Can cockatiels eat onions?
No – toxic. Cockatiels should never eat onions. The AAV says plants in the onion family, such as onions and garlic, are toxic to many species. The Merck Veterinary Manual lists onions among foods not to feed birds, and RSPCA Australia calls them dangerous.
Good to know: Green onions, chives and leeks belong to the onion family too.
Did your cockatiel eat some?
If your cockatiel ate some or seems unwell, the AAV says to get help from an avian vet immediately, even if you only suspect it.
