serve the reputation commonly attributed to the large Hawks of the 

 genus Bufeo. 



The Sharp-shinned Hawk differs decidedly in habits from the 

 mouse- or insect-eating species, which watch for their prey from a 

 lookout and capture it on the ground. It is a fearless, daring, ag- 

 gressive bird, and flying swiftly, rather low, either in the open or 

 through woods, it makes sudden dashes at the frightened birds, which 

 hurry to cover to escape its talons. One hears a commotion among 

 the birds ; calls of alarm, and a dark form darts through the foliage 

 in close pursuit, or, missing its aim, alights in the center of some 

 thickly leaved tree, there to await in silence a fresh opportunity. 

 Sometimes it may be seen soaring in narrow circles, when its dispro- 

 portionately long tail forms a good iield character. 



It is usually a voiceless bird except during the nesting season, when 

 a too close approach to its nest causes it to utter its peculiar notes.
