Guernsey Gulls Annual Report

2014

Executive Summary

In what was likely to be the penultimate year of large scale gull colour ringing in Guernsey, we enjoyed another very successful year, with a total of 2,117 gulls being ringed (2,107 of which were also colour ringed). This brings the cumulative total for gulls colour ringed in the project to 11,614, since its inception in the summer of 2008.

The high annual ringing totals were once again due mainly to the week-long visit in May of a specialist gull ringing team from the North Thames Gull Group, and an excellent breeding season for both Lesser Black-backed Gulls (Larus fuscus)  and Herring Gulls (Larus argentatus), making it possible to ring a good sample of chicks for both species this summer.

With so many gulls now carrying colour rings, and with very good recording effort again this year, it was no surprise that 2014 was yet another record year for gull sightings with a total of 16,990 additions to the database. It is particularly rewarding now that many gulls are building long and complex life histories which is recording not just their breeding and feeding sites, but also their regular migration and wintering areas. Some gulls have histories involving more than 150 individual observations now.

In 2014 a deliberate decision was taken to focus on recording the breeding colonies of more of the gulls that are already colour ringed, rather than trying to maximise the catches of new full-grown gulls in the summer period. This gave invaluable data on the breeding sites for many Lesser Black-backed Gulls and Herring Gulls particularly in Sark.

Colour Ringing Gulls

The majority of full-grown gulls were once again caught during the week-long visit of Paul Roper and a small team from the North Thames Gull Group (incorporating three members of the West Cornwall Ringing Group), who teamed up with the usual small number of local gull enthusiasts for the cannon netting at Chouet Landfill from 20 to 25 May 2014. This year wet weather on several days played a significant role in reducing overall catches, as did the gulls’ atypical more cautious behaviour, but despite this the team did remarkably well. By the end 1,065 new gulls had been caught and colour ringed. This total compromised 316 Lesser Black-backed Gulls, 731 Herring Gulls, 17 Great Black-backed Gulls (Larus marinus) and a single Yellow-legged Gull (Larus michahellis).

This brought the total number of gulls colour ringed at Chouet Landfill during the six years we’ve worked with the North Thames Gull Group to 7,660 birds!

The other main ringing was on work with chicks on the various colonies around the Bailiwick. Both Herring Gulls and Lesser Black-backed Gulls were productive in 2014, making it straight forward to ring good samples of both. In total 354 Lesser Black-backed Gull chicks and 213 Herring Gull chicks were colour ringed during the summer. Surprisingly Great Black-backed Gulls appeared to have a relatively modest season, and we had to work hard to ring 58 chicks this summer.

Finally, we ran several successful Sunday morning catches in our garden mainly during the summer, boosting the numbers of adults colour ringed. However, a couple of late autumn/winter catches have proved to be very interesting as they have indicated the origins in South-west England and North-west France of many of the immature Herring Gulls that are seen in the Islands at this time, with some birds from even further afield (see Appendix Two).

Observations of Gulls Colour Ringed in the Bailiwick

16,636 observations of Bailiwick colour-ringed gulls were made in 2014. This is the highest annual total so far recorded since the projects began. Many gulls now have extensive life histories recording their breeding colonies, feeding sites and migrations or dispersals. The Guernsey Gulls database has rapidly become one of the largest such databases in Europe, and will be very valuable in the years ahead as gulls’ ecology continues to adapt to the changing environmental factors associated with food supplies and security of breeding locations etc.

While the majority of observations were reported from the Bailiwick of Guernsey, there were around 3,669 sightings from outside the Channel Islands. This included reports from Jersey, England, Wales, Scotland, Norway, Denmark, The Netherlands, France, Spain, Portugal, the Canary Islands, Morocco and Mauretania.

An overview of the observations for each species follows, and selected sightings are included in Appendices 2 and 3.

Black-headed Gull (Chroicocephalus ridibundus)

Although we have only colour ringed two Black-headed Gulls in the past eight years, we received news of one of these birds in February 2014 from its likely breeding colony at Maglebaek so, Brondby Strand, in Denmark. This gull had originally been ringed as an adult in May 2013 at Chouet Landfill and was therefore most likely not breeding in that summer.

Lesser Black-backed Gull

There were 8,522 reports of our colour ringed Lesser Black-backed Gulls in 2014, of which 5,472 were local to Guernsey. This left 410 (257 individual birds) seen in Alderney and 117 from Sark (98 birds), along with 2,523 reports involving 1,553 individual gulls from outside the Channel Islands.

The foreign sightings were 1,260 (540) in Portugal, 695 (340) in Spain, 491 (229) in France, 49 (41) in England, ten (nine) in Morocco, seven (four) in Wales, four (three) in the Canary Islands, three (single birds in each case) in The Netherlands and Norway, and a single bird in Mauretania.

