 American Eared Grebe. 



Adult male : — Long ear tufts of rich, yellowish-brown ; head and neck all 

 round, black ; upper parts greyish-black; sides, chestnut; lower parts, silvery 

 grey; primaries, dark chestnut ; secondaries, white, dusky at the base ; length 

 13 inches. Young similar, the ear tufts wanting, and the colors generally duller. 



The eggs cannot be distinguished from those of the preceding species. 



Hab. Northern and Western North America, from the Mississippi 

 valley westward. 



I mention this as an Ontario species on the authority of 

 Dr. Garnier of Lucknow, Bruce Co., who informs me that a 

 specimen was sent to him in the flesh from Colpoys Bay, as 

 being something different from those usually seen at that point; 

 it was too far gone for preservation when received, but the Dr., 

 who has long been an ardent collector, assures me that he is quite 

 satisfied of the correctness of his identification. 



This species is comparatively a new acquaintance to 

 American Ornithologists, for although described by Audubon, it 

 was not found by him. It is now known to breed in Texas, Kan- 

 sas, Illinois, Dakota and Colorado, so that we need not be sur- 

 prised if a stragglerjs now and then wafted this far out of its or- 

 dinary course.
