Eagles Re-Visited...

At present, my blog is being somewhat neglected.  This is a busy time of the year for me, as whenever possible, I'm out checking raptor nests, and ringing seabird chicks.  More about these in my next post, but the highlight of recent activities, was to re-visit the two eagle nests in Scotland.

      Saturday 15th June 2019       
Today I did both, a bit of 'Ring Reading' and checked on a couple of Peregrine Falcon nests.  First stop, was at the RSPB's Window on Wildlife Reserve in Belfast, before making my way up the County Antrim coast, to finish the afternoon at Carnlough Bay.

At the WoW Reserve, I had hoped to record some of Adam McClure's Black-headed Gulls, with the 'Orange Darvics' and have another go at completing the 'metal number' on a Mediterranean Gull.  Since my previous visit, the Tern nesting platform has been floated out into position, this being located at a totally ridiculous area of the lagoon, where viewing is practically a non starter.

Last summer, three Tern platforms were put out, two of which gave reasonably good views of these birds nesting.  This year, I think the management has been poorly thought out.  The single extended platform, was in my opinion, far too late, in being positioned.  

Another bit of poor planning, was the siting of the new nestboxes, on the ground at the far side of the lagoon.  With all of the rain that we have experienced over the past number of weeks, some of the nestboxes were clearly flooded, which would have resulted in some clutches of eggs being lost.  I reckon the RSPB, will have to totally rethink their plans for next year.

As for the two main nesting platforms, which were initially intended for the Terns, they are always hijacked each year by the earlier nesting Black-headed Gulls.  Today, both platforms were crowded by fully feathered BHG chicks, plus there were plenty of fledged youngsters either dotted around the shoreline, or floating on the lagoon itself.  Both platforms, are also heavily overgrown with vegetation, thus making 'Ring Reading' near impossible.

Of the five pairs of Med Gulls which nested on platform 2, the earliest breeding pair have gone.  When I last saw them, they had a single quite well feathered chick, which I would assume did fledge successfully.  Just the one Med Gull chick was seen during my visit belonging to a pair which nested close to the pair mentioned above.

The French 'colour-ringed' Med Gull is still present, courtesy of a recent email from James McDowell & Hill Dick, but it is nesting at the far back of the platform, and is totally hidden by vegetation.  The other two pairs of Med Gulls, though nesting towards the front of the platform, are still present but are also near totally hidden by plant growth.  This would include the 'metal-rung' bird, who's complete number, has yet to be completed.

Having come up blank at platform 2, I then went to the visitor centre to view platform 1.  Again, the platform was covered in tall vegetation, therefore many legs were hidden from view.  This platform was also heavily populated with fully feathered Black-headed Gull chicks.

On the grass in front of the visitor centre, a Tern was sitting on a nest in the middle of a small circle of stones.  Earlier in the summer (20th April), a 'metal-rung' Black-headed Gull -   EZ33143 , had built a nest on this very same spot.  This gull, which was ringed as a chick, in South Lanarkshire, Scotland, was not even two years old, therefore it went through the motions of breeding, but disappeared soon afterwards.

Watching this nesting Tern, it's partner arrived and this bird was fitted with a 'metal-ring'.  I thought great, as they were near enough, that I might be able to catch the number with my camera.  To my amusement, when the pair swapped over nest duties, it turned out that both birds are ringed with 'metals'.  The birds can be individually identified, as one has a darker tip to it's beak, so the challenge at some point, is to try and capture the number for both birds.  This should be easier, once the eggs hatch.

A 'metal-rung' Black-headed Gull landed briefly in front of me.  I'm glad I zoomed in for the 'metal' before taking a photo of the bird itself, as it took off and was not seen again.  At home, I checked the partial number -   EZ281** , against my spreadsheet, to find I had a match to the ring series.  On the 18th December 2017, I recorded   EZ28165 , a bird which was ringed as a chick, in June 2015, in Flintshire, Wales.  Without the full number of today's sighting, it could possibly be that very same gull, or perhaps another one from Wales.  The December sighting, was at the former Belfast Waterworks.

On leaving the RSPB WoW Reserve, I checked several small flocks of gulls on the coast for rings without joy.  Once I reached the small town of Whitehead, I checked out the Peregrine site at the Blagh Hole, which is probably Northern Irelands best known pair.  On my last visit here, the female was sitting on eggs.  Today, three fledged chicks were seen together at the cliff top.  The site is well watched by folk out for a stroll, passing by the nest-site on a constant basis.

Three Fledged Peregrine Falcon Chicks  (15 Jun 2019)

The second Peregrine site that I called by, was the same one that was featured in my previous post.  Having sent Jim Wells photos, showing the location of the nest ledge, he visited the site four days later (12th June), and eventually made a head count of three very large youngsters.

