You might think that flapping such large wings would make a ton of noise, defeating the purpose of being stealthy. Generating this lift force, however, requires owls to flap their large wings. To take off in flight requires a great amount of lift force to get off the ground, and more energy is needed to stay in the air. Silent flightĪs nighttime predators, owls rely on their silent hunting tactics to successfully capture prey. Due to its design and mimicry of hummingbird musculoskeletal structure, the Nano Hummingbird is capable of complicated flight manoeuvre. These drone advancements can be applied to weather monitoring, parcel shipping and even cinematography. With more research on hummingbird flight precision and its everyday implications, having drones that can effectively examine natural uncharted territories might happen sooner than previously believed. These drones can access unreachable locations and gather information via an attached video camera. The Nano Hummingbird is a drone device that mimics the flight of hummingbirds to gain an agile, manoeuvrable edge. Defense Advanced Research Projects Agency. ![]() When scientists looked at how the muscles and bones of hummingbirds come together to generate fast, precise flight in these tiny birds, they became interested in whether these same mechanisms could be engineered.Īn example of this inspiration is AeroVironment’s Nano Hummingbird, developed as a prototype for the U.S. ![]() By working together, the muscles and bones of hummingbirds allow for hovering and sideways and backwards flight at speeds that top 50 km/hr. This wing beat style is made possible by continuous “wrist flicks” from their shortened arm bone - a unique characteristic not found in any other bird species. In order to hover, hummingbirds flap their wings in the shape of a figure eight. Additionally, the adaptation of a long chest bone is the perfect surface needed for wing muscles: the larger the surface of the chest bone, the more muscle can be connected. Hummingbirds need large amounts of energy to fly continuously and gather food. Slow-motion video of hummingbirds in flight. High wing beat frequency allows hummingbirds to perform their unique hovering flight, especially during their summer visits to your flowers and backyard feeders. Hummingbirds require large wing muscles to continually flap their wings quickly during flight, known as a high wing beat frequency. The secret lies within their muscles and bones. But many types of birds have large wings, so what sets hummingbirds apart when it comes to their amazing manoeuvrability? They possess small, lightweight torsos with relatively large wings that allow them to fly remarkably fast with incredible precision. Hummingbirds are some of the tiniest birds in the world. In both cases, biomimicry draws inspiration from natural inventions to design and improve upon our current technologies. Or an owl’s stealthy flight, which has informed the design of silent and efficient wind turbines. Take, for example, the swift and precise flight of a hummingbird that has helped us develop flying devices that are also capable of intricate manoeuvre. These inventions are so extraordinary that we study them to apply their design in everyday technology. Specifically, I study bird flight behaviours and how relationships between body mass, wing sizes, species relatedness and other biological traits have evolved to generate the extravagant flight we see in many species. ![]() My graduate research explores some of evolution’s most impressive inventions, many of which can be found in birds. Is evolution the best inventor? With hundreds of millions of years of work and the natural world as its canvas, it would seem so.įrom the water-retaining camels of the desert to the long-flying albatrosses of the sea, evolution has shaped the abilities of animals to best help them survive and thrive.
