It only takes two to create a royal mob, at least when the mob consists of a pair of Western Kingbirds. This was the sight I enjoyed while strolling in a local park near our cabin in the Sierra foothills a week ago. Since spotting a Kingbird during a road trip through the Sacramento Valley last month, I keep seeing them in the valley and the foothills. They are fascinating.
After admiring this flycatcher near the edge of a large grassy area, I discovered the pair dive bombing a raven perched in the top of a sprawling oak tree. They took turns swooping around the larger bird, flaring their crimson crowns and perching nearby. Eventually the raven left, no doubt bored with their antics.

I like your bird photos. I didn’t know that two western kingbirds make a royal mob. (I also didn’t know what a western kingbird was, but I do now.)

I suppose that two birds does not a mob make, but they were “mobbing,” or harassing a larger bird, most likely to defend their nest area, so I took the liberty!
