Dull, overcast with a moderate and cool SW wind.
Today, I basically spent hours watching this thing and the 1500+ large gulls following it at Birling Gap. I was amazed not to find a single Yellow-legged or Caspian Gull amongst them but was very pleased when a dainty juvenile (2cy) Iceland Gull briefly dropped in amongst the Herring Gulls.
Iceland Gull. A really elegant one, perhaps a female.
It’s actually my first “white winger” at Beachy Head
Some interesting dark markings in the outer primaries although being confined to the inner webs, not really what you’d want to see if considering kumlieni. Only spending about 5 minutes in the field before departing east, I was unable to locate it again despite spending several hours looking through the Herring Gulls.
