Can cockatiels eat avocado?

Toxic

No – toxic. Cockatiels should never eat avocado. Avocado is toxic to birds. The Merck Veterinary Manual names cockatiels among the susceptible animals, and the AAV reports cockatiels with breathing difficulty after eating avocado. The AAV’s cockatiel care sheet lists avocado among things cockatiels must not get access to. Every part of the plant and fruit can cause harm.

Good to know: According to the AAV, there is no established treatment; if a vet sees the bird very soon after it ate avocado, some may still be removed from the crop. The RSPCA (highly poisonous to parrots), Purdue, NC State and RSPCA Australia all warn against avocado 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.

  • ASPCA Animal Poison Control: (888) 426-4435 (a fee may apply)
  • Tell your vet what your cockatiel ate, how much and when.
