     'l‘his " tiger among birds" is an inhabitant of heavily forested re- 
     
     gions. and is common therefore only in the wilder, less settled portions 
     
     of our country. It is the only one of our resident Owls which destroys 
     
     poultry and birds iii any numbers, but, in spite of its frequent visits 
     
     to the farmyard, Dr. Fisher considers that in many localities it is a 
     
     “ beneficial species " because of its great fondness for rabbits.

     The syllables are all on the same note, and bear some resemblance to 
     
     a bass-voiced dog barking in the distance. 
     
    

    
     A much rarer call is a loud, piercing scream. one of the most blood- 
     
     eurdling sounds I have ever heard in the woods. 
     
    

    
     "Of 127 stomachs examined, 31 contained poultry or game birds;

     “The Snowy Owl is diurnal in its habits, but like most birds is 
     
     more active in search of prey during the. early morning and again 
     
     toward dusk. Like many of the Hawks, it occupies a commanding 
     
     perch for hours, watching what is going on about it, occasionally 
     
     'arying the monotony by dropping on a mouse or launching out over 
     
     the broad country. soon to return to its perch. During its southern 
     
     wanderings it is very partial to localities in the vicinity of water. 
     
     especially the barren sand wastes along the seashore or extensiw 
     
     marshy flats bordering the bays and rivers. . . .
