hares, rabbits, mice, frogs, lizards, serpents, and insects. It 

 flies with considerable rapidity, but buoyantly. Although 

 nowhere very common, it is generally dispersed. It nestles

 broadly elliptical, of a bluish-white colour, an inch and three- 

 fourths in length, an inch and a third in breadth. Of the 

 young, which resemble the female, the male assumes the 

 adult plumage at the first moult in its second autumn.
