popped into west rise at the end of the day. wasn't much happening with the gulls so i didn't hang around, just a goldeneye and a yellow-legged gull of note. headed back home to catch the west beach low tide roost. there was a nice flock of adult lesser black-backs and with them another first-winter caspian gull. this one with more solidly dark wing coverts and uniform pale grey saddle giving a neat contrast. three of the lessers were colour ringed (blue, green and red) but too distant to read numbers.
