Van Rossem ^^ recently has brought up again the question of the 

 relationship of the eastern and western groups of wood pewees by 

 listing the western wood pewee as Myiochanes virens richardsonii. 

 That the two wood pewees are so closely similar in color and form 

 as to be distinguished at times with difficulty in museum skins is 

 easily apparent, but that this is external resemblance without closer 

 relationship than that of distinct species seems evident to me from 

 knowledge of the two in life. After a familiarity of many years I 

 am convinced that they are distinct, as indicated by entirely differ- 

 ent voice. In this regard it is only necessary to consider the close 

 resemblance of females of the blue-winged and cinnamon teals as a 

 related case. With the teals the males are entirely different, so that 

 there is no confusion. With the wood pewees the sexes are alike, so 

 that the two are separated with difficulty. 



NUTTALLORNIS BOREALIS (Swainson): Olive-sided Flycatcher 



An adult male was collected at 5,000 feet elevation on Cosby Knob 

 in the Great Smoky Mountains on June 19. Another was seen at 



« Birds of El Salvador. Field Mus. Nat. Hist., zool. ser., vol. 23, 1938. p. 371.
