KUMLIEN'S FLYPAST

The first winter Kumlien's Iceland Gull gave us a flypast today giving good views of the 'venetian blind' effect on the primaries caused by the darker outer webs to the outer primaries, which also gives the wings a concolorous effect compared to a first winter glaucoides Iceland Gull. We had four out of five Iceland Gulls today, the fifth was on an awayday to Holmethorpe  http://holmethorpe.blogspot.com/
