BIRDS OF 



Nest among the rushes. 



Eggs, 3 to 5 ; white with a bluish tinge. 



This diminutive Bittern, though seemingly slender, and tender, 

 is not only generally distributed in Southern Ontario, but has been 

 reported by Professor Macoun as " common throughout the 

 country" in the North West. At Hamilton Bay it is a regular 

 summer resident, raising its young in the most retired 

 parts of the marsh. The nest is large for the size of the bird, 

 a platform being made for its support by bending down the 

 flags till they cross each other a foot or more above the water 

 level. The whole affair is very loose and readily falls asunder 

 at the close of the season. The Little Bittern is not supposed 

 to be as plentiful as its big brother, but from its retiring habits 

 may be more so than we are aware of. It is seldom seen ex- 

 cept by those who invade its favorite haunts ; when disturbed 

 it rises without note or noise of any kind, and with a wavering 

 uncertain flight passes off for a short distance and again drops 

 among the rushes. It arrives about the end of May and leaves 

 early in September.
