576 HISTORY OF THE 



commonest species breeding at that place. Its favorite haunts, 

 in tlie midst of dense thickets, shelter it from the observation of 

 one not accustomed to its song, which, however, is one of the 

 most striking that reaches the ear of the traveler in that region; 

 but the songster, perched on some low branch, is quick to take 

 alarm, and skulks away beyond the sight of one penetrating its 

 haunts. 



"At Fort Yukon, Lockhart shot a bird from its nest on June 

 21st. This nest was concealed under a small pile of drift close 

 to the river bank, under a large willow tree. Another nest ta- 

 ken near by was similarly placed, and made of moss, lined with 

 very fine grass. In the National Museum Collection is a nest 

 containing five eggs, from Peale's River, which is composed of 

 moss and grass, and lined with mouse and rabbit fur. There are 

 also other eggs in the same collection, which were obtained from 

 Fort Yukon daring the middle of June." 



I am indebted to Capt. Chas. Bendire for the following di- 

 mensions of the set of eggs from Peale's River: .72x. 54, .72x 

 .54, .72X.54, .74x. 55, .78x. 56. He says that this set and other 

 eggs of this bird in the United States National Museum are not 

 distinguishable, in color or form, from the eggs of S. motacilla.
