answering each other from all points of the Glen, at distances 

 varying from one to three or four miles. 



Their chief haunt is a long stretch of wood on the south 

 side of the strath, but during the day they sometimes sleep 

 among the alder clumps which margin the loch, and in thick 

 holly trees scattered up and down the woods. 



Snowy Owl {Nyctea scandiaca). 



This bird is given entirely on the authority of a friend, on

 I was rather inclined to suppose at first that what he saw
