     This species resembles the Red-eyed Vireo in habits, and Mr. Brew- 
     
     ster writes that its song is so nearlr identical with the song of that spe- 
     
     cies “that the most critical 0 11‘ will, in many cases find great difficulty 
     
     in distinguishing between the two. The notes of plularlelp/ticus are 
     
     generally pitched a little higher in the scale. while many 01' the utter- 
     
     ances are feebler and the whole strain is a trifle more disconnected. 
     
     But these differences are of a very subtile character, and, like most; 
     
     comparative ones, they are not to be depended upon unless the two 
     
     species can be heard together. The Philadelphia Vireo has, however, 
     
     one note which seems to be peculiarly its own. a very abrupt, double- 
     
     syllabled utterance with a rising inflection, which comes in with the 
     
     general song at irregular but not infrequent intervals. I have also on 
     
     one or two occasions heard the male when in pursuit of his mate utter 
     
     a soft 71.30110, similar to that sometimes used by l'ireo olivacr’us, and 
     
     both sexes when excited or angry hare a harsh. petulant note exactly
