This >|>i-.-ir> n M-inl>lr.- the Hnl-cvfcl Virco in huliits, and Mr. Brew- 

 stcr writt-s that its <ng iss<> lu-urly identical with the song of thatspe- 

 httt the most critical our will, in many ca*.s, find great difficulty 

 in dhtingvWliBg IK-IWCCII the I\M). Tlie notes nf jihilmlrljihirtm are 

 generally pitch^l H little higher in the scale, while many of the uiter- 

 ire feeliler and the whole strain is a trifle more di>c<>nnccted. 

 Hut these differences arc of a verysuhtile < haracter, and, like most 

 comparative one-, they are not to IK- depended U|MHI unless the two 

 an !* heard together. The Philadelphia Vireo has, however, 

 one note which -<i in- to he peculiarly its own. a very abrupt, double- 

 syllabled utterance with a ri.-ing inflection, which comes in with the 

 gnu nil song at irregular but not infrequent intervals. I have also on 

 one or two occa-ion> heard the male when in pursuit of his mate utter 

 a soft itxriio. Minilar to that soinetinn-s n-cd by \'irn> ulirnri-us, and 

 both sexes when excited or angry have a harsh. jH-tulant note exactly 

 like that of T. </'/'<" (Hull. Nutt. Orn. Club, v, 18W1. p. 5).
