The beak is not soft. It did not bend. The lower jaw had to have been stretched out forward, forced out by downward pressure on the top beak, just enough for the top beak to be forced down, bypassing the Lower beak. No lateral movement, just up and down. There is no bend ability in the birds beak. The whole beak went down into the throat and was protruding under the lower beak, could feel it through the neck skin. It didn’t fold or bend. Imagine if you put traction on lower beak and pushed upper beak down, it would go down throat, bypass lower beak and poke out neck under lower beak. That’s what happened. It really had to have been a one in a million physics moment.
