April 2014 - Great Black Backed Gulls + Gull with Yellow legs!

April 26th

Went for an hour to Bullock Harbour in South Dublin.  Quality not quantity was what I was hoping for. Strangely, I have never seen a foreign Darvic ring at Howth, despite the number of Gulls.  Well, at Bullock this afternoon, a Scottish Great Black Backed turned up.  I have seen it before, but not for 5 months.  I am looking forward to seeing if anyone else has reported it since I last saw it..
Speedy reply from Scotland.  4th sighting - all by me!

2102 Scottish Ringed + Great Black Backed Gull


There were also 2012 Great Black Backed Gull with Irelands' Eye Darvic Rings.  Including yet another that is new to me.  It is interesting to compare the plumage between the two colonies so the photos I've chosen are as close as possible to the same pose.

Interestingly, a local fisherman was asking me about a Grey Heron with a big coloured ring which was there last week. The only ones I know are ringed in Dublin Zoo, like this one I photographed this morning.  Ringed in 2007 as an Adult.

Trip to Howth this morning.  I was hoping to read the metal ring on the Gull with Yellow legs, but it didn't oblige!  Read a dozen Great Black Backed rings, all from Irelands Eye.  Again I read 2009 birds that I hadn't seen before!

April 19th

At Howth this morning trying to work out the difference between a Yellow Legged Gull and a Herring Gull with Yellow Legs! My conclusion is that we don't get Yellow legged Gulls in Ireland so it is probably a Herring Gull with Yellow legs!  P10 is visible but isn't a match to anything in Olsen's Gull Book.

April 15th

I got a mid week trip to Howth Harbour today.  Twice as many gulls as Sunday and 12 GBBGU rings from Ireland's' Eye and one Herring Gull. It is easy to read them as they sit on the roofs.




Today I photographed another 2009 Great Black backed Gull that I hadn't seen before.  They just keep turning up!

April 13th

A absolutely brilliant morning at Howth.  I arrived before 7am and 16 Brent Geese were still in the park, so I read the three with coloured rings before I even got out of the car!  But it was the Great Black Backed that made the morning so special for me.  Not only did I read 13 individuals but three were even new to me!

Great Black Backed Gull
Great Black Backed Gull 2AT was probably ringed in 2009.  This was my first sighting of this individual and it is almost 5 year old!

Great Black Backed Gull 2KL
Great Black Backed Gull 2KL was probably ringed in 2010.  This again was my first sighting of this individual and it is almost 4 year old! There is a lot of black on the Bill which makes me think it is not 2009 although birds vary.
Great Black Backed Gull 2CN
Although I have seen 2CN this year twice already.  The news is it appears to have a mate! Note the bill only has one tiny black spot, where 1AM below has a lot more black


Great Black Backed Gull 1AM
 Great Black Backed Gull 1AM seems a little behind in some of the others so possibly 2010.  It has always been a regular at Howth Harbour.
Great Black Backed Gull 1EN
Great Black Backed Gull 1EN also seems to be a little behind the adults in their striking appearance so perhaps 2010 again.  Again too much black on Bill for adult.


Great Black Backed Gull 1MC
There were a full range of Great Black Backed Gulls from 2009 to 2013.  Working out the ages takes some practice.  1MC seems to be 2012.  2nd winter - pale base develops and pale tip more pronounced.



Great Black Backed Gull 3HK
Great Black Backed Gull 3HK was ringed in 2013.  1st winter.  Note the base of the bill is dark and the pale tip is hardly noticeable.



Mystery Gull Ring
When going through my photos I noticed the following GBBGU in the corner of a frame.  I didn't see it at the time.  Either a ring has been damaged or there was a white ringed adult present!  

April 12th

Bullock Harbour this morning produced only one coloured ring in the reasonably large flock of Herring and Greater Black Backed.  Dun Laoghaire West Pier also only produced one ring.  On the way home in Tallaght there was a Iceland Gull that was in First Spring.  It was far paler than the one I see in Sean Walsh Park 1 Km away.