Herring Gull

7,262 records of Bailiwick colour ringed Herring Gulls were taken in 2014, with the vast majority (6,303 or 87%) being local birds seen in the Bailiwick (6,092 in Guernsey, 119 in Sark and 92 in Alderney). The remaining 959 (13% of) observations came from France 741 (457 individual birds), Jersey 175 (84), England 34 (26), Spain three (three), Norway three (one), and one each from Scotland, Wales and Portugal.

Yellow-legged Gull

Given that we have only colour ringed four Yellow-legged Gulls in Guernsey it is remarkable that we received five reports of three of these birds in 2014! One of the birds was seen on the north-east Mediterranean coastline of Spain in January, before being reported from the west coast of Portugal in September, while another bird was observed twice on the same day in nearby locations in north-east France. The final bird was ringed at Chouet Landfill this May and was then observed in November at Hendaye, Pyrenee-Atlantique on the very south-western coast of France.

Great Black-backed Gull

The total of 1007 observations of Great Black-backed Gulls colour ringed in the Bailiwick was easily a record for the year. Of these 891 (88.5%) were local records in the Islands, with the remainder being seen in England 62 (32 individual birds), France 53 (eight) and Portugal one.

This species shows a distinct bias in its dispersals in a north-west direction into the south-western counties of England, with the 2014 records coming from Cornwall (15), Devon (13), Dorset (three) and Kent (one). Remarkably few birds are recorded in North-west France and this year the 53 French sightings related to only eight gulls; all of which were seen on nearby coasts except for one bird in Charente-Maritime (at 46.231 -1.501 degrees) and one at Boulogne, Pas-de-Calais (50.751 1.0585). 

The observation in Portugal is remarkable in that it is the most travelled Great Black-backed Gull ringed in the Channel Islands, and the only one reported from that country so far. Also surprising was that it was ringed as an adult believed to breed in the Channel Islands, and which had been seen in the islands on frequent occasions over several years since ringing. A photograph of the bird provided by the observer left no room for doubt as to the validity of the record.

Observations in the Bailiwick of Gulls Colour Ringed Outside the Channel Islands

Black-headed Gull

Three foreign-ringed Black-headed Gulls that had been recorded in the Bailiwick in several previous winters were once again recorded in 2014 (arriving in the islands as early as the end of July); these being two Polish and one Lithuanian-ringed birds.

Mediterranean Gull (Larus melanocephalus)

In an unprecedented late summer/early autumn for numbers of Mediterranean Gulls on Guernsey’s east coast (with numbers peaking at 71 birds in early August), five colour ringed birds were recorded. This included the two regularly returning birds originally ringed in Belgium and recorded now in several years, as well as three birds ringed as chicks this June in Somme (one) and Vendée (two), France. One of these first year birds was seen later in the winter at Porto, Portugal.

Lesser Black-backed Gull

There were 39 observations of 20 different individual Lesser Black-backed Gulls originally ringed in the following countries: - England (twelve), Norway (three), Portugal (two), and one each in Germany, Wales and France. Most of these birds were migrants passing through the islands, although the total includes some gulls that were clearly ringed on their wintering grounds and which breed in the Channel Islands, including the gull ringed in Portugal (which nests on Burhou).

Herring Gull      

Only three Herring Gulls ringed outside the islands were observed in 2014; all of them had been ringed in England in the counties of Gloucestershire, Suffolk and Norfolk (one each).

Great Black-backed Gull

268 records were taken of Great Black-backed Gulls originally colour ringed outside the islands, although this total related to only 38 different individuals. Three of the birds were long distance migrants from Norway, while the majority (27) had been ringed in France (17 on the Chausey Islands, Manche and ten at Le Havre, Seine-Maritime), with seven in England (five in Cornwall and two in Dorset) and one in Wales.

Gulls recorded on Ring Reading Trips to Portugal

In 2014 I recorded gulls in Portugal on two occasions in the autumn; firstly during a non-dedicated visit to Faro, Portugal in September, and then on a dedicated trip to the west coast of Portugal from Matosinhos in the north to Sines in the south.

During the trip to Faro on the Portuguese south coast, there were good gull flocks on the beaches and in the fishing ports, and I managed to take 219 gull colour ring reads; the vast majority of which (183) were from Lesser Black-backed Gulls, with 35 Yellow-legged Gulls and just a single Mediterranean Gull. The Lesser Black-backed Gulls came from the usual very good spread of projects run in countries from Iceland, through Norway, Denmark, Germany, The Netherlands, Belgium, France, England, Scotland, Wales, Spain and Portugal. However, the highlights were the 41 observations of 31 different LBBGs ringed in the Bailiwick of Guernsey, including one of this year’s chicks from Burhou, Alderney. Many of these Guernsey Gulls show great site fidelity to this area of the Algarve in successive autumns/winters.

