I have probably only encountered Grey-phase
birds in the Royal NP, but I think I had one at one time somewhere in between
(like grey phase but with all white head and more whiter belly). Have seen both
Grey (male) and White-phase (female) together on a nest, south of this NP at
Bulli Pass. Have also seen both phases together (a breeding pair?) at
Mitchell Park at Cattai on one or two occassions. Other areas in Sydney
where I have seen white-phase birds is at Toongabbie, (Nurragingy Reserve)
Doonside and I think there is also a regular bird around
Greystanes.
