After two months with very high
levels of colour ring reading in Guernsey (August and September),
things eased back
a little in October for the following reasons:-
- I was out of the island for two separate weeks - firstly with
Catherine exploring the coastline of Normandy, France, and then with
Sophie (my daughter) similarly relaxing in Brittany, France. See the
sections (to be added) for further information on the gulls seen on
- I managed to enter Chouet landfill only on three days and on one
of these visits a couple of local "cowboys" were shooting rats and
rabbits adjacent to the landfill. Not surprisingly the gulls didn't
like this very much and they never settled in the landfill until it
- While Herring Gulls remained in very good numbers, Lesser
Black-backed Gulls were scarce this month with the highest numbers
being a flock of 60-80 roosting along the island's west coast until
mid-month (when numbers fell to c 20 birds). Great Black-backed Gulls,
however, slowly increased with evidence of immigration from France and
Notwithstanding this, October proved to be a "massive" month for my own
colour ringing projects with a host of exciting reports from England,
France, Spain and Portugal. I have been very pleasantly surprised by
the high level of reporting of colour ringed gulls from my schemes.

An outstanding series of sightings included more of the juvenile gulls
fledged from Burhou, Alderney being seen in NW Spain, while adults
were reported from a couple of landfills in northern France, and then
mainly in Portugal. This included a wonderful series of observations
from Matosinhos, Douro Litoral from Malcolm Millais (seven different
Larus fuscus), and an incredible return of ten different LBBGs from
Quarteira, Algarve from Michael Davis. Salva Garcia also found three
birds in Malaga Harbour, Spain. Continuing their sterling work of the
earlier autumn Antonio Gutierrez and Paco Veiga continued to report new
Larus fuscus from NW Spain.
A summary of reports this month (which includes some birds from
September reported this month) is as follows:-
I have been fascinated to see how the vast majority of adults arriving
on the beaches of NW Spain appear to move on very quickly - some are
now being seen in southern Portugal! However, "White 9.T9" defied this
general observation by remaining at Esmelle Beach, Ferrol, A Coruna, N
W Spain from at least 02 August to 16 October - although it would seem
that even he has moved on now.
Again it is really interesting to see that the first juvenile Larus
fuscus were arriving in NW Spain by the end of August, but new juvenile
birds were continuing to arrive as late as 31 October. The autumn
migration for this species does seem to be very protracted.
Only yesterday (7th November) I saw one of the juvenile gulls
on Burhou this summer at Chouet landfill, Guernsey. I cannot think that
this bird will stay on Guernsey for the whole winter, but it will be
interesting to see when it leaves and (maybe) where it goes to?
Another exciting report was of White 8.U0 - an adult ringed on the nest
on Burhou, Alderney in June 2009, and seen by the Madrid Gull Team at
Colmenar Viejo Landfill, Madrid, Spain on three dates from 13 September
to 04 October (and then again at Pinto landfill, Madrid on 06 November).
The long series of sightings from Quarteira was particularly exciting,
as Catherine and I will be heading there in early December for
five days to try to see some of our Guernsey Gulls. Michael
Davis' observations must give us very real hope that we have a superb
chance of doing just this. There is something very special about seeing
your own gulls so far from home in the winter...and then finding them
again the following summer back on their breeding grounds.
In this context I was thrilled in October to locate along Guernsey's
west coast White 6S6
- one of
the 16 adults I had colour ringed in the summer of 2008 - but one of
only three which I had failed to relocate in Guernsey in 2009. White
had been seen on 16 November 2008 at Ria de Castellanos,
Cantabria, Spain by Jun Ma Dominguez Robledo - so it was very special
to find this gull again just before he migrates south again.
With virtually all of the local Larus fuscus gone by October it was
perhaps not surprising that a couple of foreign cr gulls were seen.
Finally (I had been looking all year!) I spotted a bird from Roland-Jan
Buis' Dutch projects. This gull (Yellow
) had been ringed as a chick at Moerdijk
(Tetra Pak) breeding colony in June 2007. I saw it a Vazon Bay,
Guernsey on 06/10/09. The other cr LBBG was a juvenile Blue VA6Y (a
Danish bird - details awaited) - seen at Chouet landfill on 24/10/09..

