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:

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
