The Nashville Warbler, althouiijh an abundant species, is not very 

 T'egular in his visits to this part of Ontario, being sometimes with us 

 in considerable numbers during the season of migration, and again 

 being almost or altogether absent. When they pass this way in the 

 spring, a few pairs usually remain over the summer with us, but the 

 greater number go on farther north. In the fall they are again seen 

 in limited numl:)ers, working their w&y southward in company with 

 their young, which are distinguished by the absence of the crown 

 patch. In this part of Ontario, we never see so great a number of 

 ^Varblers in the fall as we do in spring. Either they are less con- 

 spicuous on account of the time of their migration extending over a 

 longer period, or they have some other return route by which the 

 majoritv find their way south.
