Is thyme oil harmful to birds?

Thyme oil can be harmful to birds if ingested or inhaled in significant amounts, as essential oils are generally potent and can cause respiratory distress or gastrointestinal issues. Birds have sensitive respiratory systems, and exposure to strong scents or oils may lead to adverse reactions. It's best to avoid using thyme oil or any essential oils in environments where birds are present. Always consult with a veterinarian if you're unsure about the safety of any substances around your pets.
