Re: Re:[Birding-Aus] Brown Goshawk/Collared Sparrowhawk?

["Greg & Val Clancy" <>]

The following is Stephen Debus' opinion on the goshawk/sparrowhawk photos, 
which agrees with my opinion:
Hi Greg,

The first photo shows the upper bird to be undoubtedly a Collared
Sparrowhawk, and all the photos of the upper (adult) bird look like
Sparrowhawk rather than Goshawk.  The juvenile is of course a Brown
Goshawk.  This case is one of a Sparrowhawk (probably female from the
size and square rather than notched tail) interacting with a Brown
Goshawk.  It certainly happens, when Sparrowhawks territorially evict
Goshawks.  I think I reported such cases in my study of Sparrowhawks years 
ago.
Cheers,

Steve
