The largest cockatoo, the black palm cockatoo or goliath cockatoo, is strikingly beautiful. This species is not naturally affectionate. However, with extensive training, hand-fed black palm cockatoos can make excellent, tame pets. This species thrives when it is socialized. Like other cockatoos, it craves regular interaction with its owners. This bird’s large size, beak strength, and uneven temperament make it most suitable for experienced bird owners. These bold parrots require a fearless owner to match.
