The Anna's hummingbird is a common sight in California. A male and a female live in our neighborhood, and I change the water in our feeder (4 parts water to 1 part sugar) every week or so. The males and the females are about the same size (.1-.2 oz), but the females are most likely the only ones you'll see in a nest. They can be easily distinguished by color. The males have a rose-pink crown and gorget, or throat, which are strongly iridescent. Females have metallic green plumage on their backs and only a tiny red gorget on their throats.
I've been watching our pair for several days. The female frequents the feeder much more than the male, but in photographs, it's no contest. Since it's been raining for the past couple of weeks getting a good image of the male with the iridescent color has been next to impossible.
The sun came out today. They were both hungry.
