Range. — North America, breeding cliiefly north 

 of the United States except in some of the higher 

 ranges along our northern border. A small Fal- 

 long, often confused with tlie Sharp-shinned Hawk, but 

 much darker and a more stoutly built bird. It is a daring species, often attack- 

 ing birds larger than itself; it also feeds on mice, grasshoppers, squirrels, etc.

 natural cavities of dead trees ; and sometimes on rocky ledges. Their four or 

 five eggs have a brownish buff ground color, heavily blotched with brown and 

 chestnut. Size 1.50 x 1.2;;
