Having a bird in your home is almost similar to having a toddler around – they love to check new things out by putting them in their mouths. Birds are also very social creatures that seem to enjoy sharing meal times with their companions, wither other birds or human owners. And while you may not necessarily have what you consider to be poisonous around you, some common foods that are safe for you may be toxic for your winged pets.
If it's possible your bird may have ingested a substance that may be poisonous for them, then you should seek out a vet as soon as possible.
