Tahukah anda ?? Kestabilan tingkat tinggi seekor "chickenS"

Chickens punya kemampuan luar biasa untuk mempertahankan kestabilan posisi kepala, sementara tubuh mereka bergerak.

Coba dicek video berikut ini

Chickens atau bangsa burung lainnya memiliki kemampuan ini karena mereka punya leher yang sangat panjang dan menyerupai letter "S".
Hal ini membuat mereka menjaga kestabilan posisi kepala saat mereka berjalan (tubuh bergerak).
Semua burung punya leher yang sangat panjang, walaupun terlihat pendek, dikarenakan tertutup bulu yang sangat tebal.

Why do birds bob their head when they walk?

Watch chickens or pigeons walk around on the ground, and you can't help but notice that they move their heads back and forth as they walk. If they speed up their steps, the head bobbing speeds up too. Not all birds do this, but many that walk instead of hopping do.

This head motion looks silly, and it may look like random head waving, but it's not. If you look closely, or take videos and watch them in slow motion, you will see the head actually stays in one place while the body walks past it. It then is jerked forward and put in front of the body and the body walks past it again.

What this behavior does is keep the head still and in one spot as long as possible. By keeping the head still, the bird gets a better look at the world and is able to see things more clearly. It can focus on one spot for a longer period of time.

This tactic is especially useful for seeing motion. Birds are very interested in moving things: small moving objects to catch and eat (such as insects), and large moving objects that might be dangerous and need to be avoided (such as hawks). Detecting movement while you are moving is hard; the best way to do it is to stand still. The head bobbing of birds allows them to detect movement while they are moving too.

Why don't other animals move their heads like this? Have you tried it? Although you, too, can look silly while you walk, your neck just isn't long enough to keep your head still for long enough to make a difference. Birds, though, have surprisingly long necks. Even birds that look like they have no necks - such as doves, chickadees, or quail -- actually have long necks. Much of a bird's neck is coiled in an S-shaped curve hidden by the neck feathers. They can extend their necks out pretty far when they want to. It is this long, flexible neck that allows birds to bob their heads effectively when they walk.

Kemampuan "chickens" ini sudah diadopsi oleh beberapa brand dunia, diantaranya LG dan mercedes benz.
