562 bulletin: museltm of comparative zoology. 



was indeed surprising to find the Oven-bird in such damp situations. 

 On many occasions throughout the month of July, I heard the ringing 

 call of the Oven-bird arising from impenetrable masses of stunted 

 spruce and juniper. It would be interesting to know if this dark, 

 damp environment has not had some direct influence on the change 

 of coloration of this subspecies. 



Seiurus noveboracensis noveboracensis (Gmelin). 

 Water Thrush. 



Eight adults of both sexes from Deer Lake and Nichols\'ille, June 

 26th to August 3rd. 



Water Thrushes were found abundantly in all the wooded regions, 

 especially in the vicinity of streams. 



47. OpORORNIS PHILADELPHIA (Wilsou). 



Mourning Warbler. 



Six adults of both sexes from Nicholsville, Port au Port, and Spruce 

 Brook. 



Although this bird was not abundant, it was seen on several other 

 occasions throughout the month of July. 



48. Geothlypis trichas brachidactyla (Swainson). 

 Northern Yellow-throat. 



Two adult females from Lewis Hills and Spruce Brook, August 25th 

 to September 10th. 



Both of these specimens are distinctly darker than any fall birds 

 of this species from the mainland. But knowing how many other 

 Newfoundland birds show only tendencies toward a darkening, I do 

 not feel inclined, without further material, to describe the Newfound- 

 land bird as a race.