When we began the colour ringing study of Lesser Black-backed Gulls in the summer of 2008, I never imagined that we would receive reports from observers of more than 100 individual Bailiwick ringed birds on any single foreign trip. In the past few years the pioneer gull ring readers Peter Rock and Harry Vercruijsse have both made separate trips to Portugal and have returned with almost 100 sightings of Guernsey birds. In fact in October 2014 Peter established a record when he came back with 102 sightings ...the first person ever to break the century mark.

 

However, with lots of fresh intelligence from Peter’s visit I managed on my dedicated gull ring reading trip to the west coast of Portugal to record a total of 156 Guernsey and Alderney-ringed Lesser Black-backed Gulls. This included a simply staggering day at Eirol Landfill, Aveiro with Tim van Nus and Pedro Moreira when we observed 61 Bailiwick birds (amongst a record-breaking day for the site of c 140 gull colour ring reads). This trip combined with increasingly regular reports from local bird watchers in Portugal, and other ring reading trips made by gull researchers from northern and western Europe, serves to highlight just how critical the west coast of Portugal is to migrating and wintering Channel Islands’ Lesser Black-backed Gulls (amongst other populations of this species)!

 

The Great Cormorant (Phalacrocorax carbo) Project

Chris Mourant and I continued our modest project on locally breeding Great Cormorants this year, with a further 31 chicks being ringed from the colonies on Herm and off Lihou Island. Although this project is on a far smaller scale than the gull research it is now beginning to yield some interesting and valuable records of the colour ringed birds. In 2014 there were ten reports involving seven birds from the following countries: - Guernsey (two records of separate birds), Jersey (three sightings involving two different birds), France (three observations of two separate birds – in Manche and Vendée), with singletons in England (Somerset) and Spain (A Coruna).

Acknowledgements

The GuernseyGulls project is very much a collaboration with Paul Roper and members of the North Thames Gull Group, who (during their annual one week intensive cannon netting visit to the Island) catch and ring the majority of new gulls each year. The work would also not be possible without the wonderful co-operation of island owners and tenants and their boat crews, and in recent years we have been increasingly grateful to the States Sea Fisheries Department for assistance accessing some of the more difficult seabird colonies for survey and ringing work.

In a world where access to landfill sites is becoming ever more difficult, we are indebted to the Public Services Department and States Works and the management and all the staff at Chouet Landfill for their very much appreciated help with (and interest in) our studies.

The Guernsey Gulls fieldwork team is small, but dedicated. I am once again grateful to Chris Mourant, Phil Alexander, Carolyn Brouard, Jamie and Mish Hooper, Rich & Margaret Austin, Vic Froome, Trevor Bourgaize, Catherine Veron, Ian Buxton and Cris Sellares for their help with the fieldwork. Roland Gauvain and Tim Morley and other staff from the Alderney Wildlife Trust staff enabled the work on Burhou to take place this year, while  Andy Cook ensured that we were once again able to cover the Sark colonies.

Given the size of the gull projects now, it is patently obvious that the projects could not continue to run without the digital databases established initially by the late Charles David and subsequently developed with a user-interface by Colin Le Conte and staff at Digimap.

As ever, I am indebted to the huge commitment that Rich and Margaret Austin dedicate to administering the Channel Islands Bird Ringing Scheme. It has to be one of the most efficiently run schemes in Europe and one now with the highest percentages of fully digitised data, making future analyses very much easier and quicker.

Finally my sincere thanks to everyone who takes the time and trouble to report colour ringed gulls inside and outside the Bailiwick.  It is wonderful that so many people contribute their records to this valuable conservation project.

(This gull was found sick and taken into care in Portugal where it was initially ringed on release. It was recorded frequently in the summer of 2014 in Guernsey, and was located nesting on Sark that summer. It has clearly made a full recovery from its illness as it has successfully migrated back to the Bailiwick again being seen at Chouet on 12 March 2015).

 

Herring Gull

 

Black JX355         4269057 ad          26/05/2013         Hornoya, Vardo, NORWAY

                                                vv           10/01/2014         Chouet Landfill Beach, GUERNSEY, 2,907 km

 

(Hornoya is a major seabird breeding site for several species high up in the Arctic Circle. This is the first Norwegian-ringed Herring Gull to be recorded n the Channel Islands, and the longest journey on record in the Islands for this species. It is clearly a Scandinavian race bird – Larus argentatus argentatus).
