Chough eye color

["Steve Read" <>]

Steve – any possibility that bird with white eyes is an adult Little Raven?

 

As I understand it, adult White-winged Choughs have red eyes, with the eyes of younger birds starting brown and transitioning with age through orange to red.

Hello birders,

Looking through our photos, I found one with interesting contrast between the birds' eye colors.

 

See the second photo for Chough at this checklist:

 

https://ebird.org/checklist/S61460739

 

Two birds there, I assume immatures, appear to have dark eyes.  The one facing the camera seems to have white eyes, not red.  Is that unusual?

 

I have read that Choughs' eyes can engorge with blood during displays and interactions.  Perhaps this individual is exceptionally serene?

 

Thanks for any thoughts you may have --

 

good birding,

Steve Johnson

returned now to the United States, no longer seeing all those wonderful birds Down Under
