Beaks are extremely important to birds, allowing them to hold objects and feed themselves. One can easily imagine the problems that a blue and gold macaw named Max experienced, when his beak was pulled off after two fights with other birds. Human caretakers helped him eat again, and when his remaining lower beak grew too long, they regularly shortened it so it was the right size for his tongue.
In search of a long-term solution, a South African team of veterinarians, doctors and other professionals led by Prof. Gerhard Steenkamp worked together to design and attach a 3D-printed beak for Max. As has been previously covered on Flayrah, many other animals have also received prosthetics when they've needed them.
