26. [191] Ardetta exilis (Gmel.). Least Bittern. 



Rare migrant. One was taken alive and kept in the laboratory for 

 a week in May, 1902. It was fed small fishes, which it swallowed 

 readily. Its appetite was amazing but was the cause of its death. A 

 large mass of fish bones became stuck in its oesophagus and put an 

 end to his gastronomic feats and to his career.

28. [196] Herodias egretta (Gmel. ). American Egret. 



Rare migrant, not observed since 1887. "The earliest record for 

 Indiana is that given by Prof. Evermann from Bloomington, April 10,

 1886. C. H. Bollman called it a rare transient in 1886, but makes the 

 remark that it might be added to the list of summer residents as he 

 had taken it July 29, 1885. It has also been taken in this county by 



I. N. Corr and S. E. Meek.

Edmonsbn found a colony of ten or twelve nests in a small clump of 

 cedars near the water-works reservoir. June 3, 1901, a nest was found 

 in a small cedar, about 50 yards from a pond. It was 25 feet high' 

 in a dense thicket of small trees. The nest was poorly made of sticks and 

 the eggs were visible from below. There were 5 eggs. On June 11 

 these were hatched, and on the 19th the young were well covered with 

 down and were hopping around among the branches (W. L. H.). May
