An injured hornbill whose beak was snapped off can eat again after vets fitted a prosthetic replacement using a 3D printer.

The adult bird was found sprawled on the ground with a broken wing and its lower bill missing in Kanchanaburi, western Thailand on April 18.

Wildlife officers are unsure how the bird was injured but believe it may have been shot or attacked by hunters or poachers then left for dead in the forest.

Vets gave urgent care to stabilise the bird but they were unable to find its missing bill.

Realising it would be impossible for the bird to eat without its signature long bill, they scanned its body and used 3D printing technology to create a prototype from plastic and reattached to the bird's stump with super-strength synthetic steel glue.

Footage from the rehabilitation centre yesterday (April 26) shows the bird - nicknamed Coco - now happily tucking into pieces of fruit and seeds.

Kanokwan Taruyanont, a vet treating Coco, said: "We used the 3D printing technology to make the pseudo-bill for the bird but unfortunately it broke very quickly, so we continued our attempts to help it."

Vets said that the first prototype of the 'pseudo-bill' was broken after only half an hour but they made a second item which was refitted. They used high tensile steel glue, which is the grey solution seen around its beak in the video.

Wildlife workers are now continuing to monitor the progress of Coco as the beak could come unstuck again because of how strongly it pecks the food.

They are also looking at printing another bill with an alloy of different materials to ensure it has the best artificial limb available.

The head vet of wildlife unit at Kasetsart University, Supaphen Sripibun, said that the bird's wing condition will be more difficult to solve and it may need to remain in captivity.

He said: ''We believe the bird's wing has suffered permanent damaged in the nerves or muscles. There was no bone fracture found but the bird can't fly."
