The only record that I have found of the occurrence of Hol- 

 bosll's Grebe within our limits is that of Mr, E. W. Nelson, who 

 says*: "Rather uncommon winter resident upon Lake Michi- 

 gan." Mr. Ridgway saysf that it is a winter visitant to Illinois. 

 This being the case it would naturally appear upon the lake 

 border of our district. 



The range of this grebe is North America in general, in- 

 cluding Greenland. It breeds from Minnesota and Maine north- 

 ward and migrates, in winter, southward quite through the 

 United States. It is also a native of eastern Siberia, southward 

 to Japan.

Mr. E. W. Nelson in his report on the Birds of Northeastern 

 Illinois, states that in 1876 this species occurred casually from the 

 first of October to the tenth of November and during April. 

 He also states that it bred sparingly on the small lakes of this 

 region. Mr. George L. Toppan has a specimen in the downy 

 plumage, taken May 24, 1878, at Sheffield, Indiana. Mr. J. G.
