Prairie Warbler 



Dendroica discolor 

 Like the Sycamore Warbler the Prairie is often absent for 

 years. In the two last springs, I looked in vain for this species; 

 and even when I find it, the number of records is always small. 

 My own experience is not exceptional, for other observers in our 

 locality have the same story to tell of this warbler. 



Kentucky Warbler 

 Oporornis formosa 

 Only once have I ever had the pleasure of seeing this beautiful 

 warbler. It was on the first of May, after a snow-fall the night 

 before. The brid was on the ground in a lilac hedge, where it could 

 be seen well. Such a record as this makes the ornithologist eager 

 to find so rare a warbler again. 



Canadian Warbler 

 Wilsonia canadensis 

 Arriving late in May, this warbler may be seen many times in 

 a walk. Its markings make it one of the easiest to recognize, and 

 the bird not unfrequently feeds and sings in bushes or low trees. 

 The song is one of the loudest and most elaborate of the warbler 

 performances. 



Wilson Warbler 



Wilson pusilla 



Some seasons this species is rare, but late in May 191 7 it was 



very abundant. It fly-catches in low situations, where it may be 



seen to good advantage. This warbler is a constant singer, and the 



observer must learn to distinguish its note in spite of himself. 



Oven-bird 

 Seiurus aurocapillus 

 The Oven-bird appears here only in May or at the end of 

 summer. I have often wondered why this species is not found 

 breeding in our locality. Perhaps the woods here do not afford 

 suitable nesting-sites for the Oven-bird. I made half-a-dozen 

 records of the bird in the spring of 191 7, but on no day was its 

 song heard. 



Louisiana Water Thrush 

 Seiurus motacilla 

 A single record of this warbler, early in June, was the only 

 time I saw the Louisiana Water Thrush in the spring of 191 7.
