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
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

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?
