DIVING BIRDS—Order Pygopodes. 
GREBES—Family Colymbidse. 
WESTERN GREBE. 
1. JEclimopliorus occidentalis. 25 to 29 inches. 
This is the largest of the grebe family. In summer the back 
of the neck is black, but in winter it is gray like the back. 
Nest. —A floating mass of decayed rushes, sometimes attached 
to the upright stalks; 2 to 5 pale bluish white eggs are laid, 
usually much nest stained (2.40 x 1.55). Breeding in colonies. 
Range. —Western North America, from the Dakotas and 
Manitoba to the Pacific, and north to southern Alaska. 
HOLBOELL GREBE. 
2. Colymbus Holboelli. 19 inches. 
This is next to the Western Grebe in size, both being larger 
than any of the others. In summer, they are very handsomely 
marked, as shown in the illustration, but in winter have the 
usual dress of gray and white. 
Nest. —Similar to above, the eggs averaging smaller (2.35 x 
1.25). 
Range. —North America, breeding from northwestern Alaska, 
in the interior of Canada and North Dakota. Winters usually 
on the coasts.