I spent a good hour here today, but there was very little activity on the ledge, with just two chicks being counted.  It was getting so late in the day, the young were probably well fed and just lazing about.  The photo shows a chick on the left which was stretching, hence the fanned tail, with the second bird immediately beside it, to the right.  All three should take flight at some point over the next few days.

Two of Three Peregrine Chicks Which Were Visible  (15 Jun 2019)

Continuing to check small flocks of gulls for rings, I reached Glenarm Harbour, where my focus changed to Black Guillemots.  In the past, I have recorded a 'colour-ringed' bird here, but failed to re-sight it last summer, having recorded it, during the three previous summers.

There was not a lot of activity among the Guillemots, where many pairs nest in holes in the harbour wall.  There will still be plenty of time to check these birds, as they should have small chicks, and July will be time enough to have another go, to see if I can re-sight -   FT .

Finishing off the afternoon at Carnlough Bay, there was a good gathering of Great Black-backed, Lesser Black-backed and Herring Gulls.  Scoping through these, I finally got my first confirmed ring sighting of the day.  This belonged to an immature Great Black-backed Gull, and I immediately recognised the code -   X:065 .  My first sighting of this bird, was made earlier this year (17th March 2019), at Glynn, on Larne Lough, which is a few miles south from Carnlough.

Ringed as a chick, in June 2017, in the Isle of May, Scotland, it's only other sighting prior to those I made, came way back in November 2017.  On the 15th November, David Nixon, spotted the bird at Millquarter Bay, in County Down.  The distance from the Isle of May (Rona), to Carnlough, is 253 kms / 157 miles (WSW).

      Rathlin Island - 16th and 18th June 2019       
This week saw the start of several visits to Rathlin Island, to 'ring' or 'colour-ring' Common Gull chicks, for my own project, which began in the summer of 2017.  My aim is to 'colour-ring' chicks in County Antrim, with the main emphasis being placed on the small breeding population on Rathlin.

Prior to the start of my project, 4 Common Gull chicks were 'metal' rung in 2016 - 2 on Rathlin and 2 at Waterfoot.  In 2017, 36 chicks were 'colour-ringed' on Rathlin, plus 2 more at Waterfoot.  In addition to these, 4 chicks on Rathlin, were ringed with 'metals' only.

Last year - 2018, 53 chicks were 'colour-ringed' on Rathlin, plus 1 at Ballintoy, and 1 at Waterfoot.  On Rathlin, a further 16 chicks, were ringed with 'metals' only.

With the addition of a couple of first re-sightings on my recent visits to Rathlin Island, a total of 10, of the 2017 'colour-ringed' gulls have been recorded back on Rathlin this summer.  This total comes near to a third of the 'colour-ringed' birds that were ringed in 2017, a total which I guess would be the survival rate of youngsters, getting through their first winter alive.  I reckon this is a good 'omen', as there will be others from the 2017 cohort, which are still to make an appearance.

Just one of the 53 'colour-ringed' youngsters from 2018, on Rathlin, has been spotted so far, but this is not unexpected.  At present, I think many of the 2017 rung birds are just prospecting, as they are approaching breeding age now.  Next summer, will see these birds nesting for the first time, whilst the 2018 youngsters will return to prospect future nesting areas.

Looking further ahead, it will be great to record these gulls integrating into the breeding population for years to come.  What I need now, are winter sightings, to learn where our Rathlin birds go to.  Somewhere at present, there are as many as 18 surving immatures from 2018, dotted around our coasts somewhere, just waiting for someone to spot them.

So far this season is looking very bleak for the Common Gulls.  Back in early May, I visited the island, to access the breeding population, and noted a decrease in the number of pairs, in all of the colonies, perhaps excepting Ushet Lough.

My visits on the 16th & 18th June, saw very few chicks being 'colour-ringed'.  On the 16th, just 7 chicks were large enough to take a 'colour-ring', whilst 3 others were ringed with 'metals' only.  Nothing was ringed on Ushet Lough or Roonivoolin.  However, the small island on Ushet, did have 4 chicks, 2 of which were nearly fully feathered.

On the 18th, 3 were 'colour-ringed' at Doon Bay, and a further 8 were 'colour-ringed' at Rue Point.  At Rue Point, another 2 chicks, were ringed with 'metals' only.

At all sites, there were a small number of chicks, that were too young to be rung at all, and hopefully they will survive until my next visits on the 24th & 26th June.  A handful of nests were found containing eggs, but I think for these to get as far as fledging may seem unlikely as it is beginning to get so late into the season.  Overall, I reckon the weather has played a big part in this less than saticfactory season.  The amount of rain that we have had over several weeks, has no doubt killed many of the chicks.

