Well Overdue Post...

This post is well overdue, but I have not really had the time to sit down and work on it.  Everything that I've done over the last couple of months cannot be put into print, but I've presented a few snippets of what I've been up to.  This post should be the start of more frequent postings, due to the fact that some gulls are already on the move towards their wintering quarters, and the search for ringed individuals will begin again.

      Antrim Marina       
A handful of visits have been carried out at Antrim Marina to record the resident Black-headed Gulls.  Four of these were made in May - 2nd, 12th, 20th and 29th and the last two were on the 1st and 8th June.  Not a single 'ringed' gull appeared during the visit made on the 20th May.

So far, it's pretty run of the mill, with no real surprises.  Gulls recorded, except for one, have all been present during past summer visits.  It's nice to see that the juvenile -   2CJT   that was ringed here last winter, is still present, having been recorded on two occasions.    2ANS , that was ringed as a juvenile during the 2014/2015 winter, has also been sighted and now of breeding age, may well be nesting on the nearby 'Torpedo Platform'.

During my last visit on the 8th June, I recorded 12 of the 'colour-ringed Gulls, with one bird in particular grabbing my attention.    2ABN   has returned, having been classed as a non-resident.  Over the past four winters,   2ABN  departs normally in late February, except in 2015, where it stayed until late March.  It has never been sighted at the Marina in the months of May or June, with it's earliest ever return date being recorded on the 15th July, last summer.  The early return of   2ABN ,  suggests it's breeding season probably ended in disaster.

Talking of early returns, I have recently spotted Black-headed Gulls back in the estate where I live and John Clarke in Coleraine, has also commented on the return of these gulls at the harbour there.  Another instance of gulls on the move, was noted on the 9th June.  I was at a disused quarry in the hills above my home town of Ballymena, scoping for Lapwing chicks to ring, when a loose flock of around 50 Black-headed Gulls flew over, heading in a westerly direction.  It seems reasonable to assume that failed breeders are already heading towards their wintering grounds.

During my visits to the Marina, large numbers of Mute Swans have also been checked for rings.  Totals have ranged from 20'ish to 30'ish birds, all presumably non-breeders and the two usual 'metal-ringed' birds -   Z91982  and   W34158 , have been recorded on several occasions.  A third 'metal', was new to the Marina -   Z90255 .

I recorded   Z90255   on two occasions - 2nd and 12th May, but it has not been seen since.  It was ringed as a 2nd calendar year female, on the 12th February 2016, at Victoria Park in Belfast, which is situated 26 kms / 16 miles away to the south-east.

The only swans present on the 8th June, were a pair with 5 cygnets.  Both adults and their youngsters later came ashore on to the small sandy beach, but neither of the adults were ringed.

A 'metal-ringed' Drake Mallard, has also been spotted on two of my visits.  Although it is one of the Mallards released by the gun clubs in County Monaghan, I was unable to obtain the important last four digits on it's ring.

Over the course of my recent visits, the odd Common, Herring and Lesser Black-backed Gulls would arrive to steal bread from the Black-headed Gulls.  During my last visit to the Marina on the 8th June, a Common Gull, with a 'Blue-Darvic' appeared.  I knew straight away, this would be   2AJP , which probably bred in the area last year.  Scoping the ring, I soon confirmed the code and took a few photos.

You can read about   2AJP , on my new Common Gull Blog (here).

      Common Gull Project       
Now that my ringing licence has been upgraded to a 'C Permit', with endorsements to ring the chicks of gulls and raptors unsupervised, I can now proceed with my proposed Common Gull Project, 'colour-ringing' chicks at sites in County Antrim.

As Shane Wolsey, has given up on his study ringing Common Gulls on the Copeland Islands, I've taken over the use of his 'colour-rings' and study.  I have created a 2nd Blog (here), which will not only act as a platform for my project, but will incorporate sightings of gulls ringed by Shane in the past.  I will become the registered owner of the 'Blue-Darvic' series on the cr-birding (cr-birding) site in due course.

      Gulls Re-Sighted Back Home       
Every now and again, I would check the 'Live' Polish and Norwegian 'Ringing Database', to see if any of the gulls that I recorded last winter, have returned safely home.

To my delight, all four Black-headed Gulls recorded over the 2016/2017 winter, have been re-sighted back in Norway and a 5th Black-headed Gull spotted during February of 2016, has also been recorded again there.  On top of these, a 'colour-ringed' Mediterranean Gull, has been reported back in Poland for the first time since it was ringed as a chick there in May 2012.

