formerly did even in the southern tier of counties. Young a 
few days old were procured at Lake Koshkonong during June, 
1880. Few of our birds have suffered more from the 
depredations of the plume hunter, than has this species. 
Colymbus nigrieollis calif oriiicus (Heerm.). AMERICAN EARED 
GREBE. 
Very rare in Wisconsin. We have received two spring 
specimens from near Iron River, Bayfield County, but have 
never personally come upon or taken one in Wisconsin. Mr. 
H. A. Winkenwerder. of Watertown, Wis., has sent us a wing 
of this species, which is said to have come from a bird shot at 
that place. We suspect the bird to be a rather rare migrant 
in the western part of the state, and possibly to breed in small 
numbers in the extreme northwestern portion. Mr. E. W. 
Nelson, in 1876, says of this species (1): "Not uncommon in 
winter upon Lake Michigan." This is certainly good authority, 
but entirely contrary to our observation. 
Podilyinlms podiceps (Linn.). PIED-BILLED GREBE. 
A common summer resident in all suitable localities. It 
arrives in southern Wisconsin early in April, if an average 
season, and remains until the ice forms, usually in Xovember. 
Apparently has not decreased in numbers during the past forty 
years. 
FAniLY GAVIID/E: LOONS. 
Gavia im1>er (Giant.). LOO\. 
This loon may be found on Wisconsin waters almost anv 
month of the year, and during March and April is a common 
migrant on all inland lakes and streams. In autumn it is less 
common inland, but occurs plentifully on Lake Michigan and 
the Mississippi River. A number remain all w inter on Lake 
Michigan. It was formerly a common breeder on the small 
lakes from the southern tier of counties northward. Thirty 
years ago it bred on Lake Koshkonong and many other small 
lakes where it now occurs only during the migrations. A few 
nested at Delavan lake up to 1888. and possibly a straggling 
pair now and then for a few years later. Farther north, where 
the country is less thickly settled, many still breed. Extremely 
variable in size, there being a range of variation of from six to 
1. "Birds of Northeastern Illinois"; Bulletin of the Essex Institute
