RE: Please be careful to make sure your bird is safe!
I'm horrified at the thought of anyone letting a bird sit on or close to a fan, or using a candle when a bird is loose in the room.
Not using air fresheners and type of chemical sprays when there is a bird in the room should be common sense but I can image some owners using these without a thought for their feathered friend in its cage.
Birds are really best kept in an aviary but if people must have them inside, the home they should be responsible in their care of their birds and be aware of any dangers to health and know how to keep a bird safe.
