Glaucous and Iceland Gull at Shawell

This morning didn't start to plan, as I was expecting sunshine not fog.

Nevertheless I set off to Shawell. The gulls were obviously lost in the fog somewhere, as there were none in the sand quarry. There was a few at the A5 Lagoons and I managed to read three colour rings including a re-read of the Herring Gull that was my 1000 colour-ringed gull at Shawell.

I moved back to the sand quarry opposite Gibbett Lane mid-morning and some gulls had gathered there. The first scan revealed nothing unusual, but as I scanned back to the left I picked up a juvenile Glaucous Gull. It was paler than the one I saw last week. Its bill lacked a fine pale tip, so it should be a second calendar-year bird.

Something spooked the gulls and they all took off. Amongst those that eventually returned was a juvenile Iceland Gull.

Steve Nichols managed to arrive in time to see the Iceland Gull, but another chap arrived too late to see it. Shawell is a very difficult location to twitch gulls, as the area they use is large and they are mobile. I do so well because of the time I put in and because I wait for the gulls to come to me.

I have now found 14 Iceland Gulls at Shawell and 15 Glaucous Gulls. In total I have seen 16 of both Iceland and Glaucous Gull there.

Romanian Caspian Gull Gallery

I'm really pleased with the results from my trip to Bucharest. It was very educational, especially as I was able to study the behaviour of the Caspian Gulls in their natural domain. Unlike in England there were sufficient numbers to study them behaving as they do with their own kind.

For anyone interested I have created a gallery of images - click on LINK below:

A Trip to Romania to See Some Caspian Gulls

The challenge of identifying Caspian Gulls is understanding how variable they can be and understanding features that may be OK but could also be a result of hybridisation. 

The problems is that they are not all text book specimens. Many, especially females, have unremarkable length bills and legs and they are not all snouty.

The closest Caspian Gulls to Britain come from the German mixed gull colonies, so we receive a few challenging individuals here and if you are not careful you can become become paranoid.

Anyway I decided to go further east after travelling to Germany last April. I chose Bucharest in Romania and I wasn't disappointed. Dawn and I stayed in the Herastrau Hotel in the Hesrastrau Park. A large lake in the park attracts many gulls.

It had snowed for 14 hours before our arrival, so the park looked as pretty as a picture. During our four day stay we never left the park apart from to visit another park across the road. As well as the gulls there were plenty of woodland birds including five species of woodpecker and I scored with Pygmy Cormorant, which was a lifer. The park was large enough for us to walk 11 miles one day.

The Caspian Gulls put on a fine show and as well as getting lots of pictures to help unravel the complexities of identification I also got some stunning sequences of them fighting.

Glaucous Gull

It was blowing a gale today when I stopped off at Shawell on my way to Northampton. Most of the gulls were hunkered  down in a field very close to the village. I stopped briefly and managed to spot a large adult male Caspian Gull amongst them. I didn't hang around, as it was very windy.

I moved to the lagoons where there was only about a 100 gulls on the water and most were mobile due to the wind. I almost left straight the way, but I decided to see if any gulls were on the bank. The gulls were strung out in a line towards the bank and the last one was a mighty juvenile Caspian Gull.

Yellow-legged Gulls (Larus michahellis)

Since 2013 I have been studying and photographing Yellow-legged Gulls at Portimao, which is in southern Portugal. The fish harbour there attracts many gulls and they are generally quite confiding and allow close approach.

Amongst the gulls are some tricky individuals that don't quite conform to the rules. The first-winters can be very difficult to separate from Lesser Black-backed Gulls. Some of these are not typical of the nominate Larus michahellis michahellis and a few may well be L.m lusitanius, or be closely related.

For anyone with an interest in these gulls I have put together a gallery of images.
