Ocorn bird call

A simple remix that allows the original design to be a smaller one hole bird call. The thumb hole is large enough to easily partially cover it and do more pitches than just an open and closed. It was also necessary to add a "hat" to it so that the minimum wall thickness is met for the shrunk design, a problem I had on the previous remix.
The two halves are super glued together.

The longer version sounded a bit deep to me, so I also uploaded a shorter version which should sound more "birdlike".
