Kumlien's Gull at Balranald, North Uist 31 March 2013

I was walking back along the track at Balranald after a brief view of the Harlequin Duck when a white-winged gull caught my eye. A few more shots of Iceland Gull in flight I thought as it approached. Through the viewfinder I did a double-take when the contrast between the outer and inner primaries indicated it was more likely a pale Kumlien's Gull. Switching to bins quickly to confirm this as it flew past before it disappeared south across the machair. Very exciting to see this sort of thing unexpectedly, but just like the Ring-billed Gull in Dublin it turns out that it had been seen in the area previously...
