197. Egretta candidissima (Gmel.). Snowy Heron. 

 Ardea candidissima. Garzetta candidissima. Little White Egret. 



Geog. Dist. — Formerly from Argentina to the northern United 

 States, casually to Nova Scotia, Ontario and British Columbia, 

 breeding from Virginia and southern Illinois southward. Now 

 nearly exterminated in the United States. 



Like other herons the Snowy used to wander northward in the 

 Mississippi River flood plain after the breeding season and was a 

 common bird on the marshes of St. Charles Co. in August and 

 September, but none have been seen there for the past ten years. 

 A few may have survived the slaughter and destruction of their 

 colonies in southeastern Missouri and with proper protection 

 may again become an ornament of our late summer landscape. 

 Mr. J. D. Kastendieck shot some on the mill pond at Billings in 

 August and September 1895, and Mr. W. E. Praeger reports them 

 as having occurred near Keokuk, but Snowy Herons seem never 

 to have visited the more northern and the western part of the 

 state in large numbers.
