Hybrids Fledged...

I'm running late again with my latest post.  With so much to do, both at home, and, out and about, time just flies by.  There are a few outings that are not included in this post, but these tend to be more insignificant.  One of my most important tasks, was to verify the fledging, of my Med x Common Gull chicks.  The problem was, they just look like pure Common Gulls.

Having said that, I recently had a 'colour-ringed' Common Gull reported to me, that was actually a young Mediterranean Gull, which was ringed in Germany.  This highlights, how little difference there is between the chicks of the two species.

One interesting fact, is how quick the German youngster made it's way to Northern Ireland, as, at it's earliest, it would have been ringed in the latter part of May.  It turned up in Whitehead, on the 17th July, and another German 'colour-ringed' youngster, was spotted at the Belfast RSPB Reserve on the 20th July.  Apparently, the ring codes were different on both birds.

I recently checked the live Norwegian and Polish Ringing Databases, to check on the progress of their gulls which winter in Northern Ireland.  Some of the gulls, that are normally recorded back home, have not been re-sighted.  Have these birds perished?  This is something, we'll have to check out this winter, when the gulls should return to their favoured sites.

Hybrid Success

On Sunday 8th July, I had hoped to get away to do a bit of birdwatching/ring reading, but couldn't get away, bar a small window of time.  I had planned to visit the Tesco Warehouse in Antrim, in the next few days, but decided to carry out a quick visit today instead.

On my arrival, I walked up to the perimeter fence and could hear quite a commotion, as young gulls were on the ground.  I then noticed three adult Common Gulls and a Mediterranean Gull, plus four chicks.  Two of these chicks obviously belonged to the Med x Common Gull pair, but after numerous photos from distance, all the chicks looked like Common Gulls.

I drove around to the security hut, not really expecting to gain access to the premises to obtain close up photos of the youngsters.  I was correct in my assumption, security had no power to let me on site, though they could understand my dilemma, on knowing about this rare gull pairing.

The photo that I've added, is my best bet, that these are the chicks concerned.  One thing is for sure, this is the first time, that the unusual pairing, have nested successfully, after the third year in a row.

Security, did not mind me using the main car park, to scope some of the other gulls on the warehouse roof.  Most were Lesser Black-backed Gulls, a couple of pairs of Common Gulls and a pair of Herring Gulls.  One of the Common Gulls, was ringed with an 'Upside-down' metal ring.  Taking numerous photos, all I was able to capture on the ring was   ES66*** .

Saturday 14th July 2018

Today, I visited Antrim, before driving on down to Belfast, where I called into several sites looking for rings.

Random visits to Antrim Marina, has been very disappointing this summer, with few Black-headed Gulls present during my visits.  I had hoped to record the resident 'ringed birds', especially those that were ringed last winter, as I wanted to ascertain, which were residents.  One of those twelve newly rung birds - 2CSL, had been spotted in north-east Poland, on the 29th March 2018.

Today, numbers of Black-headed Gull, had increased significantly at the Marina, with many of them, no doubt, having completed their breeding attempts for the summer.  Several fledged youngsters, were also on site and over the next few weeks, many more will arrive to choose the Marina, as their wintering site.

Despite the increase, only four 'colour-ringed' BHGs, from Adam's Northern Ireland Study, were recorded -   2ADJ ,   2AAP ,   2CSS   and   2AAT .    2CSS , was one of the gulls ringed last winter and may possibly have summered in the area.  At the time of ringing, it was recorded as a first winter bird, and might well have been reared locally.

We're only a few weeks away, from the start of my sixth winter of 'Ring Watching' at Antrim Marina, which entails at least one weekly visit, usually on Sunday's.  Beginning on the first Sunday in August, until the last Sunday in March, I now have an excellent record of the 'ringed' gulls coming and going.  All these sightings are entered onto a spreadsheet, which now looks very impressive.

Also on today's visit, I recorded my second sighting this summer, of Common Gull -   2AJP .  This is the third summer in a row, that   2AJP , has been recorded here and presumably nested on the nearby 'Torpedo Platform'.

After leaving Antrim Marina, I drove across Antrim Town, to the local Kentucky Fried Chicken outlet.  Here, I was hoping to record   2ADD , from Adam's Study.  This is a gull, we know winters in the coastal County Antrim town of Carrickfergus.  Usually,   2ADD , appears at the KFC outlet before moving on to Antrim Marina to breed at the nearby colony, and afterwards, would reappear at the KFC outlet, before returning to Carrickfergus.

