Fig. 222. 



Among the hawks the sharp shinned is a veritable bushwhacker. 







His light body, short wings, and long tail enable him to double and 

 turn among the brush and branches, and in a noiseless, fox-like way 

 pounce over a hedgerow or brush heap into the midst of a flock of 

 sparrows, swoop under the low branches and pick his bird from the 

 ground, or dart through the treetops and snatch one in mid air from 

 the midst of a startled nock.
