Gannets can recover from bird flu but are left with black irises rather than the normal bright blue.

That is really strange. Interesting, but strange.

I wonder how eye colour will be perceived by the birds, Gannets mate for life and over time black eye colour might be perceived as superior to blue or vice versa. It could be that birds who can recover from bird flu are seen as better mates and these birds will be more successful in passing on their genes.
