On June 21, 1883, while at the spruce bush collecting, 1 heard the 

 loud song of what proved to be the Chestnut-sided Warbler from a cer- 

 tain grove of tall poplars. The specimen collected was a male ; length, 

 5; stomach full of small insects; evidently it was breeding. It is a true 

 Warbler, being seen and heard continually among the trees. Its choice 

 of locality usually causes it to be found chiefly in half-open woods, es- 

 ])ecially along the edges of low, marshy places. While singing I have 

 always observed that it kept among the branches of the taller trees. 

 Its song is somewhat like that of the Orange-crowned Warbler. I can 

 recall it to mind by the aid of the syllables " Chip-c, chi2)e, chipe^ 

 chip e, chip e, wai chip^^'' the single emphatic syllable near the end be- 

 ing the most tangible difference. 



June 10, Duck Mountain : The Chestnut-sided Warbler is quite com- 

 mon in this wooded region, and is, no doubt, breeding here. It fre- 

 quents the tops of the highest trees, and from time to time utters, with 

 little variation, the already described song.
