Many pet birds, African grays in particular, are thought to use head bobbing as a means of attracting attention, either for play or in the hope of getting treats. Head bobbing is also thought to be a help to larger birds in the wild for visualizing their surroundings and pinpointing the location of food.
i like owls very much. people think owls are smart because they have large eyes and see alot, owls can not move there eyes they have to move there heads. that's were people think owls can turn there heads in a 360 degree angle but they can only go up to 190.
All owls will tilt their head to hear better. Owls have uneven ear slots on the side of their head, meaning that one ear mat be up towards the top of their head and the other will be towards the bottom. Owls tilt their heads to get the same amount of noise in each ear so they know what direction the noise is coming from.
I've noticed that my ducks bob their heads and quack lowly when they're mad. This usually happens when turn on the back light at night and wake them up.

Poor Bob doesn't do much strumming these days but when he was alive he was a down, down up down up up kinda guy. Sorry, I just couldn't help myself.
You are probably thinking of Bob Jones.
