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 Winter; Skeppsbron; 8th December 2018

 Caspian Gull. Delighted to find the bird still present at the site today. It gave fantastic views down to a  metre or two at times and was enjoyed by several birders whilst I was there today..


 A really nice bird this one, here at rest on the water...


 Nice comparison with 1st winter Argentatus. Note the long necked appearance here, along with the whiter head, bill shape, tertial pattern and difference in greater coverts.


 Upperparts from above in flight.


 Nice image of the fanned tail here, Again, classic Caspian Gull, with whitish base and blackish tail band. Just a mall amount of black barring. 


 In flight, note the typical greater coverts, which look darker at the bases and lack the typical triangular notches of Herring Gull.


 Very confiding today and the bird was rather aggresive at times, competing with the local Argentatus Herring Gulls for handouts. The bird was frequently to close to photograph.

 Close up of the head. The bird is a rather classic individual, probably a female. Note the rather long, parallel sided shape of the bill.

 Close up of the mantle and scapulars. Note the typical pantern on the second cycle mantle and scapulars, typical of 1st winter Caspian Gull.

 Close up of the tertials and wing covert's...

View of the underwing, typical of the secies in this plumage. Rather whitish on the underwing and not as well marked as Herring Gull. Again, a nice view of the tail here as well...

A selection of images of the 1st winter Caspian Gull, which is still present at Skeppsbron and showing very well. The bird calls constantly and this makes locating the bird extremely simple. It is a striking bird and quite easy to pick out by appearance alone, though the typical braying call really carries well and makes locating the bird among seventy odd Herring Gull very much easier. Nice to get some better images today, though it was heavily overcast on the day.
