At last!! - Finally connected with LESSER SPOTTED WOODPECKER this morning after more than 2 years of looking - A male flew across the "Scrape" into Garden Wood at Tyttenhanger GP.
Have also put in a bit of time recently looking for Marsh Tit in Coppice Wood. No luck I'm afraid. It looks as though this site has joined other sites in Herts in losing this species (Steve Blake)
