or they use hidden charus all over the place to scout out the position of the dragonborn and then the charus send the location to the falmer. (cause charus are like dogs to falmer)

Smell is even sillier than hearing, it's explained as well above. Snakes use smell to detect stuff that is still, like carcasses or sedentary animals. Once a snake gets in range, they's use their eyes to aim their strikes.

Telepathic links with Chaurus? Well, never thought of that...
