I thought it was red-eye caused by flash and didn’t really think it important. Mind you to be sure one might request a photo in daylight but Rufous would be asleep with eyes shut. Drat. 🙂

Louis, Neil explained as much at the earlier thread as follows:
OK. So what colour are its eyes really?

Jennifer, surely you are not suggesting that I would misrepresent the integrity of my subject matter with, say, digitial manipulation?
Pressed for time, I present my full collection of rufous owl eye-shots without changing any colour.
The iris is yellow and the red is the reflection of the flash from the lucidum tapetum behind the owl’s retina.

Addendum.
So he still hasn’t answered my question. 🙂

yes I read that too but modern cameras have a setting for avoiding red-eye effects – my old analog Olympus had that facility so I assume signficant progress must have been made since that model with digital cameras.

We wait with anticipation!
The eyes (irises) are yellow, but then I thought I had already answered that question.
Which means two of us might be having temporary bouts of Alzheimers 🙁
Thanks Neil.
Or perhaps I wasn’t understanding what had been most clearly written and shown by Neil!
