Sparrow That Feeds On The Nectar Of Flowers Is Like a Bee

While I was watching a documentary about birds, a small bird caught my attention as it flew around one of the flowers to suck its nectar. What amazed me was its speed in flying. It was very fast and difficult to see because it was small and very fast. It is called the Hummingbird, where these birds feed on flower nectar and small insects. It weighs 1.8 grams and is 5 centimeters long.
These birds are called hummingbirds because of the hum they emit from their wings, which move at a rate ranging between 60 and 70 movements per second for the smallest species. This bird has the advantage of being able to fly backwards, unlike the common forward flight in birds. It is worth mentioning that the dynamic movement of the wings enables it to generate lift force when the wing moves from top to bottom and vice versa. The secret lies in the twisting wing joint.
