12 The Oelogists' Record, March i, 1922. 



I watched these birds for nearly two hours so as to make sure of 

 the species. 



The following year I visited the swamp at an earlier date — the 

 25th May. Within a few feet of the place where I had found the 

 nest the previous season, I flushed a bird that proved to be of the 

 same species,possibly one of the same pair, or maybe their descendant. 

 There was a nest in the same situation, the only difference being 

 that this nest, besides the dried grass, contained some rabbit's 

 fur for its lining, and there were five instead of four eggs as on the 

 previous occasion, at this date quite fresh. I found another nest 

 at the end of May with four eggs, which I fancied belonged to the 

 same species, but unfortunately I could not get a good view of 

 the bird. Since the year 1913, however, I have neither seen nor 

 found a nest of this warbler ; nor, for that matter, of any other 

 warbler within the limits of the swamp. They seem to have 

 abandoned it, or perchance have died out in the general diminution 

 of many of our Canadian birds. In the year 1914 there was not 

 a warbler of any kind to be seen, and when, in 1919, in company 

 with Mr. E. Beaupre, of Kingston — an ardent student of bird life — 

 I again visited the swamp, with the exception of a Mourning 

 Warbler, we failed to see any others. 



The Nasb-"ille Warbler breeds commonly in this swamp. In the 

 year 1907 I found no less than four nests, not far from each other. 

 I had with me a small net — a kind of butterfly net — with which 

 to capture and have one of these birds in hand. I succeeded in 

 doing so, for it was not a difficult matter, and this device left no 

 possible doubt of the species. The bright yellow underparts, along 

 with the ashy-coloured head, at once identified the species. The 

 bird thus caught acted strangely ; I shall never forget the circum- 

 stance. When I released her she flew round and finally alighted 

 upon my shoulder. I held out my hand and presently she flew 

 on to it and remained there for a few seconds, ther she perched 

 upon my head, ultimately flying awa}^ into a near-by shrub. The 

 last time I visited the swamp in 1919 all we found was the nest 

 of a Blue Jay with well-fledged young. 



Until recent years the Prairie Warbler had not been detected 

 as far east as Toronto. It is due to Mr. W. E. Saunders, of London, 

 Ontario, that a knowledge of its range has been extended. In 

 the year 1918, along with him and Mr. E. Beaupre, I visited the
