[Note. There are many Herons* eggs of the abOTe color, but they are all >• 1.26 long. 

 There are also many white eggs, tinged with blue (or green), and perhaps among them should 

 be included those of the Goshawk and Cooper's Hawk. Many Ducks* eggs are strongly tinged 

 with blue, green, drab, or yellowish. Most of them are laid on the ground or in hollow trees, 

 but all are more than an inch and three fourths long. The only Ducks commonly breeding in 

 Massachusetts are the Dusky Ducks, who build on the ground, and the Wood Ducks, who 

 build in hollow trees.] 



* There is no authentic record of the breed- t There are no good reasons for beliSTing 

 ing of the Bam Owl in Massachusetts. — that the Blue Grosbeak has eTer bred in Maa-
