Oarzetta candidiasima Bonapabte, Conspf. II, 1855, 119. 

 Popular synonyms : Little White Egbet. Little Snowt Hebon, 

 Little Egbet. 



I include this species simply on the authority of the following 

 reports of Mr. Robert Kennicott and Mr. E. W. Nelson. Mr. 

 Kennicott includes it in his "Catalogue of the Animals Observed 

 in Cook County, Illinois,"* with the comment "common." He 

 also marks it with an asterisk which, as I understand his use of 

 the mark, indicates that it is "known to nest in Cook County." 

 His note is under the name "Egretta candidissima, Gmel. White 

 Heron." Mr. E. W. Nelson says that the Little White Egret 

 is "much less common than the preceding {Hcrodias egretta). 

 Occurs at the same time." Mr. Robert Ridgway says :f "This 

 beautiful Egret occurs during summer in various parts of the 

 State, but probably not abundantly except in the more southern 

 portions." 



Its range includes the whole of temperate and tropical America 

 from the British Possessions on the north to Chili and the 

 Argentine Republic on the south.

Formerly a common but now a rare summer resident, arriv- 

 ing early in April. A favorite nesting site of this species is in 

 the heavy bushes bordering the rivers. It departs for the winter 

 early in September. 



Its range includes the whole of temperate North America 

 from Ontario and Oregon on the north to Central America and 

 the "West Indies "on the south.
