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

Baltic Gull; 1st Calender; Skeppsbron; Stockholm; 3rd September 2017






































A series of images of 1st kalender Baltic Gulls from Skeppsbron today.....

Greater black backed Gull; Larus marinus; 1st Calender; Skeppsbron; 3rd September 2017


A rather small individual in the field. Note however the heavy build, a deep chested bird with a rather short primary projection and less attentuaed rear than Herring Gull. Bill deep and heavy. The head and underparts are rather whitish.  Note the crisply marked covert's, the greater covert's lacking the saw tooth appearance on Herring Gull in particular, being much more simply marked. Tertial pattern is typical of Larus marinus, with a large ammount of white at te tip and feather fringe. The photo below shows the birds bulk and thickset structure in comparison to a rather pale 2nd calender Argentatus.


Some photos and notes on a rather small Larus marinus at Skeppsbron today.

Moult in 1st Calender Common Gulls at Skeppsbron, Stockholm; 3rd September 2017

 Advanced moult in a handfull of individuals, who were no doubt earlier breeders than the majority of birds.











 This bird has recently started to moult, note the fresh gryinsh feathers here...


 Slightly more advanced that the bird above it...


 A bird still in full juvenile plumage, about 50% of the birds were in this plumage...


 The most advanced bird I was at the site today, almost in full 1st winter dress...
















A set of images taken at Skeppsbron today. I was interested in the state of moult in these birds, some of which were very advanced, whilst others had yet to commence moult. There was a nice opportunity to photograph these birds today at the site...
