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 × 1.25).
Range.—North America, breeding from northwestern Alaska, in the interior of Canada and North Dakota. Winters usually on the coasts.
