the interview, I was only minutes away from Kinnegar Beach on Belfast Lough, and on my arrival the tide had recently started to recede.  Loads of gulls were quickly gathering on the shore, and scoping through them, I spotted two colour-ringed Black-headed Gulls.  Managing to obtain photos of both birds, the codes told me they were both Scottish.  I did not realise it at the time, the sighting of the second gull, was actually a re-sighting of a bird I had recorded in the past.

Having reported both gulls to Iain Livingstone who is the ringing coordinator for the Clyde Ringing Group, I also submitted both to the BTO.  The first gull spotted -  2HP6 , was submitted by its colour-marks only, and the BTO were able to supply a recovery.

It turns out that -  2HP6  was ringed on the same date as my second sighting here on Kinnegar Beach.  Iain Livingstone has yet to reply, but as things stand, my sighting appears to be a first for this bird.  Ringed as a chick on the 24th June 2020, the duration since being ringed, is now 3 years, 1 month and 9 days, and the distance from Elvanfoot, is 166 kms / 103 miles (WSW).

(Ringed as a Chick, on the 24th June 2020, at Elvanfoot, South Lanarkshire, Scotland)

On taking the photo of the second Scottish Black-headed Gull -  2EN5 , I hadn't a clue that I had recorded this bird as a juvenile back in 2020.  As with all ring sightings, the first thing I do, is to make a search on my Main Ring Reading Spreadsheet, just to see whether the bird in particular has been recorded in Northern Ireland at any time in the past.

 2EN5 , was ringed as a chick, on the 24th June 2020, at the Elvanfoot colony in South Lanarkshire, Scotland.  One month and two days after being ringed (26th July 2020), the youngster had moved 45 kms / 28 miles (NW), being recorded at Strathclyde Country Park, near Motherwell in North Lanarkshire, Scotland.

On the 19th October 2020,  2EN5  then turned up at my Black-headed Gull Study site at Antrim Marina in Antrim Town, Co. Antrim, which is situated 182 kms / 113 miles (WSW) from the Elvanfoot colony.  The duration at the time of my sighting, was 3 months and 25 days.

Since 2020 until now,  2EN5  went undetected.  The distance from Elvanfoot to Kinnegar Beach, is 166 kms / 103 miles (WSW), and the duration since being ringed, is now 3 years, 1 month and 9 days.

      From John Clarke       
On Thursday 3rd August, John Clarke was out walking his dog along the cliff tops just outside of Portstewart in Co. Londonderry, and spotted a colour-ringed Mediterranean Gull among other gulls on the rocks below.  On taking a few photos, John managed to capture the code -  PLNR .  John left it to me to submit his sighting, which I duly did, submitting it directly onto the Polish Ringing Database.

As yet, no information has returned, which is very unusual, as the Poles are normally very quick to reply.  A possible reason for the delay, may be a backlog of recoveries due to birds being found dead having suffered from 'Bird Flu'.  The wait continues.

      Saturday 5th August 2023       
It was a late start this afternoon, as high tide in the Larne area was forecasted for 14:41.  My plan was to start on the Glynn foreshore of Larne Lough, and make my way northwards along the east County Antrim Coast to Carnlough.

I arrived at Glynn at 4pm, and by 4:15, I spotted my first and only colour-ring over the course of this outing.  This was a juvenile Common Gull -  2L22 .  As well as reporting my sighting to Iain Livingstone, who is the ringing co-ordinator for the Clyde Ringing Group in Scotland, I also submitted the sighting to the BTO by the bird's colour-marks only.

The BTO were the first to get back to me, as they were able to generate a recovery.   2L22 , had been ringed as a chick, on the 20th June 2023, on the Isle of Tiree in the Argyll & Bute region of Scotland.  The distance to Glynn, was given as 195 kms / 121 miles (SSE), and the duration since being ringed, was 1 month and 16 days.

      From David Nixon       
On Tuesday the 8th August 2023, I received an email from David Nixon, who had earlier that day, recorded four colour-ringed birds.  The first of these, was a Black-tailed Godwit which belongs to a certain ringer who does not respond to sightings, therefore, it was decided not to pursue this one any further.

The other three, were two Black-headed Gulls and a Common Gull.  The Common Gull -  2BBC , was actually one of my study birds from my project on Rathlin Island.  Although this gull was spotted on Rathlin Island just prior to the start of the breeding season, there was no sign of the gull in any of the sub-colonies from April through to June.  The gull was not seen again, until being spotted on Ballycastle Beach, on the 20th July 2023, by Pete and Ann Wilson, who were in Ballycastle on holiday, but live in Sheffield, England.

I stated at that time, that -  2BBC  was probably on it's way to Dundrum for the winter, and this is where David found the gull today, on the high tide roost at the South Inner Bay at Dundrum.  The distance from Rathlin Island, is 115 kms / 71 miles (S).  The duration since being ringed, is 6 years, 1 month and 15 days (PDF).

On checking his notes, David's sighting of a Black-headed Gull with a White Darvic, was his second for this bird.  (White) 2499, was ringed as a chick, on the 17th June 2021, on Lough Ree in County Longford in the Republic of Ireland.  Brian Burke, who is the ringing coordinator for The Lough Ree Gull Project, confirmed that David's two sightings remain the only ones for this gull.  David first spotted the gull on the 11th October 2022, at Green Island in Dundrum Bay, just north of the town of Dundrum.  The distance from Lough Ree to the South Inner Bay at Dundrum, is 159 kms / 98 miles (ENE), and the duration since being ringed, is now 2 years, 1 month and 22 days.

When I saw the code for David's second Black-headed Gull sighting, I thought WoW.  This bird was ringed -  2EN6 , and I recorded -  2EN5  last week on Belfast Lough.  As ringing coordinator Iain Livingstone, has been slow to respond of late, I submitted David's sighting to the BTO as well, hoping that they could generate a recovery from the colour-marks only.  This time, Iain got back to us first.

As with my two gull sightings on Belfast Lough last week,  2EN6  was ringed as a chick, on the 24th June 2020, at the Elvanfoot colony in South Lanarkshire Scotland.  One previous sighting was recorded on the 5th August 2020, when -  2EN6  was spotted by Brian Henderson at Bishop Burn on Loch Ryan in Dumfries & Galloway, Scotland.  At the time, it had only been 1 month and 12 days since -  2EN6  had been ringed, and Loch Ryan is situated 104 kms / 64 miles (WSW) from Elvanfoot.

Today's sighting of -  2EN6 , takes the duration to 3 years, 1 month and 15 days.  The distance from Elvanfoot to Dundrum, is 192 kms / 119 miles (SW).  David took photos of all four sightings today, but he is experiencing some issues trying to download them from his camera.  My thanks to David for his sighting reports, and if I do obtain a copies of the photos, I will add them to this post.

      From Graham McElwaine       
Graham McElwaine has been in touch several times in recent days reporting his colour-ring sightings.  The first of these was made on the 6th August 2023, with the sighting of Great Black-backed Gull -  R32:D  at Kilkeel Harbour in County Down.

 R32:D , was ringed as a chick, on the 4th July 2020, on Dalkey Island in County Dublin, and was still on the island on the 15th & 29th July 2020.  The young gull's next sighting was made here in Northern Ireland, when spotted by Declan Clarke, on the 5th November 2020, at Ardglass Harbour in County Down.  Seven day's later, on the 12th November 2020,  R32:D  had flown back south into the Republic of Ireland when spotted at Bullock Harbour on the southern coast of Dublin Bay.

The gull was not seen again until the 15th May 2022, when Graham McElwaine had his first encounter with -  R32:D  at Kilkeel harbour, followed by a second sighting there on the 6th September 2022.  With this latest sighting at Kilkeel, it seems as if -  R32:D  has made this fishing port its home for now.  The distance from Dalkey Island to Kilkeel Harbour, is 90 kms / 55 miles (N), and the duration since being ringed, is now 3 years, 1 month and 2 days.

