I was in two minds about going this evening but as I drove back into Banbury I could see some large gulls flying in and decided to have a look. It turned out to be quite productive with c. 350 Lesser Black-backs in total, including some very dark birds that are probably of the race intermedius. Amongst these were four adult or near adult Yellow-legged Gulls and at least two Herring Gulls. A couple of birds turned up quite late and due to my inexperience, failing light and most birds actually leaving I didn't quite work out what they were. One was a second or third calender year Yellow-legged or Herring Gull, which had very smart grey mantle and scapulars but hadn't yet moulted much else in the wings. The other could have been a juvenile Yellow-legged (but was probably not going on my recent experience!).
