The plumage of the adult in fall and early winter differs from 

 the spring livery, as described above, only in having the ash-gray, 

 and also the white of the abdomen, slightly tinged with brownish. 

 The young in first autumn are essentially similar to autumnal 

 adults, but have the brownish wash or discoloration more distinct, 

 and the markings consequently less sharply defined. 



The Sycamore Warbler is a common summer resident in the 

 bottom-lands, where, accordmg to the writer's experience, it lives 

 cliiefiy in the large sycamore trees along or near water courses. 

 On tliis account it is a difficult bird to obtain during the breeding 

 season, the male usually keeping in the topmost branches of the 

 tallest trees, out of gunshot, and ofteu, practically, out of sight, 

 although liis presence is betrayed by his loud, very unwarbler-like 

 song. The song of this species is so much like that of the Indigo 

 Bird that it requires a practiced ear to distinguish them ; the tone 

 is remarkably similar, but there is a difference in the modulation 

 wliich after one becomes thoroughly acquainted with it renders it 

 distinguishable. In its motions, this warbler partakes mucli of (he 

 character of a creeper, often ascending or descending trunks of trees 

 or following their branches, much in the manner of a Mniotilta,
