Herons and Bitterns 



kin, the green heron is always a wermit, rarely seen in couples, 

 and never found in colonies, even at the nesting season; but 

 surely there are enough exceptions to prove the rule. From all 

 points of its large nesting range come accounts of heronries 

 where not only green herons have built their rickety platforms of 

 sticks in the low branches of trees or bushes in communities, but 

 have associated there with different relatives, particularly with 

 the night heron. They begin to build nests, or reline what the 

 winter storms have left of their old ones, about the middle of 

 April. These birds become attached to their nesting sites that 

 they return to generation after generation, and a roost often be- 

 comes equally dear. There are certain favorite trees in localities 

 where the green heron is abundant that one rarely misses finding 

 a bird perched upon. 



Why it is that the eggs — pale dull blue, from three to six — 

 and the helpless fledgeling do not fall out or through their ram- 

 shackle nursery is a mystery. Indolence characterizes these birds 

 from infancy; for they remain sitting on their haunches in a 

 state of inertia, roused only by visits of their enslaved parents 

 bringing them food, until they are perfectly able to fly, some 

 weeks after hatching.
