A new method of repairing and renovating ecological specimens of birds was described in this paper. The method included following steps: 1. taking the skin carefully from the specimen restored for a long period time; 2. intenerating and cleaning the skin; 3. repairing and seaming the skin; 4. daubing the preservatives; 5. making and putting carriage; 6. filling the materials and seaming; 7. reshaping and fixing the specimen. This method is easy to manipulate and can restore specimens of endangered birds kept for a long period time. It can also reshape the specimen which is not treated properly. Soaking the skin can keep its elastic and prevent feathers dropping. Pearl cotton used as filling materials is cheap and environmental friendly, as well as prevent specimens from damage made by worms.
