Hummingbirds are a diverse family of 320 species and they can mostly be found throughout the Americas. The smallest of all is the tiny bee hummingbird, Mellisuga helenae, weighing less than 2.5grams. They are among the world’s smallest bird species measuring 3 to 5 inches. Their English name derives from the characteristic hum made by their rapid wing beats which flap at high frequencies audible to humans. They can fly at speeds exceeding 15 meters/second (54 km/h; 34 mph) and they can also fly backwards, and are the only group of birds able to do so. This stunning coin has been produced in Green Titanium to mimic the coloring of the Green-throated Carib, which is one of the hummingbird species that can be commonly found in the British Virgin Islands. Due to the difficulty of striking Titanium coins and the fact that Titanium reacts differently with every strike, each seahorse coin is technically different from all others. There is also a lined effect that is present on the coins which is unique to this metal.
