 Mud and Seal Islands, off the coast of Nova Scotia, westward from the 

 city of Yarmouth. The nests were all nearly alike in location, structure 

 and materials; placed a few feet from the ground, against the trunk of an 

 evergreen tree. They were composed of various kinds of mosses, a few 

 fine sticks, weed-stems and rootlets and were lined with fine bleached
