Bonaparte's Gull and Beaver

A morning surveying with Russ in Dorset today started well with a Red Kite en route at 06.05hrs SW over the A3052 near the Beer turning which had presumably roosted nearby.

After the survey we decided to take a 10 mile diversion to Longham Lakes where the Bonaparte's Gull performed very well. I'm certainly no gull expert, but although it looks very much like an adult it does have a black strip on P9 and some black markings on the primary coverts/alula area which would make it a 2nd Summer or 3rd Calendar Year. This would also fit as I believe it is a returning bird from the previous year when it was a 1st Summer. It spent most of its time harassing a group of Tufted Ducks and stealing molluscs from them as they re-surfaced. It would then carry the mollusc off in it's crop to presumably later break the shell undisturbed.

This evening a walk along the Otter was worthwhile as I saw only my second Beaver sighting of the year, a young animal (without ear tags) from last year. The previous sighting was on 30th April this year and was the green tagged male.
