BIRDS OF INDIANA. 967 



when the day is gone and darkness reigns, they sing on. Mr. Beck- 

 ham mentions the ventriloquial effect of their voices. When sur- 

 prised, the birds, instead of flying, run or glide through the grass, 

 like a mouse or snake, and utter a sound more like the hissing of 

 a snake than the scolding of a bird. It is said not to be difficult 

 to mistake the escaping bird for a gliding snake. The theory has

 the movements and hiss of a snake, as a means of protecting its nest 

 (Nehrling, K A. Birds, XII., pp. 149-151).
