Norwegian LBB Gull...

      Antrim Marina - Monday 24th July 2017       
Today, I stopped by Antrim Marina for a couple of hours, to watch out for any of Adam McClure's 'colour-ringed' Black-headed Gulls.  The weather, being very warm and sunny, probably had an effect on the number of gulls present at the Marina, as very few birds appeared.

Larger gulls, were more evident than the BHG's, which is the reverse to normal sightings here.  Lesser Black-backed Gulls, put in a very good showing, along with a few Herring and a couple of Common Gulls.  A couple of fledged chicks were also present, these being BHG and LBB Gull, youngsters.
Only two of Adam's Study birds appeared, these being   2AAF  and   2AAT , both known to be residents in the Antrim Marina area.  The pair of Mute Swans, along with their five cygnets, are very popular with folk coming to feed the ducks.  Some people have asked me, did I know where the other swans went too?  A couple of months ago, numbers ranged between 20 and 30 birds, which does pose a good question, where do the go?

Black-headed Gulls Re-sighted at Antrim Marina  (24 Jul 2017)

Sitting in my car waiting for gulls to appear, I had a 'hell of a surprise', when an immature Lesser Black-backed Gull, landed about 15 feet away from me.  Having spotted a 'Black colour-ring', I grabbed my camera and started taking photos.  I could read the code, which was   J638Z   and proceeded to try and catch the number on it's 'metal-ring'.

The gull flew off, remaining in the area for about 10 minutes and then departed.  Checking my photos for the 'metal-number', all I had was Norway   4280*** .  It was just as well, that this gull bore a 'colour-ring', as I would not have been able to confirm the 'metal'.

Once I returned home, I entered the 'colour-ring code' onto the live Norwegian Ringing Database and soon had the gulls details.  It was ringed as a 1st Calendar Year Male, on the 30th September 2016, on Lake Langvannet, just to the east of the Norwegian Capital - Oslo.

There had been one previous re-sighting of   J368Z , before I spotted it at Antrim Marina.  On the 18th April 2017, it was re-sighted in Sidi R'bat, in southern Morocco.  Did it go there for it's summer holidays?  Sidi R'bat, is 3,659 kms / 2,273 miles, south-south-west from Lake Langvannet, whilst Antrim Marina is 1,181 kms / 733 miles from the lake.  The ringer, Morten Helberg, will be well pleased with these sightings.

      Ringing Details Received       
I have receieved the ringing details for the Herring Gull that I spotted on the 2nd June 2017 (Read), at Ardglass Harbour, in County Down.  Although, I was missing the first letter on the metal ring, while taking photos, I knew it would start with the letter 'G', as it was a BTO ring.  I emailed the photos to the BTO and they confirmed that the gull looked good for an oldish bird.

  GA39125 , was ringed as a chick, on the 28th June 2002, on the Calf of Man, which is a small island, just off the south coast of the Isle of Man, which itself is situated in the Irish Sea, between Northern Ireland and England.  The duration from ringing till my sighting is 14 years, 11 months and 5 days, therefore making   GA39125  the oldest Herring Gull on my records.  Ardglass, lies 56 kms / 34 miles, WNW from the Calf of Man.


      Further Re-sightings of Polish Ringed Gulls       
The Mediterranean Gull   PNU0 , has been re-sighted twice, since my last update on it's return to Poland.  Ringed as a chick in May 2012, there had been no reports of it returning to Poland, until the 14th May 2017, when it was spotted on Lake Mietkowski (Blog Post).

  PNU0 , was seen in Swidnica area on the 24th and 25th June, having now moved 12 kms / 5 miles, SW from Lake Mietkowski.  Could this be the start of it's journey back to Northern Ireland?

The Black-headed Gull -   T58T , which was recorded at Lurgan Park last winter, has now been recorded back in Poland.  On the 15th July,   T58T  was spotted at Świnoujście, where it was ringed as an adult, just one day short of a year ago, on the 16th July 2016.  Świnoujście, lies on the north coast of Poland, close to it's border with Germany.

Common Gull Bonanza...

