It was feeding on a stretch of grassy foreshore stretching westward from the Martello tower for about 200 metres
We watched it for a couple of hours but with a few good shots in the bag and with the number of birders on the beach starting to increase we decided to move on. Probably not a good idea as I didn't take another picture all day.
Just for a bit of variety, here is a Stonechat from Tuesdays visit to Waltham Brooks. We did get to see the Great Grey Shrike but I didn't manage to get a picture. The Male Stonechat was keeping his distance but the Mrs came over to have a look at us.