  2ADD , arrived early this year to the KFC outlet, having been recorded on the 29th January 2018.  I last saw it at the outlet on the 19th March, and assumed it had moved on to the Marina, where I've failed to record it's presence.  Now that the breeding season is all but over, there was still no sign of   2ADD   today.  Around 50 Black-headed Gulls were present, which included three juveniles.

However, what really got my attention here, was the presence of two Mediterranean Gulls.  A relatively new breeding species to Northern Ireland, sightings of this species are becoming more common and nesting attempts also appear to be increasing.

Despite checking out several sites in Belfast, looking for rings, the only one found was at Whitehouse Lagoon.  It was one of Adam's birds, Black-headed Gull -   2CNH .  This was the first re-sighting, since the bird was ringed as a chick, on the 16th June 2017.  The ringing site, was Blue Circle Island, on Larne Lough, which is just a few kilometres to the north.

Ailsa Craig - 16th July 2018

I recently joined a boat trip to Ailsa Craig in Scotland.  Having been there twice in the past, I was lured onto this trip, by the promise of a three hour stay on the island.  The previous trips I went on, lacked island time, which meant I did not have much time to explore the nesting birds or check for rings.

Eleven of us, turned up for the trip, with the surprise arrival of my ringing trainers, John Clarke and Ken Perry.  We got our three hours on the island, and nearing the time of the 6.15pm return departure, most were already back at the boat.  At the time, I was making my way back, when John phoned me, to see how I was doing.  Replying, that I would arrive in the next five to ten minutes, John informed me, that there was a 'metal-ringed' Common Gull, near the pier.

John, had failed to catch any details on the ring with his camera, and suggested, I should have a go.  Apparently, the gull had a chick or chicks nearby, but we did not have time to look for these.  This was perfect for me, as the gull did allow close approach and numerous photos of the bird and it's ring were taken.  I decided, I would have enough to complete the ring number, at which point, we embarked onto the boat for home.

John and I, then looked through the photos, and to our delight, we had completed the whole ring number -   ES44995 .  Returning home, I edited the photos and checked the number against others on my spreadsheet.  Emailing the photos to John, Ken and Jim Wells, who organised the trip, I suggested the gull would have been rung in or around 2005.  I reported my sighting through the BTO's new ringing database DemOn.

A couple of day's later, the ringing details arrived back, and what a surprise I received.    ES44995 , had become the oldest British-rung Common Gull, on my records.  It was ringed as a chick, on the 4th June 1999, on Sanda Island, situated 30km away from Ailsa.  The duration read, 19 years, 1 month and 12 days, since being ringed.

The oldest Common Gull, that I have recorded, is still the Finnish-rung   ST177.028 , ringed as a juvenile, on the 6th August 1995, and last seen on March 19th 2018, at Antrim Marina.

Shortly before securing the ring number of   ES44995 , I had come across a Shag, bearing a 'metal-ring'.  The Shag's, being quite nervy birds, would quickly enter the sea, so I was fortunate to capture what I thought was a 'partial number' -   13349** .  As John and I, checked the photos, on our return, we noticed that there were numbers on the top row of the ring, where normally, a reporting address would be  placed.

To me, the ring was unusual, so I emailed the BTO's Bridget Griffen, with photos attached, to see if she knew anything about the ring.  In no time at all, Bridget replied, to say that the top row of numbers -   4908 , were actually the final digits of the whole ring number.  The seven digit number is repeated on both the top and bottom rows of the ring, though staggered.  My initial 'partial ring', reading, was now a full number -   1334908 .

I entered the number on the BTO's DemOn Database, to learn that the Shag, had been ringed as a chick, by members of the Clyde Ringing Group, at Ailsa Craig, on the 6th June 2013.

Having tried to read Shag rings, at Drains Bay, Co. Antrim, the Ailsa bird, was my first successfully read ring for this species.  Three 'metal' rings were spotted on Lesser Black-backed Gulls and another one on a Herring Gull.  As their chicks had already fledged, these gulls would not allow close approach.  A good sized mixed colony of these gulls, nest along the shoreline to the west of the pier.

