Cockatoo games.

[Digger...]

So I've trained a few cockys to pull the cork out to get to the seed in the bottle,

There's 2 ways they've learnt to get it out, when it's full they roll the bottle around with there beaks to make the seed come out. When its half empty and rolling won't work they stand the bottle up and the knock it over, the kinetic energy knocks the seed out.
