Common Gull, Dernford Reservoir, 11th February 2022 © Steve Cooper
'The spring passage of Common Gulls is well on the way with 400 dropping into Dernford on Friday. The photo of part of this flock has a 2cy with a clean white headed and underparts characteristics of 'Russian' Common Gull unfortunately I didn't manage to see it's underwing. The single bird photo is an example of a heavily marked bird.' SC
