of the waders and swimmers which frequent that region. The seasons 

 of 1907 and 1908 were spent by him on Vancouver Island. 



The chief sources from which pubhshed observations and notes 

 have been compiled are indicated in a brief and far from complete 

 bibliography. As regards Greenland and Alaska no attempt has 

 been made to utilize all that has been published. It has been 

 thought sufficient to refer to the most important lists and to include 

 all the"species known to occur in these regions. It cannot be hoped 

 that no important omissions have been made in the distribution of 

 Canadian birds, but as the authors expect to publish annually an 

 addendum to this catalogue the necessary corrections will be made 

 from time to time and the co-operation of collectors and observers 

 is solicited for this work. 



In addition to the list of authorities cited, manuscript lists and 

 notes on nesting habits have been furnished the writers by Mr. J. H. 

 Fleming, Toronto, Ont. ; Mr. W. E. Saunders, London, Ont. ; Mr. 

 Geo. White, Ottawa, Ont. ; Mr. E. T. Seton, Cos Cob, Conn. ; Mr. A. 

 C. Bent, Mr. Walter Raine, Toronto, Ont. ; Mr. J. Dippie, Calgary, 

 Alta. ; Mr. Robt. Elliott, Plover Mills, Ont. ; Mr. P. A. Taverner, 

 Bracebridge, Ont.; Mr. C. R. Harte, Nova Scotia; Mr. Harold Tufts, 

 Wolfville, N.S. ; Rev. C. J. Young, Madoc, Ont. ; Rev G. Eifrig, 

 Ottawa, Ont.; Mr. J. Hughes-Samuel, Toronto, Ont.; Mr. W. H. 

 Moore, Scotch Lake, N.B.; Mr. Alfred L. Garneau, Ottawa, Ont.; 

 Mr. A. B. Klugh, Guelph, Ont. ; Mr. A. F. Young, Penetanguisliene, 

 Ont.; Mr. Norman Criddle, Aweme, Man.; Mr. Geo. A. Atkinson, 

 Portage la Prairie, Man.; Mr. E. F. G. White formerly residing in 

 British Columbia, but now at Ottawa; many members of the Geolo- 

 gical Survey staff and others who have contributed notes or short lists. 



The whole series of the Transactions of the Natural History Society of 

 Nova Scotia; the Bulletin of the Natural History Society of New Bruns- 

 wick; the Canadian Naturalist and Record of Science, Montreal ; the 

 Ottawa Naturalist; 'the Journal of the Canadian Institute, Toronto; the 

 Auk, published in New York and the Wilson Bulletin have been drawn 

 on for notices of rare species and local lists by various contributors. 



The greater part of the compilation of the new material for this 

 edition of the Catalogue has been done by my assistant Mr. J. M. 

 Macoun. The very complete index was made by Miss Marie C. 

 Stewart.
