Another new GBBG from Cornwall, England

The lower tide and calmer weather this morning resulted in near perfect conditions for viewing the gull flock at L’Eree Beach just after dawn. Amongst the 350 Lesser Black-backed Gulls were 19 of my birds colour-ringed in the Bailiwick of Guernsey, together with the relatively long-staying juvenile bird (White C+G) from Bath, England. The LBBGs included a 2009 chick – Black 0.F6 (from Burhou, Alderney) and a 2010 chick (Black 4.F1) from Sark. Eleven cr Great Black-backed Gulls were present in the flock of 150 birds – these included yet another new bird from Cornwall (the fourth in as many days), the Norwegian bird (Black JX14) first seen yesterday, and three French birds (all previously seen on Guernsey – Black 34H and Blue 47D from Le Havre, Seine-Maritime and Green E.41 from Chausey Islands).

...and Another Great Black-backed Gull from Norway

The weather was worse today with frequent rain showers and gale force winds around dawn. L'Eree Beach was the place to be with a flock of c100 Great Black-backed Gulls and 300+ Lesser Black-backed Gulls. Amongst the GBBGs were Black JX14 (ringed as a chick in Vest-Agder in June 2007 - Morten Helberg) and Green E.44 (ringed as a chick in July 2009 on Chausey Islands, Manche, France - Seb Provost).

The only foreign cr LBBG was White C+G, a juvenile ringed by Peter Rock in Bath, England , and which has been seen in Guernsey on 08 an 12 August 2011.

Norwegian GBBG Back in Guernsey!

It was another superb early morning at L'Eree Beach today, although with wind and rain showers conditions for watching were less pleasant. This morning's highlight was the sighting of Great Black-backed Gull Black JH254 - a 2nd winter bird, which was ringed in Vest-Agder, Norway in July 2010, and seen in Guernsey a year ago almost to the day - so this is another gull showing site fidelity on its migration! Amongst the flock of 100 GBBGs on L'Eree Beach were four French-ringed birds (all from Le Havre, Seine-Maritime - Blue 47D, Blue 30C, Black 17E and Black 34H) and another from Cornwall, England (White L:AS2).

Amongst the 100 Lesser Black-backed Gulls were Blue YH05 from Iceland, and eight locally colour-ringed birds. There was an even larger flock of GBBGs and LBBGs on L'Eree Aerodrome, but the long grass prevented any rings being read at this site.

Icelandic LBBG Back in Guernsey!

After two very disappointing post dawn trips down Guernsey’s west coast, when I failed to find more than a few Lesser or Great Black-backed Gulls, I got lucky today! The tide was better this morning, and on both L’Eree and Perelle there were decent flocks of LBBGs – in total around 200 birds. One of the first colour ringed birds seen was Blue YH05 – an Icelandic breeding bird, which used Guernsey’s west coast as a migration stop-over at this time of year in 2010. It is amazing how some of these gulls really are creatures of habit – even using the same migration stop-over locations! Not to be outshone by this exciting visitor…my own cr LBBGs soon began to appear…and I ended my session with 14 Guernsey and Alderney LBBGs recorded! The last cr LBBG seen, shortly before the flock on Perelle was flushed by a passing motorcycle, was a 1st winter bird – Red S:097 – a bird from a new project in SW England run by Mike Bailey.

As if this wasn’t enough excitement I also found two Great Black-backed Gulls from Bruce Taggart’s project running at St George’s Island, Looe, Cornwall, England – L:AJ8 (recorded in Guernsey on 31 October 2010 and 15 January 2011) and L:AS0 (a 1st winter bird recorded here for the first time).

Tim Earl also recorded a LBBG (Black SJ) at L’Eree on 15 September, which had been ringed in Bristol in 1994 by Peter Rock.

And finally…the Polish colour ringed Black-headed Gull, which spent last autumn (and this autumn so far) in Guernsey - White TARM - was on L’Ancresse Common last evening – all in all a really outstanding 24 hours for recording cr gulls in Guernsey!



On Holiday in Portugal

We have just returned from a  week's family holiday based at Azoia, near Sesimbra, Portugal. Each morning I was able to search the gull flocks at Sesimbra Beach and Fish Port for two hours from dawn, and also to record a few gulls at Lagoa de Albufeira. The beaches from Costa da Caparica to Fonte de Telha were very busy with people enjoying the sunshine, so the gulls were loafing during the day at Lagoa. However...they were almost always very difficult to observe here at close quarters because of disturbance from dogs and swimmers. Up to 20,000 gulls were present here at times...mostly Lesser Black-backed Gulls.

During the week I took 106 cr readings - including 98 Lesser Black-backed Gulls. The most amazing thing was that although these sightings included birds from Iceland, Germany, Denmark, The Netherlands, Belgium, Britain, France and Spain - the most frequently recorded birds were "Guernsey Gulls" - with 21 observations of 16 different birds.

