I tried a new site today, just over the "border" in Wiltshire (but closer for me than many Oxon sites). My main target was Jay, as this is a bird I've never photographed before. After a fair wait, one duly appeared - just as I was packing up to go!
Supporting cast included at least two Water Rails that were pottering around in a remarkably fearless manner for prolonged periods.
There were also plenty of the common tits, including Coal.
