The Amethyst Woodstar is found in South America east of the Andes from Venezuela to northern Argentina. It is one of the smallest hummingbirds. The Amethyst Woodstar's scientific name is Calliphlox amethystina. The Amethyst Woodstar is very small and with short wings and is one of the most proficient fliers in the hummingbird world. Its wing beats have been measured at 80 per second for the male and 70 per second for the (slightly larger) female giving her a slightly lower humming note. Its heart beat has also been measured at 20 beats per second or 1,200 beats per minute!
