Colour Ringed Gulls

An evening visit to Little Marlow GP was somewhat uneventful.  There was clearly a passage of Swallows, Willow Warblers, Chiff Chaffs and a single Common Sandpiper, plus 10 Teal was an increase on recent days.
On checking the gulls, a mixture of Black-headed, Herring and Lesser Black-backed Gulls, I came across two colour ringed birds.  Both of these are Little Marlow regulars.

Lesser Black-backed Gull "Yellow H.581"

Lesser Black-backed Gull - Two rings on tarsus.  Black on right and White on left with letters "WO" in red letters.
