We have a few hummingbirds that hang around the back of the house year round, so I got them 2 feeders. A male Anna's became the dominant one and would chase everyone off the feeders. My wife yesterday commented that our bird is getting fat, so I went out on the deck this evening and took a picture of him and check. It is not red anymore, it is more like purple; did our Anna's change color or did it get chased away by a Costa's? San Francisco Peninsula, Northern California.
