1897. O.A.Lothrop told me that he examined ten nests of the 
Jan.51. Green Heron which contained eggs or young one day last spring. 
They were all in maples in the southern part of Maple Swamp, 
near Heron Pool. He brought me one nest with a fine set of 
five eggs. Passing around Heron Pool to-day I counted five 
nests of this Heron scattered about over an area of an acre or 
two, all in maples at an average height of about 20 ft. This 
comes pretty near being a colony of Green Herons. They did 
not breed so numerously in any part of the Fresh Pond Swamps 
. thirty years ago. Lothrop says that about all the nests are 
found and robbed by boys.