Grey G+M and White A6HM at Chouet landfill 07 October 2009
Although Herring Gull numbers remained high at Chouet landfill it was
noticeable that many birds dispersed quickly after feeding. The
exceptions were on days with high tide in the mornings. Gulls will then
loaf in the landfill - which makes ring reading much easier! As well as
a good number of sightings of birds from Jamie Hooper's project
(1998-2007) and my own (2009 onwards), I also saw Herring Gulls from
two other projects (both on 07 October at Chouet Landfill).
had been ringed as a
chick in Gloucester in June 2009 by peter Rock. While White A6HM
had also been ringed as
a chick, but by Richard Thompson at the Sussex RSPCA rescue
centre - which looks after injured gulls and unfledged chicks brought
in by members of the public. Over the past 12 years Richard and his
team have helped more than 3,000 gulls! White A6HM
was released on 27 July
at Pett Level, East Sussex, ENGLAND.
Many (perhaps most) local birders regard Guernsey's Herring Gulls as
being strictly sedentary, but the colour ringing programmes are proving
otherwise. Although complex the dispersal and migratory patterns of our
local Herring Gulls are now beginning to emerge. Reports are coming in
of adults ringed in the summer of 2009, which have now dispersed to the
nearby French coasts of Manche, Calvados, Cotes d'Armour and Finistere,
with some travelling as far south as Vendee, Loire-Atlantique and
Charente-Maritime. A few have also gone north and been seen in the
landfill sites in Gloucester, ENGLAND.
I was particularly thrilled to discover two of our gulls when Catherine
and I went to Normandy this month. White
and White 2.ZZ2
were seen at Le Petit Hameau, nr Ravenoville and Gatteville Lighthouse,
Manche respectively. Incredibly the latter bird was seen a few hours
before we saw it by local gull spotter Laurent Legrand!

There were three records of GBBGs ringed as chicks in the summer of
2009 moving out of the islands as follows:-
(ringed on Burhou,
Alderney on 09/07/09) was seen at Slapton Ley, Devon, ENGLAND by Brenda
Child on 09/10/09;
Crevichon, Jethou on 09/06/09) was seen on the Hayle Estuary, Cornwall,
ENGLAND on 19/10/09 by Phil Rutter; and
(ringed on Lissroy,
Lihou, Guernsey on 24/06/09) was seen at Portland Bill, Dorset, ENGLAND
on 21/10/09 by Nick Hull.
In addition I recorded six French-ringed birds in the Channel Islands
(four of which were new sightings).
and Green E.38
, ringed as chicks on the
Chausey islands, Manche, FRANCE by Seb Provost were seen together at
Vazon Bay, Guernsey on 09/10/09.
- also ringed as a
chick on Chausey by Seb, was seen by Tim Earl and me on Platte Saline
Bay, Alderney on 02/10/09.
had been ringed as a
chick in June 2005 at Le Havre, Seine-Maritime, FRANCE by Gilles Le
Guillou. I had seen this bird before in Guernsey several times between
18/09/08 and 22/01/09. It was then seen back at Le Havre on 03/07/09
and 07/08/09, before being sighted again on Vazon Beach, Guernsey on
(also a chick from
Gilles project at Le Havre) was seen at Ouistreham, Calvados, France on
02/09/09, before being seen in in Guernsey at Chouet landfill Beach on
22/09/09. It was then back on Pembroke Beach and Chouet landfill on
ringed at Le Havre,
Seine-Maritime, FRANCE by Gilles was seen on 17/10/09 at Vazon bay.

One further movement involving a Larus marinus which had been seen in
Guernsey was the thrilling sighting of Blue
on the beach at Lion-sur-Mer, Calvados, FRANCE on 10 October
2009 by Catherine and me (along with Eric Robbe). I had seen this
bird seven times in Guernsey over the winter of 2008/2009 from 04/09/08
to 26/02/09. I then saw it again on 15/08/09 at Chouet landfill.
Although it was hard to even find a Mediterranean Gull on Guernsey in
October I was very excited to see Green
on the beach at Siouville, Manche, FRANCE on 13 October -
because I had first seen this very gull on Pembroke Beach, GUERNSEY on
Details of the Polish ringed bird seen at the Mare de Carteret Castel,
Guernsey on 05/09/09 were received as follows:
Gdansk FN 63015
ringed as a
chick on 26/05/09 at Januszkowice, Zdzieszowice, Opolskie, POLAND by J
Siekiera - a distance of 1,481 km and elapsed time between ringing and
sighting 1563 days.

Sincere thanks again to all those gull enthusiasts who have made
October such a valuable month for my gull studies with their sightings
of Guernsey Gulls!
