HORNED GREBE. 
3. Colymbus auritus. 14 inches. 
In winter this Grebe is one of the plainest in its dress of gray 
and white, but summer brings a great change, making it one of 
the most attractive, with its black, puffy head, and buffy white 
ear tufts, the front of the neck a rich chestnut color. Their 
food consists almost wholly of small fish. 
Nest. —Is a loosely built mass of vegetation floating in the 
bog and water holes of the western prairies. The eggs, 3 to 7 
in number, are brownish yellow (1.70x1.15). 
Range. —Breeds from Dakota and Illinois northward; win¬ 
ters to the Gulf of Mexico. 
EARED GREBE. 
4. Colymbus nigricollis californicus. 13 inches. 
This species is rarely found as far east as the Mississippi 
River. In summer the neck is black, lacking the chestnut color 
of the former. It can always be distinguished from the Horned 
by the upper mandible being straight on the top. 
Nest. —In colonies similar to the above, laying from 3 to 8 
eggs, which are usually nest stained to a brownish cream color. 
Range. —From the Mississippi to the Pacific, nesting from 
Texas to British Columbia.