      Waterfoot, Torr Head & Ballintoy - Saturday 8th July 2017       
Today, I went looking for Common Gull chicks at two sites, where they are known to breed and then went looking for a colour-ringed adult.  This one was reported to me via an email from Richard Donaghey, who spotted it at Ballintoy, on the north coast of County Antrim.

Around three weeks ago, I checked out the Common Gull site which is located just outside of Waterfoot, on the road to Cushendall.  I discovered the gulls nesting here last summer and 2 chicks were 'metal-ringed'.  On my previous visit, I reckoned that there were 5 pairs this year, with at least one of these definitely nesting.

Today, I spotted a fully feathered youngster on the rocks, where I had found a nest the last time out.  I had missed the chick, while searching for young.  Moving up the shore, I then spotted two ring-able youngsters on a seaweed covered rock, slightly off-shore.  As the tide was out, I thought it might be possible to catch these on a high tide and planned a return visit a couple of days later.

Moving on to Torr Head, on the east coast of County Antrim, there is a small island that can be reached, with a tricky decent of the mainland cliff.  Around 20 pairs of Common Gulls are known to nest here.

After arriving, I took my telescope with me to have a look at the island, which would give me an idea of how many chicks were running about.  To my horror, something has happened here, as there was only a single adult Common Gull and a single adult Herring Gull.  Although the island was covered in droppings, there wasn't a single chick to be seen.

Something has gone terribly wrong here and the gulls have obviously deserted the island.  Even if full grown youngsters had fledged, they would have still been present along with their parents.  This was a major blow to me, as I was hoping to 'colour-ring' at least 20 chicks here.  The whole island was covered with droppings, which suggested there had been lots of gulls here in the recent past.

Finishing the day at Ballintoy, there were Common Gulls here and several pairs had nested.  I found empty nests on rocks attached to the mainland, but here again, not a single chick was found.  Chicks were spotted on small rocky islets, which would be permanently surrounded by the sea.  I've no idea, whether these gulls have been known to nest here in the past, but the shoreline in the area needs to be checked out and properly accessed.

Scoping, what gulls were present, I could not find the bird that was 'colour-ringed'.  Perhaps another visit on a quieter day might help, as there were a lot of people visiting the area.  I returned home, disappointed that no gull chicks had been ringed.  


      Waterfoot, Carnlough & Glenarm       
I returned to Waterfoot on the 10th July, making sure my visit coincided with a high tide.  I successfully captured and 'colour-ringed' the two chicks, spotted here two days ago.  I also spotted another youngster which was fully feathered and capable of flying.  I re-checked the spot, where I'd seen the other large chick two days ago and it was still there.  This meant that three of the five pairs, had raised 4 young between them.

With Waterfoot sorted, I decided to check the gulls at Carnlough Bay for rings and spotted more than I was expecting.  Several birds were seen with 'metal-rings'.  A Great Black-backed Gull and a Common Gull, are probably the same birds that have been seen in the past.  It is impossible to get close enough to read their rings, as the gulls here, don't allow close approach.

Six Sandwich Terns were also present and three of them were 'metal-ringed'.  Although, many of the gulls were lying down enjoying the hot sunshine, my patience was rewarded when some of the gulls started to move about.  Two 'colour-ringed' Common Gulls were then spotted.    2HTX , is well known to Carnlough Bay, but as yet, has never been spotted elsewhere.  This gull was ringed as a chick on the Copeland Islands on the 2nd June 2011.

The second 'colour-ringed' Common Gull was a bird that I instantly recognised -   2H22 .  This was the same bird that I spotted on the 16th December 2016, at Sandy Bay in Larne.  Ringed as a chick on the 26th June 2016, on the Isle of Arran in Scotland, it was first recorded in Northern Ireland on the 14th September 2016, when Cameron Moore spotted it at Whitehead.

Realising, I had forgotten to bring my camera with me, I returned the next day, but all I could get on the ring was   2H , before a man out walking his dog, scared all the gulls away.  Not to be deterred, I returned for a third day (12th July) and this time managed to get a photo.  It is now 1 year and 16 days, since   2H22  was ringed.

