Essential oils can be toxic to birds as their respiratory system is highly sensitive to the compounds found within them. Introducing foreign, synthetic, or artificial oils or scents can quickly overload their delicate system and cause irreparable harm. Therefore it is vitally important that any bird owner who wishes to use essential oils educates themselves on all aspects of them. Essential oils themselves are not the enemy here as many birds can benefit from the introduction of “safe” oils, but it must be done with care. In this article, I will list the toxic essential oils, commercial products, and delivery systems to avoid. I will also make a few suggestions of the correct way to administer the "safe" oils. However, this is not an article about “safe” oils so I will keep those suggestions brief and to the point.
