the addition of the fur and hair of the smaller animals. The eggs were four in num-

 small blotches and dots of purplish-brown and lilac, forming a crown around the 

 larger end. 



645. NASHVILLE WARBLER. H clminthophila ruflcapilla (Wils.) Geog. 

 Dist. Eastern North America to the Plains, north to the Fur Countries, south 

 in winter to Eastern Mexico and Guatemala. 



The Nashville Warbler breeds from the Northern United States northward to 

 Hudson Bay and interior British America. Throughout New England it is a com- 

 mon summer resident, breeding in any suitable locality in the latter part of May and 

 in June. At this season it may also be found in Michigan, Wisconsin, Northern 

 Illinois, etc. The nest is placed on the ground and is composed of leaves, bark 

 strips, sometimes almost entirely of pine needles, the lining being finer material of 

 the same with grasses and hair. Often the nest is embedded in the ground flush 

 with the surface, and it is usually hidden under a tussock of grass. The ground 

 color of the eggs varies from white to creamy-white, and are speckled with minute 

 dots over the surface, but chiefly at the larger end with reddish-brown, hazel and 

 lilac. They are three or four in number and have an average size of .64x.45 inches.

 Ridgw, Geog. Dist. Pacific coast of North America, eastward during migrations 

 to the Rocky Mountains, northward to Kadiak, Alaska, and southward to Lower 

 California and Western Mexico. 



This bird is very similar to the Nashville Warbler and its nests and eggs 

 probably identical.
