So I have a friend of mine with a redneck parrot. I noticed even if I move the bird in any direction his head remains in a fixed position.

Is this a common characteristics of all the birds or only in parrot family.?

    this is common in birds they need to see where they are flying,have you seen the head of cats when they are running,that is just as impressive! Feb 14 '18 at 11:30

Its not just parrots.

Or Chickens

And pigeons bob their heads for the same reasons - unlike humans, who adjust their eyes to stabilise their vision, birds shift their heads - or as the paper I'm looking at says

This has led to the view that the pigeon’s head-bobbing is an optokinetic response to stabilize the retinal image during the hold phase

Here's a pretty good article on the topic that I vaguely referenced

  • Thanks @Journeyman Geek. It's amazing to see how nature has its own stabilization unit for our feather friends.
