Humming or humming bird is part of the Trochilidae family. A large family with over 400 species distributed only in the Americas from Alaska to Tierra del Fuego, on the sea shore by high mountains covered with snow. But most species live in tropical regions of South America. Due to their specific food which consists mainly of nectar, their flight is more akin to that of moths feeding. High frequency of wing beats (8-12 beats per second for larger bird species, 20 to 25 for the medium and up to 100 for the smallest) makes the crow flies to vibrate, and the bird can move with a high speed and at the same time be able to suddenly change direction of flight, or to stand still like a helicopter.