I then drove the short distance to Glenarm Harbour, where I re-sighted a Black Guillemot around three weeks ago, with a yellow 'colour-ring', which I presumed was   FT .  Although the bird was on the water, it was too 'choppy', for the camera to capture a picture of the code on the ring.

Today, the water was 'flat-calm' and after two attempts, I managed to get a picture of the ring and it's code.  My Guillemot, was indeed   FT , nesting in the very same hole in the harbour wall, as it did in the last two years.  My first sighting of this bird, was made on the 26th June 2015 and I got it again last summer on the 13th July.

  FT  was ringed as a chick on the 3rd July 2005, with today's sighting coming 12 years and 9 days later.  Julian Greenwood, who sadly passed away in April this year, had a long running study of the Black Guillemots at Bangor in County Down, where   FT  had been ringed.  The only previous sighting of   FT , was also made at Glenarm Harbour, on the 17th July 2011.

A second Black Guillemot, was spotted below the north wall of the harbour and had a 'metal-ring'.  Two years ago, a 'metal-ringed' bird nested close to   FT's   nest hole on the west side of the harbour.  It's frustrating, that these 'metals' cannot be read, as the birds here are well used to people, but there is no chance getting codes when the birds are on the water

      County Down - Friday 14th July 2017       
With a trip to Rathlin Island planned for tomorrow, I was going to ask for, 'tounge in cheek', for a half day holiday, but tried my luck at a one day holiday.  With so many fellow workers in my department on their holidays, I was surprised to have my request, granted.  I work an evening shift, Monday to Friday, starting at 6pm and finishing at 2am.  With an early start on Saturday morning, getting the whole day off, gave me options for Friday day.

With the breeding season coming to an end, I decided to go 'Ring Watching' in County Down.  What I was not expecting, was a Common Gull Bonanza, with many ringed birds being encountered.

Arriving at Groomsport Harbour, I was in business straight away, as a 'metal-ringed' Common Gull, was spotted on the roof of the Harbour Master's Office.  With only a couple of photo's taken, the gull flew off, but never returned.  Checking the photos, I only captured a partial number -   EJ****7 .

I would be fairly certain, that this was   EJ72587 , whose whole ring number was confirmed, during a visit to Groomsport Harbour on the 4th September 2016 (Read).    EJ72587 , is the third oldest Common Gull on my records, having been ringed as a chick in July 2003, on the nearby Copeland Islands.  Confirmation of today's gull would be great, as it is now approaching 14 years of age.

Waiting for the return of   EJ****7 , a Common Gull with a 'metal-ring', eventually landed on the Harbour Master's Office, but actually turned out to be a different bird.  Frequently taking off and returning, I managed to obtain enough photos to complete the number on it's 'upside-down' ring.

This one was   EW51618 , which was a new sighting for me.  As I now have all of Shane Wolsey's records, from his Common Gull Study, I was able to check out the gull's details.    EW51618 , was ringed as a chick, on the 6th June 2009, on the Copeland Islands.  The duration since being ringed, is now 8 years, 1 month and 8 days.

Moving on round the coast to Donaghadee, I parked in the spacious car park, close to Donaghadee Community Centre.  Although, there were few gulls about, throwing bits of bread out of the window of the car, soon attracted quite a number of birds, with three 'ringed' gulls appearing at the same time.

A Common Gull, bearing a blue 'colour-ring', was quickly sorted and the code read -   2ACJ .  Checking my records after returning home, this was the same gull that I spotted on Kinnegar Beach, just outside of Belfast, on the 22nd December 2016.  That particular sighting was a first since the gull had been ringed as a chick, on the 14th May 2010.  Again, ringed on the Copelands, my sighting today makes it 7 years and 2 months, since   2ACJ   was rung.

The other two gulls, bore 'metal' rings, the easiest of these to work on, was a Black-headed Gull, the other being a Common Gull, which was quite wary.  With a lot of patience, I managed to capture the numbers on both rings.

Black-headed Gull -   EX97264 , is a bird that I've recorded on three previous occasions along the Donaghadee seafront.  Ringed as a chick, on the 19th June 2013, it's now 4 year's and 25 days, since being rung on Mew Island, which is part of the Copeland Islands.

