Hi Keith,
just a quick note. I recently saw a grey Grey Goshawk flying with a
group of S-c Cs at the northern end of the Royal NP............ (just
south of Sydney, NSW)

Hello everyone, How many of you have seen the white phase of the
Grey Goshawk flying with a flock of Sulphur Crested Cockatoo. I saw
it once when I lived in Baulkham Hills, the goshawk leaving the
flock and perching in a photographic position for me. HANZAB
mentions this behaviour but gives no reason for it. Last Thursday at
my home I watched a group of ravens harassing a white bird which I
called immediately a white goshawk.due to the harassing actions of
the ravens. It perched high in a tree above the house and I ran in
to get my camera and took a couple of shots. I did not have my bins
handy so could not confirm the ID of the bird as it was very high,my
wife confirmed it with her bins.As it left the tree chased by the
ravens I immediately said to my wife that's not a goshawk its a
cocky as the flight was that jerky flight often performed by S C
Cockatoos during short flights and is very characteristic of this
species. However I was not convinced and had a look at the pics and
there it was a white phase of the Grey Goshawk. My Qs is could it be
that flying with other white birds is a hunting ruse to surprise its
prey and could this mimicking of the flying action of the SCCockatoo
be to the same end. Anyone else wittinesses these two behaviour
patterns ?
