Abstract
A male grass parakeet lost the upper bill was presented to the hospital because of depression and anorexia. So an artificial bill made of acryl plate was fixed to the lost area. Hebegan to feed little by little after that. On the 13th day, the artificial bill came off. Then a second artificial bill made of dental resin was fixed again. It lasted for only 7 days. At that time his upper bill was noticed to have grown a little in length and could feed a small amount of feed. He showed a favorable recovery by being assisted in feeding after that.
