Hi! It is very important that you lift his wing and check if there isn't residual bleeding. Birds do not have a rich blood reservoir like we do and can bleed out overtime or get dangerously anemic with residual bleeding. Another thing about blood feathers is that if the bird finds the clot agitating, he can pick on it again - hence resuming the bleed. Have styptic powder on hand - if you find that he is still bleeding apply styptic powder or cornstarch/flour/baking soda/baking powder with a sterile gauze or cotton swab, and take him to an avian vet for blood feather removal. If your avian vet is not immediately available, make sure you WATCH him after you have stopped the bleeding to make sure he isn't picking on the wound until you can take him to the vet. Best of luck!
