inland lake. The nest is roughly constructed of small sticks, loosely 
put together. The eggs are from three to four in number, of a pale 
bluish green color.

Herons is flagging and laborious. I have been amused to see a 
Humming-bird chasing a Heron, — the minuteness and arrowy

and other species of Heron intermit this laborious motion, and sail 
swiftly and gracefully on balanced wings, particularly when inclining

to fly, the Green Bittern seeks to escape by running, which it does
