While this answer might explain a way by which babblers escape their predators, it does nothing to explain why the birds would make a noise that alerts the predators to their presence in the first place.

This explains why it might be a good idea for babblers to make noise when predators are near. Predators are intimidated by large numbers of babblers, and only by hearing their collective call do predators become aware that there are many babblers nearby.

The fact that there are multiple types of predators preying on babblers does nothing to explain why the babblers would want to call any predator’s attention to their presence.

This may seem to mitigate the potential damage of the babblers’ loud call—maybe the predators can’t hear them well anyway?—but it does nothing to explain why the babblers would want to make any noise at all in the presence of predators.

Even if the babblers’ call tells predators that other prey are nearby, it still also proves that the babblers themselves are there. Predators could easily decide to eat the babblers instead of the other animals, and this answer doesn’t explain why babblers would take that risk.
