Alan Dalton post's birding diaries and original artwork from Sweden. Established in 2006, this now long running blog is now a complete overview of my birding experiences. As an artist I greatly enjoy sketching birds in the field and you will find a wide selection of that work here, from fieldwork to finished paintings. I am very passionate about my artwork and try to depict birds in their natural habitat, as I see them in the wild. My artwork is for sale and can be viewed at http://www.alandalton.net/
As regards to my photography, since 2008 I have used a Nikon D90 DSLR camera coupled with a Sigma 150-500mm OS lens for since March 2012 for bird photography, all previous images being digiscoped. Regarding sound recording, I have been usung a Telinga Stereo Dat Mic and parabol to record birds in the field, coupled to a Marrantz 661 digital recorder, a superb piece of kit. Interest in butterflies, dragonflies and damselflies has recently seen the accquisition of a Sigma 150mm macro lens. I hope you enjoy the blog and please feel free to leave comments or contact me at alandltn@gmail.com

Caspian Gull; 1st Calender; Skeppsbron; 22nd September 2010

Caspian Gull, the second bird onsite this month....



The bird in flight with a Herring Gull. Note the pale head, advanced moult on the mantle and scapulars, the greater coverts forming the classic panel and lacking obvious notching and the whitish tail with demarciated dark tail band...










A couple of useful shots of the bird in the same frame as Lesser Black-backed Gull and Herring Gull. The paleness of the head and neck are obvious. Also noe the rather long necked appearance of the bird in the lower shot. The bill is notably long and paralell sided without an obvious angle at the gonys. Advanced moult again a major feature...





The bird left side. Notable are the pattern on the new scapulars, not perhaps classic Caspian in that they are not solidly marked at the centre, though perhaps are a little worn. Note the dark chocolate centred tertials and delicately marked greater covert's.





The underwing remarkably pale, another pro Caspian feature. The inner primary pattern on the upper primaries on the upperwing are well seen here. Innerwing primary panel not as obvious as on Herring Gull of the same age...





A useful shot of the upperwing ant tail pattern...





Again a decent shot of the upperwing...



Caspian Gull, a second bird for the site this autumn. A first calender bird found by Björn Phragmen yesterday evening. A small and probable female. A pleasure to see this bird today on the way to work, the bird immediately found onsite and came to bread. At this stage it is probably fair to say this bird may prove to be regular at the site in September, albeit just numbering a few individuals each season.

Greetings from Rome. Interesting pictures! Will there be a new Caspian gull at Skeppsbron every week? Lucky you! Cheers. Dirk VG

Hi Dirk, nice to hear from you. Was nice to get another on indeed, whilst they are still rare I would say that these birds are most frequent in September, if only a handful of individuals are involved. Possibly range expansion might see more birds turning up in the coming years? A nice bonus bird before I go to Falsterbo, a weeks birding to look forward to there which I am really looking forward to. Bringing a laptop so will publish photos as the week progresses.

Best Wishes,

Alan.

Hi Alan,

There are just 3 previous records in Uppland before 2009 (data from http://svalan.artdata.slu.se/birds/ ).
So with 3 birds (2 Stockholm + 1 Uppsala), 2010 is a very good year!

Best wishes,
Benoit
