There have a big reason that describe why do hummingbirds hum? These colorful hummingbirds produce their sounds by moving their wings as they move from side to side. This tiny aerodynamic marvel has two wing beats of about 70 strokes in 25 seconds, which is over 4,000 miles per minute.



Answer of questions Why do Hummingbirds hum

Hummingbirds hum sound by wings

However, researchers have understood exactly how these wings make their sounds by looking closely at each hummingbird.  As the birds move around and fly, the sounds of their wings are very well understood.

In this way, scientists have succeeded for the first time in measuring the cause of the sound produced by the flapping wings of a flying bird. The buzzing of hummingbirds is usually caused by pressure differences between the top and bottom of their wings. Changes in size and orientation accompany the flapping of their wings.

The pressure differences hummingbirds experience over their wings are essential in flight because they provide the net aerodynamic force that enables hummingbirds to fly and hover.  When you will read the hummingbird species or identifications, you totally understand the fact.

Scientists from Stanford University studied 6 species of such birds.

 One by one, the birds drink sugar water from a fake flower in a special flight chamber. Around the chamber, invisible to the hummingbird, special cameras, microphones, and pressure sensor devices were placed to record each wingbeat.

In contrast to many other species of birds, a hummingbird generates a strong upward aerodynamic force during both downward and upward wing strokes. Both of these pressures mainly contribute to hum. However, it can be seen that the difference in upward lift pressure is the primary source.

“This research shows that through advances in technology, in this case, collaboration with a company, innovations are possible, enabling scientists to make discoveries about how organisms do their work – with applications that benefit society in many ways. can benefit,” said researcher Kathryn Dixon, who is a program director at NSF’s Division of Operations. Integrative organismal systems made major contributions.

Here, scientists create a 3D model that shows how hummingbirds move and generate energy as they swing their wings. Video and audio recordings of a bird in motion are combined to measure the energy produced There, the team found that the humming sound in the upstroke of the hummingbird wing beat was easily detected by the instrument, which gave the birds an extra force or boost in lift – unlike the upstroke in the wing beats of other birds. And through this the researchers present their research correctly.
