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

Argentatus Herring Gull; 3rd Calender; Skeppsbron; 26th October 2010

The bird here in flight showing the upperwing. The bird can be establish as a third calender due to the white tipped P5-P10, the dark markings on the primary covert's, markings on the wing covert's and the residual tail band most obviously...



The underwing in flight. note the at the legs appear dull pinkish as one might expect of Herring Gull.

The bird landing on the water. A reasonable view of the primary pattern here. Interestingly the iris still appears rather dark on this individual...


At rest on the water. This photo shows the short winged appearance of the bird, despite p10 being fully grown on the outstretched wing, which point to Herring Gull. The bill is rather yellowish towards the tip, the remainder darker, though the base is also starting to lighten...



Wing Detail.
(a) The outer primary(P10) is white tipped with a dark line separating it from a large white spot which is mainly withing the inner web of the feather, though does extend on to the outer web. The extreme outer edge of the feather is dark. The remaining visible P10 appears largely dark...
(b)The next primary inwards(p9) also his a white spot at the tip, with another smaller white spot plainly visible on the dark primary not far from the tip. Again the visible part of the feather is wholly dark, though the inner third appears greyish here...
(c)A white tip is also present on P9, with the outer third appearing dark. A dark trailing edge is noticable, as is the dark primary shaft..
(d)P7 is white tipped with a broad dark subterminal band that extends up along the outer web. There is also a whitish crescent betwenn the dark and grey..
(e)P6 is also tipped whitish, or "mirrored", with a broad dark subterminal band, which only extends along th outer web a small distance...
(f)P5 is tipped white with a rather narrow subterminal band which narrows toward the feather shaft and possibly just adjoins there




An Argentatus Herring Gull here from today, a third calender bird. I took a range of shots of this individual with a view to dissecting the plumage details here,...
