308 LIFE-HISTORIES OF BIRDS 



A beautiful fabric before us is deserving of a pass- 

 ing notice. Its base and the greater part of its 

 periphery are constituted almost exclusively of 

 floriferous stems with dried flowers intact, of Tri- 

 folium repens, which are rather compactly adjusted, 

 and cause the nest to resemble, e?cternally, tJie 

 typical structure just described, with this unim- 

 portant difference, that the palisade-like arrange- 

 ment is restricted entirely to the inferior two-thirds 

 of the nest, while the remainder is rather neatly 

 composed of the flexible culms of grasses, and the 

 inner bark of Quercus rubra interwoven so as to 

 present a rounded edge interiorly. The inside is 

 very uniformly lined with black horse-hairs, ex-

The eggs are oblong-oval, and marked with 

 ferruginous-brown upon a whiteish clay-color, 

 which in some specimens are arranged about the 

 larger extremity; and in others are so diffused as 

 to impart a rusty color to the entire ^g'g. They 

 measure .70 by .51 of an inch. 



Zonotrichia albicollis, Bonap. 



The White-throated Sparrow has proved itself 

 to be a not very abundant species in Eastern 

 Pennsylvania during its winter stay. It makes its 

 appearance about the 20th of April, and is always 

 to be found in company with leucophrys. It fre- 

 quents low, damp woods, in rather retired situa- 

 tions. Like the latter it is rather tame, and can 

 be approached with considerable ease. Its general
