;52 WARBIJ'.R SONGS. 



closely resembled the song of Chippy, but was higher pitched 

 and more deliberate. 



The birds probably .sing during their stay in the migrations, 

 but I find no record of a renewal of song on the southward 

 journey. 



Eastern United States, west to the Plains, north to Mani- 

 toba, Ontario and New Brunswick. 



Palm Warbler. Dcndroica palmaruni. 672. 



The trill remains as a prominent feature, but the note is no 

 longer a true chip. Better tsee tsee tsee tsee, with a distinct

 during the migrations. While the

Myrtle Warbler. Dcndroica coronata. (555. 



There is some variation in utterance with this species, but 

 the general effect is a trill or twitter, therefore bearing a closer 

 resemblance to the Chipp}^ than to any other group. The 

 syllable tsice repeated several times gives a fair idea of the 

 quality. 



The Myrtle Warbler is with us from the third week in 

 April luitil the third week in M.2c\\ singing constantly; and
