One afternoon at Madera Canyon, after we’d shot for a few hours in the morning and eaten breakfast, I sat on the tiny deck off the back door of my cabin with my 600mm lens in my lap. The hummers were mostly taking a break and the feeders, which were just outside my cabin, were devoid of birds. I noticed movement in a bush on the edge of the canyon and saw this immature Anna’s Hummingbird perched deep in the leafy shrub. Earlier, we had watched as he took charge of the feeders and forced every bird off of the feeders one by one, then started over again as the other hummers, mostly Broad-billed Hummers, returned to feed. I’d never seen anything quite like it. The Anna’s I’m familiar with are quite territorial but this behavior was over the top. This feisty one took it upon himself to wreak general havoc. Later that afternoon, while I watched him in the shrub, a male Broad-billed discovered the Anna’s and spent a few minutes harassing him, jabbing at him with his beak. The Anna’s held his ground but he seemed a little uncomfortable afterward and kept an eye out when the Broad-billed flew off. After the Broad-billed encounter, the Anna’s investigated the feeders and eyed me with interest. And, although later, the Anna’s returned to the feeders while other birds were there, he was never quite as aggressive as that first time.
