Toronto about the third week in May, and in the fall they some- 
times become very abundant, choosing usually willows near the 
banks of a stream. I have seen such places alive with these birds 
from 2Ist August to gth September. (/. Hughes-Samuel.) A 
rare migrant in Middlesex Co., Ont. A single male was noted in
