That's important, because although they are able to hear chainsaw noises up to a kilometer in the distance, allowing them to cover about three square kilometers, if someone were to take them, it would make the area unprotected.
To je bitno jer, iako mogu čuti  zvukove motorne pile, do jedan kilometar udaljenosti, pa tako mogu osluškivati  površinu od tri četvorna kilometra, ako ih netko uzme, to bi područje bilo nezaštićeno.
