Been reading recently about seabirds (esp Gannets) showing an all dark iris as a consequence of getting and surviving bird flu...
The attached sub-ad Herring Gull on my local beach in Mablethorpe, Lincs on Aug 11th shows such eyes.... not even any dark pupil visible, simply black.
At first i thought about possible Caspian genes being involved but it doesn't seem right for that.... apart from the iris it was a perfect Herring Gull, and i'm pretty sure such eyes can't be attributed to immaturity.
Not sure if any/many other gulls have been seen recently showing anything similar?
Regards
Dean
