An old stub or branchless trunk of a dead tree standing well out 

 in a field is the kind of perch the Sparrow Hawk most frequently 

 chooses. Prom this lookout, like a Loggerhead Shrike, he awaits the 

 appearance of game below. Generally it is a grasshopper which falls 

 his victim. When he detects one, he flies directly over it and poises 

 on hovering wings until the right opportunity offers, when he drops 

 lightly downward, clutches his prey in his talons, and then returns to 

 his perch to devour it at leisure. 



The Sparrow Hawk's call is a rather high, quickly repeated hilly- 

 killy-hilly-killy, which in some sections gives it the name of " Killy 

 Hawk."
