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

Batic Gull; 1st Calendar in moult; Skeppsbron; 28th August 2015

 Bird A. Right side. This rather advanced bird has been in the area for some time and shows several moulted scapulars.

 Bird A. Left side. Again several upper scapulars moulted.


 Bird A. Detail of scapulars on left side.


 Bird A. Detail of Scapulars on right side. Moult is not symmetric on this individual...


 Bird B. Also rather advanced with interesting moult. Right side here.


 Bird B. Left side also shows moult in same areas.


 Bird B. A nice view of those new middle scapulars here, showing the detail on the new feathers...


 Bird C.
 Bird C.


 Bird D. Right side. The very beginnings of moult are apparent in this photo.


Bird D. Left side. Again, minimal moult, though in same area as the other side of the bird.


Alway interesting to monitor moult in gulls, though especially in species such as Baltic Gull. This species was initially not thought to moult until it reached the winter quarters, but careful observation by gull enthusiasts has shown that a reasonable percentage of bird do, in fact, begin moult before departure. The four birds above were photographed this morning in very awkward light, though a good impression can be gained from the shots taken. The upper two birds are the most advanced, though close scrutiny revealed at least sseven birds out of 15 juveniles present were showing some sign of fresh moult on the mantle/scapulars. Hope these birds hang on as late as they can in order for observations of moult progress to continue to be documented.
