Leucistic Herring Gull (larus argenteus)

These images were taken yesterday (31st January 2010) at Rainton Meadows DWT, this bird is a Herring Gull presumed (larus argenteus) with leucism, these are certainly the best shots I have ever seen of a Herring Gull with leucism.

Note: The brownish tones to the primaries on this photo, clearly visible as the bird rests. Also overall the bird is very white and any markings appear to be unevenly spread through the body; on the scapulars some markings can be seen but note the pure white greater coverts with no markings at all.

Note: Again some uneven brownish tones on the secondaries and primaries of this bird, also no mirrors at all on this bird. Underwing also showing very brownish tones throughout.

Note: Although fairly difficult to see on these images there appears to be brownish/buff markings that almost form a subterminal band on this birds tail.

Note: My subterminal band comment can be seen more so on this shot.

So this bird is just a leucistic Herring Gull, I would love to see this bird and get some pics of my own and some video. Its not the thought Iceland Gull by the finders but what a superb looking bird, quite a stunner! If that can be used for Gulls, I believe it can.

Until next time, Foghorn out!