I came across several Shag nests, situated amongst the boulders below the cliffs.  Containing, one to three large chicks, these had me intrigued and I set about looking for as many as possible.  I must have found around 50 nests still occupied, and many others now empty, as their chicks had fledged.  I did not have time, to check out the east side of the island from the pier.

All these nests had me wondering.  It would be great to start a 'colour-ringing' project on Ailsa's Shags, as so many nests are accessible.  This is something I will check out over the winter months, working out costs and permissions needed.  The island, is a nature reserve, looked after by the Royal Society for the Protection of Birds.

The Gannet colony on the island, exceeds 35,000 nesting pairs, which I believe, is the third largest colony in the British Isles.  I couldn't resist the temptation, to scramble up to a Gannets nest to take a photo of a chick.

While searching for Shag nests, I came across one boulder, that was being used by a gull, as a dinner table.  As can be seen by the photo, the gull concerned is apt at raiding nests and plundering eggs.

Normally, a pair of Peregrines, nest on the west cliff, just before the start of the Gannet colony.  I kept an eye out for Peregrine's, but none were spotted.  This was the result that Jim Wells had observed, over several visits to the island.  It looks, as if no grines are present this year.

I did come across a used Raven nest.  It was on the same cliff site, where I had seen the nest in the past.  It is situated, on a narrow vent, where the rock is horizontal.  Funny thing is, we know Ravens nest here, but I've yet to spot one, during my three visits.

Gulls At Work

Recently, the number of Lesser Black-backed Gulls, at my place of work, has been increasing.  In the last couple of weeks, I started to go to work slightly earlier, which would give me around 30 minutes to scope the birds for rings.  I always believe, that if you check a site long enough, you'll always fall in with a ring sometime or other.

I work, Monday to Friday evenings, now staring at 6.30pm.  On the first Friday of 'Ring Watching', I spotted a Lesser Black-backed, with a 'metal-ring'.  It was of no use to me, due to the distance from the car park and the factory roof.

The following Friday (20th July), success.  I spotted a bird, with a black ring.  Moments later, I captured the code   F59C .  I knew straight away, that this gull had been ringed in Portugal.  In the past, I've recorded   F461 , at Whiteabbey, which I believe, was the first record of a Portuguese-rung, Lesser Black-backed Gull, spotted in Northern Ireland.  Cameron Moore, recorded a second bird -   F633 , at Whitehead, these sites being situated on the east County Antrim coast.

I reported my sighting to RIAS, an animal rehabilitation centre at Quinta de Marim, Olhäo, on the southern coast of Portugal.  The ringing details arrived back, to say, that this 3rd Calendar year bird, was ringed on the 6th March 2018.  I've worked out the distance, as being roughly 1,986 kms / 1,234 miles, in a northerly direction.

  F59C , now overtakes   F461 , as my longest distance ring sighting, albeit, just by a few kilometres.

Saturday 21st July 2018

Lured by my recent Common Gull sightings at Millisle, I decided to take myself off there today and have another go.  A second reason for a visit, was to see how well, I could encourage the gulls to approach me to be captured for ringing.  The BTO, have recently granted my request to catch and ring adult Common and Black-headed Gulls.

Some of the 'colour-ringed' Common Gulls at Millisle, have rings that are clearly disintergrating and in need of urgent replacement, and I would love to catch several 'metal-rung' birds and fit them will a colour-ring, as well as those with no rings at all.  I came to the conclusion, that a small number could well be caught by hand, though a trap or net, would be needed.

On my way to Millisle, I stopped by Whitehouse Lagoon on the outskirts of Belfast.  The only ring spotted was on a Black-headed Gull, feeding a chick.  Returning home, later on Saturday, I checked the ring -   2AHJ , against my spreadsheet.  What an interesting sighting, this one turned out to be.

On the 27th May and 24th June 2018, I recorded   2AHJ , in the breeding colony at the Castle Espie Wetland Centre, in County Down.  Ringed as an adult male, at Castle Espie, in March 2013,   2AHJ , has a quite lengthy history of re-sightings at Castle Espie.

Today's sighting of the bird at Whitehouse Lagoon, was the first record away from the Wetland Centre.  It's a pity, that Adam did not get round to ringing chicks at Castle Espie this summer, as I could have had a photo of a 'ring, feeding a ring'.

At Millisle, there were far too many people around, to try and catch Common Gulls or even try to read 'metal-rings', bar that of one gull in particular.  I had to settle myself, to reading colour-rings, with four sightings, all of gulls recorded in the last few weeks -   2BBC ,   2ADX ,   2ANJ   and   2ACA   (last seen at Donaghadee).

