Site Description
Brush Island, located just offshore from Little Harbor in Cohasset, is a rock island that is the site of one of the state's largest Double-crested Cormorant rookeries. It typically supports nesting cormorants and gulls.
Current Conservation Status
There is a potential for recreational boaters to disturb the colony, but there is little likelihood of development.
Ornithological Significance
One of the top four coastal nest sites for Double-crested Comorant (747 pairs, 1994) during the Massachusetts Coastal Colonial Waterbird Inventory, exceeded only by Milk Island (Rockport), Middle Brewster Island (Boston), and Weepecket Island (Gosnold).
Other Flora or Fauna of Significance
None described.
