That looks like a Calliope (sp?) hummer. Smallest of all the hummers, easy to spot because the male's throat is broken lines of red versus a solid red like a ruby throated or broadtailed.
I've heard a hummer twice now in my vicinity in the past week, I have 2 feeders, but nothing spotted yet (then again, I'm not home most of the day, either). Last year, I did have a little girl who would take a sip from my hyssops on a regular basis (the hummer feeder wasn't working like they like it.. or had too many mud wasps on it).
My mom, who's living right now in the southern NM mountains used to put out 7 feeders that would be attached to 2-liter bottles (big coke bottles) and we would have to fill them up twice a day. I figured that there would be between 75-200 hummers at any given point (yes, seventy-five to two-HUNDRED). They would wipe out those bottles within 2 hours of me filling them up (this is when I was a teenager). Each feeder had 8 feeding points and, as I'm tilting the bottle from upside down to right-side-up, I would have hummers landing on my fingers drinking and there would be a line waiting. I'd usually get covered in hummer poo (red liquid) pretty quick. We had Broadtails, ruby throated, calliopes, and rufus. Loved the rufus hummers.. so striking in their hot orange feathers! Never ever saw a violet hummer, much to my dismay.
Mom's got video somewhere (using our giant old Curtis Mathus VHS camcorder) of the HMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMM sound and watching them all flit here, there, & everywhere. Perhaps I can get her to find it so I can get that vid digitized.. that would be so cool.
