As some of you know, I will soon be adding a four-month-old young parrot to my household. For those of you who have not heard of a hawk-headed (red-fan) parrot, Deroptyus a. accipitrinus, or who are not familiar with them, here is a video of a five-month-old parrot of that species, named Cassius. In this video, the bird is being preened by its human companion and during that process, raises the feathers of its red fan [1:02]
Is fanning the parrot equivalent of a cat's purr? Your reward for doing a good job?
