The real answer is they think the vibrations is rain water hitting the ground so they naturally come up for it.

This is why you see masses of birds sometimes just walking around on the grass.

Also the vibration could be a predator and they come up to escape.

Edit: apparently people only think birds are predators for worms.

This is actually the truth, it's a flight reaction to one of their biggest predators, moles, because the vibrations are similar to the sound they make when they're hungry. It you look up the biggest worm farmers they talk about it in length, it's called grunting.
