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; 3rd Calender Year; Skeppsbron; 31st July 2017

 A rather interesting 3rd calender LBBG. The rather advanced moult drew my attention. Note the newly grown P1-P3, with both P4/P5 both dropped. This bird was photographed by Dirk Van Gansberghe at this site in June and had just begun to moult the innermost primaries at that point, thus the bird has been actively moulting these past several weeks. Since that time around 60% of the median covert's have been replaced with new feathers, but the tail remains the same.


 This shot of the uppreparts cleary shows the full extent of moult in this individual...


 On the deck the bird appeared rather heavy chested and had a slightly shorter primary projection than many of the nearby Baltic Gulls, prompting me to wonder whether this is in fact an intermedius LBBG. There is no way of knowing if this is the case on appearance at this point. Nominate fuscus can show moult to P6 at this time of year also...

 Interestly, this bird had brighter bare parts and bill in June. Note the remains of a thin dark band on the upper mandible, pale iris. There is also much moult apparent on the head of this bird...


Another flight shot...

A few images and some thoughts on this interesting 3rd calender Lesser black backed Gull from Skeppsbron today...
