THE BIRDS OF WISCONSIN. 
ORDER PYGOPODES: DIVING BIRDS. 
FAHILY PODICIPID^E: GREBES. 
^chmophorus occidentalis (Lawr.). WESTERN GREBE. 
One specimen in the collection of L. Kumlien, killed with 
a pitchfork, from a bunch of six in an air-hole in the ice on 
Lake Koshkonong, January 4, 1878. Another specimen form- 
erly in the collection of Thure Kumlien, now mounted and in 
the collection of the Oshkosh Normal School, was taken on 
Lake Koshkonong, October, 1881, (1) by F. Kumlien. The 
former does not appear to have been sexed, the latter is a 
female. We are positive we have seen others, but they are very 
rare in Wisconsin. 
Colymbus liollxellii (Rcinh.J. HOLB(ELL'S GREBE. 
Holbcell's grebe is found sparingly in March and early 
April on most of the larger inland lakes and rivers, as well as on 
Lake Michigan, and again from September, but more often 
from October, until the ice forms. Where there is open water, 
both on Lake Michigan and in the interior, many remain all 
winter. There is some obscurity in regard to the larger grebes 
in Wisconsin, and this without perpetuating the error of retain- 
ing crista t us. We are obliged to discard some of the early 
day records for the reason that the nomenclature has been so 
muddled that it cannot, with certainty, be unravelled. We 
have seen a young grebe, less than half grown, taken near the 
City of Green Bay, which is in all probability this species. 
There is no doubt that some large grebe nests, or did nest, 
rarely in Northern Wisconsin, and it seems not at all unlikely 
that it is holbwllii. 
C olymbus nuritus Linn. HORNED GREBE. 
Still fairly common as a spring and autumn migrant. Not 
infrequently nests in the northern part of the state, as it 
1. Not 1891. as labeled.
