A real great horse that loves the book serie warrior cats.
In the wild you can find him sitting on a stone and waving his hands and making a bird sound.
If you see a wild Birk be calm he wont attack.
The only way he would attack you is if you take his stone and destroy his headphones with it.
If you do this then you better run because he is a real strong karate fighter and he maybe even hiss at you so watch out when you meet a wild birk.
