28 BIRDS'-NESTING. 



of the latter, E, trailli, is entirely unlike any nest of 

 this species from the Canadian Fauna." Nests in Mr. 

 H. B. Bailey's collection from Dakota are like those 

 of the olive-sided flycatcher, built of rootlets near 

 the ground ; while, to crown the diversity, Pearsall 

 found a nest of this species near Bay side, L. I., 

 June 24, which was suspended in a horizontal fork 

 and made of scanty fibrous grasses, like the nest of 

 the E, acadicus in all particulars. 



In the far west we find that an equal diversity 

 obtains. Ridgway, for example, took two nests in 

 Parley's Park, Utah, one of which was loose and 

 partly pensile, the other compact and supported in 

 the crotch of a brier-bush. Finally there remains to 

 be mentioned, as occurring on the middle line between 

 the species and the variety, a remarkable home of 

 this flycatcher met with, on June 28, by Mr. Ludwig 

 Kumlien, in Jefferson county, Wisconsin, of which 

 Dr. Brewer gives particulars. This nest was placed 

 in a thick mass of coarse marsh grasses, near the 

 ground, on the edge of Lake Koshkonong, and was 

 firmly interwoven with the tops of the surrounding 

 herbage. The grass and reeds, among which it was 

 made, grew in the midst of water, and it was discov- 

 ered by accident in a hunt for rails' eggs. "It is a 

 large nest for the bird ; its base and sides are made 

 of masses of soft lichens and mosses, and within this
