16 Jun 2026 · LondonObserver description: It was bobbing up and down in the water looking around and had a spotty grey face/neck, after a few minutes it dived and we didn’t spot where it came up Observer notes: He was bobbing watching the folks on the bridge. So a cross between swinmming and interacting really. We didn’t see which way he was going as despite looking for ages, when he dived we didn’t see him again
