The first bird was most likely a female as it was a petite individual. I was happy that all the key features were visible including quite pale underwings. The tail had a black band which tapered at the outside edge and the rump and uppertail coverts were white with a few black spots. The nearby first-winter LBBGs had brownish underwings and the rumps and uppertail coverts were dull brown with extensive spotting.

Since my last posting, some fist year Herring Gulls are starting to replace their mantle and scapular feathers, so this feature has to be used with caution now when looking for first year YLGs. Below is a video of some of the first year YLGs and a short section of the third-winter Caspian. Look out for the Suffolk ringed Lesser Black-backed Gull and the escaped White-cheeked Pintail.