Although the 'metal-ringed' Common Gull, was at first quite wary, it soon settled and moved in for a share of the bread.  Checking my photos before departing, I successfully captured it's ring number and it turned out to be the second new sighting of the afternoon.

Ringed   EW51627 , this gull's number, is only 9 digit's of difference, from that of my first new sighting a short time earlier, at Groomsport.  It was also ringed as a chick on the same date (6th June 2009) and location (Copeland Is.), as   EW51618 .  The duration since ringing, being 8 years, 1 month and 8 days.

Arriving at the seafront here in Millisle, this is an area that is considered as a 'hot spot' for 'ringed' Common Gulls and today's visit could be classed as 'red hot'.  Amongst an estimated 60 to 70 Common Gulls, 6 'colour-ringed' and around 15 'metal-ringed' birds were present.

The codes on the 'colour-rings' were easily obtained, which included two first-ever sightings for me.  The 'metals' were a nightmare, as the gulls kept moving about and I therefore decided to concentrate on just one bird, this being an immature, which would have hatched during the summer of 2016.

This young gull, turned out to be the sighting of the day, as it bore a Norwegian ring and I successfully captured the number, making it the third 'metal' of the day to be read.  Ringed -   5182366 , I am still waiting on it's details.

The first of the two new 'colour-ring' sightings for me, was that of   2ACV .  Ringed as a chick, on the 28th May 2010, on the Copeland Islands, this is a very early date to find young capable of taking a 'colour-ring'.

The only previous sightings of   2ACV , were both made by Graham Prole. The first was way back, on the 15th September 2013, on the Malahide Estuary, just north of Dublin.  The second, more recent sighting, was on the 11th February 2016, when    2ACV , was spotted at Broadmeadows, Swords, which is not far away from Malahide.

With today's sighting, it is now 7 years, 1 month and 16 days, since   2ACV   was ringed.  It appears, that this gull could be returning to breed on the Copelands and then 'winters' in the Malahide area.

The second of the two new 'colour-ring' sightings for me today, was that of   2ALN .  Corressponding with Shane Wolsey, it turns out, that this is the first sighting since it was ringed as a chick, on the 18th June 2012, also on the Copeland Islands.  It is now 5 years and 26 days, since   2ALN   was ringed.

One other 'metal-ringed' Common Gull, landed briefly on the beach in front of me and there was no mistaking who this one was.  This is the gull that I named 'Stumps'.  Grabbing the camera and taking a couple of shots of the ring, I still cannot get the whole number.  I first recorded this 'footless' gull on the 13th August 2016, when I got a partial number -   E**820* .

My second sighting of 'Stumps', was made on the 4th February 2017.  Despite it's handicap, it appears that the gull is surviving quite well.  I have recorded a second 'footless' Common Gull here in the past, but that one does not have a ring.

The final four 'colour-ringed' Common Gulls, are reguarly seen around the beach and car park area of Millisle.  The oldest of these, is   2BBC , ringed 8 years and 21 days ago.    2ACA   and   2ABF , were ringed as breeding adults, the duration of these now being, 7 years and 2 months.    2ADX , was ringed as a chick, 7 years, 1 month and 13 days previous.  All four were ringed on Big Copeland Island.

Two 'ringed' Herring Gulls, were also re-sighted at Millisle Beach.  'Metal-ringed' -   GA00153 , was ringed on the Copelands, 12 years and 22 days ago, on the 22nd June 2005.  It was the oldest Herring Gull on my records, but this has been bettered by a bird that I spotted at Ardglass Harbour on the 2nd June 2017.

I'll post the details on that one, once I receive the ringing details for the Norwegian-rung Common Gull (above).

  4M:W , comes from a recently started project on the nearby Copeland Islands.  Ringed as a breeding adult, on the 6th May 2015, today's sighting, is my fourth record of this gull at Millisle.  The duration of this one is now, 2 years, 2 months and 8 days.

