'A 



I Pale f?reenish l^lue.) 



Range.— ^ early the whole of North America, except the extreme north; resi- 

 dent south of the middle portions of the United States and migratory north of 

 there. 



This handsome Heron is 

 about four feet in length. Its 



general color is a bluish gray, -■ ., 



relieved by a black crest, prim- 

 aries and patches on the sides, 



and a white crown. In the '^■■ 



south they breed in large 



col(jnies, often in company with \ 



many other species. In the 

 northern portions of their 

 range they breed singly or in 

 companies of under a hundred 

 individuals. They generally 

 l)lace their rude platforms of 

 sticks well up in trees, near 

 ponds, swamps or rivers, but in 

 the most northerly parts of their 

 range, where trees are scarce, 

 they often build on the ground. 

 Unless the}' are disturbed, they 

 return to the same breeding grounds, year after year. They lay from three to 

 live eggs of a greenish blue color. Size 2.50 x 1.5(1. Data. — Duck Island, 

 Maine, May 20, 1883. Threeeggs. Nest of sticks and twigs, about fifteen feet
