rose in vast numbers, but without clamor, alighting on the tops of 

 the trees around, and watching the result in silent anxiety. Among 

 them were numbers of the Night Heron, and two or three Purple-

 Crows, or Gulls. She had probably perished in defence of her 

 eggs.

 make excursions up the rivers and inlets, but return regularly in 

 the evening to the red cedars on the beach to roost."
