"Connecticut Warbler" is an unfortunate misnomer for this species. 

 'Swamp' or 'Tamarack Warbler,' or 'Bog Black-throat,' would have 

 been much more truly descriptive. 



IN the cold, boggy tamarack swamps of Manitoba, where I found it 

 breeding, it was the only one of the family, and almost the only bird, 

 whose voice broke the silence of those gray wastes. Its loud song was 

 much like the "teacher, teacher" chant of the Oven-bird, but it also 

 uttered another, which I can recall to mind by the aid of the syl- 

 ables "free-chappie, free-chappie, free-chappie, WHOIT." 



The nest was placed on the ground, or, rather, in the moss which 

 everywhere covered the ground to a depth of a foot or two, and was com- 

 posed of fine vegetable fibers. 



This species has somewhat the manners of the Vireos, but is much 

 more active and sprightly in its movements. During the migrations 

 it is generally found on or near the ground, in the undergrowth of low, 

 damp woods, and also in bordering, weedy fields, where it sometimes 

 announces its presence by a sharp peek. ERNEST THOMPSON SETON. 



679. Oporornis Philadelphia (Wils.]. MOURNING WARBLER. Ad. &.

 white eye-ring; rest of upperparts, wings, and tail olive-green; no wing-bars

 green, slightly grayer on the head; breast grayish, throat whiter. L., 5'63; 

 W., 2-56; T., 2'13; B. from N., '32. 



Remarks. This species bears a general resemblance to the preceding, 

 but may be distinguished from it by the absence of a white eye-ring.
