seen on land, l)ut this species and the Holboell grebe are sometimes found on 

 the ice when bays and ponds suddenly freeze in winter. They are sometimes 

 found on the snow far inland in an exhausted condition. Indeed it seems 

 quite impossible for a grebe to take flight either from land or water unless 

 a considerable level surface is before it over which to propel itself both by 

 wings and feet while rising.

Field marks. This bird has a more brownish cast than our other 

 grebes, but the best mark at all seasons is the shape of its bill, which is 

 short and thick- -more henlike. Li the breeding season the black throat 

 patch and 1 )and on the bill are distinctive, while in winter it lacks the .shining 

 white checks of the Horned grebe, which is our onh' grelie liable to be 

 C(.)nfuscd with the present species.

 Didapper, and Water-witch, is found throughout New York during the 

 breeding season, whenever it is undisturbed in its favorite haunts. I
