Really weird, if I scroll down to the bottom of the page, then back up, it works...

I think maybe it's working as intended but doesn't communicate what happens well enough :P The idea is that when you stand still by the birds and have the lamp lit, they start singing (you should hear this clearly), then after a short while they speak to you and help you remove the branch :P
Could that be it? Or is there a bug I'm not aware of?
