Herons and egrets capture prey using rapid strikes in which the head is propelled forward with remarkable speed and precision. One of their most distinctive features is the pronounced kink visible along the neck. This unusual morphology has intrigued scientists for over a century, yet the functional significance of many features of the heron neck remains uncertain.

This project invites viewers to explore the relationship between form and function through a series of interactive physical and digital models. Three physical articulated neck models represent alternative cervical designs that differ in vertebral proportions and joint mobility, with threads of varying stiffness representing differences in flexibility throughout the neck. A highlighted mid-neck element draws attention to a vertebra that is unusually elongated in herons and has long been hypothesized to play an important role in feeding strike behavior. By manipulating the models and observing how different designs move, viewers can investigate how anatomical features influence flexibility, reach, and joint coordination while engaging in the scientific process of observation and hypothesis formation. In an accompanying website the physical form becomes a digital instrument. A slowed-down video of the strike allows users to closely observe these precise movements. Using a drawing tool resembling the physical model, users are encouraged to create their own movements freed from the constraints of muscles and joints.

This project is an invitation to play, learn, and investigate how variations in vertebral proportions lead to different and surprising outcomes.

"The project began in an open-ended way. We had one specific thing we wanted to convey — the strike motion of the heron and the joints that make it possible — and we explored different routes that would let us make something visual and interactive. We gave ourselves some material options (markers, LED lights, paper, acrylic) and directions to explore (physical, web, video), and the project organically took its form from trying different things."

"It was really fascinating to participate in a long-term research project and be given such a rich body of information and media to work with. I was intrigued by how much close observation and fieldwork went into understanding one very fast and precise movement. It taught me what staying with a curiosity or question over an enduring time could yield, and it allowed me to embrace that in my own artistic process too."
