OF EASTERN PENNSYLVANIA. 23 



deciduous leaves, remnants of dried plants, sedges 

 and grasses intermingled with twigs, and lined 

 with finer grasses, sedges and strips of bark. The 

 nests are 3 inches in height and 5 inches in 

 diameter, with a cavity 3*^ inches wide by i^ 

 deep." 



The young birds are readily domesticated and 

 become quite cheerful and playful ; but are so 

 uncleanly in their habits as to make not very 

 desirable favorites. 



When the nest is visited, these Thrushes silently 

 retire to a short distance ; but when it is assailed 

 by the hawk, both birds unite to drive away the 

 intruder, uttering all the while "loud and clear 

 chirps and peculiarly twittering sounds." 



The eggs vary in length and measure on the 

 average .82 with a width of .62 of an inch, and are 

 of a uniform bluish-green hue. 



Turdus fuscescens, Stephens. 



The Tawny or Wilson's Thursh as this species 

 is popularly designated, revisits us not earlier than 

 the middle of May. Being of a retired disposition 

 and chiefly a frequenter of copses and open fields, 

 its presence is not ordinarily observed in situations 

 which its congeners love to visit. 



Its flight is moderately elevated and tolerably 

 well-sustained. Its habits whilst feeding are both 

 terrestrial and arboreal. In this respect it differs 

 materially from Pallasii and approximates musteli- 

 nus.
