Non-adult Ring-billed Gulls Larus delawarensis
North America, various dates

 

THE gull most likely to be seen in urban settings across North America, the Ring-billed Gull is a widespread species that many people will be very familiar with. Increasingly identified in the UK (where it was first identified at Blackpill, Swansea Bay, in 1973) it is thought that some birds regularly move back and forth between Europe and North America, and it is likely that there is now quite a sizeable population in western Europe where it is surely likely to breed any year soon.

These photos show non-adult birds, and the range of plumages they can display.
