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

Probable Intermedius Lesser Black-backed Gull; Skeppsbron

 The bird at rest. The bird was picked up in flight easily due to the moulting inner primaries. A different bird to last weeks individual, this bird also noticably lighter than local Baltic Gulls, again heavier than local birds and rather pot bellied and less attenuated. The legs rather dull mustard yellow. There is obvious moult taking place on the innermost covert's. Note the inner wing coverts are moulting, the pale bases of the secondaries showing through.

In flight, extensive moult in progress, on the left wing P1-2 have been regrown and P3-4 are fresh and growing out. On the right wing P1-P4 are new or growing out, P5 possibly dropped, whilst P6-P10 are older generation feathers. Moult is not mirrored and equal on both wings as this bird demonstrates.Note the very worn tail on this bird, very heavily abraded....

Shots here of another light mantled fuscus type (graellsii/intermedius)from Skeppsbron, the second bird within a week. Owing to the dark upperppart tone this bird looks good for intermedius.Came across this bird whilst studying the local Baltic Gull for signs of moult on the wing, dicussed in the post below.
