368 BIRDS OF ONTARIO. 



the spring of 1885, when I observed a flock of fifty or more feeding 

 in a clump of willows overhanging an inlet of the Hamilton Bay. 



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 

 found in a hemlock at an elevation of fourteen feet. The nests were 

 built as described above, of rather small size, the interior being only 

 about two inches in diameter by one in depth.

 land, the Barren Grounds 'and Alaska, breeding from Northern New England

The Black-poll is a regular visitor in Southern Ontario in spring 

 and fall. Tt is the last of the family to arrive from the south, being 

 seldom seen before the 20th of May. Its stay at that time is of 

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