An hour spent at Grimsbury Reservoir in Banbury early evening was very rewarding, with excellent views of two birds I've not seen there before.
For some reason I usually walk around the reservoir in an anticlockwise direction, but this evening I noticed a lot of black-headed gulls around the south west corner so I decided to go there first and continue clockwise. I soon heard the distictive "teu" call of a wader and located a redshank on the concrete shoreline. I managed to get quite close, then it flew a short distance to roost on the floating pontoons. I was an immature bird, judging from the slighly paler orange red legs (adults are more vivid) and well spotted wing coverts.
