Actually it's a different problem. I found that if you walk into the trigger, you can then walk away from the bird and talk to it from anywhere on the screen by pressing up.
Not sure how I've done this, but I've gotten myself softlocked. If you manage to talk to the bird at the start of the game far enough away, you'll start the fall sequence, but unable to fall. Since I'm locked in the animation, I cannot proceed! On the upside, not too difficult to reset!
