426 THKOUaH THE MACKENZIE BASIN 



has it on his List, " North to Fort Simpson, but rather rare." 

 Common on the Saskatchewan Kiver. Scarce in British 

 Columbia^ The Dominion Museum collection at Ottawa 

 comprises eight specimens, two of which Professor Macoun 

 himself secured there in May of 1888, and two sets of eggs. 

 One of these was found at Gaspereaux, N.S., on 10th June, 

 1901, in a small spruce bush, four feet from the ground, com- 

 posed of fine twigs, grasses, etc., and lined with horse hair. 



660. Bat-beeasted Waebi,ee — Dendroica castanea Wilson. 



There can be no doubt that this warbler is at least spar- 

 ingly present in the Cumberland District every season for 

 the natural purpose of reproduction. Even at Pelican Nar- 

 rows Mr. McKay, early in June, 1891, procured a specimen 

 skin which was forwarded to, identified, and duly acknowl- 

 edged at Washington. It is not, however, abundant any- 

 where in Western Canada. Mr. E. A. Preble took a skin 

 at Oxford House, Keewatin, on July 3rd, 1901. There are 

 five specimens, but no eggs, in the Ottawa collection ! Two 

 of the specimens were obtained at Brandon, Manitoba, in 

 June, 1880, by Professor Macoun himself. 



661. Black-poxl Waeblee — Dendroica striata (Forster). 



Two fuU sets of the eggs, nests and skins of this species, 

 received from Fort Eae, were forwarded to Mr. Dalgleish 

 in the summer of 1881. On 16th May, 1885, Mr. Keid, of 

 Fort Providence, obtained an example skin, which was after- 

 wards sent to Dr. Bell. Early in June, 1891, Mr. McKay 

 took a nest with five eggs near Pelican Narrows. He states 

 that they nest on bushes and that they " whistle very pret- 

 tily." Mr. Koss remarks that they are common on the 

 Mackenzie River north to La Pierre's House, while we found 

 them more plentiful than D. coronata at Fort Anderson, 

 where twenty-one nests were collected upwards of forty years 

 ago. They were similarly made and situated, and contained 

 four and five eggs each. The eggs are generally blotched
