I had missed the importance of CG's comment on iris colour, and will have to re-read the paper as I'm not sure why this would be the case - given that ad Caspian is said sometimes to have a pale iris and large gulls often develop pale irides from their second winter, it's not obvious to me why this would be a problem. For reference I recall pics of a spring ad Caspian Gull with a very pale iris on Steve Arlow's website www.birdersplayground.co.uk - wouldn't such a bird surely have developed its eye 'paleness' quite some time before adulthood? Plenty of food for thought, as always with gulls!Dominic Mitchellhttps://www.blogger.com/profile/10131405752512532599noreply@blogger.com
