I snapped this(slightly blurry)female Ruby-throated Hummingbird in flight as she hovered near the feeder. The white tips on the tail feathers distinguishes this bird as a female, she is slightly larger than the male too. You will often hear the characteristic buzzing sound of a hummer before you see it. The Ruby-throated ones have an average wingbeat of 52 beats per second. They can fly at 30 mph and dive at up to 63 mph! To be so little, they sure are fast!