As well as looking for chicks to ring, I scanned all the gulls for 'colour-rings'.  On the 16th, I recorded the first re-sighting of   2AVT , at Arkill Bay, and then spotted the same bird on the 17th, this time at Rue Point.  No doubt, this gull is checking out the island.

Another first re-sighting, among the five 'colour-ringed' gulls that I recorded on the 18th, was   2ATV .  It was at Rue Point, no doubt prospecting for next year.

The next two gulls, were   2AJT   &   2APT , which had already been recorded more than once by Richard Else, who is working with the RSPB, on the island.  These were my first sightings, since I ringed them as chicks, and all sightings were made at Rue Point.

I spotted   2BAJ , at Doon Bay.  This was the bird, whose photo appeared on the NIBA website, and I had to track down the photographer, and where the photo had been taken.  The photographer was Kevin Kirkham-Brown, and the site was Ushet Lough, situated just over the cliff-top, from where I saw the gull today.  Just great to know, I had these birds in my hands as chicks.

Black-headed Gulls
This summer, Black-headed Gulls have nested on Ushet Lough and at Rue Point.  This seemingly follows the collapse of the only known breeding colony at Kebble Lough, situated at the far western end of Rathlin Island.  Richard Else, cannot find the cause of the collapse, but there's no doubting that some of these birds have now re-located.

At both sites, there are nests containing either one or two eggs, and at Ushet Lough, four newly hatched chicks were also seen.  Empty nests, were also present at both sites.  If the birds are about to lay eggs, I do not have much hope in their survival, being so late into the season.  Even those that have eggs and chicks now, will do well if they can raise young to the fledging stage.

Great Black-backed Gull
On a reconnaissance visit to Rathlin in early May, to determine the number of nesting gulls, I located the nest of the Great Black-backed Gulls, on the headland, at the northern end of Doon Bay.  No Great Black-backed's were seen at Arkill Bay, although I suspected they were nesting, but the nest would have been out of sight.  On that particular visit, colonies were viewed from a distance, to try and keep disturbance to a minimum.

On Sunday 16th June, I located a single chick at Arkill Bay, which was just about old enough to take a ring.  No such problem, during my visit to Doon Bay, on Tuesday 18th.  Here, I found three larger youngsters, which were all ringed.  As they were a bit 'flighty', I placed all three onto their backs, while I made my departure.  Being on a headland, I did not want them running off, and possibly falling over the edge.  Placing them onto their backs together, helps to keep them calm.  Eventually, they will sort themselves out, by which time, I'm long gone.

Oystercatcher, Eider Duck and Shelduck
Rathlin Island is covered with nesting Oystercatchers, and I managed to spot chicks at two sites.  At Mill Bay, close to the harbour on Rathlin, two chicks aged around 4 to 6 days old were seen, on the 16th June.  Should they survive by the time of my next visits on the 24th & 26th June, I will attempt to catch and ring them.

Two chicks were also found at Rue Point, on the 18th June.  These were only a day or two old, but I will probably avoid these until the 6th or 7th July, which will more than likely, be my last visit/visits to Rathlin this summer.  If I can re-locate them, I will get them ringed.  The Oystercatchers here are quite used to people, as they walk by to Rue Point Lighthouse, therefore making the chicks easier to find.

The majority of Eider ducks, are now dotted around the shores of the island, with broods ranging from one to five in number.  A few late ducks were found still sitting on nests, on both the 16th and 18th June, at Arkill Bay, Doon Bay and Rue Point.

The only brood of Shelducks, was spotted on the 18th June at Doon Bay.  This brood contained a massive 12 youngsters, which, if I can remember correctly, would be the largest I have ever seen for this species.   

Greylag Geese
On the sea at Doon Bay, several pairs of Greylag Geese, were gathered along with their broods, which ranged in number from 2 to 5 youngsters.  Ushet Lough, holds large numbers of non breeding Greylags, but one brood of 7 chicks were also present.  Looking through the Greylags with my binoculars, two were spotted with Orange Neck Collars.

Camera out, I soon captured the codes on both collars, which read   B|VI   &   B|VJ .  I made my first ever sighting of these two last summer, during my visit to Ushet Lough, on the 18th June 2018.  Today's sighting on the 16th June, is just two days short of a year, since I last saw them.  These two are a pair, the female being   B|VI  , and were caught and ringed at the same time, at Church Bay, Rathlin, on the 10th February 2017.  It was good to record them again.

Peregrine Falcon
Whilst checking out the Common Gull colony at Roonivoolin, from the cliff top, I also scanned the cliffs with my binoculars, looking for the possibility of Peregrine Falcons.  Away in the distance, I spotted the unmistakable white breast of a bird perched on a rocky buttress.

Moving slightly inland, so as not to be seen, I made my way along to the cliff in question.  Looking over the cliff top, both adults began alarm calling, so I had a definite nest somewhere.  It took around five minutes to locate the nest ledge, which contained two near fully feathered chicks.

