Hummingbirds name comes from the fact that they flap their wings so fast (about 80 times per second) that they make a humming noise. Hummingbirds can fly right, left, up, down, backwards, and even upside down. 🙂
I took these photos with Canon 135 mm lens, then cropped a lot to get a close look of the bird, so the quality is not great. Wish I had my 300 mm lens with me.
