My 1 year old cockatiel, Oscar, is full flighted and loving it, but the there have been some close calls ( someone coming in through the door while Oscar is flying around the house ). He also has been flying up to the ceiling fan ( the fan is never turned on ) and perching there. Usually I can coax him down with his favorite blanket, but sometimes he gets into one of those " nah I think I'll sit here for a while" moods. I have been thought about getting his wings clipped, but I think he might get depressed, and I think flying is very good exercise for him. On the other hand, I'm worried about his safety. What do you guys think?
