I spent the last two mornings at Coyote Lake County Park east of Gilroy, CA with the goal of photographing Western Grebes (and/or their close cousins, Clark’s Grebes) engaging in their fascinating courtship behavior. The grebes did not disappoint as you can see in the following pictures. One post on the “South Bay Birds” mailing list described this viewing opportunity as one that occurs about once a decade, or perhaps only once a generation within Santa Clara County!

Two Western Grebes (Aechmophorus occidentalis) engage in a courtship ritual known as "rushing", where they race across the water in synchrony.
