Rushing Grebes
Western Grebes, San Luis Obispo County, California. This is mating behavior among Western and Clark's Grebes. I've read that the "rushing" grebes could be both males, competing for a female or a male and female, solidifying the pair bond. And they are the largest vertebrates able to "walk" on water, because they can take 14-20 steps per second, compared to 5-6 for a fast human. It's a kick to watch.
