How do I catch the bird that's in the tree?

Hint 1 of 11:

You'll need to scare the bird out of its resting place first.

Hint 2 of 11:

The Warrior can punch the bird and it will fly up.  Notice where it goes.

Hint 3 of 11:

Through one of the holes at the top of the tree.

Hint 4 of 11:

Too bad that there are two holes; if there were only one, you could figure
out where the bird would go.

Hint 5 of 11:

So put the cork in one of the holes at the top (it doesn't matter which).
