Clark's Grebe
Aechmophorus clarkii
Description
First described in 1858, the Clark's Grebe was once considered a special color phase of the Western Grebe. Eventually the two birds were separated into distinct species because they nest side by side with very little interbreeding. Like the Western Grebe, the Clark's is known for its elaborate courtship display, which includes rapidly running across the waters surface. Another fun thing to see is a down-covered youngling riding on the back of its parent.
The Clark's Grebe primarily feeds by diving for fish. It also occasionally eats mollusks, crabs, and salamanders.
