May. The nest, as is nsual in this family, is a rude 

 platform of sticks and is placed in a bush or the lower 

 branch of a tree, often overhano^ino^ the water. The eerffs 

 nund)er from three to six, and in color are pale green- 

 ish blue. The young, although born with a covering of 

 hairlike feathers, are quite helpless and are reared in 

 the nest. Adults have the crown and back dark, glossy 

 green, the neck reddish brown. 



The notes of this little Heron are a clear whistle and 

 a harsh xqu<ncl\ uttered when it is frightened. It then 

 seeks refuge by alighting in a distant bush or tree, and 

 with upstretched neck and twitching tail watches the 

 int]"uder. 



The Xight Heron, or Squawk, doubtless owes its 

 escape from the fate of most Herons to its nocturnal 



habits. These birds arrive from the

rookery not far from ]S"ew York city 



being inhabited by at least one thousand 



pairs. It is in a low, wooded tract, and the nests are built 



in the trees at an average height of thirty feet. The eggs 



number four to six, and in color are pale bluish green. 



At night, while feeding, these Herons are doubtless 



distril)uted over a wide area. When flying, they often 



utter a loud squavil^ the origin of one of their common 



names. It is a surprising sound when heard near by at 



night, and has doubtless aroused the curiosity of many 



persons who live near a line of flight followed by these 



birds in going to and from their nests.
