During a walk round this morning, decided to take the path through Cogan Wood. First encounter was a nice Red Admiral, although it had lost part of each hind wing. Best surprise was hearing an unfamiliar song, which turned out to be a Marsh Tit singing up in tree. I’ve only ever heard the “pitchu” call before, but this was a fairly rapid “seew seew seew seew seew seewv …”. Promising sign tho’ – a pointer to possible breeding – there’s certainly a pair resident even tho’ they’re not always obvious.