April 10th

I spent much of lunch time at Sean Walsh Park.  There were 70 Gulls, 4 Great Black Backed, 16 Lesser Black Backed, 39 Herring Gull, 9 Black Headed Gulls (Immature's) 1 Caspian and an Iceland Gull.  
Eventually I was rewarded with a blue Darvic - 0MA, ringed on Irelands' Eye in 2013.  It is my 6th record of this bird being recorded at this location.

April 9th

Three Herring Gulls?  The one on the right is a very different looking individual, don't thing it is anything but a variation.  Comments welcome!

April 5th

An eventful morning which started at Bullock Harbour.  Another 2009 Great Black Backed adult was present.

It is great to see lots of colour rings even though they often only show site fidelity. Nearly all the Gulls were Great Black Backed, with only 5 Herring Gulls present.  1VV was present. It is now the 7th time I have recorded it at this location.

But the most interesting observation was 1JR.  I have recorded it 10 times at Bullock Harbour but hadn't seen it since June 2013.  Nice to know it is alive and well, but where has it been?

Breeding season is fast approaching which is obvious with the various mating attempts this morning.

Dun Laoghaire Harbour near the fish Shop produced Gull of the day.  Yet another new bird for my database and a reasonable photo.


I oddest photo goes to 1LC.  I have only seen it once before, but an interesting photo.


I spent 30 minutes in Howth this afternoon.  Nearly all Herring Gulls there.  Only 1 ring read.





April 4th

First week in April has been quiet for rings in Tallaght.  The First winter Black Headed Gull from the UK is still in Sean Walsh Park!  The steady decline in Black Headed Gulls through March has taken an unexpected change.  The numbers had dwindled to 28 by the end of last month and suddenly rocketed to 140+ in early April.  They are all immature.  I am not sure if the fine weather has made the fields too hard and children feeding Ducks has concentrated the population in the park.  I've no real idea - answers on a post card.

March 30th

Howth Harbour this morning.  As the breeding season approaches I was hoping for adult Great Black Backed Gulls that have returned to breed that I haven't seen before.  Although I photographed 10 individuals of various ages- all were ones that have been seen at Howth and none were new to me.  Interesting that some of the Adults I hadn't seen since June last year.

There were more adults recorded than usual.  I hadn't seen  2AM  or 2EJ   since last summer.

March 29th

Bullock Harbour this morning but too late - the first dogs arrived at the same time as me and all the gulls were chased off the pier before I could start reading rings. I only read 1 ring and it was a Great Black Backed Gull ringed in 2013 on Ireland's Eye.  I have seen it 8 times before all at Bullock Harbour.

March 27th

A quite week for rings.  Only 29 Black Headed Gulls left in Sean Walsh Park.  The Caspian Gull has made brief appearances every day.  The Black Headed Gull 27H0 is still present, but should be leaving soon.  It is interesting to compare it to how it looked as it arrived in August.

March 23rd

Bray Harbour produced no coloured rings, so I set about reading Metal Rings on Swans and then spotted a Herring Gull with a Metal.  Eventually managed to read it with the aid of my camera.  Always harder to read them when upside down!


March 22nd

Poppintree Park had no Common Gulls today, so I went on to Howth.  Five coloured rings read, all local.

March 21st

The number of Black Headed Gulls continue to drop despite our first real wintery day with hail and sleet! The Caspian Gull and Iceland Gull 1cy are still present.   The big news of the day was an email from Maarten van Kleinwee in Holand - The Black Headed Gull E5VA has returned to its breeding ground safely again this year.  The 27th of February was my last sighting of this individual in Sean Walsh Park.

The Caspian Gull in flight.  Both wings are at different stages of moult.  Really odd looking.  Also really hard to get the colours right.  Most photos tend to under expose the bird, as the head, like in this shot, disappears against the sky! The grey in this photo is seems about right, but the black tail is far more striking in the field. 