This is clearly a disproportionately high number of Channel Islands birds and it makes me wonder whether our gulls were so common because of the western geographical positioning of both the Channel Islands and western Portugal, and also because of early migration away from the islands? Whatever the reason I was absolutely thrilled to see so many of our own birds in Portugal!

Cormorants from France

At St Saviour's Reservoir today I saw a Great Cormorant, White CI10 (red ring also) , which had been ringed on 15 May 2010 on the Chausey Islands, Manche, France (Gérard Debout). The bird has been seen several times in Guernsey  since Tony Bisson first saw it at St Saviour's Reservoir in October 2010 - most recently by Vic Froome on 20 August 2011 (when he recorded a 2nd bird from this very same cr project).

The Guernsey Seabird Team is planning to begin a new ringing project on this species in the islands next year. Our rings will be black with a double alpha code.

English Black-headed Gull and Belgian Mediterranean Gull relocated in Guernsey

I could only check about 150 of the 500 Lesser Black-backed Gulls along the west coast today, as the largest flock was resting in the long grass at L'Eree Aerodrome. The highlights of the morning were the relocation of Black-headed Gull White 21J0 (from Hosehill Lake, Berkshire, England - first seen in Guernsey at Vazon on 17 July 2011), and the regular Mediterranean Gull from Belgium (White 3E90).

A new record set for "Guernsey" LBBGs in Spain!

A new record was set today by avid gull watcher Antonio Gutierrez in NW Spain! He recorded (and photographed) six "Guernsey Gulls" on the same beach in Spain (Pantín near Valdovino in A Coruna) at the same time...I am really stunned that this is possible! This beach is over 800 km from Guernsey! When I started the Lesser Black-backed Gull colour ringing project I never imagined that such results could be obtained! One of these gulls was also the 2,000th LBBG sighting in the months of July and August 2011. Of course most were taken here in Guernsey and Alderney before the birds migrated...but there is a very nice set of records from Spain, with some in France, a few in England and the first adults are also now being sighted in Portugal.



GBBGs from France

Following yesterday's success with colour ringed LBBGs, it was the turn of GBBGs today - with four French birds on Guernsey's west coast. Three of these were from Seb Provost's project based on the Chausey islands, Manche (Green, B.17 (a 2008 chick last seen in Guernsey in October 2010), and Green H.12 and Green H.23 both 2010 chicks seen for the 1st time in Guernsey). There was also one GBBG from Gilles Le Guillou's project based at Le Havre, Seine-Maritime, but this was on the L'Eree Aerodrome where the grass is still too long to be able to read full rings. It was -3G (a 2010 chick). Hopefully I'll relocate this bird in the next few days.

LBBGs from Wales and England

About this time of year the behaviour of the LBBGs left on Guernsey changes and few seem to visit Chouet Landfill. As a result the northern beaches of Chouet and Pembroke attract relatively few LBBGs. Instead they seem to flock on the west coast (particularly Vazon, Perelle and L’Eree) - and if I time a visit well in relation to the tide (and am lucky that the beaches haven't been disturbed) this always proves to be an interesting time for as well as containing the local LBBGs which are tardy in migrating (all my birds still seem to leave the island from late October to early January), the flock clearly attracts migrant LBBGs. Today amongst 60 LBBGs at Vazon there was a juvenile bird (White 4WF) ringed on 03/07/2011 on Flat Holm Island in the Bristol Channel, Wales (Viola Ross-Smith) and an adult (Black R2LU) from the Ribble Estuary, Lancashire, England (David Sowter).

Seabird Visits 2011

Lesser Black-backed Gulls in a "Burhou" Sunset - PKV

With the 2011 Seabird Breeding Season now complete (from my point of view) I have uploaded brief reports on eleven visits to islands and islets in the Bailiwick of Guernsey this year. It was very much a "mixed" season with good productivity amongst early breeders such as European Shag and Great Cormorant, mediocre productivity for Great Black-backed and Herring Gulls and very poor productivity for my principal study species - Lesser Black-backed Gull. Despite this, mainly thanks to Paul Roper, and members of the North Thames Gull Group and the Guernsey Seabird Monitoring Team, the LBBG study goes from strength to strength with a very successful cannon netting operation at Chouet landfill in May. We failed (for the second consecutive year) to land in the main Gannet colonies to ring chicks, but did manage to ring a sample of European Storm petrels on Burhou - so a very mixed season, full of highs and lows...and as ever hard , but rewarding work!

Herring Gulls in Guernsey

On 7th August 2011, Dave Murray (who lives in NW England) visited Guernsey for the day – as part of a cruise. Dave is a keen recorder of gull colour rings, and he has seen several Guernsey birds in the Malaga region of Spain. He has also been to Guernsey a couple of times for long weekends. On his most recent flying visit he managed to record 15 locally ringed Herring Gulls and one cr Great Black-backed Gull in St Peter Port Harbour. As usual Dave very kindly sent me some very nice photos of these gulls.
