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

Lesser Black-backed Gull showing signs of moult; Skeppsbron; 6th August 2015

 In flight here, a little over exposed, this photo. The bird clearly not the same individual seen three days ago at the site.



 Managed to get this bird down onto the deck. The bird is a third calendar by my reckoning. Note the pale lemon bill with dark marks on culmen. Legs are greyish pink, whilst the back shows brownish tones...



 Note here the tiny mirror on P10 and the signs of moult on P1 and P2. is P2 growing out or is this arrested moult? note the dark in the central tail feathers, so clearly not the individual seen three days ago.



 The bird looked remarkably dark at times, certainly approaching nearby Baltic Gulls. At other angles it looked remarkably pale above. Still, longwinded and slim, looking as a Baltic Gull should here...



 A nice view of the inner primaries and the upper wing here.



Middle bird here, looking pale, though care must be taken as these birds can all appear very differently toneless, depending on the angle they stand at in relation to the light.

Back again today to find this 3rd Calendar bird which was showing some signs of moult. Figure this one may well be a third calendar Baltic Gull. Hopefully it will stay around and I can monitor any further signs of moult...