      Rathlin Island - Final Visit - Saturday 15th July 2017       
As mentioned in my previous post, many Common Gull nests were located which had eggs, these largely being replacement clutches, presumably by pairs that had lost eggs or chicks to a pair of Great Black-backed Gulls.  I was hoping to 'colour-ring' at least a dozen chicks, to bring the total on Rathlin to 50.

During today's visit, despite extensive searches at each site, not a single chick was found.  The only youngsters to be seen, were earlier bred chicks that were now strong on the wing.

While on Rathlin three weeks ago, I suspected that a second pair of Great Black-backed Gulls were present at the north end of Arkill Bay.  Although a single adult was alarm calling and a possible nest discovered, I could not go looking for the chicks, as I did not want to frighten Common Gull youngsters, should they jump prematurely onto the sea.

Arkill Bay, was where I found most replacement Common Gull nests, but the only two chicks discovered here today, belonged to the Great Black-backed Gulls, with both adults present this time.  Unfortunately, the chicks were too large and wary to attempt to catch.

It would appear, that the two pairs of Great Black-backed's, have caused a lot of damage preying on the Common Gulls.  I reckon that those Common Gull chicks that did fledge, all came from the peak hatching time and survived the carnage caused by the larger gulls.

Although this was my first summer at 'colour-ringing, I've learnt a lot about the gulls here and what goes on.  Next year, I know to make a concentrated effort for perhaps two or three days, around the 20th June.  This should ensure, that I can get a maximum numbers of chicks 'colour-ringed'.

Having covered the coast, I checked out the inland Ushet Lough, while returning towards the harbour for the return ferry.  Here again, the replacement Common Gull nests had all failed, with no chicks being spotted.  Even on the tiny island, where several of pairs were on nests three weeks ago, not a single chick could be seen.

Checking the Greylag Geese on the Lough for 'Collars', the only one spotted was   NDD , present on my previous visit.

Leaving Ushet Lough, I walked over to the cliffs on the west side of Rue Point.  Here, I discovered another small Common Gull colony on the rocks below, with around a dozen fledged youngsters.  I made my way down to check out the site and located at least 8 old nests.  I'll visit this one next year.

All in all, I only managed to 'colour-ring' 36 Common Gull chicks, out of 50 that I was hoping for.  Four more chicks were just 'metal-ringed', as they were too young to take a 'colour-ring'.  With just two chicks 'colour-ringed' on the east coast of County Antrim, my overall total fell short of what I was hoping for.


      Antrim Marina - Sunday 16th July 2017       
Visiting Antrim Marina, late in the afternoon, very few Black-headed Gulls were present and it seemed that most were 'breaded-out', having been fed all day long.  Only two of Adam's Study birds were spotted, firstly   2AAF  and then   2ABA   2ABA  is interesting, as we know this gull is a non-resident.  This gull usually departs in late February or early March, but it's breeding site is as yet unknown.

The return of   2ABA , proves that BHG's are on the move towards their wintering sites.  A surprising feature here, was the lack of fledged chicks, with just three counted.  It would be an indication, that the gulls have had another poor breeding season out on the 'Torpedo Platform.

Four Common, four Lesser Black-backed and two Herrings Gulls, were also present throughout my short visit.  Amongst these, I spotted Common Gull   2AJP   again.

Rathlin, Ailsa & Antrim...

      Rathlin Island       
On the 17th June, I along with three others, began the process of finding and 'colour-ringing' Common Gull chicks, the start of my new venture.  With one person pulling out at the last minute, I was accompanied by my sister Heather, family friend Michael Wright and fellow 'Ring Watcher', Suzanne Belshaw, who had to travel up from Lisburn.  My thanks, to all for their help, especially Michael, who was like a 'Whippet', running around looking for chicks while I was ringing.

We spent all of our time in the Rue Point area, which is the main site for nesting Common Gulls on Rathlin.  Two sessions of searching, was divided by a 'lunch break', in order to give the gulls a bit of peace for a while.  I was planning a second visit to the island the next day, but this was changed, as a trip to Ailsa Craig in Scotland was finally given the go ahead.

Only 22 chicks were found and 'colour-ringed', with a further three smaller chicks just receiving 'metals'.  In contrast to the number of nests with eggs found here three weeks ago, the number of chicks located was very disappointing.

