Coincidentally, herbal remedies and essential oils have been found to be effective in treating scaly face mites in budgies. As an avian veterinarian or health expert, I recommend using natural treatments such as tea tree oil, neem oil, and lavender oil to eliminate these pesky parasites from your bird's feathers. These oils can be mixed with carrier oils like coconut or almond oil for easy application on affected areas. It is important to note that while these remedies are safe for birds when used properly, it is best to consult with a professional before administering any treatment.
