100 The Wilson Bulletin — No. 99 



these two small flycatchers are not reliable. Personally I 

 know of no working- ornithologist who attempts to distinguish 

 between Traill's and Alder Flycatchers in the field. 



Similar remarks may be said to apply to the attempt of the 

 average observer to distinguish between Philadelphia and 

 Warbling Vireos in life under normal field conditions. 



Another record which needs confirmation is that of the 

 Bohemian Waxwings on so late a date as May 22. The 

 birds were in all probability Cedar Waxwings.
