Hummingbirds (L6U7)

Hummingbirds are among the smallest of birds, most species measuring in the 7.5–13 cm (3–5 in) range. Indeed, the smallest extant bird species is a hummingbird, the 5-cm Bee Hummingbird.

They are known as hummingbirds because of the humming sound created by their beating wings which flap at high frequencies audible to humans. They hover in mid-air at rapid wing flapping rates, typically around 50 times per second, but possibly as high as 200 times per second, allowing them also to fly at speeds exceeding 15 m/s (54 km/h; 34 mph), backwards or upside down.
The smallest species of hummingbird weighs less than a penny. (From wikipedia)
Hummingbirds in slow motion are beautifully epic. These tiny birds beat their wings so furiously it is hard to understand what is going on. So Sam Hume and Simon Baxter visit a very special location in Los Angeles and use a high speed camera to reveal some of the hummingbirds' most intriguing behaviour.
