Typical weather for the Bank Holiday-freezing cold northerly wind, with rain and hail coming down horizontally.
Went down to Amwell and spent most of the morning in the hide, sheltering with everyone else. The Grasshopper Warbler was reeling as I arrived, and the air was full of hirundines. A male Yellow Wagtail was a nice surprise, even more when it was flushed by a Kestrel revealing at least one female (and maybe another in it's talons). In the hide, the pair were seen frequently on the various islands, and appear to be settled.
Three Little Ring Plovers are present now, with at least one Ringed Plover and a single Redshank.
In the woods, I managed to see a Garden Warbler high in a Willow singing. The Blackcaps were of course deep in the bushes and not visible.
A single Orange Tip in a brief spell of sunshine was the only butterfly. As everyone left, a single Hobby was seen hunting over the wood.