I sent a text message to Jim Wells, to inform him of my sitghting, and the reply was 'Great News', this was the first time in around five years since the Peregrines had last nested on these cliffs.  Apparently, they were here last summer, and either did not breed, or failed early into the season.

Jim, has followed the Northern Ireland Peregrine population, since the late 70's, and has a good knowledge, as to how the birds fare here.  He also has a good record for all the breeding sites, with full breeding histories for most of them.

      Inch Island, Co. Donegal - 19th June 2019       
Our second visit to Inch Island Lake, took place on Wednesday 19th June 2019.  Unlike the previous visit, there had been showers of rain, and as we were in the boat making our way over to the island, we were hit with yet another burst of rain.  Once on the island, we had a dry hour to ring chicks.

Whilst the others were busy looking for and ringing Sandwich Tern chicks, I was left on my own, ringing the Black-headed Gull youngsters.  All around the island, there were many chicks lying dead with the recent poor weather, the most likely cause of deaths.  Once again, I selected only the largest chicks for ringing, but only 26 were 'colour-ringed', by the time the hour was up.

On the previous visit, 28 chicks were 'colour-ringed', but two of them were also found dead.  I removed their 'colour-rings', which can be used another time.  This leaves my overall total for the two visits, at 52 'colour-ringed' youngsters.  Lots of fully feathered chicks, stood around the water's edge, but it was wiser to stay clear of them, so as not to force them out onto the water.  Again, many could have been ringed with 'metals' only, but in reality, this would have been a waste of time and money.

The Sandwich Tern team, 'metal' rung a further 68 chicks, which added to the 189 which were 'metal' rung on our first visit, resulted in a total of 257 chicks altogether.  This year, some of the 'Sannie Tern' chicks, were being ringed with 'colour-rings' for the first time at this site.  22 young birds were 'colour-ringed' today, which took the overall total for the two visits to 30.  Ken, located and ringed 14 Common Tern chicks, with 'metals', and a further 5 'metals', were used by trainees on Black-headed Gull chicks.

No further visits are going to be undertaken, as barring the Common Tern chicks, most of the other birds are close to finishing their nesting season.  Hopefully, we will hear about some of our 'colour-ringed' youngsters in the future.  Again, many thanks goes to Lee McDaid and Martin Burke, rangers with the Irish National Parks and Wildlife Service, who supplied the boat and their excellent service.


      Return to Scotland - 22nd June 2019       
Today, we returned to Scotland to re-visit the two eagle nests we saw on the 22nd May.  We had planned to return on Wednesday 26th June, but the date was brought forward by the request of the boatman, Charles Stewart.  Even the departure time of 10am, was changed to 9am, which really did not suit me at all.  Having finished work at 2am in the morning, I got to bed at 3.30, and was up again at 7.15.

Going to the Isle of Jura first, we located a pair of Sea Eagles at a site, which was known, but there were no signs of the pair being present on our previous visit.  Unlike everyone else, I didn't even bother taking photos, but afterwards on receiving emails, it turned out that one of the pair was ringed with a 'colour-ring'.  Just shows, how un-awake I was, not even thinking about that possibility.  This pair in all likelihood, had a nest in the plantation, just inland from the rocky shoreline, on which they perched.

Moving on the the nest we found on our previous visit, a large fully feathered chick could be seen, but unlike last time, it's parents did not appear.  Also, on our previous visit, some thought that there was two chicks in the nest.  Today, with one youngster easily confirmed, there appeared to be a second chick, standing behind the nest, but was near totally obscured by foliage.  In the end, we had to leave, but at least we had one confirmed, and the possibility of a second youngster.

White-tailed Sea Eagle Chick, on it's Nest  -  Isle of Jura, Scotland  (22 Jun 2019)

We moored up, for a near two hour stop, at the village of Craighouse, where everyone could stretch their legs and get a bite to eat.  The smell from the distillery, near put me in the notion for a couple, but with a car to drive, a can or two of beer would have to do me once back at home.  After this, it was straight on to the Isle of Islay, and the Golden Eagle nest.

On arrival, both adults were present, with the female being spotted on the nest.  Last time, the 'jury was out', whether they had a chick or not, but today a chick was spotted.  Everybody but me, were busy taking photos.  I did try, but quickly lost patience, as the boat was bobbing around too much, and by now, some sleep would have appealed to me more.  Matters became a lot more interesting, as a female Merlin appeared on the scene, and tried her best to scare the eagles off from their own nesting cliff.  Some spectacular chases were then witnessed by all.

