of species. The heron typically engages 

 in this activity during resting periods, 

 after feeding or after long periods of 

 strenuous activity. These birds perch on 

 trees in the natural environment, though 

 they also utilize other structures 

 (pilings, rock outcroppings, etc.) when 

 available. Local ornithologists have not 

 located the heron population within the 

 inner portions of Boston Harbor. 

 However, during a tour of the harbor 

 several roosting areas within the harbor 

 were observed. 



Specific roosting areas appear to be 

 located within Boston Harbor, 

 particularly in the inner harbor, during 

 the non-breeding season: typically, late 

 August through early April. The physical 

 characteristics of these areas consisted, 

 principally, of timber wharves which were 

 abundant throughout the harbor.

During a site visit to Tudor Wharf, 

 approximately 13 black-crowned night

 existing Tudor Wharf (warehouse) 

 building. The timbers supporting this 

 building were densely spaced, and not 

 uniformly distributed. The pilings 

 appeared to serve as the principal 

 roosting sites for the herons. Cross-
