7.0 Night Herons in Boston Harbor 



During a site visit, a group of Black 

 Crowned Night Herons was found roosting 

 (perching) in and amongst the pilings 

 under the pier deck. The following 

 section outlines the nesting and roosting 

 characteristics of the night heron and 

 the effects the construction and proposed 

 uses will have on the night herons. The 

 full report can be found in Appendix B. 



7 . 1 Description 



The black crowned night heron is a medium 

 sized heron, growing to about 26 inches 

 in length. The crown, back and shoulders 

 of adults are black, with the remainder 

 of the wings and tail ashy-grey. The 

 undersides are whitish, legs are yellow 

 and the irises are a conspicuous bright 

 red. (See Exhibit 28) 



7.2 Feeding Habits 



Black crowned night herons most commonly 

 feed in tidal creeks, the edges of ponds 

 and swamps with standing water. They 

 usually feed singly, often in areas 

 several miles from the nest. They feed on 

 a wide variety of aquatic organisms, 

 including fish, amphibians and 

 invertebrates .
