48 TYRANNID^E I FLYCATCHERS. 



later Mr. Osborne discovered another nest in Oxford 

 County, Me., in a similar situation, with four eggs well 

 advanced in incubation on the i8th of June. "The nest 

 was built in the side of a hummock of moss, under the 

 roots of a small tree, and was only about half covered 

 over, the eggs being clearly visible from the outside." 

 The eggs were also spotted. (Bull. Nutt. Club, iv., Oct. 

 1879, P- 240.) 



To place this matter of the lowly nesting and spotted 

 eggs of the Yellow-bellied Flycatcher, by which it differs 

 somewhat from all its eastern congeners, beyond all 

 doubt for the future, I will sum the observations of a 

 third independent observer who himself took two nests, 

 making five in all here described. Mr. C. F. Batchelder's 

 first nest was taken June I4th, 1879, at F rt Fairfield, 

 Me., in wet mixed woods. It was placed on the edge 

 of a bank formed by a decayed tree trunk, over a pool, 

 protected from view by some green moss growing upon 

 a projecting root, and partly sunken in the surrounding 

 moss. The materials were fine brown roots, bits of 

 rotten wood, the scaly coverings of buds, apparently of 

 the arbor vitae, together with a few sticks and withered 

 leaves, and one or two bits of arbor vitae and green 

 moss ; with fine black rootlets and withered grasses for 

 lining. The outer diameter was four inches, the inner 

 two and three eighths, with an outer depth of two and a 

 quarter, and cavity one and a quarter deep. The four 

 eggs were white, with a slight creamy tinge, spotted and 

 blotched with two shades of light reddish-brown, mostly 

 about the larger end ; two of the eggs also having a few 

 fine dashes and specks of black over the other markings. 

 These four measured 0.68X0.52; 0.68x0.52; o.66x 

 0.51; 0.66x0.51. The other nest, found June 27,
