White morph Grey Goshawk

["Philip Veerman" <>]

And I have seen a grey morph of the Grey Goshawk flying with Topknot
Pigeons in what may be the same behaviour or even equally coincidental.

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)