An Oystercatcher chick was also found a ringed and while my sister and Michael made their way back to the harbour, Suzanne and I made our way to the Great Black-backed Gull nest at Doon Bay.  This nest contained three eggs, three weeks ago.  You could imagine my horror, as Suzanne and I rounded the corner into Doon Bay, a largish group of people could be seen on the headland where the GBB Gulls were nesting.

Arriving onto the headland, the nest was empty, but there was plenty of signs that there were chicks about.  Asking one of the party of people, had they seen any chicks, a man stated he had seen one and showed us where it was.  Suzanne, then found a second chick and both were 'metal-ringed', much to the delight of the onlookers, who found the experience very interesting.

On Twitter
Between my two visits to Rathlin, Adam McClure, sent me an email headed, 'You've Been Busy'.  He spotted a photo on Twitter, taken on Wednesday 21st June, with three of the Common Gull chicks that we ringed on the 17th, at Rue Point.  I checked this out and sent a message asking if I could use the photo on my Blog.

I have not received a reply, but the photo was probably taken by Ric Else or Hazel Watson, whom I believe are working with the RSPB on the island this summer.  I've added the photo anyway and hope the photographer does not mind.

Second Visit to Rathlin Island  -  24th June
A week after my first session of ringing, I returned to Rathlin, looking for some more Common Gull chicks to 'colour-ring'.  This time I was on my own, as other members of the party pulled out at the last minute.

I decided to stay on the island all day, returning on the ferry the next morning.  I also took the telescope with me this time, aiming to check as many adult Common Gulls as possible, for 'metal' or 'colour-rings'.  After scoping, perhaps a couple of hundred breeding and non-breeders, not a single ring of any sort was spotted.

I did have success at my first site visited, that being on the slightly inland - Lough Ushet.  Here, I spotted a Greylag Goose, with an Orange 'neck-collar', reading   NDD .  This was the same bird, that I spotted here last summer on the 3rd July.  Reporting my sighting to Clive Mellon, he replied to say that   NDD , had been spotted on four occasions in February 2017, on Lough Doo, at Fair Head.  Fair Head, lies just to the east of the town of Ballycastle on the mainland and is separated from Rathlin by a short stretch of the sea.

  NDD , was originally ringed, as a juvenile female, on the 11th November 2014, near Bowmore, on the Scottish island of Islay.  Bowmore, lies 54 kms / 34 miles to the north of Rathlin.

Walking around the shore of Ushet Lough, I found two Common Gull chicks, that were duly 'colour-ringed'.  The small island at the western end of the Lough, had several pairs of Common Gulls.  There was a vast difference in the breeding cycle, as up to 15 large chicks were excercising their wings for first flight, while several pairs were still sitting on eggs.  Two other nests containing eggs, were found on the shore of the Lough.

On to Rue Point, where the main Common Gull colony is situated and the stage of last Saturdays visit,  only a further two chicks were 'colour-ringed' and a smaller chick, was just metal-ringed.  An hour search for other chicks, provided only sightings of birds rung on the 17th.  A surprise feature here at Rue, was the absence of nests containing eggs.

At Lough Ushet and other sites visited during the course of the day, many nests were found containing eggs.  These were probably repeat clutches, laid by birds that had lost their original eggs or chicks.  Amongst these, there could also be some late nesters still on their first clutch.

The Common Gull colony at Doon Bay, had been practically wiped out.  Not a single chick was found, but three nests were located with eggs.  I reckon the pair of Great Black-backed Gulls at the north end of the Bay, have had plenty of feeding on the Common Gull eggs and chicks.

Last Saturday, Suzanne and I, made are way up to check on the Great Black-backed's nest, before returning to the harbour to catch the return ferry.  We located and 'metal-ringed' two chicks, but during the week, thinking about these, I realised that we never took time to search for a third, as the pair were sitting on three eggs on the 28th May.

