Hello Stephen, and others,
Thank you very much for all your information. This has turned out to be a more
interesting subject than I had expected.
I have had an email from a chap who lives near Victor Harbour. He assures me
his birds have yellow eyes. But according to Schodde & Mason, Victor Harbour
birds are subsp. rosinae which are at best White-browed but have "faint dusky
spotting" on the breast - call them what you will, which poses an interesting
question - where does the changeover from yellow to blue (in adults) occur? or
is it even gradual!! I think not.
It will be interesting to learn what Norman, Christidis & Schodde have to say
on the subject. It is a very complicated issue - takes up three pages (169-171)
of discussion in Schodde and Mason.
Cheers
Graeme