To be continued.....
















      Belfast RSPB WoW Reserve       
I have visited the Window on Wildlife Reserve in Belfast on a few occasion, with the priority of spotting any 'colour-ringed' Black-headed Gulls from Adam' Study.  The gulls nest on two platforms on the lagoon and can be viewed fairly easily from the main building or one of the hides.

So far, I have recorded two of Adam's birds -   2ASF  and   2BHB   2ASF , was ringed as a chick in June 2013, on Blue Circle Island in Larne Lough.  Two year's passed, before it's first re-sighting's, both at Whitehouse Lagoon, which is only a short distance away from the WoW Reserve.  Suzanne Belshaw, was the first to record   2ASF , on the 4th August 2015, followed by a sighting on the 19th October 2015, by Adam.

The next sighting was made by me on the 19th March 2016, when I spotted   2ASF  here on the Reserve, presumably breeding for the first time.  After the breeding season, I recorded   2ASF  in September, October and December, back at Whitehouse Lagoon.  This is now the second breeding attempt by   2ASF  on the Reserve.

  2BHB  is another gull which was ringed as a chick on Blue Circle Island, 2nd June 2014.    2BHB , went unrecorded until the 11th September 2016, when Robin Vage spotted it on the shore at Kinnegar and later that day, I saw it at Whitehouse Lagoon.  These sites, are on opposite sides of Belfast Lough.

I re-sighted   2BHB  again on the 27th November 2016, at Whitehouse Lagoon and then on the 19th March 2017, where it was making it's first breeding attempt, here at the Reserve.  During my last visit on the 29th May 2017, I spotted   2BHB  feeding a single chick.

The Belfast WoW Reserve, is situated 22 kms / 14 miles south-west of Blue Circle Island, where both birds were ringed as chicks.

The Mediterranean Gulls, now nesting on the Reserve, are attracting a lot of interest with local birdwatchers.  These are the rarest of the breeding gulls in Northern Ireland.  Last year, two pairs nested here for the first time and both successfully fledged chicks.

This summer, there are 5 pairs nesting, all on the same platform.  While scoping these gulls, I noticed a male from one of the pairs, has a 'metal-ring'.  I had no chance reading the number, just a pity it wasn't 'colour-ringed'.

      A Visit to Rathlin Island       
On Sunday 28th May, I visited Rathlin Island on the north coast of County Antrim.  I wanted to check on the Common Gulls, nesting along the east coast of the island, as this will be my main site for 'colour-ringing' chicks, as part of my new project.  I reckon, there are between 60 to 80 pairs, with the main concentration of nests around the Rue Point Lighthouse.  This year, there are far fewer nests in Doon Bay and the presence of Great Black-backed Gulls, could well be the cause of this.

The shoreline along the east coast is extensive, with a lot of low lying rocks, where the gull nests are well spread out in a loose colony.  On the inland freshwater Lough Ushet, there are around another 20 pairs.  Most are on a small island, though three nests with eggs were found on the edge of the Lough.

A major problem with the coastal nesting Common Gulls, is the presence of a Great Black-backed Gull.  While approaching some nests near Bruce's Castle, a male Great Black-back, was observed trying to plunder the Common Gull nests.  The gulls in mass, tried their best to stave off the threat.  This was the only area, where I found several empty nests.  Overall, about two-thirds of nests contained two eggs, with three eggs in the remaining third.  Two nests were also found with recently hatched chicks - a single and one with three.

I shall be returning this weekend (17th June), to hopefully find and 'colour-ring' my first youngsters.

Moving on down the coast, I eventually fell in with the Great Black-backed Gulls nest on a small headland.  This is my first nest of this species, where I could actually get to the nest.  Nests spotted in the past, were all on rocky islands and not accessible.  This gulls nest contained three eggs and I now have 'H' sized 'metal-rings', so hopefully I will be able to ring their chicks at some stage.  Close to the nest, were the shells of Common Gull eggs, which the Black-backed's had successfully plundered.

I also fell in with four Eider Duck nests.  The first one of these, I spotted the female sitting, so I carefully approached her and took some great photos.  The other three nests, the females were accidently flushed, revealing their eggs - a 6, 5 and 3.  The nest of 6 eggs, was found on the floor of a small cave (pictured).

Oystercatchers, were numerous all along the eastern coast and numbered between 10 and 15 pairs.  I came across the chicks of two pairs and a nest containing two eggs.  Three recently hatched chicks were located fairly close together.  Another chick found along the coast, was slightly older and may have had siblings hiding nearby.  While ringing the Common Gulls, I hope to fall in with some Oystercatcher chicks, as I now have rings for these as well.

