Another good little gulling today with the crew and also pleased to welcome Matt Phelps this morning.
Juvenile Iceland Gull (Could well be the bird seen in late November and also on the Thames, see Josh's Blog HERE). The very contrasting white primaries are pretty distinctive.

The guys also had the juv Glauc today and another Yellow-legged Gull. See Kojak's blog HERE
Juvenile Glaucous Gull- a very large individual. Found by the Dave. The first one this year at the farmlands.
We had two Caspian/Caspian-type Gulls (Here's one from yesterday, which looked similar to one we saw today)
Caspian-type Gull (right of centre) The second bird today.
Third-winter Yellow-legged Gull (left hand bird).
Juvenile/First-winter Herring Gull, the dark large bird suggests origins from high latitudes . Also had a couple of adult type argentatus.
First-winter Common Gull, the heavy streaking on the head (including the crown and ear coverts), the sparsely marked upper tail coverts, restricted black on outer retrix and relatively pale underwing (below) indicates nominate canus.

Been working through unidentified photo specimens from the summer and updating my Beddington Farmlands pan-species list HERE with the help of I-SPOT HERE. I make it 43 new species for my personal list this year including White Stork which takes my bird list to 218 (We lost the bird list league table when Johnny went awol but I think Garry is on 225, Johnny was on 219 and Roy was 215- so I think I'm third in the game). As far as I know 1211 pan species at the farmlands is the record but then again I'm the only one in the entire universe who is counting!
Will need to get round to updating the official Beddington Farmlands List HERE which on the last count was 2029 species (last updated in July 2015)- so must be getting towards 2100 now?
The most recent lists can be found here using the Biodiversity drop down menu HERE. All will need updating at some point.
Here's a few distinctive species from the specimens:
Welsh Chafer
Black-clouded Longhorn Beetle
Neetle Groundbug
Twin-spot Centurion
Thanks to Chris from I-spot for the identifications.
Following Adriaens and Gibbins 2016, this adult Common Gull keys out as nominate L.c.canus with the diagnostic suite of features as follows 1) p9 without obvious white tongue-tip, 2) p5 with broken black band, 3) p7 with white tongue tip, 4) p8 with grey at base of outer web and 5) p9 mirror larger than black tip.
Still on the look out for a 'Russian Common Gull' L.c.heinei
Cormorants at the farmlands can either be Continental Cormorant P.c.sinensis or Atlantic Cormorant P.c.carbo. Atlantic Cormorant has been confirmed by a ringing recovery. According to Constantine et al 2012 a 72 degree gular patch angle (the angle between the gape line and the gular patch to the base of the lower mandible) is just within range of either with carbo gular patch range 38-72 and sinensis 66-111 degrees.
(NB: Not sure I've measured angle accurately as haven't got a protractor and had to make one from printing one out and then trying to judge angle through paper and back light of computer- can anyone measure it more accurately?) .

Things 'escalated fast' with long term friend and work partner Holly this year. Had a great year with days out and exploring in the new camper van.

Been spending more time at Holly this year and well happy with my new local patch- Otmoor RSPB
Biggest surprise of the year was this little fella
OTHER BITS
Published the second part of New Directions in Birdwatch magazine this year.
A perceived momentous year on the Great Lie Front. Even more reasons to ignore those muppets and keeping building an alternative advanced society.
New Gear this year included a Phoneskope adaptor, 100-400mm Canon lens, a few new books, new owling spotlight and a new tripod head for doing some more video stuff
