Goshawk/Sparrowhawk ID: Addendum

["Greg & Val Clancy" <>]

Hi Evan,

I have examined the photos and am confident that the raptor is a Collared 
Sparrowhawk for the following reasons:
The brow ridge is not very prominent and the bird appears to be staring;
The legs appear too long and thin for a Brown Goshawk;
The plumage suggests a bird moulting from juvenile to adult without the 
immature plumage of the Brown Goshawk;
If the prey is definitely an escaped Cockatiel the size of the raptor in 
comparison is likely to be too small to be a Brown Goshawk.
The best ID characters - the long central toe and the square tail are not 
visible in the photos.
Stephen Debus has also seen the photos and agrees with my ID.

Regards

Greg Clancy