Moving on to the southern car park at Millisle beach, I caught a glimpse of a Common Gull, with a Blue ring, starting with the letters   2H** .  Immediately, I knew this would possibly be a new sighting, but a car drove by, sending the gulls into the air and off to the beach.

I  drove back round to the northern car park and waited.  The incoming tide, was pushing the gulls towards me and I began throwing out bits of bread to lure the gulls in.  Eventually, my new sighting landed in front of the car, and a few photos later, the code was captured -   2HSH .

Returning home, I checked the code, with the records that I received from Shane Wolsey, after I took over his Common Gull Project.    2HSH , was ringed as a chick, on the 10th June 2011, on Big Copeland Island, 8 kms to the north.  The only previous sighting, was at Millisle, on the 30th July 2013, when the gull was spotted by Adam McClure.  The duration since ringing, is now 7 years, 1 month and 11 days.

The only 'metal-rung' gull, that I took an interest in, was the Norwegian bird, recently re-sighted here on the 29th June 2018.  On that occasion, I only managed to obtain a 'partial number' -   ***2366 , but reckoned it was the same bird recorded the previous year, on the 14th July 2017.  I reported the sighting to Norway, stating a partial number and my belief that it was   5182366 , and they accepted my sighting.

Today, I had no trouble, in recording the number and indeed it is   5182366 .  I would really love to 'colour-ring' this bird, as it would be easier spotted on it's return to Norway.  I have sent another email to Norway, with the latest photo attached.

Leaving Millisle, I decided to finish off the afternoon, with quick visits to Ballywalter and Portavogie.  At Ballywater, I was on the lookout for my oldest Black-headed Gull -   ET02500 .  This bird, having been ringed as a chick, had a duration of 19 years, 6 months and 18 days, when last seen on the 23rd December 2017.

Previously, I've recorded the gull on five occasions, which included July sightings in 2016 (16th) and 2017 (30th).  Around 50 Black-headed Gulls, were around Ballywalter Harbour, but no sign of the bird I was looking for.

A Common Gull, landed briefly, which bore an 'upside-down' metal ring.  All the gulls took to the air, as a young couple, along with their dog approached.  I only managed a couple of photos, but all I got of the ring number, were the final three digits -   989 .  After the couple moved on, I lured the gulls back in with bread, but the Common Gull, did not return.

There were loads of large gulls at Portavogie Harbour, especially immature birds.  Most were lying about rooftops and even the lure of bread, did not persuade many to budge.  I still managed to check out over a hundred pairs of legs, but no more rings.

Rings & Shearwatering...

Common Gull Ringing - Rathlin Island & Ballintoy Harbour

Common Gull ringing this summer, was concentrated at my main site of Rathlin Island, just off the north coast of County Antrim.  First visits to ring chicks, were made on Monday 18th June and Tuesday 19th June, followed by second visits on Monday 25th and Tuesday 26th June.

I was accompanied, by my sister Heather, on the 18th & 25th June, and my eldest son's mate Michael Wright on the 18th.  My thanks to them both, helping me to locate chicks and writing down the ringing details.

Altogether, 69 chicks were ringed with 'metal-rings', with 53 also being large enough to accept a 'colour-ring'.

Searching for the youngsters, was a tough job.  Breeding success this summer appears to be worse than last year.  The Common Gulls nest in loose colonies, on an extensive rocky shoreline, between the east and south lighthouses, as well as, a small colony on the western shore of Roonivoolin and on the freshwater Lough Ushet.

Not only have the gulls suffered from heavy predation, by the same two pairs of Great Black-backed Gulls, which were also present last summer, but a large number of eggs were located by Heather, Michael and myself, which had been 'holed', possibly the work of Hooded Crows or Ravens.

Another factor, may have been the weather.  The 'Beast from the East', which brought in wintery conditions at the commencement of the breeding season and more recently 'Storm Hector', on the 14th June, with it's gale force winds and heavy downpours, all contributed to the poor output of youngsters.

I reported my ringing efforts to Ric Else & Hazel Watson, editors of last year's first ever Rathlin Bird Report (see side bar).  Ric, was in complete agreement, about my observations and had noticed a lack of chicks at Rue Point, where the Common Gulls normally nest in good numbers.

