More Rufous Hummingbirds

Today, another attempt at capturing the Rufous Hummingbird frequenting our feeder. This time, I did not use the flash as there was a bit of natural light and this guy is easily startled. These hummingbirds look like they have fur on their back rather than feathers. I think it is more than just the color that gives me this impression.
