(Downs.) Uncommon summer resident in Nova Scotia. (H. F. 
Tufts.) Seen in woods at Margaree, Cape Breton island, July, 1898. 
(Macoun.) One seen on Sable island, Oct. 7, 1905, and another 
Sept. 28, 1907. (J. Boutelier.) A few were detected at Souris,

I have seen them from May 4th to October 5th. (Wzntle.) 
A moderately common migrant in the vicinity of Ottawa. (Ottawa

and fall in the county of Leeds, Ont. Once I found the nest in 
June, 1899, in an ash swamp. It was built in a bush of Sprrea that 
grew among ferns and weeds, and was not more than three feet 
from the ground. The bird was very tame and easily identified. 
The nest much resembles the nest of the redstart except for location. 
I have also noticed this bird near Sharbot Lake, Ont., where it breeds 
in the underbrush of a large wood of maple and beech. Near Madoc 
I have noticed it among the latest warblers to depart south. (Kev. 
C. J. Young.) Regular migrant at Toronto, Ont. An abundant 
summer resident in the Parry Sound and Muskoka districts of 
Ontario. I took a nest on June 8th, 1894; it was on the side of a 
hill in a dense hardwood bush, and was placed on the fallen branch 
of a dead hemlock, shaded by the horizontal branch of a seedling 
maple. (/.H. Fleming.) Common amongst balsam fir in Algonquin 
park, Ont., June, 1900. (Spreadborough.) Reaching us in the first 
week in May at Toronto this bird becomes very abundant. The