Two fully feathered chicks, which had been 'colour-ringed' on the 18th June, were found on the 25th, having been recently killed and eaten.  I removed their 'colour-rings', which were re-fitted onto other chicks on the 26th.

Last year, I learned of the presence of a Common Gull colony at Ballintoy Harbour, which was brought to my attention by Richard Donaghey.  On checking it out, I found a few fully feathered chicks, which were about ready to take flight.

I completed a small number of visits to the harbour at the start of this year's breeding season and around a dozen pairs of Common Gulls were on site.  One of the reasons, for my pre-season visit, was to see if I could locate an adult with a 'Blue-Darvic', which Richard had spotted.  The gull in question, was never found.

The Common Gulls at Ballintoy Harbour, also appear to have had a poor breeding season.  Although, predators, do not seem to be a problem, the area is swamped daily by fans of a 'hit TV series'.  The scenic Ballintoy Harbour, was used as a setting, for the 'Game of Thrones'.  Coachloads of people arrive, with many folk clambering around the rocks were some of the gulls nest.

This summer, there was no doubt, that the visitors have had their impact on breeding success.  Only three chicks were located.  One was on a rocky islet, surrounded by the sea.  One was discovered on the sea, perhaps taking refuge from the vistors and I managed to catch and ring a third well feathered chick, on the shore in front of the cafe.  I reckon this one, had been forced onto the sea, but had swam ashore.

I have avoided the colonies at Torr Head on the east coast of County Antrim and the moorland colony at Lough Galboly, high up on Antrim's Garron Plateau.  My recent shoulder problems, would prevent me climbing down to reach the island at Torr Head and I would guess that the small colony on Galboly, would have suffered from the weather.  I might still check this site shortly, as they will be late nesters, much like the Common Gulls at Waterfoot, where I'm currently watching for chicks, as the adults there are alarm calling.  Chicks were ringed at Waterfoot, on the 10th July, last year.

Millisle, Donaghadee & The Copeland Islands

On Friday the 29th June, I set off on an eagerly awaited, first ever trip to the Copeland Bird Obsevatory, on the Copeland Islands in County Down.  Over the last few years, I've recorded many ringed birds from the Copelands, so it was great to actually visit the place.  I would be staying for the weekend, returning late on Sunday afternoon.

With the boat having to make two trips out, I was booked onto the second boat, leaving at 6.30 in the early evening.  Having to get through Belfast, to reach County Down, I decided to get down there very early and avoid the rush hour traffic in the city.  Should a car accident occur during the rush hour period, Belfast can become grid locked very quickly and I did not want to get stuck in the middle of that.

Safely through Belfast, I reached Millisle at 3.30 and decided to get my dinner there, namely, a sausage supper.  With dinner in hand, I drove around to the seafront, where the Common Gulls would gather.  I had planned to carry out a bit of 'Ring Reading', before making my way to Donaghadee to catch the boat.  With the tide on it's way out, I wasn't disappointed, with plenty of gulls about.

Using the remains of my dinner, I used these bits of chips to lure the gulls towards me.  In no time at all, I recorded six Common Gulls with 'colour-rings' and had a partial number on a 'metal-ring' for a seventh bird.  This 'metal-rung' bird, was of special interest, as I could see the word - Norway.  Unfortunately, the gull flew off and did not return.  All I had of the ring number was   ***2366 .

I immediately suspected, that this was the same gull, that I spotted here last summer (14th July 2017), in it's juvenile plumage.  The only problem, was that I would have to wait till Sunday evening, to check on the ring number.  When I did return home, this was my first task and I was right, the gull was   5182366 .  Despite, having secured a partial number, there can be no doubt, this had to be the same gull.

I have since reported my sighting to Norway, complete with photos, and now await their reply.  There shouldn't really be a problem with this one.    5182366 , was ringed as a chick, on the 9th July 2016, in the Karmøy area of southern Norway.  The distance to Millisle, is 835 kms / 518 miles (SW) and the duration since ringing is now 1 year, 11 months and 20 days.

It would appear, as if   5182366 , is fond of Millisle, so there's every chance that this gull may be recorded here again in the future.

On Thursday the 5th July, an email arrived from Stavanger Museum, in Norway.  My partially read ring number, was accepted as being that of Common Gull    5182366 .

