Listowel seems a favorite locality with the "Warblers, and Mr. 

 Kells evidently gives them some attention, for this is another species 

 which he found breeding in a low, swampy, mixed bush not far from 

 his home. Mr. Kells found a nest placed between a slender limb 

 and the trunk of a small cedar about five feet up. Another was

 short duration, and when it goes the collector considers the Warbler
