Sing to control the bird’s height. Each tree has a single hole—match the target pitch
as you approach to pass through. Your microphone is required. Camera is optional.
Use a steady tone (like “ahhh”).
Try to match the target pitch number as the bird nears the hole.
If you miss, the bird bounces back and tries again.
Tip: use headphones to avoid feedback.
If you don’t see a permission prompt, check your browser’s site settings for microphone access.
