Odd bird

I was outside today, watching the leaves fall.

I saw a squirrel, but couldn't be bothered going over to it.

I saw a Magpie and blinked at it.

Then something weird landed on the grass.

It was bird-shaped, had wings, was green and red... and headbutted things.

It hopped along and headbutted the grass.

It hopped to the mud and headbutted that.

I thought about chasing it, but it flew up to a tree... then started headbutting that.

I then got a bit scared.
It was too weird to chase. If it headbutts trees, I don't know what else it could do.

I went inside and requested tuna from my human.
