The nest of the Olive-back is placed in low balsams, spruces or beeches 



from 4 to 15 feet from the ground. It is composed mostly of mosses, 



dead leaves and plant stems, lined with dark rootlets. The eggs are 



greenish blue, spotted with reddish brown, 3 or 4 in number, and average 



.90 by .64 inches in dimensions. The nesting season varies frorti June 5 



to July 20.
