I decided to look at the Little Marlow Gravel Pit gull roost this afternoon and almost the first bird I looked at was an adult winter MEDITERRANEAN GULL. First seen on the far side of spit right of island looking from the bench on the west side, it later washed and then flew to spit on right of island when I lost it at about 4pm.
Immature PEREGRINE spooked everything shortly afterwards and took a couple of half-hearted passes and then flew off east.
5 Little Egrets were roosting on the same branch right of the island at 4:30pm, although I didn't see any of them fly in (Adam Bassett)
