Gulls are not easy to id. Better have a large group of them to see the comparision. In HK, Heuglin's Gull is the commonest, followed by Caspian (Mongolian) Gull. Vega Gull also occur in very small number. They are good to study.

I think these are all Heuglin's Gulls. An adult, a second-winter and a first-winter (in that order).
