rather open bog forest. Conifers probably form the chief influence 

 in determining the resorts of this bird, which follows the hemlock, 

 spruces and balsam well up on the mountainsides. Benjamin Hoag 

 ('94, p. 87) describes the nesting of the Magnolia Warbler at 

 Stephentown, New York, as follows : " They had chosen for their 

 summer home a woodland corner on the higher ground above a 

 timbered swamp. Here in past years some of the timber had been 

 cut, leaving little clearings among the tall pines, hemlocks, and 

 deciduous trees, . . . and just across an old wood-road from, one 

 of these bush-grown clearings the nest was located. It was about 

 six feet from the ground, on one of the lower limbs of a hemlock 

 sapling, and was loosely constructed of fine hemlock twigs, weed- 

 stems, and a few scraps of yellow-birch and wild-grape barks ; lined 

 with fine rootlets and horsehair." 



Myrtle Warbler; Yellow-rumped Warbler. Dendroica cor- 



onata (Linn.) 



Length 5.6. Upper parts mottled blue-gray ; crown-patch and rump 

 yellow; throat, wing-bars, tail-spots and bell}" white; breast black at the 

 sides, heavily spotted below. 



Sphagnum-carpeted localities, with scattered clumps of young 

 spruces and firs and occasional deciduous trees, making the area 

 about half open, are most favored by the Myrtle Warbler. It 

 obtains its food mainly from spruces and fir, and nests in their lower 

 branches, laying grayish white eggs spotted with brown. I did not 

 find this warbler so plentiful at Cranberry Lake as is the Chestnut- 

 sided, but the prevalence of clearings made the latter more notice- 

 able than the former, as the Myrtle Warbler has little to do with 

 clearings except where they meet the woods. 



Black-throated Blue Warbler. Dendroica cccndescens cccru- 



lescens (Gmel.) 



Length 5.2. Upper parts grayish blue; white wing patch; sides of 

 head, throat, sides of breast and belly, black ; otherwise, white below. 



This Warbler prefers the typical mixed woodland in its dry open 

 aspect. The preferences of this warbler in its Canadian summer 

 home are described by Kells ('87, p. 76) : " The favorite habitat of 

 the Black-throated Blue Warbler is high, hardwood, timbered lands, 

 where there is a thick growth of low underbrush, and while the 

 males seek an elevated position among the leafy boughs for the dis- 

 play of their musical talents, the females usually select a lowly site 

 for the cradle of their progeny." This characterization applies to 

 the bird's habits here, as I encountered it in the Partial Clearing, 

 and also in the dry open woods across Sucker Brook. Egbert Bagg 

 ('87, p. 90) gives an interesting account of this warbler's habits 

 near Holland Patent, in Oneida County. He describes the locality 

 as high and -dry ground, nearly, if not quite, surrounded by a 

 swamp. " On this knoll, which was covered with large timber 

 standing rather openly, but grown up thickly with brush from three 

 to ten feet high, on the driest part where the brush was lowest, and
