>From the close-up image of the head of this bird, it appears to me as though
the iris of the eye is possibly a yellowish colour. I agree that it appears
as though there is not much, if any, speckling in the iris of the eye - just
a basic background yellow colour.
Another point to consider here is that there are a number of medical
conditions that can affect the colour of the eye e.g. hyper-lipaemia and
jaundice to name just two. Physical injury can also affect eye colour.
Bleeding into the anterior chamber of the eye, a condition called hyphaema,
can also cause the eye to appear very dark in colour. The pupil here is
easily visible and appears normal, so I do not suspect any conditions like
lens luxation etc.

For those who did not understand what I meant about the 'dark
eye', I have posted a more close up photo here.
