 in Barbary, and it wo'Jd appear that it also exists in Arabia and Persia. 

 It has been found in Louisiana, the Floridas, Carolina, and at Hudson's

 rocks, a flat nest about five feet square where it rears the young, M-hose 

 operations it also directs during their adolescence. Its eggs are of a brown 

 red, M'ith blackish stripes. It is particularly fond of hares, which form its 

 principal food It also preys on various birds, and even on lambs. The
