The Canadian Warbler is a migrant through southern New England and the lower Hudson Valley in the second half of May and in September. As a migrant it is found chiefly in wet woodland, where it keeps rather low in the bushes, though it may occur in dry places, and when singing often mounts fairly high in trees. It breeds from the edge of the Canadian Zone northward, occurring here and there in deep, cool swamps, even in central and eastern Massachusetts, and not uncommonly in the highlands of western Massachusetts. It is often abundant in the thickets of mountain maple on illdrained mountain summits. It is very inquisitive, and an intruder may frequently hear its alarm-note, chick, or catch a glimpse of the black “necklace” across its yellow breast as it flies low in the bushes. Its song is a rather hurried outpouring of notes, introduced by the same chick which it uses as an alarm-note. (See Magnolia Warbler.)
