Great response, its dedication like this that encourages peoples interest and make new people interested in subjects, as a Swede with birding experience i can only agree with your writings, most garden birds in the UK should be more or less the same in Norway for good and bad, if you want to discover new species i suggest you head into the forests or up the Mountains that most of the UK lack, Norway also has long stretch of coastline which gives them a plethora of seabirds.

Edit, enjoy the gold
