Parker, Jr., obtained one specimen on April i, 1890, from a flock 

 of six at Grand Crossing. My own observations are as follows: 

 Took one specimen of two, observed on Lake Calumet May 28, 

 1889, and one at Worth, Illinois, on September 18, 1889. 



The above observations would appear to indicate that the 

 Horned Grebe, which is exceedingly tame during its migrations, 

 is very shy and retiring during the nesting period, as no breeding 

 notes have been obtained since 1878 for this area. I also find 

 that this species has been reported a great many times. Its range 

 covers the northern hemisphere, and in North America it breeds 

 in the northern United States and northward.

While the American Eared Grebe has been reported several 

 times as occurring within our limits, I have not been able to 

 find a single record of an authentic specimen of this species 

 having been taken. The only published record is that of Mr. 

 E. W. Nelson, who says*: "Not uncommon in winter upon 

 Lake Michigan. Several species of grebes and a number of 

 ducks are occasionally taken during the winter upon the hooks, 

 set several miles off shore by the fishermen." 



The range of this grebe includes northern and western North 

 America' from the Mississippi Valley westward.
