GREY FALCON. 
“ Type, South Australia. 
“ Gould figured the bird from West Australia beautifully in his ‘ Birds 
of Australia.’ This plate he afterwards cancelled, and later figured the birds 
collected by Captain Sturt at the Depot, South Australia. Those who, 
like myself, have the cancelled plate, can see the difference by comparing 
the two.” 
I have observed that this species seems nearest to the Banner Falcons 
with which it was placed by Gurney. Bonaparte, following Gould’s first 
impression, associated it with the Gyr Falcons. It has little, if anything, 
to do with these, seeing that the structure of the feet is the same as that of 
the Banners.
