Singing Bird Box

If you search for "singing bird box" on Google, you'll be able to see incredible miniature mechanical birds that move and sing like real birds. I've been fascinated by them for quite a while now, and I decided to make one for this contest.

Model is made from the LEGO Mindstorms 31313 set and the LEGO Technic 42080 set. Bird can open and close its beak and move its head and tail. Unfortunately I couldn't make bellows and whistle from LEGO parts, so the song the bird sings is an audio file on the Mindstorms programable brick.

Here's a short video of it in action. Your support is kindly appreciated.
