BIRDS OF NORTHERN CANADA 415 



species as a migrant on the Mackenzie and up to 68° north 

 latitude. 



The Dominion Museum at Ottawa contains but six speci- 

 mens, including one taken there by Professor Macoun, and 

 one set of five eggs found at ISTachvak, Labrador, by Mr. R. 

 Guay, in June, 189Y! 



607. Louisiana Tanagee — Piranga ludoviciana (Wilson). 



This species has been met with at Fort McMurray, on 

 the Athabasca River, from Lesser Slave River to the Peace, 

 and in British Columbia. It does not appear in Mr. Ross's 

 List of Mackenzie River Birds. Mr. G. F. Dippie and Mr. 

 ^V. Raine have both received eggs and skins of this bird 

 from Red Deer, Alberta. On June 3rd, 1898, Mr. Wenmau 

 found a nest on the Red Deer River. It contained four eggs, 

 and was built in a poplar, five feet from the ground. Its 

 eggs resemble those of the scarlet tanager, and they are of a 

 dull greenish blue spotted with lilac and brown. 



There are no eggs, but twenty-seven specimen skins, in 

 the Ottawa Museum ! 



612. Cliff Swallow — Petrochelidon lunifrons (Say). 



On 15th June, 1889, Mr. Alexander C. Murray, of Fort 

 St. James, discovered a nest containing four eggs built 

 against the side of a beam or rafter of the post barn. Both 

 parents were seen and the female was shot. Contents of 

 eggs perfectly fresh. They annually breed, in fairly large 

 numbers, in suitable localities along river and lake banks in 

 New Caledonia, Northern British Columbia. In 1856 about 

 one hundred and fifty nests of this species were for the first 

 time built imder the eaves of the three principal buildings 

 of Fort Good Hope, Mackenzie River; but as many of the 

 young were destroyed by Indian boys, only one hundred 

 nests were constructed at the same place the following season. 

 In 1866 a cliff swallow was observed closely examining the
