646. Obange-oeowned Waeblee — Helminthophila celata 



(Say). 



Common in Northern British Columbia, Alaska, and 

 in the country to the south of the Peace River. Somewhat 

 rare in the Mackenzie River, region. It is also by far the 

 least abundant of the several warblers which annually breed 

 in the valley of the Anderson. We managed to secure a 

 few nests there over forty years ago. They held from four 

 to six eggs each, and they were made of hay or grasses lined 

 with deer hair, feathers and finer grasses, and were usually 

 placed in a shallow cavity on the ground in the shade of a 

 clump of dwarf willow or Labrador tea. 



The Ottawa Museum has four specimens, but no eggs, in 

 its National Collection, and these were obtained from Mr. 

 W. Spreadborough, who got them at Indian Head and Medi- 

 cine Hat in the years 1892 and 1894. 



647. Tennessee Waeblee — Helminthophila peregrina 

 (Wilson). 



On the 18th of May, 1885, an individual of this species 

 was shot near Fort Providence, Mackenzie River, and it was 

 later forwarded to Dr. Bell. An example was also shot at 

 Cumberland House, spring 1890, of which Major Bendire 

 only acknowledged its receipt at Washington in May, 1893. 

 T omitted to recount under No. 646, " that on June 18th, 

 1900, Mr. C. E. Whittaker found a nest of this rare warbler 

 at Peel's River, within the Arctic Circle. It was built in 

 the grass on the ground and contained six eggs. On June 

 22nd, 1902, Mr. Dippie found a nest and five eggs at Banfl^, 

 Rocky Mountains." The nest of the Tennessee warbler is 

 always on the ground, sometimes at the foot of a bush or 

 growing twig. They are generally arched over by the fine 

 dry grass of the preceding year. The nest is small and 

 loosely constructed, being quite flat; it is outwardly made, 

 of a few leaves, a little moss, and a good deal of fine grass, 

 lined only with the latter material. The eggs and their
