John started off the day well confirming that the Channel Wagtail was still in the Upper Cherwell Valley at the Borrow Pit pool and a Common Sandpiper was there too. On his way back he discovered a Grasshopper Warbler reeling away in the triangular field bounded by the M40, the canal and the railway.
In the Upper Cherwell Valley a Redshank was at the Borrow Pit pool briefly but flew off into Northamptonshire. The Channel Wagtail was showing very well with two Yellow Wagtails and I was pleased I could get a good detailed look at it.
The Grasshopper Warbler was reeling at dusk and into the night, so hopefully it stays here. It did move around the field a few times but I did get to see it briefly. As I was out I thought I would walk up the valley a bit a look/listen for owls. I didn't get any but I did hear at least one Curlew bubbling away near to the river. Walking back I couldn't see the Arctic Tern, although it was dark I'm pretty sure it had left.
I got back to the car to find someone had thrown a beer bottle through my rear windscreen. Nothing had been stolen, so I assume it was just someone drunk and either angry at the world or 'having a laugh'. Whatever it was, it ruined the end of my day. Some people do not like the Grimsbury area, or even Banbury, but I have honestly never experienced any trouble in the area until today. It won't put me off, but I will be less complacent about where I leave my car and what I leave in it from now on.
