Yes. The photo is one Chough in foreground with an adult (white
eye) and a juvenile (dark eye) Raven behind. Not sure which species of Raven,
probably Little Raven. Our Choughs are quite different to the choughs of Europe
which are corvids (crows). Our choughs are quite different to ravens. Notice
the quite different shape (including the bill). It is not really true that the
white in the wings is only visible in flight. Yes the fully closed wings hide
the white but they have many displays with open wings.

I've just had a quick list at the photo on your list, and
wonder if they could be two Ravens at the back? I forgot to note where
you took the shots though so Ravens is as close as I can suggest. The
bills, apart from the eyes, don't seem quite right for choughs.

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
Thanks for any thoughts you may have --
returned now to the United States, no longer seeing all those
wonderful birds Down Under
