Le Gabar, Le Vaill., Ois. d'Afrique, i. PI. 33. p. 136. 
The celebrated Le Vaillant first discovered this 
beautiful Hawk during his travels in Southern 
Africa, and it was subsequently introduced into his 
great work on the birds of that region. Ornitho- 
logical painting was then, however, hut in its in- 
fancy ; and we must therefore not be surprised that 
the figure which accompanies his description is very 
poor. Le Vaillant mentions several districts in the 
interior where this bird w 7 as not uncommon ; but 
remarks, that he never observed it within the limits
