678. Connecticut Warbler. 



Oporoniis agilis (Wils.) Baird. 1858. 



Mr. J. H. Fleming writes me that he once saw a Connecticut 

 warbler at Ottawa. {Rev. G. Eifrig.) A rare migrant at London, 

 Ont. {W. E. Saunders.) A regular spring and autumn visitor to 

 this district, reaching us about 20th 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 Seiurus aurocapillus. 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 Convolvidi and Nasturtiums; on i8th 

 May, 1896, I took a specimen in Jackson park, Peterboro', Ont.

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. (E. 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
