BRITISH COLUMBIA SUPPLEMENT. 



WITH ANNOTATIONS BY ALLAN BROOKS, 



Fauiially speaking, the situation in the southwestern part of British Cokniibia is practi- 

 cally identical with that in northwestern Washington. A bird occurring upon either side of 

 the line is almost sure to he found upon the other, and it is as impossible, as unnecessary, to 

 draw distinctions between these regions. .AH that has been said in the foregoing pages, there- 

 fore, of bird-life in western Washington is equally applicable to the Fraser delta country and 

 to the eastern end of Vancouver island. So far as the environs of our two chief cities are 

 concerned we should need no "British Columbia Supplement." A strong similarity exists 

 also betw-een the fauna of eastern Washington and our own "dry belt." insomuch that we 

 have recently added to our British Columbia list, chiefly through the commendable activities 

 of Mr. Chas. de Blois Green, some of the most characteristic species of the -\rid Transition 

 zone, such as Williamson's Sapsucker. the White-throated Swift, the Canyon Wren and the 

 Sage Thrasher, formerly supposed not to range north of the Forty-ninth Parallel. But our 

 mountainous hinterland does afford characteristic differences: and these, while still remote 

 from most of us in experience, are nevertheless of interest to us as residents of British 

 Columbia. The northern portion of the Province begins to assume a sub-arctic faunal com- 

 ple.xion. especially in winter; while the ornis of our eastern mountain system not only has 

 specialized forms of its own but is tinged strongly by the residue of those tidal waves of 

 migration which, sweeping across the central prairies in a northwesterly direction, break 

 upon the eastern slopes of the Rockies and spill over into the quieter valleys of the interior. 

 A brief account of these peculiar birds is added, with the assurance that thereby we are 

 formally completing the list of British Columbia birds, and that we shall be able to obtain 

 within the pages of this work information relative to all the birds known to occur in our 

 Province.