There's no doubting that the Merlin has a nest of her own, somewhere close by, possibly in the heather of the adjoining hillside.  The eagle chick, is obviously a late youngster, as the head is still white.  Normally, for this time of the year, Golden Eagles should have large fully feathered young.  Despite a very long day out, it was well worth seeing both species of eagle, and a Merlin providing some added entertainment.

Old Bird - New Site...

Another lengthy post, but it has took a while to gather enough info for it.  The weather over the last couple of weeks, has not been great, preventing me from going out when I had some free time.

The publication of this post, could not have come at a better time, as I'll be busy over the next couple of weeks, ringing gull chicks and hopefully some raptor chicks.  Over the next few months, ringed chicks will start to disperse, and it will not be long before the first re-sightings begin to trickle in.  With autumn coming, the earliest of the Continental birds will start arriving back for another winter, where the serious business of 'Ring Reading' will start once again.  Plenty to do, and plenty to look forwards to.

      Saturday 1st June 2019       
I did not have a lot of available time free for birdwatching today, but on a 'whim', I decided to make the long drive from Ballymena, to Millisle, with Common Gulls being the target species.  The trip down was well worth the effort, as I recorded two 'colour-ringed' gulls, which I last saw nearly a year ago, plus, I recorded a third 'colour-ringed' Common Gull, which was a new sighting for me.

A further four Common Gulls were present, which bore 'metal' rings, but due to the amount of disturbance by passers by, I had no hope of reading their ring numbers.  I still find it bewildering, that folk see you taking photos, but still persist in walking between me and the birds.  Did these people really get their lack of intelligence, out of a 'Lucky Bag'!!

My new sighting -   2AHX , was ringed as a chick, by Shane Wolsey, on the 23rd June 2012, on the nearby Copeland Islands.  The only previous sighting before today, was made by Jennifer Lynch, on the 13th October 2015.  Jen, recorded   2AHX , at Omeath, in County Louth, situated on the southern side of Carlingford Lough, which separates Northern Ireland, from the Republic of Ireland, a distance of around 80 kms / 49 miles (SW), from Big Copeland Island.

  2AHX , is another example, of birds from Shane Wolsey's former study, that are alive and well, and not being spotted by birdwatchers either in the north or south of Ireland.  I was well pleased with this sighting, which just so happened, solved another matter.

(Ringed as a Chick, on the 23rd June 2012, on the Copeland Islands, Co. Down)

As well as spotting a Common Gull, which was new to me, I unwittingly solved a bit of a problem in the process.  Having received all of the ringing data, from Shane's former project, the 'colour-ring' -   2AHX  , had been assigned to two different 'metal' numbers -   EX38531   &   EX38548 , but at the time of today's sighting, I did not know, that the problematic 'metal', belonged to this particular gull.

On checking my spreadsheet, I realised, that this was the very bird in question, so I began checking through all of the photos that I took of   2AXH .  Although the 'metal' ring carried a bit of dirt, the all important final three digits were clearly seen to be -   ****531 .

This now raises another problem, was   EX38548 , issued with a different 'Blue Darvic', or was it ringed with a 'metal' only.  Wouldn't it be great to solve this one as well!!  Having trawled through Shane's ringing records,   2AHX , was not the only 'colour-ring', which was assigned to two different 'metal' numbers. 

Metal Ring Showing -   ****531 

Common Gulls,   2ABF   &   2ANA , were last recorded nearly a year ago, when I spotted both birds at Millisle, on the 29th June 2018.    2ABF , is of unknown age, as it was caught and ringed as a breeding adult in 2010, whilst   2ANA , was ringed as a chick, in 2014.  Sightings of both birds are few, and have occurred during the summer months.

Unlike many of the 'colour-rings' in use, the codes for both birds are still quite legible, and it would be great to receive winter sightings.  I would hazard a guess, that both birds winter somewhere in the Republic of Ireland.

The re-sighting histories for both   2ABF   &   2ANA , can be read here (2ABF) and here (2ANA).

      From Richard Else       
Staying on the subject of Common Gulls, another one of my chicks that was ringed in 2017, has now been spotted back home, on Rathlin Island.  On the 4th June 2019, Richard Else, spotted   2APC  , at Rue Point, situated on the southern end of the island.    2APC , was ringed on the 17th June 2017, in this same spot, and Ric's sighting was a first for the gull.

Despite, Ric, stating that he was fairly sure of the code, I know he is a very competent birdwatcher, so I have excepted his sighting.    2APC , is another example, of an immature having survived two winters, without being spotted anywhere.  Out there, at the minute, are many 2018 rung chicks, which are going unrecorded.  During the summer months, many small groups of immatures, will be gathered together around the coast of Ireland, just 'begging' to be spotted by someone.

As well as   2APC   (PDF), Richard, also supplied updates for   2AJT   (PDF) and   2APT   (PDF), which also returned to Rathlin Island, this summer.  My thanks goes to Ric, for his latest sightings.

