Watch hummingbirds -

The hummingbird family, also known as the bees, is a small bird family with more than 300 species that live all over the world.

This species is famous for its colorful and small-colored fur, in which the smallest hummingbird is a hummingbird bee in Cuba with a weight of only about 2gr.

Research by American scientists published in 2006 showed that hummingbirds receive 75% of the lift from flapping their wings, the remaining 25% is from the flapping process, while in other birds, the lift force can get 100% thanks to flapping wings. Thanks to this feature, hummingbirds can hover above a flower for a long time without falling.

Inspired by this bird, the United States has developed a spy plane that can fly up and down vertically, fly horizontally, forward and backward. In addition to scouting purposes, it can also help find victims in buildings that collapse or detect dangerous chemicals that leak.
