Oporornis agilis (WILS.) BAIRD. 1858. 
Mr. J. H. Fleming writes me that he once saw a Connecticut 
warbler at Ottawa. (Rev. G. Exfrig.) A rare migrant at London, 
Ont. (W. E. Saunders.) A regular spring and autumn visitor to 
this district, reaching us about 2oth May and leaving for the north 
a few days later, 30th May being the latest date on which I had 
noted it; as this bird is with us again before the end of August it is 
not unreasonable to hope that it will be found nesting at no great 
distance. While here the bird is very shy and keeps as much as 
possible to dense under-growths of vines, but when driven to the 
trees it tries to conceal itself by sitting motionless behind a limb; 
a curious habit of this bird is to walk slowly along the small branches 
of a tree peering into every crevice for insects, much after the man 
ner Seturus aurocapilus. Its song, which I have only heard on 
two occasions, has considerable merit, and it has also another note 
not at all unlike the well-known ‘‘teacher’’ of the oven-bird. I 
saw one or more of these birds daily from 22nd to 30th May, 1900; 
in the fall they are here during August and may be seen creeping 
cautiously through borders of Convolvult and Nasturtiums; on 18th 
May, 1896, I took a specimen in Jackson park, Peterboro’, Ont. 
(J. Hughes-Samuel.) 
A somewhat common summer resident of tamarac swamps in 
Manitoba; on June 21st, 1883, in the Carberry swamp found a nest 
and eggs of this species. For full description of this nest and eggs 
see The Auk for April, 1884, p. 192. On June 14th, 1884, at Duck 
mountain, found one or two pairs breeding in the tamarac swamp 
near there. (EF. T. Seton.) <A tolerably common summer resident 
at Aweme, Manitoba, arriving about the middle of May and leaving 
about Sept, 7th. (Criddle.) Regular but not very common in 
migration in Manitoba, breeds in some numbers in tamarac swamps 
in the northern portion of the province. Noted breeding in 1906 at 
Battle river, Alta. (Atkinson.) The writer paid a visit to the 
swamp south of Carberry in June, 1896, and had the good fortune 
to secure a nest on the outskirts of the bog and almost on a level