As I write this, it is almost time for me to visit Rathlin, to begin ringing this year's crop of youngsters.  On an exploratory visit a few weeks ago, I reckoned that the number of breeding Common Gulls, was lower this summer.  As most of May, and the beginning of June, has been largely wet and windy, at present, I do not have high hopes for a great number of chicks, being available to ring.


      Awful Weather       
As I've just mentioned, the weather over this past month has been quite awful, with plenty of rain and a couple of storms, having passed through Northern Ireland.  In my available free time, I had hoped to carry out some Raptor Surveying, but this has practically been a non starter due to the poor conditions.

My local pair of Peregrine Falcons are not breeding this year, as there is only a single bird on the site - a female.  On receiving an email from Jim Wells, I recently checked out another site on the County Antrim coast, where Jim had failed to locate the Peregrines there.

All was ok, as not only did I locate the female, but I also found the nest ledge, which was white with droppings.  I set up my telescope, hoping to see the chicks moving, so as I could obtain a head count.  Eventually, the inevitable happened - heavy rain began to fall.  With no sign of it abating, I ended up leaving, but will have another go soon.

The photos below, shows the nest cliff, with the nest ledge 'arrowed' on the left and the female resting on another ledge to the right.  This photo was taken partially zoomed in from the road, and the following two photos were taken fully zoomed in to the nest ledge and the female.  Hopefully, I can obtain a count on my next visit, someday next week.

Talking of Raptors, Jim has 'penned' in a return date to the islands of Islay & Jura, in Scotland.  On the trip organised on the 22nd May, we visited a Sea Eagle nest on Jura, which had at least one chick and then stopped by a Golden Eagle nest on Islay, which may, or may not have had chicks.  We will return on Wednesday 26th June, where we hope to record the exact number of chicks in both nests.  Everyone from the earlier trip, has been invited back, so this will be something to look forwards to, by all. 


      Inch Island, County Donegal       
On Tuesday morning, 4th June, I made my way to Inch Island, in County Donegal.  I had been invited, by Ken Perry, of the Causeway Coast Ringing Group, to come along to ring Black-headed Gull chicks, whilst the others concentrated on ringing the chicks of Sandwich Terns.

Ken Perry, Richard Donaghey and James McDowell, as well as myself, formed the ringing party.  Lee McDaid, and Martin Burke, Rangers from the Irish National Parks and Wildlife Service, were our hosts, supplying the boat, so we could get onto the island.

One hour was permitted for the visit, as many of the gulls and terns, were still on eggs or small chicks, therefore, we could not let these chill.  Our visit, for a change, was undertaken in calm, sunny conditions, which by the time of our departure, had begun to cloud over, with rain expected in the afternoon.

I worked away on my own, ringing Black-headed Gull chicks, being selective, and choosing only the largest, which were big enough for a 'colour-ring'.  I could have ringed loads with just 'metals', but these have a very poor return.  By the end of the hour, I had only managed to 'colour-ring', 28 chicks.  I used up the last of Adam McClure's 'Orange Darvics', that I was holding, and then began to use the 'Blue Darvics', that I had transferred from use on Common Gulls, these being from the   2F**   series.  Hopefully, we'll get a better return on these 'Blue Darvics', than we did with the previous rings used here in 2016.

Ken Perry, who has ringed Sandwich Tern chicks here for over thirty years, today, along with Richard and James, managed to ring 193 youngsters.  For the first time ever at this site, some of the Sandwich Tern chicks, were being ringed with 'colour-rings'.  However, only 8 chicks received a 'colour-ring', and no doubt, many were too small for one to be fitted.

A return visit is planned for the week beginning on Monday 17th June, where lots of the youngsters should be big enough to be either 'colour-ringed', or just 'metal-rung'.

My thanks goes to Ken, for the invite, and also to Lee & Martin, for providing an excellent service.


      Saturday 9th June 2019       
Today, saw the latest visit to the Castle Espie Wetland Centre, where I have been searching for nesting Black-headed Gulls, bearing 'Orange Darvics' from Adam McClure's project.  After Castle Espie, I visited Swan Island, at Strangford village, and then planned for a high tide visit to Millisle, in search of 'ringed' Common Gulls.  Having got to Strangford earlier than expected, I continued down the western side of Strangford Lough.

Situated near Castle Espie, I made my first ever visit to Reagh and Mahee Islands, both attached to the mainland, by a car carrying causeway.  I was curious to see what these areas would offer in terms of sighting wintering birds.  As the tide was out, the mudflats on view seemed to be very promising and will be worth a check next winter, especially on a receding tide.

With time still available before high tide, I continued down to Millquarter Bay and Ardglass Harbour.  After Ardglass, I made the long drive back around Strangford Lough, where I finished off the afternoon at Millisle.

