At first glance, bullet trains, football players, and airplane turbulence might seem to have little in common. However, they share a surprising link: birds. With around 10,800 species, birds have evolved unique adaptations to thrive in their environments. These adaptations offer valuable lessons for solving human challenges through a concept known as biomimicry.
Birds have developed specialized features to suit their ecological niches. For instance, ospreys have reversible toes and spiny feet to catch slippery fish, while the American coot’s feet combine traits of ducks and chickens, enabling them to traverse various terrains. The shoebill stork’s oversized beak allows it to capture and decapitate prey like lungfish and young crocodiles.
Designers and engineers have taken cues from these bird adaptations to address human problems. A prime example is the Shinkansen bullet train in Tokyo. In the 1990s, the train’s bullet-shaped nose caused sonic booms when passing through tunnels. Eiji Nakatsu, a designer and bird enthusiast, solved this by modeling the train’s nose after a kingfisher’s beak, eliminating the sonic boom and boosting speed by 10%.
Biomimicry extends beyond trains. Dr. David Smith designed a football collar inspired by woodpeckers, whose unique tongue adaptations help prevent brain injuries by regulating blood pressure. In aviation, researchers at the University of British Columbia are studying gull wing physiology to create airplane wings that can adjust to changing wind conditions.
Engineers need to understand how bird form influences function. While biologists study birds’ ecology and evolution, engineers view birds as blueprints to grasp their mechanics. Dr. Chad Eliason, a post-doctoral fellow at the Field Museum, merges these fields by examining kingfishers, often seen as biomimicry stars. He transforms preserved bird specimens into mathematical models to explore how kingfishers dive and how this knowledge can solve human problems.
Birds exhibit both form and function, with significant variability even within a single group. Although kingfishers are known for fishing, only a few species actually dive for fish. This diversity often leads to naming conventions based on charismatic behaviors rather than accurate descriptions.
Dr. Eliason’s research suggests that kingfishers might be better models for studying brain injuries in football players than woodpeckers. By comparing species with head-smacking behaviors to closely related species without such behaviors, researchers can uncover the physical structures necessary for safe high-speed diving.
To explore the link between behavior and anatomy, researchers measure both the beak and the brain case. They use CT scanning technology to create 3-D models of bird anatomy, allowing for detailed analysis of physical traits. This method provides a clearer understanding of how evolution shapes these characteristics.
The process involves placing preserved specimens in a scanning device to create digital representations of their anatomy. This technology enables researchers to conduct fine-scale measurements and comparisons between different species, enhancing our understanding of their adaptations.
In addition to CT scanning, researchers can simulate diving behaviors using mathematical models and 3-D printing. This innovative approach allows for experiments that measure forces experienced by birds during dives, providing valuable insights into their functional adaptations.
The use of museum specimens in this research highlights the unexpected ways in which historical collections can contribute to modern scientific inquiries. By examining the adaptations of birds, researchers gain a deeper appreciation for biodiversity and the potential applications of these insights in design and engineering.
This exploration of birds as models for innovation underscores the importance of understanding and preserving biodiversity. As we continue to learn from nature’s ingenious engineers, we can develop solutions that are both effective and sustainable.

**Sanitized Transcript:**
Bullet trains, football players, and airplane turbulence may seem unrelated, but they could share a common solution: birds. There are roughly 10,800 species of birds, each occupying its own niche in an ecosystem. Birds have evolved various forms to serve different functions. For example, ospreys have reversible toes and spiny feet that help them catch slippery fish. The American coot has feet that combine features of ducks and chickens, allowing them to navigate diverse terrains. The shoebill stork has an oversized beak that enables it to capture and decapitate prey like lungfish and young crocodiles.
Some designers and engineers draw inspiration from bird adaptations to address human challenges, a concept known as biomimicry. A notable example is the Shinkansen bullet train in Tokyo. In the 1990s, designers faced a problem: the bullet-shaped train created sonic booms when passing through tunnels due to air compression. Fortunately, designer Eiji Nakatsu, an avid birder, modeled the train’s nose after a kingfisher’s beak, resolving the sonic boom issue and increasing speed by 10%.
In another instance of biomimicry, Dr. David Smith designed a football collar inspired by woodpeckers, whose tongue adaptations help prevent brain injuries by regulating blood pressure in their brains. Aviation also benefits from bird-inspired design. Researchers at the University of British Columbia are studying gull wing physiology to develop hinged airplane wings that can adapt to changing wind conditions.
Engineers require a deep understanding of how bird form influences function. While biologists focus on birds’ ecology and evolution, engineers analyze birds as schematics to understand their mechanics. Dr. Chad Eliason, a post-doctoral fellow at the Field Museum, combines these fields by studying kingfishers, which are often seen as the stars of biomimicry. He transforms preserved bird specimens into mathematical models to analyze how kingfishers dive and how this knowledge can inform solutions to human problems.
Birds exhibit both form and function, and even within a single group, there can be significant variability. While we refer to kingfishers as a group, many do not actually eat fish; only a small percentage engage in plunge-diving for fish. This diversity leads to a common naming convention based on charismatic behaviors rather than accurate descriptions.
Dr. Eliason’s research suggests that kingfishers may be better models for studying brain injuries in football players than woodpeckers. By comparing species that exhibit head-smacking behaviors with closely related species that do not, researchers can gain insights into the physical structures necessary for safe diving at high speeds.
To study the relationship between behavior and anatomy, researchers measure both the beak and the brain case. They utilize CT scanning technology to create 3-D models of bird anatomy, allowing for detailed analysis of physical traits. This method provides a clearer understanding of how evolution shapes these characteristics.
The process involves placing preserved specimens in a scanning device to create digital representations of their anatomy. This technology enables researchers to conduct fine-scale measurements and comparisons between different species, enhancing our understanding of their adaptations.
