I wasn't going to post regarding that after today's trip as I feel weary thinking about it. I missed the bitterns by a few seconds as I got into the hide and they didn't come out for the rest of the day. i then walked nearly twenty minutes back towards the end of the park before realising I'd left my rucksack in the tern hide. Then I had to walk as quick as I have done for some time to get the train and made with twenty seconds to spare. No bramblings, kingfisher, bitterns or anything else I could have seen if I'd made the much shorter (and cheaper) trip to Moor Green.
Boo hoo hoo, sniff.
One of the old hands in the hide also said other bitterns might have been seen on White Swan Lake which has got a more extensive reed bed which also has jetties poking through it for the fishermen, so may offer some very close, if somewhat unexpected, views.
Although we did see a great crested grebe catch three fish in five minutes - one was pretty big...
