Fowlmere visit

Sorry posted this attached to another thread as couldn't find how to start new one (until today)! A lovely few hours at Fowlmere this morning (6th). Had a good view of a mink along the nature trail path which I then saw head along the stream Several woodpeckers - green & great spotted. 4 teal at the main hide. Any reports of bitterns at the minute? -i could have sworn I heard a boom (just by spring hide -looking towards the main hide) just briefly and enough to wonder if I imagined it. I also spotted a pair of bullfinches. Always lovely to see the barn owls at least one visible at the nest box.
