We only really see the Anna’s and Rufous hummingbirds in this region.
Because of the very green back and lack of general rust-coloured areas, specifically the lack of red on the side of the torso its an Anna’s. Then because it is missing the (magnificent) head colouring it is a female.
If I am correct, that is a female Anna’s Hummingbird.
Merlin agrees. How do you tell she’s a she?

Oh I looked in this book and see what you mean. 👍👍
