Juvenile Gull

Took the ferry from Cairnryan to Belfast this morning (fortunately I had booked Stena, as P&O are currently not running the Larne ferry, having broken the law by sacking 800 employees without proper consultation).
A nice calm day, saw some porpoises and lots of guillemots on the water.  There were black guillemots (tysties) too as well as gannets, cormorants, and eider ducks Today's blip is a juvenile gull (I think a common gull, but I find the juveniles hard to tell apart). Extras are: a guillemot in summer plumage, a guillemot in winter plumage, an eider duck and a cormorant on a channel marker buoy.   Cormorants are remarkably colourful when seen in good light, their feathers have a sheen like that of a starling.
