Because hummingbirds always need to keep their bodies vertical, their wings vibrate back and forth instead of up and down. The continuous airflow generated by this vibration supports the hummingbird's body. It can vibrate its wings 80 times a second. With a slight movement, its tail can make it move back and forth. This seems simple, but it needs very subtle coordination and balance. Because the hummingbird's shoulder joint is very flexible, its wings can rotate as much as possible, so that it can fly backwards. Hummingbird is the only bird that can fly backwards.

The smallest hummingbird in the world is only a little bigger than a bee and weighs no more than two grams. Hummingbirds are similar to coffee beans It is called the smallest bird in the world. The smallest hummingbird in the world is only found in Cuba, because it is so small that when people see this hummingbird hovering over the flowers, they often mistake it for a bee flying. Scientists have discovered a phenomenon called island dwarfism.

Some of these species have encountered problems in competing for resources with larger species, so they have become smaller and smaller in the process of evolution to avoid food exhaustion and begin to compete with other kinds of creatures. Bodasad, an ecologist at the University of Copenhagen, explained that the body shape of Cuban hummingbirds is the result of the island's smallness. Obviously, there are two or three kinds of hummingbirds on most Caribbean islands. They are usually a big one and a small one.

Cuba is no exception, but it is the home of the smallest hummingbird in the world. It shares this habitat with the emerald hummingbird, which is about half the size of the emerald hummingbird, so the three hummingbirds are the smallest warm-blooded animals in the world. It lives in the virgin forests of the American continent and weighs only 2-3 grams. Hummingbirds can flap their wings continuously and quickly like bees. At the same time, it buzzes. It is very small and looks like a bumblebee flying in the air, so people call it a hummingbird.

Why hummingbirds weighing less than 4 grams can have excellent flying ability is explained here today.
