1908.] BIRDS. 251 



Two specimens taken by J. Alden Loring at Henry House, Alberta, 

 early in October, 1895, have been recorded by Miller." 



Lasiurus cinereus (Beauvois). Hoary Bat. 



Alfred E. Preble and Merritt Cary obtained a fine female of this 

 large species on the Athabaska near the mouth of La Biche River. 

 August 29, 1903. It was caught among shrubbery on the river bank. 

 The species is evidently rare here, since none of the boatmen seemed 

 to be acquainted with it. 



Miller has recorded a specimen taken near Red Deer, Alberta.'' 

 Richardson described a specimen taken at Cumberland House.' 

 Though its size serves to distinguish this species from all other 

 northern bats, it seems to have been seldom recorded and is probably 

 rather rare, though doubtless of regular occurrence in 'Alberta and 

 southern Mackenzie. 



BIRDS OF THE ATHABASKA-MACKENZIE REGION. 



The following list is believed to include all species of birds that 

 have been authoritatively recorded from the region treated in the 

 present report. In the account of each species our own observations 

 are usually given first, in chronological order, the published records 

 following. Of the published references relating to the various 

 species only those have been utilized which best represent the dis- 

 tribution, dates of migration, breeding, and other interesting features 

 of their life history, preference usually being given to the notes 

 earliest published. Notes not accompanied by reference to the place 

 of publication are derived from manuscript records or verbal com- 

 munications.' 7 



Colymbus liolbcelli (Reinh.). Holbcell Grebe. 



This handsome grebe is a fairly common breeder in suitable places 

 throughout the wooded parts of the region. In 1903 a single in- 

 dividual was seen on Lily Lake, Alberta, May 13, and several at 

 Two Lakes, May 14. The species was next noted in the marshes 

 near Rocher River, June 6 and 7, and a pair was seen on the lake 

 near Fort Resolution, Mackenzie, June '20. Alfred E. Preble and 

 Merritt Cary noted it daily at I lay River, June 27 to July 1, and at 

 Fort Providence, July 1. On their return trip they saw one on the
