This is the smallest of our Herons, and is well known all over the country. 

 Sometimes they breed in numbers in rookeries, in company with the larger 

 Herons, but in most sections of the country they will be found nesting, one or 



two pairs together, along the border ot some 

 swamp or stream. They have a greater diversity 

 of building sites, than do any of the other Herons 

 and frequently nest a long ways from water. 

 Their nests may ;be found in alders, birches or 

 even apple trees. It is the usual Heron type of 

 platform, upon which the three to six eggs are 

 laid. They are a pale greenish blue in color, and 

 measure 1.45 x 1.10. Data. — Avery's Island, Louis- 

 iana, April 10, 1S94. 5 eggs on a platform of 

 twigs placed in a willow tree growing on tho edge 

 of a pond. Collected by E. A. Mcllhenny.
