THE TENNESSEE WARBLER. 129 



H. celata is one of the rarer migrant Warblers, of which comparatively 

 little seems to be known. In its breeding haunts, which extend up to well 

 within the Arctic Circle, it is found to be a bird of the undergrowth and open 

 thickets ; but during its migrations it is at least as likely to be seen in the 

 tree-tops along with the stricter denizens of the woods. A few of us report 

 seeing the species every year or so, and a conscientious shot every fourth 

 year confirms the record. 



Dr. Wheaton once came upon a male in full song. He describes the 

 notes as loud, emphatic, and rather monotonous, consisting of the syllables, 

 chicky-tick, tick, tick, tick. Professor Lynds Jones renders the song, chee, 

 chee, chee, chw, chzv, and says that the first three syllables are rapidly uttered 

 and the last two more slowly.