Black-headed Gull numbers at Castle Espie, have gone from 'bad, to worse'.  Nesting numbers have decreased from last summer, and many of what I had guessed, was a large number of non breeding gulls have now gone.  After a prolonged visit, only two 'colour-ringed' gulls were spotted, plus another two Black-headed Gulls, bearing 'metals' only.

Many gulls are still sitting on eggs or small chicks, with very few larger youngsters having been recorded, which bears a resemblance to last weeks visit to Inch Island, in County Donegal.  Although, I have not re-visited the RSPB's WoW Reserve, in Belfast of late, I know the gulls there are around three weeks in advance with their breeding season.

Last summer, I recorded loads of 'colour-ringed' Black-headed Gulls, so where have they gone?  The first of the two 'colour-ringed' birds to be spotted, was my second sighting this summer of   2ASA .  Having spotted   2ASA , during my previous visit, on the 25th May, the gull did not appear to be breeding.  Today, it was in full courtship display, and a short time later, began sitting on an empty nest.  More, can be read about   2ASA , in my previous post (here).

The second 'colour-ringed' bird, was my fourth sighting this summer of   2CAN , which I can confirm, is definitely breeding.  Again, more can be read about   2CAN , in my previous post (here).

A Black-headed Gull with a 'metal-ring' turned out to be a new sighting.  It stayed perched on a fence long enough, that I took many photos of it's upside-down ring, which immediately led me to believe, that this was a Copeland bird.

On returning home, having successfully captured the number -   EX97267 , I found no entries on my spreadsheet.  I then proceeded to check Copeland Ringing Data for Black-headed Gulls, which I received a while back from Richard Donaghey.  On this, I did find a match -   EX97267 , was ringed as a chick, on the 19th June 2013.  I reported the gull through the BTO's DemOn Ringing Database, and unsurprisingly, this appears to be a first re-sighting.  It's always good to 'bag', a bird with a metal ring.

The Copeland Islands, are situated 22 kms / 13 miles (NNE), of Castle Espie, and the duration since ringing, is now 5 years, 11 months and 21 days.

The second 'metal' ring, was spotted on a Black-headed Gull, on one of the small islands, on the main breeding lake.  In fact, it was the same island, where I had recorded a 'metal-rung' bird, on the 24th March 2019.  On that occasion, I only managed to capture '  238 ', with my camera, before the gull flew off.  Today, I captured '  EY68 ', but after a lengthy wait for the gull to move position, it once again flew away.

I'm fairly certain, that both sightings belong to the same bird, but on this occasion, I cannot report it without being 100% sure of the number - perhaps better luck next time.

If this did happen to be the same gull, then the ring would read -   EY68238 .  I entered '  EY6823 ' onto my spreadsheet, deliberately omitting the final digit, to see what results I would get.

The number -   EY68238 , fell in between two 'colour-ringed' Black-headed Gulls, which I have previously recorded here at Castle Espie.  These are :-   EY68231   (  2BKP ) and   EY68245   (  2BLK ).  If -   EY68238 , is correct, then all three of these gulls were ringed as chicks, at Castle Espie, on the 19th June 2014 - Hercule Poirot, "eat your heart out".

Swan Island, Strangford
Moving on from Castle Espie, I made a brief visit to Reagh and Mahee Island, before my next stop, at the village of Strangford.  Here, I had to scope over one of the car ferries, which was moored at the pier, so that I could view the nesting gulls and terns, on Swan Island.

Despite, a very restricted view, many of the Black-headed Gulls, along with several pairs of Sandwich Terns, had quite large chicks.  Common Terns, were also sitting on their nests, obviously protecting eggs or possibly small chicks.  I was lucky enough, to spot one 'colour-ringed' Black-headed Gull, and despite the distance, I managed to capture the code -   2CND .

On returning home, and checking my spreadsheet, this was another new sighting of one of Adam McClure's Study birds.  As Adam, has not responded to emails for a year now, it was pointless trying to contact him.  I reported the gull through the BTO's DemOn Ringing Database, but apparently, the BTO, do not have the ringing details, therefore they have not been submitted yet.

Looking through my spreadsheet, I have previously recorded   2CNB ,   2CNC   and   2CNH .  These birds were ringed as chicks, on the 16th June 2017, on Blue Circle Island, on Larne Lough, County Antrim.  There's no doubt in my mind, that   2CND , were among those chicks ringed on that date.  Swan Island, lies 52 kms / 32 miles (SSE), from Blue Circle Island.  Again, I would not be surprised if this was another first re-sighting.