      West Side of Strangford Lough       
On Friday the 2nd of June, I undertook my first ever visit to sites along the western edge of Strangford Lough in County Down.  It was well worth the journey, as the countryside and coastline was delightful.  The main reason for going, was to check on new places to 'Ringwatch' during the forthcoming winter.


My first stop, was at the Castle Espie Wetland Centre, a site where Adam McClure has 'colour-ringed' many Black-headed Gull chicks in the past.  I was 'blown over' with what I saw here.  Not only were the gulls nesting near to people walking around, but they were unbelievably tame and approachable.  There is also a collection of duck and geese species and I hadn't a foggiest idea what half of them were.  Another visit here, is a must, on a day where I can devote more time.

While at Castle Espie, I did spot two of Adam's McClure's 'colour-ringed' Black-headed Gulls -   2BKL   and    2APB , both new to me.  I have reported my sightings to Adam and now await his reply.

At the village of Strangford, there is a small island, quite close to where the Strangford Ferry moors.  It was just a few weeks ago, that I noticed the island, while on the other side of the Lough at Portaferry.  I was there 'Ring Watching', when I noticed that the gulls were on the island and obviously nesting there.

What a remarkably small island that it is too.  Named 'Swan island', there is a sizeable colony of Black-headed Gulls and a couple of pairs of Common Gulls nesting there too.  There appears to be plenty of Common Terns nesting and a few pairs of Sandwich Terns seem to be nesting on the blind side of the island.

Spending around two hours here looking for 'colour-rings', which may well have been readable, I only spotted 'metals' - one on a Black-headed Gull and one on a Common Tern.  The highlight here was spotting a near pure-white Black-headed Gull.  This compliments to near pure black, Black-headed Gull that I spotted in Belfast last winter.

Passing through the village of Ballyhornan, I came across the roof nesting Herring Gulls, which I was made aware of in a recent email from Declan Clarke.  I counted 7 nests altogether here.

Practicularly the whole coast down the western side of Strangford Lough looks very promising for 'Ring Watching', with several sandy bays and approachable shorelines in some of the villages.

My final stop was at the village of Ardglass, which has a good sized harbour containing lots of small fishing boats and what a place it is.  There were hundreds of the larger gulls - Herring, Great Black-backed and Lesser Black-backed Gulls.  They ranged in ages from last summer's youngsters to full adults.  I did not have the time to scope all these birds for rings, but I'm sure there are a few around here.

I did however, spot three that were ringed - two Great Black-backed Gulls with 'colour-rings' and a Herring Gull which was 'metal-ringed'.  The codes and numbers were successfully read.

Both Great Black-backed's, were well known in the area, having had their codes read by other birdwatchers on numerous occasions.  The first one I got was White 1K5:C, which had been ringed as a chick on the 28th June 2014, at Horse Island Nature Reserve, in Ayrshire, Scotland.  I had three sightings recorded at Ardglass on my spreadsheet before today's record - 21st June 2015 (Declan Clarke), 17th January 2016 (James O'Neill) and on 24th August 2016 (Suzanne Belshaw).  The Nature Reserve is situated 161 kms / 100 miles to the north-east from Ardglass.

The second 'colour-ring' to be scoped was   R62:M .  Having spotted the ring, I was not able to obtain a clear photo, as the gulls were crowded together on the harbour wall and then my gull flew out to sea.  I have two previous sightings at Ardglass on my spreadsheet for this bird - 7th May 2016 (Unknown Observer) and on the 24th August 2016 (Suzanne Belshaw).

  R62:M , was ringed as a chick on the Calf of Man, on the 22nd June 2015.  The Calf, is an island off the south coast of the Isle of Man, which itself is a larger island between Northern Ireland and the British mainland.  The distance from the Calf to Ardglass Harbour is 56 kms / 34 miles in a north-west direction.

The 'metal-ringed' Herring Gull, was spotted on the rooftop of one of the warehouse's.  My camera managed to capture the number on the ring, except for the first letter -   *A39125 .  Presuming, the first letter would be a 'G', I sent an email direct to the BTO, attaching the photo below.

Lee Barber replied, to state this one was good for an old Herring Gull, but I had to report it through my ringing trainer, using the IPMR ringing sytem.  Seemingly, now that I'm a trained ringer, I have to submit all of my ring sightings this way, which is a 'pain', as I know it will take longer to receive the ringing details.  However, it will be interesting to see how old this gull really is.
