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

Yellow Legged Gull; 1st Calender; Skeppsbron

 Direct comparison with Argentatus 1st calender. note paler head with dark mask in this phot in comparison to the darker, well marked head of the accompanying Argentatus. Note also the reddish tons on the mantle of the Yellow-legged Gull, absent in the Argentatus...




 Note again the paler head. Notice the longer wings of the Yellow-legged Gull, very well documented in this useful photo...




 Slimmer build apparent in comparison to stockier, more pot bellied Argentatus to the right...




 Note the differences in the tertials, greater covert's. The whiter head and masked face again apparent, but see also the difference on bill shape, Yellow-legged with heavier, paralell sided bill, thickest at the base.




 Agressive dispaly...




Aggressive display...


 Close up here to document the new fresh scapulars. early moult is the resukt of an earlier birth date to the south...




 Again the scapulars on the right side, a few fresh feathers have now shown, moult will now be fairly rapid in the coming weeks on the mantle and scapulars...




 Aggressive dispaly, the bird showing its underwing. Note the broadly blotched breast sides and flanks...




 A view of the birds right side at close range. Note the longish legs...




 A nice view of the underwing pattern...




 Great view of the tail pattern in this shot...




 Again in flight, underwing and tail pattern on show. Greater covert's bcome increasingly dark towards the outer wing...




 Again the underwing...




 Upperparts in flight. Note the inner primaries, tail pattern, greater covert's, reddish tones on mantle and scapulars, whitish head, darl mask and bill shape...




 Compare the tertials in this shot...




The bird well able to hold it's groung amongst Argentatus....



Arrived at Skeppsbron today at 10.30am for my daily check and was delighted to see the Yellow-legged Gull was present after it's absence yesterday. Daily feeding for the past couple of weeks has seen the bird become very bold and it now comes readily to food, resulting in todays suite of photos at close range. Took full advantage of the birds willingness to perform today and spent 90 minutes photographing it for many different angles, the resuly on view above. The bird is now showing its first fresh scapulars as the moult begins...