Another gull I was pleased to spot, was my sixth sighting of   2ABF .  Ringed as a breeding adult, on the 14th May 2010, it's first re-sighting was made on the 23rd January 2016, when I spotted it here at Millisle.  My fifth and last sighting of   2ABF , was made on the 14th July 2017, but David Nixon reported his sighting of the gull to me, on the 23rd November 2017.  Glad to see, that it is still going strong, the duration since ringing, now 8 years, 1 month and 15 days.    2ABF , has yet to be recorded away from Millisle.

The rare sighting of another Common Gull, was that of   2ALN .  Ringed as a chick, on the 18th June 2012, today's sighting, is only the second record of the gull since being 'colour-ringed'.  I first came across   2ALN , on the 14th July 2017, at the other end of Millisle beach.  It is now 6 years and 11 days, since   2ALN , was ringed on the nearby Copeland Islands.

  2ANA , was still present at Millisle today.  Ringed as a chick, on the 27th June 2014, it had gone unrecorded until recently, when I spotted it here, on the 16th June 2018.  I called into Millisle last Sunday (24th June), after visiting Castle Espie and   2ANA   was present then as well.  Thats three sightings now altogether.  It's duration since ringing, now tops the 4 year mark, at 4 years and 2 days.

Common Gull   2ANJ , was also spotted for the third time in recent weeks (16th & 24th June).  Ringed as a chick, on the 11th June 2012, it was re-sighted twice at Millisle, the following year by Adam McClure (Jul & Oct 2013).    2ANJ , was not spotted after that, until I recorded it, for three months in a row in 2016 (Jul, Aug & Sep).  There were no sightings in 2017 and the duration since being ringed, is now 6 years and 18 days.

Leaving Millisle, I drove the short distance to Donaghadee Harbour, where I was to meet the boat for the Copelands.  It took a while to find a parking spot on the seafront, and then I walked up to the harbour.  A group of people, were gathered along the harbour wall, and I asked if they were for the Bird Observatory, which was confirmed.

They were booked on the first boat out, whilst I was due to leave on the second boat.  As it turned out, these folk, were from the Conservation Volunteers and their task was to cut back the paths that criss-cross Lighthouse Island, where the Observatory was situated.

I walked back to my car, to collect my gear and just wait for my turn out on the boat.  Glancing at the gulls on the local rooftops, I noticed a Common Gull, which I thought was ringed.  Zooming in, I took a couple of photos and discovered that I had spotted   2ACA .  This was my 11th sighting of this gull and it was the first record of it away from Millisle, albeit, just a couple of miles up the coast.

I recorded   2ACA , at Millisle, thirteen days ago.  Ringed as a breeding adult in May 2010, the duration since ringing, rises to 8 years, 1 month and 15 days.

Copeland Bird Observatory

At last, I have finally visited the Copeland Islands, for my very first time.  Over the last few years, I've recorded many birds that have been ringed here, but it was brilliant to actually be on one of the three islands.  Having become a member of Copeland Bird Observatory, I was able to take advantage of a weekend stay on Lighthouse Island, where the Observatory is situated.

Lighthouse Island, is the site of the former lighthouse, the modern lighthouse being Mew Island, which is sited across a short stretch of sea.  Both of these islands, lie to the north of Big Island, which we passed by on the boat to reach the Observatory.  Looking at the number of gulls on Big Island, is appealing, for a visit there as well.

I had hoped to visit the Observatory, on the weekend of the 22nd to 24th June, to ring some Common Gull chicks, but a 'Duty Officer', was not available.  This weekend's stay (29th June to 1st July), was led 'Wes', Wesley Smyth.  As most Common Gull chicks, would have been too large to catch and ring, I decided to check out the island for a spot of 'Ring Reading' instead.

During my time on the island, I checked out hundreds and hundreds of pairs of gull legs looking for rings.  Not a single 'colour-ringed' gull was found, which I found surprising.  With 'colour-ringing' projects on the Isle of Man and Ayrshire in Scotland, I would have thought that some of their young gulls could have re-located to breed on the Copelands.

Even 'metal-ringed' birds were difficult to find on Lighthouse Island, but I did find three Lesser Black-backed Gulls and two Oystercatchers that had 'metals'.  My task now, was to capture the details with my camera.

