The ornithological highlight was a singing Marsh Warbler (myrsanger) but it really had me going for a minute. It was singing on the edge of a wood and 5 metres up a tree. Marsh Warblers aren't supposed to do this! This is where you find Blyth's Reed (busksanger) and finding one in Maridalen has been top of my wish list for the last month! But I had to accept it was just an out of habitat Marsh - maybe this is even rarer than a Blyth's ;-) This bird was singing 250metres from where one has been singing in more typical habitat for a week and could very well have been this bird moving around a bit.
