Subject: [PATCH] Add option to make parrots stay on shoulders despite movement
Makes parrots not fall off whenever the player changes height, or touches water, or gets hit by a passing leaf.
Instead, switches the behavior so that players have to sneak to make the birds leave.
I suspect Mojang may switch to this behavior before full release.
To be converted into a Paper-API event at some point in the future?