March 20th

It has been a quite week for rings in Sean Walsh Park.  The Caspian Gull and Iceland Gull have been present most days.  The Juvenile Black Headed Gull 27H0 is still around.  The adult BLHGU have all gone but for 2 or 3 remaining.

March 15th

Howth Harbour this morning.  I was expecting more Adult Great Black Backed Gulls, but very few and only two ringed.  No Juvenile Great Black Backed Gulls with coloured rings.  The size of the Great Black Backed always impresses me.  Still 5 Herring Gulls and 2 Great Black Backed rings recorded.

I stopped in Poppintree Park and read the Common Gull from Northern Ireland again.  No sign of the Scottish Common Gull this week.

March 14th

Watching the Black Headed Gulls in Sean Walsh Park, what was striking was how suddenly there were so few adults - about 5%.  Usually St Patricks' week-end is the last weekend of reading adults so maybe they have all departed this week.  The Juvenile 27H0 is still around.  Best of the day was the Herring Gull 0MA.  Since I first spotted it in the Park in December, this is the 5th re-sighting.  The Caspian Gull and Iceland Gull were around again today at lunch time.

Black Headed Gull 27H0 - should be around for one more week.

March 13th

The Black Headed Juvenile 27H0 is the only Darvic seen in the Park this week.  Today the Iceland Gull gave me great views and the Caspian Gull even gave an appearance.

On March 8th I mentioned that when reading wader rings, I met a wildlife photographer, John Fox. Together we were observing the Redshank and reading the rings.  He has kindly given me permission to use one of his photo's of the Redshank we were watching.  Reporting of such rings can be done through the Dublin Bay Blog and they are prompt at getting back to you.

March 9th

Bray Harbour this morning, to see if the reported Black Swan has any identifying ring on it - it doesn't.  The usual Black Headed Gulls, sporting Darvic rings, were not about.  They may have already left for their breeding grounds or just elsewhere.  My highlight was another Great Black Backed Gull from Irelands Eye. 3CT was ringed during the Summer of 2013, but this is the first time I've seen this individual.

Before I left Bray I photographed a metal ring on a Black Headed Gull from Finland.  I got the full code so I will report it tonight.  This is the 3rd Helsinki metal ring I've read this season!

I stopped at Bullock Harbour on the way home and read three more Gulls from Irelands Eye, (2 GBBGU and 1 HERGU).  Three Mediterranean Gulls still present including this German individual.

March 8th

Sean Walsh Park and the roost at Tallaght Community Schools, both failed to turn up ringed individuals.  At Poppintree Park the Northern Irish Common Gull with the Blue Darvic was present.  It was ringed on Big Copeland in June 2013.  No sign of the yellow ring from Scotland.  Then off to the Bull Island.  The redshank with rings were visible but thankfully John Fox turned up with a scope so that they could be read.

Red Shank at the Bull.  Spot the rings?

March 5th

Still the gathering of Gulls for migration hasn't really been noticeable and it certainly hasn't produced some of the regulars who turn up in March.

March 4th

No rings read today apart from Black Headed Gull 27H0 which is daily.  A very sociable lunch time with many birders around and the Caspian Gull obliged with brief showings.  The Iceland Gulls were less obliging today!

March 3rd

The first Black Headed Gull in breeding plumage is from Sweden and I didn't get its number.  It started with 6430, so I think I know which bird it is.  It will be interesting to see if all the Scandinavian birds change first.

March 1st

The afternoon trip was to Poppintree Park in North Dublin, to check and see if the Common Gull from Scotland was still present.  A circling Buzzard had all the Gulls up.  But the first Common Gull ring I saw was Blue! I have sent a report to Northern Ireland. It was ringed on Big Copeland, thanks to Shane for his swift response.

I returned to the Park an hour later and observed the Scottish Common Gull with the Yellow Darvic ring.  Not much of a photo but 5/5 for attendance.

The morning had started with a quick trip to Sean Walsh Park.  There were more birders than Gulls this morning, but the Caspian Gull had been around earlier in the morning and all eyes were on an Iceland Gull on the Plaza Hotel.

Waiting for the Caspian Gull to return!
