Rufous Hummingbird

I do try to limit myself to one bird blog post per day, but I couldn't help myself when this handsome little guy showed up at my feeder this morning and I was able to rattle off a few frames.  A few days ago I posted about a female Rufous which was much more difficult to identify than this male that screams out why it is called "rufous".  I post these three photos so you can see the gorget in three different shades of light.  Pretty dang awesome!!!

From my photography skills development perspective...I like the morning light that captured the eye gleam and illuminated the full length of the bill.  I like the feather detail I was able to get, even the texture on top of the head running down to the bill.  Can anyone tell me what shutter speed or other camera settings are best to capture the wings in freeze-frame rather than getting the wing-blur?

UPDATE:  A Rufous Hummer (possibly the same bird as this morning) was here this evening alternating between perching in the tree, pooping, and then coming to the feeder.  I was able to get a close-up with too much leaf shadow.  Still, the photo below shows another characteristic of the Rufous Hummingbird that I was not able to show with it in flight.  Check out the green patch basically at the armpit (or wingpit).  The wing itself is also mostly green in color and is well painted in The Sibley Field Guide.
