The Booted Racket-tail is simply a marvel of nature. It has a long tail, which is composed of bare rachises ending in a wide racket-like structure. At first glance, it can resembled the Long-tailed Sylph, but the tail’s shape is unmistakable once taken notice. Other than its most conspicuous trait, it has white feathers covering its legs, which explains why it is called Booted. The body is mostly green but iridescent like many hummingbirds, making it change in coloration with the view angle. The black bill is straight and short.
