of diminutive antelopes, and to hares, bustards, and 

 plovers ; but it also feeds largely (and, I fancy, by choice) 

 on carrion, besides which it devours fish, frogs, and 

 earthworms ; it pursues and plunders other less powerful

I have obtained examples of this species at Objim- 

 binque, the mouth of the Onanes River, Bull's Port, the
