E. FLAVIVENTRIS I YELLOW-BELLIED FLYCATCHER. 47 



fresh green mosses, thickest around the rim or parapet. 

 The home of the Bridge Pewee (Sayornis fuscus) was at 

 once suggested. But no mud entered into the actual 

 composition of the nest, though at first we thought so, 

 so much was clinging to it when removed. The lining 

 was mainly of fine black rootlets, with a few pine-needles 

 and grass-stems. The nest gives the following measure- 

 ments : depth inside one and a half inches ; depth outside 

 four and a quarter inches ; circumference, inside, seven and 

 a quarter inches. The eggs, four in number, were per- 

 fectly fresh, rounded oval in shape, and of a beautiful 

 rosy-white tint, well spotted with a light reddish shade 

 of brown." 



Mr. S. D. Osborne soon supplemented this excellent 

 account (ibid., p. 187): "On Monday, June 10, 1878, 

 while collecting in company with Mr. R. F. Pearsall, on 

 the island of Grand Menan, I flushed a Yellow-bellied 

 Flycatcher, which seemed to come from directly under 

 my feet. The locality was a good-sized hummock of 

 moss, in swampy ground at the edge of some low woods. 

 For some time I was unable to find any signs of a nest, 

 but finally I discovered a small hole one and a half inches 

 in diameter in the side of the hummock, and on enlarg- 

 ing this opening the nest, with four eggs, lay before me. 

 The bird, which had all the time been hopping around 

 within a few feet of our heads, was at once shot. The 

 cavity extended in about two inches, was about four 

 inches in depth, and was lined with a very few grasses, 

 black hair-like roots, and skins of berries. The eggs, 

 four in number, are white, with a very delicate creamy 

 tint, which differed in its intensity in different specimens, 

 and are spotted, mostly at the larger end, with a few 

 dots and blotches of a light reddish shade." About a year