Ardglass Harbour
From the village of Strangford, I moved on to Millquarter Bay, where, despite a good number of the larger gulls, no rings were spotted.  On to Ardglass Harbour, I spent at least an hour and a half scoping the gulls.  With plenty of Herring and Great Black-backed Gulls present, most were lying down enjoying the sunshine.  The tide was well on the way in, so more gulls started to arrive.

Every now and again, I would throw slices of bread onto the water, to entice the gulls of the rocky islets, which are a high tide roost.  A 'colour-ring', was eventually spotted in the distance, and my camera just about caught the code -   S26:M , belonging to a Great Black-backed Gull.  I recognised the code from previous sighting of this bird.

  S26:M , was ringed as a chick, on the 8th July 2017, on Kitterland Island, which lies between the mainland of the Isle of Man, and the large Observatory island, known as the Calf of Man.  My first, and only other sighting of this gull, was made on the 29th July 2018, here at the harbour.

Today's sighting, is the fifth record of the gull on my spreadsheet.  It's first two sightings were made on the 20th June & 2nd July 2018, by unknown observers, and more recently, Graham McElwaine, recorded the bird on the 29th May 2019.  All sightings have been made at Ardglass.

With the tide now well up at Ardglass, it was time to make the now long drive around Strangford Lough, to Millisle.  On my arrival, around 25 to 30 Common Gulls were present, and immediately, I spotted a 'Blue Darvic'.  Camera out, I quickly caught the code -   2ADX , and I knew that it had been a while since I last saw this bird.  It was holding it's right leg up, so it must have been injured at some point recently.  I zoomed into the foot of   2ADX , but there are no signs of tumours, which seem to afflict a small number of gulls.

  2ADX , was ringed as a chick, on the 1st June 2010, on the nearby Copeland Islands.  My first sighting of   2ADX , was on the 24th December 2015, and I last recorded it, on the 1st September 2018.  It has a fairly good re-sighting history, and appears to be a year round resident, although it has yet to be recorded in the month of May, a month when most breeding Common Gulls, would be sitting on eggs.  The full history of   2ADX , can be read here (PDF).

Just moments after spotting   2ADX , I spotted another Common Gull with a 'Blue Darvic'.  This one turned out to be   2ACA , who I spotted recently, here at Millisle (25th May 2019).  An updated file of it's re-sighting history can be read here (PDF).

Unlike my previous visit to Millisle, where four Common Gulls were present, ringed with 'metals' only, just a single 'metal-rung' bird was present today.  I was about to photograph it's ring, when a lone Black-headed Gull appeared, which also bore a 'metal' ring.  At that time, I was using bits of bread to lure the gulls towards my car, but the BHG, was more forthcoming than the Common Gull.

Due to this, my focus switched to the BHG, which I assumed was   EW48510 , which I have recorded on two occasions, along the Millisle seafront.  Zooming in towards the ring, I became immediately suspicious, as there was a large gap between the butts of the metal, which from previous experience, the ring of   EW48510 , had no gap.

Moments later, I began to get excited, as I could see '  ET0 ' on the ring - could this be my oldest British-rung BHG.  On taking more photos, I soon realised this was indeed -   ET02500 , my old friend from Ballywalter.

In full summer plumage, this is now my seventh sighting of   ET02500 , which was ringed as a chick, on the 15th June 1998, on the nearby Copeland Islands.  I first recorded this bird, on the 16th July 2016, around Ballywalter harbour, where all of my previous sightings have been made - (December 2016, February 2017, July 2017, December 2017 & on the 13th October 2018).  Just days short, of being 21 years since being ringed, the duration now stands at - 20 years, 11 months and 25 days.

The gap between the ring butts concerns me, as it has seemed to be wider now, than when I last saw this gull.  It may only be a matter of time before the ring falls off completely, but I'm keeping my fingers crossed, as I'd love to record this gull for another year or two yet.

Having sorted out   ET02500 , my attention went back onto the 'meta-rung' Common Gull.  By now, it was raining very heavily, which by good fortune for me, kept people away.  Working on this very nervous bird, bits of bread, kept it within range of my camera, where I eventually had enough photos enabling me to piece the number together -   EX38015 , on an upside-down ring.

Returning home, and checking my spreadsheet, today's was my second sighting of this bird.  My previous encounter with this gull, was made earlier this year, on the 24th March 2019.  I wondered why this particular bird was so nervous, and on looking at the photos taken on the 24th March, told me why.  On that occasion, the gull was on the beach, and I had to take my photos from the car park, knowing it would not come near me for a free feed of bread.  Even then, like today, it pranced backwards and forwards, rarely staying still.

  EX38015 , was ringed as a chick, on the 1st June 2010, on Big Copeland Island.  The duration now stands at 9 years and 8 days, since being ringed.  This was another hard won 'metal', but I really feel great when the full number is captured.  Having entered the number onto the BTO's DemOn Ringing Database, my sightings are the only records for this particular bird.