Returning to the headland, I soon found the first 'metal-ringed' youngster, quickly followed by one with no ring, which soon had one fitted to it's leg.  A few minutes after, I found the other 'ringed' chick.  All three had been hiding on the precipitous cliff on the edge of the headland.  I had to lift them all and place them on the flat top, in order to get a photo and ensure their safety in case they fell onto the sea.

Great Black-backed Gull Chicks  -  Doon Bay, Rathlin Island  (24 Jun 2017)

Between Doon Bay, moving northwards towards Bruce's Castle, are three smaller colonies of Common Gulls and some isolated pairs.  At Arkill Bay and Portnaminnan, a further 10 young Common Gulls were 'colour-ringed', bringing the overall total for the two visits to 36 'colour-ringed' and 4 with just 'metals'.  I was raging with myself, as a good 20 to 25 youngsters here, were so big that they could easily have taken flight, or flapped out on to the sea.

Having decided to take the opportunity of a trip to Ailsa Craig, instead of returning to Rathlin for a second day last weekend, has cost me many ring-able youngsters.  A number of nests here also had eggs.

The last colony by Bruce's Castle, had been wiped out.  It was here, that I observed a Great Black-backed Gull, trying to raid nests on the 28th May.  Very few pairs of Common Gulls remained and another couple of nests with eggs were found.

It appears, that the Common Gulls have experienced an unsettled breeding season, probably not helped by the weather over recent weeks, which has seen much rain and strong winds.  I'll try and return for one further visit in mid-July and hopefully, will complete my target of 50 colour-ringed chicks.

Two Swallow's nests were found in a derelict cottage.  The first had 5 chicks capable of flying, but the second nest had 5 smaller chicks, that were ringed.


      Ailsa Craig       
I had planned to pay a second visit to Rathlin Island, but the chance of a trip to the island of Ailsa, could not be dismissed.  Several planned visits in past weeks, were cancelled due to weather conditions.  I had wanted to access the size of the Lesser Black-backed Gull colony, situated beside the Lighthouse Keeper's Cottages, with the view of perhaps 'colour-ringing' chicks here in the future.  I also wanted to check the adult gulls for rings, while on the island and to try and locate a Peregrine Falcon nest.

After landing on the island, the boatman was only allowing us about an hour, before returning.  I was disappointed by his decision, as it did not allow me time for what I had planned.  Briefly checking the gulls on my way to the Peregrine site, no ringed birds were spotted.  The colony itself, had a few pairs of Herring Gulls nesting amongst the Lesser Black-backed's.  This would present a problem when ringing, as their chicks look similar at an early age.

At the Peregrine site, it did not take long to spot a fully feathered youngster on the towering cliff face.  Taking a while to scope the cliff for other youngsters and a nest-ledge, I was quite satisfied, that my youngster was a single and was actually standing on the nest.  A used Raven nest was also found close by, but I'm fairly sure the Peregrines did not nest on this.

While I was away, my sister Heather, who came with me on the trip, managed to scramble up a boulder slope, where she found a Shag's nests containing three smallish chicks.

      Latest At Antrim Marina       
On Sunday 25th June, I made a late decision to check out the rooftop nesting gulls at the Tesco Warehouse in Antrim and also pay a visit to Antrim Marina.

It was hard to view all of the rooftop at the warehouse, as the leaf cover in the trees are obscuring most of the nesting gulls.  From what I could see, there are now plenty of young Lesser Black-backed Gulls running about.  A few Common Gull chicks were also spotted, but I'm not sure if any belonged to the Mediterranean x Common Gull pair.  Although a few adult Common Gulls were present, there was no sign of the Med Gull.

At Antrim Marina, I recorded 8 of Adam's 'colour-ringed' Black-headed Gulls, all being 'residents' to the site.  The first two fledged chicks were also present amongst the 60 to 70 BHGs.  Now that we are entering the month of July, I shall begin starting to search for rings, as many gulls will have completed their breeding season and will be making a move towards their wintering sites.

Black-headed Gulls at Antrim Marina  (25 Jun 2017)

The Common Gull -   2AJP , spotted on my last visit to the Marina, was also present.  The only Mute Swans, were the same pair with 5 cygnets, which were also recorded on my previous visit.
