Beauty’s Bionic Bald Eagle Beak

A few years ago, an Alaskan Bald Eagle was shot in the face, disfiguring her and obliterating the upper half of her beak. Rescue workers tried to rehabilitate the bird, whom they named Beauty, in hopes that her beak would grow back. It did not. Beaks are essential for preening feathers and feeding, and Beauty’s future was looking grim. Lucky for Beauty, she was taken under the care of Idaho raptor specialist Jane Cantwell, who spoke of Beauty’s case during an educational talk she was giving. In the audience happened to be mechanical engineer Nate Calvin, who was moved by the story and inspired to help. In the first attempt to create a prosthetic beak, Calvin made a mold of the missing upper beak, laser-scanned it, fine-tuned it in a 3D modeling program, and created the prosthesis of a nylon-based polymer.

The procedure to implant the prosthesis is likened to fitting a patient with dentures, and there was a dentist on-hand to help. They started by placing a metal mount on Beauty’s existing beak, much like how a dentist would fit a post for a crown to anchor. Then the prosthetic was fitted on, and amazingly Beauty was able to preen and drink water that night.

This story is not exactly breaking news, but it is definitely an unlikely and inspiring tale of engineering to the rescue!

Here is a video profiling the case:

    1. I stand corrected James — this is not technically bionic. Apologies — my love of alliteration got the best of me here :)

    2. Bionic is defined as having artificial body parts.

      While this tends to have more emphasis on mechanical parts, it is not required. You are correct that the beak is a prosthesis, but it is still technically bionic. :)

      Just throwing in a random bit of info from an engineering student. Have fun. :D

  1. It’s amazing to hear about the variety of technologies used to make the prosthesis. But yeah, it’s not a bionic thing. Great story though. Glad I got to read up about it, and it’s inspiring for my interest in prosthetic fabrication techniques. Especially liked how his own personal dentist got involved. Way to go team!

    1. Someone shot a helpless creature in the face and folks did their best to help it recover.

      Species was simply a detail, not the story. Grow up a bit.

    2. Reese58 please don’t feed the trolls (Pelt).

      The tactic is to never get angry at them, rather engage in supportive dialogue directly with the parent poster with your more positive view. This way trolls get buried in good comments. Eventually the trolls either wise up or get bored and leave.

  2. Everytime i see this kind of prothesis (seen one on a Japanese Stork and a German Swan in the last years) it makes me smile. It shows the great humility and respect for our fellow being.

  3. Absolutely beautiful story. I am so glad there are individuals out there who take their love of animals and their talents, and create a better, stabler life for mistreated animals and birds alike.

I was an editor on the first 40 volumes of MAKE, and I love shining light on the incredible makers in our community. In particular, covering art is my passion — after all, art is the first thing most of us ever made. When not fawning over perfect word choices, I can be found on the nearest mountain, looking for untouched powder fields and ideal alpine lakes.
