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.

Baltic Gull? 2nd Calendar; Skeppsbron; 19th August 2015

 A confiding bird up on the shark at Skeppsbron...


 On the water with a 1st Calendar Herring Gull


 Detail of the upper parts here. It is obviously in active moult, as is to be expected in the age class


 Detail of Tertails and Primaries, rather damaged and worn...


 Detail of the head..note the yellowish tones near the tip of the bill, lightened iris and moulting mantle and scapulars.


Above and below; In flight it became apparent the bird was in a rather advanced state of moult, with P1-P2 being newly grown out second generation remiges. P3 is growing and P4 has been dropped. The older 1st generation P5-P10 are old, worn first generation feathers. Moult seems advanced for Baltic Gull, though I do wonder whether birds in this age class can show advanced moult during late summer and autumn, unlike the adult birds?

Baltic Gull; 3rd Calendar showing three moult cycles in primaries

 A third calendar bird present today showing three moult cycles in the primaries. P7-P10 are clearly first generation feathers, pointed tips, faded and worn. These would of been the birds first juvenile primaries. P5-P6 are clearly fresher, rounded feathers from the second moult cycle. P3-P4 have been dropped and the inner P1-P12 represent the newest, freshest feathers in the wing, having just grown out. 
 Note here the moult in the tail, with fresh white feathers breaking the dark tailband. Also the bill is quite like that of an adult. Outer greater coverts have been dropped also. Moult wise, a very complex bird..



Another angle on the wing to view the primaries here...

Shots here of a very interesting bird from Skeppsbron, a 3rd Calendar showing a clear example of three moult cycles in the wing. This bird must of arrested its first juvenile moult at P6, for whatever reason. The third moult cycle has now begun...
