Selasphorus platycercus
We see three types of hummingbirds here -- Broad-tailed, Black-chinned, and Rufous. Very occasionally a few people see migrating Calliope Hummingbirds. All of them have left now, except a few stragglers, such as this female, which I think is a Broad-tailed Hummingbird. I don't think this is one of the birds that spent the summer here -- this one seemed confused by the feeder, trying to get at the nectar through the bottom. She did figure it out, though, hopped on top and got a drink.
