This is from a few days back - but I think it deserves a second look. I hope thats OK.
Anna's is certianly the most common resident hummer here - but several key marks don't add up: the amount of rufous in the tail of this bird is no way an Anna's; the white collar this bird shows is not present to this extent on an Anna's; and the wings do not appear to be as long or longer than the tail.
Also, while the forehead looks as if the feathers could appear red in the correct light, they do not extend fully up the crown and down the back of the head to the nape - as an Anna's would - and theres no flare to the gorgets.
I think the bird is most certainly some flavor of Selasphorus. My reaction to the first picture is Broad-tailed. My reaction to the second photo is that the posture looks very much like a Broad-tail, but the rufous seems excessive. Perhaps a Broad-tailxRufous hybrid? Rufous would be the most common summer hummer here.
