Hummingbirds (Colibris) are the smallest birds in the world. They measure between 5 and 13 cm and they live exclusively on the American continent, most species preferring the tropical region of South America.
The fast pace of their wingbeats (up to 100 per second) makes their flying buzz with vibration, and it also enables them to cover distances very quickly, change direction suddenly or hover in a fixed spot up in the air, like a helicopter. They can also fly backwards, and are the only birds able to do so.
They are very difficult to take pictures of, as they are constantly moving incredibly rapidly and they are as minuscule as a butterfly. Beautifully coloured, vibrant and dazzling, hummingbirds are an amazing gift of nature.
