hey Tom,
I haven't got any images showing this nor have I seen any on-line. 
But yes I have noticed it before in the field in very young birds, especially 
up here. Due to being rather diligent in checking all marked birds closely for 
any vagrants, I've seen this a number of times in juv Silver Gulls...
martin cachard,
