After it singled out a Kit, the Skua kept chasing until the Kit finally regurgitated right by our boat.
The Skua pouncing on the prize.
This bird appears to be a third-summer, pale morph. Not a full adult as there is a pale panel mid-wing created by pale barring on coverts and also some pale barring on the tail coverts. Quite a late bird as most Arctic Skuas have now moved through.
