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

Great Black-backed Gull; 3rd Calender; Rästasjön; 15th January 20100

Great Black.backed Gull, the bird drinking. I aged this bird as a third calender due to the extensive dark grey tones on the mantle and scapulars primarily. The clean whitish head neck and breast also suggest a bird in the second winter of it's life. Wing covert's are second generation, as are the tertials.


Next to a second calender Argentatus Herring Gull(left). The birds larger bulk is obvious in this shot, a deeper chested and mare powerful bird. The bill is noticably heavier, depper and blunter with a more pronouced gonedeal angle...

A small looking individual. Note the pale tip to the bill. The deep chested build is obvious in this shot...


Some shots here of a 3rd Calender Great Black-backed Gull, which I picked out from the Herring Gulls at Rästasjön yesterday. Notes added below the pictures regarding main key identification features...
