Hi Greg and all
Not sure on any scientific basis either but I have seen a white morph Grey Goshawk flying with a group of Sulphur-crested Cockatoos around the Dungog area. The presumption being they are using the cockatoos as camouflage to “sneak” up on unsuspecting prey. Maybe other people have had similar experiences.
Cheers
