Location: Sky Island
Once here, you will see statues that rotate. They also shoot laser beams when you're in close proximity. There is also few enemies here. So what you need to do, is attract the attention of a nearby bird and lure it near the laser beam. Run around in circles around the statue, and the bird will follow until it gets hit. Simply repeat and the bird will die.
Let me know if you find an easier way to get this done.
