Meet Hercules Inexpectatus, an extinct prehistoric parrot that stood as tall as a toddler. That's about three foot or one metre tall, which is pretty impressive for any bird. It is believed that the species, dated to 20-million years ago, could neither fly nor climb, being predominantly ground-based. One thing is certain though, when this polly says he wants a cracker, best give him one asap!
