Had the Black Redstart on the old college as well as 8 Purple Sandpipers in their usual spot. A Red-throated Diver and 6 Common Scoter flew north and 4 Guillemots were drifting around on the sea. It appears as if my gull from Sunday will most likely remain unidentified unless it returns. Bit of a shame really as I feel like it may have been something interesting. Maybe a hybrid or an American vagrant or something like that.
