SOME ADDITIONS TO A LIST OF THE WINTER 

 BIRDS OF SOUTHEASTERN MICHIGAN. 



Part III. 



p.. H. SWALES. 



In the Wilson Bulletin No. 42, March, 1903, p. 20-24, and 

 No. 48, Sept. 1904, p. 82-83, I published a list of seventy-one 

 species that I have been able to record as occurring in South- 

 eastern Michigan during the winter months of December, 

 January and February. Since 1904 I am now able to add 

 eighteen species, making a total of eighty-nine species found 

 during the winter months. It is needless to state that I do 

 not deem these 89 species as being all winter birds, but it is 

 interesting merely as demonstrating to what extent the regu- 

 lar winter fauna can be> added to by stray migrants or sum- 

 mer residents that, for some reason or other, remain during 

 all or a portion of the winter. 

 No. 72. Lams Philadelphia. 



Bonaparte's Gulls were found to linger decidedly late in 

 1911. In the early part of December small straggling flocks 

 could be seen almost daily working down the river, pausing 

 to feed on the open river, here and there. I failed to detect 

 them after December 15, when a flock of fifteen passed down, 

 but others probably remained later as the river remained prac- 

 tically free from ice until December 28. 

 No. 73. Phalacrocorax aiiritus auritus. 



The latter part of December, 1907, and early January, 1908, 

 were rather mild, the temperature being as high as 53° on 

 December 27. The river was entirely free from ice and the 

 ground was devoid of snow. On January 8, 1908, I saw a 

 Double-crested Cormorant swimming on the river directly 

 in front of my place on Grosse Isle. I was able to approach 

 within fair range before it saw me ; it rose heavily, with la- 

 bored flapping, and flew down towards Lake Erie. 

 No. 74. Branta canadensis canadensis. 



Canada Geese frequently remain all or during that portion 

 of the winter when the lake remains either open or with little