The first 'metal-rung' Lesser Black-backed Gull, was not very obliging.  Each time it took off and landed, I kept getting the same partial number on it's ring -   0021 .  Having tried for about 30 minutes, I decided to move on, as some gulls that were disturbed by my presence were still incubating eggs or small chicks.  Despite the warm conditions, it was only right to let the birds settle again for a while.

I tried on two other occasions to complete the number, but I could not find the gull again.  Anyhow, looking at what I had, I suspect that the slightly worn ring, could belong to the   GA00***   series, which would mean, my Lesser Black-backed, could be rung   GA0021* .  At present, I have a Herring Gull at Millisle, which is rung   GA00153 , and both it and my current gull, have their rings fitted 'Upside-down'.    GA00153 , was ringed as a chick in 2005.

The next 'metal-rung' Lesser Black-backed Gull, was more accommodating.  With at least one large chick, I was able to get quite close to the gull and with me standing up and sitting down again, the gull would fly up and land, according to my movements.  This gave me the opportunity, to take lots of photos of the ring.

After a short period of time, I moved away and checked my pictures.  I was pleased to find, that I had captured the whole ring number -   GR11491 .  After I returned home from my weekend trip, I reported the gull on the BTO's DemOn, and the ringing details arrived a few days later.

  GR11491 , had been caught and ringed as an adult male, on the 8th June 2013, on the Copeland Islands.  It was 5 years and 22 days, since the gull was ringed and this was the first re-sighting, which is not really surprising for a 'metal-rung' gull.  One good thing about trying to read 'metals', is that the birds don't fly off on you, when they have eggs or young.

A 3rd 'metal-rung' Lesser Black-backed Gull, was located close to the back of the Observatory buildings.  On each of the three occasions I saw the bird, it just flew off, which makes me think, that it had failed in it's breeding attempt.  There was no reaction from the gull, so I reckon it was just standing guard over it's nest site.  Perhaps I'll get this one next year.

Two 'metal-rung' Oystercatchers were also located, and the ring numbers were completed for both.  One of these turned out to be quite interesting.  The 'standout' feature of it's ring, was a large gap between the 'ring butts', which suggested that the bird was not ringed properly.

Having taken lots of photos over the course of three visits, I was convinced, that I would have the whole ring number, then I wasn't so sure.  This female Oystercatcher, had a single egg, which is very late into the season and may well have been a replacement clutch.  I had to make short visits, so she could get back to her nest.

With three sets of photos, taken over the three visits, I kept coming up with an incomplete number -   FC7612 , but wondered where the missing digit would be placed.  Checking the numerals, under the address line above, I realised that the gap in the ring, was caused by a break, which had held the final digit and on the address line the end of '  LONDON SW7 ', was also missing.

Now knowing the ring number was   FC7612* , I sent a copy of my photos to the BTO's Ringing Department, in the hope they could still generate a recovery for this quite old ring.  As it turns out, the number is not on their computer system, but would be on an old 'paper schedual', but they were unwilling to look for it.

I also informed Chris Acheson, who holds all of the Observatory Ringing Data, but he was in France on holiday, and would check the number on his return.  Off hand, I think   FC7612* , may have been ringed 20 years ago, in 1998.  I found   FC76151 , on the BTO's DemOn Ringing Database, and it belonged to an Oystercather, ringed on the 11th July 1998, as a juvenile.

(Ringing Details to be Resolved)

The second 'metal-rung' Oystercatcher, gave me the 'runaround' trying to obtain it's ring number.  With two fully fledged youngsters, it and it's offspring, wouldn't hang around for photos.  After three attempts, I did finally obtain the full number -   SS42626 .

With the number being quite recent, the Duty Officer - Wesley, told me where I could find the 2018 ringing log.  Sure enough,   SS42626 , was listed, and had been ringed as an un-sexed adult, 22 days earlier, close to where I spotted the bird.  No excitement here, but at least the ring was read.

After mid-night, on both Friday & Saturday, some of us helped Wes, to locate and catch Manx Shearwaters.  These birds return to their nests burrows during the night, to feed their partners or chicks.  It was quite an experience, doing this for the first time.

Over the two nights, a number of birds were caught, with quite a few 'retraps' being made.  About a third of all birds caught, were unringed and these were then marked by a trainee ringer.  I'm hopeless with names, but for all those that spent the weekend on the island, I say 'Hi', even though I did not get a chance to talk to everyone.  A thoroughrly enjoyable weekend and I look forwards to my next visit.
