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; A First Calender Intermedius?; 1st Calender; Skeppsbron; 20th July 2012

On the water here, an apparent LBBG, first seen at the site a few days ago- Note the small head and bill, dark feather centres on the upperparts with warm toned fringes and closely patterned flanks...




If flight here, note the large looking pale inner window on the primaries. which should appear dark on a Baltic LBBG, leading to the suspicion of a young intermedius perhaps? Other features are in line with a first calender LBBG, especially the dark marking on the underwing covert's and the tail pattern, a solid dark band with white tipped tail feathers. The greater covert's are also rather dark centred...




A nice shot of the bird on the deck, looking like a classic, young LBBG. Note the short bill, flanks, darke centred feathers on the upperparts and tertial pattern. The thighs look rather short. 

Images here of a bird which caused some confusion, due to the inner primary window in flight appearing rather pale. This leads me to the assumption that this could be a posible intermedius LBBG, not unlikely with other birds in the area at the momement. An interesting individual nonetheless, bearing more than a passing resemblence to a 1st calender Yellow-legged Gull! Features are discussed above in the captions, thanks to those who have commented on this birds appearance elsewhere...
