On Monday two different ‘white’ gulls were seen on the Hebs and prove to be an interesting comparison.
The first was a large Glaucous Gull at Siadar. In Iain Macleod’s cracking photo you can see the bulk and hefty structure of the bird as well as the pink parallel sided bill with it’s dipped in ink tip.
The other shot is of a Kumlien’s Gull taken by Brian Rabbitts at Aird an Runair by the RSPB Balranald reserve in North Uist. Kumlien’s are the Nearctic form of the Iceland Gull (treated by some variously as a form/sub-species) and turn up annually on the islands. Nominate Iceland Gulls are more regular on the islands however.
On the Kumlien’s note the lighter structure, all dark bill, darker tail band and cream ‘dark’ colouration running along the length of the primary feathers.
Three very instructive photos of an often troubling trio.
