THE TENNESSEE WARBLER. 115 



end, more sparsely elsewhere — with pale brown and purplish. 

 They measure about .67 by .50 of an inch. The number of spots 

 varies greatly in different eggs. 



Variety lutescens, No. 68^-, is the Pacific Coast form of the 

 orange-crowned warbler. Captain Bendire describes the eggs as 

 pinkish white, "spotted principally about the larger end with fine 

 dots of reddish brown and lavender." While they thus agree 

 perfectly in color with the eastern variety, in size they seem to 

 average considerably smaller. Henshaw found this bird numerous 

 on the island of Santa Cruz, breeding early in June. 



69, THE TENNESSEE WARBLER. 

 HELMINTHOPHAGA PEREGRINA {Wils.) Cab. 



This warbler is a northerti breeder so far as is known, no nests 

 having been discovered south of Massachusetts, north of which it 

 resides throughout eastern British America. Little is known con- 

 cerning its nidification, which does not differ from the other mem- 

 bers of tiiis genus. One nest obtained at Springfield, Mass., is 

 described by Mr. Brewster as built in a low clump of bushes just 

 above the ground. "It is well made, woven of fine hempen fibres 

 of vegetables, slender stems of grasses, delicate mosses, and other 

 like materials, and very thoroughly lined with hair. It measures 

 2 3-4 inches in outside diameter and 2 in height." Another nest 

 from Lake Superior in the Smithsonian seemed to have been built 

 on the ground. 



The eggs measure about .64 by .50 of an inch and are broad, 

 pyriform and opaque white, marked around the large end only, with 

 the merest points of dull red, many in number but so minute as 

 hardly to be visible ; they look more as if they belonged to one of 

 the Empidonaces or to a Vireo.