On the 7th August 2023, Graham made two visits to Ratallagh Beach which is just south of Portavogie in County Down.  During each visit, a colour-ring was spotted, though these belonged to two separate gulls.  Graham reported them as Black-headed Gulls, ringed - (White) 30PT and -  PLX6 .  I was a bit sceptical about (White) 30PT, as 3*** is a Belgium ring, and are used to ring Mediterranean Gulls.  I went onto the cr-birding site, and made a search for Black-headed Gulls ringed - White '3', but did not get a match, whereas a similar search for Mediterranean Gulls, gave me a result.

I emailed Camille Duponcheel concerning Graham's sighting of (White) 30PT, citing that it was reported as a Black-headed Gull, but we would settle on Camille's response.  Camille was very quick to reply, to say that (White) 30PT, was a Mediterranean Gull.  Although most of this ring series are used in Belgium, some rings are also used in Holland, as was the case of Graham's bird.

(White) 30PT, was ringed as a chick on the 1st July 2021, on one of a group of islands known as Ventjagersplaten, on the Haringvliet Inlet just south of Rotterdam, Holland.  Three previous sightings were made in August 2021 in Norfolk, England, February 2022 in Spain and in May 2022 in France.

I have submitted Graham's sighting to the BTO, but it may take a while before we obtain a recovery.  I estimate the distance from the Haringvliet Inlet to Ratallagh Beach, as being roughly 720 kms / 447 miles (NW), and the duration since being ringed, is now 2 years, 1 month and 6 days.

Graham's second Black-headed Gull -  PLX6 , also had me second guessing, as it is a Polish bird.  Polish Black-headed Gulls previously recorded in Northern Ireland, have always been colour-ringed with either White or Yellow Darvics, but Red would be a first.  Polish-rung Mediterranean Gulls recorded in Northern Ireland, have always been ringed with Red Darvic's with ' P ' as the starting letter (an example is John Clarke's sighting above).  I went onto the cr-birding site to look for Black-headed Gulls with Red Darvic's starting with the letter ' P ', and did get a match for Poland.  I went ahead and submitted Graham's Black-headed Gull onto the Polish Ringing Database, but as yet, there has been no reply.  Will this one come back as a Med Gull as well?

Graham's final colour-ring sighting, was made on the 9th August 2023, when he spotted a Herring Gull -  H14:M , at Millquarter Bay in County Down.  Graham reported the sighting directly to Mark Fitzpatrick, who is the ringing coordinator for the Isle of Man.   H14:M , was ringed as an unsexed adult, on the 15th October 2022, on the Calf of Man.  This sighting is the first for the gull, coming 9 months and 25 days since being ringed.  The distance from the Calf of Man to Millquarter Bay, is 57 kms / 35 miles (WNW).

      From Cameron Moore       
A phone call from Cameron Moore came on the evening of the 9th August 2023.  I was asked if I could send a text message with my email address added, as his son has had problems with a computer.  Cameron is not computer savvy, and therefore relies on his son to download photos and send emails.  Whilst on the phone, he reported the sighting of a juvenile Herring Gull, rung -  117:C .  I normally associate ':C' as gulls having been ringed by the Clyde Ringing Group in Scotland, but these are normally White Darvics with Red Characters.

Whilst Cameron was still on the phone talking about the non-appearance of Terns so far this autumn, I had a quick check on the cr-birding site, and discovered that this ring series belonged to Roisin Kearney.  Through the BTO's Katherine Booth Jones, I knew Roisin was due to begin a new colour-ringing project on Lighthouse Island which is the home of the Copeland Bird Observatory in County Down, and these were to be used on both Herring and Lesser Black-backed Gulls.

I received photos the following afternoon and then emailed Roisin concerning Cameron's sighting.  As of today (Saturday 12th August), I have not received a reply and have decided to go ahead and publish this post.
