Cockatiel does not want to fly
Recently my 20 year old cockatiel does not want to fly. I leave the cage door open when I am at home, and he used to come out and fly around. I try to encourage him to fly but with no success. At a check up recently my avian vet said he was a bit overweight - he only weighs 4ozs. I am trying to reduce his weight and have cut out the usual cockatiel mix with sunflower seed, oats, etc., I have been giving him canary seed along with budgie seed, I buy the packet of budgie seed for the added vitamins. He doesn`t always take the apple,carrot,brocolli I put in his cage but will always take a cornflake, I only give him one a day. I checked his weight and he is still the same. What is best to do so that he gets some exercise?
A cockatiel that weighs 4 ounces is approximately 120 grrams. Very likely, your bird is overweight, as you have suggested. I would recommend that you work with your veterinarian to formulate a weight reduction plan that incorporates enrichment of activity (foraging, etc) in combination with a functional reduction of calorie consumption per day. It is probably a bit too intrusive and less appropriate to “force” your bird to fly, as stated.
