2cy Yellow-legged Gull - the regular bird with aberrant bill
Male European Stonechat
The river held comfortably the highest number of Herring Gulls that I've recorded here so far - around 350. Unfortunately nothing could be found among them and the party was ended prematurely when a Common Buzzard went low south-west, flushing them all.
I decided to stay in on Sunday morning in order to get some work done. Bad decision - before I knew it, David Campbell was doing damage at the wetland centre with Iceland and Caspian Gulls. I spent the rest of the afternoon working the river, dodging the at times biblical rain showers, and saw little more than the usual two Yellow-legged Gulls - the aberrant bird was observed on the river for the first time near Hammersmith Bridge while the regular bird at Chiswick Eyot was showing well.

A visit to Beddington Monday morning was productive with six Caspian Gulls (four 2cy and two 3cy), including the pallid, yellow-ringed 'X319', which was seen on the Thames in East London by Rich et al on numerous occasions before it became regular at Beddington.

A quick check of the gulls along the Thames between Fulham and Chiswick in the afternoon produced very little, aside continuing Dutch Black-headed Gull 'EE5T' and a German Common Gull, 'ALJJ'. This bird was ringed as pullus on Heligoland in summer 2015 and mine is the first sighting of it since!
