Nikon D-7000 and Hummingbird
If you interesting in more photos
Very very impressive. You know what I find most impressive? You shot that without flash. Most hummingbird-in-flight shots I've seen used a flash, which changes the look of the bird. You can tell these shots because they have a bright dot in the eye, from the flash.
Personally, I think the birds look better with "natural" light, but it's a much harder challenge. To slow/stop the wings requires a fast aperture, which yields a thin DoF. A thin DoF makes getting focus on a bird that might ben in front of your lens for only a second or so rather tricky. Very fast apertures (like an 85mm F/1.4) can stop wings with natural light, but end up looking a bit soft at F/1.4.
So I'm very impressed with your shot, moreso than most hummingbird shots I've seen on this site.
Here are two of my hummingbird-in-flight shots I've taken with natural (no-flash) light, but neither of them are as good as yours, IMO:
