Alpacas will also hum in an effort to express distress or anger. This is especially true if living arrangements are changed, they are moved, or they are separated from their herd.

Can alpaca be aggressive?

Alpacas are not often aggressive. They tend to be rather laidback, especially when they are raised by a large herd that makes them behave. Even if they are aggressive, they can't do much damage. They have no teeth, horns, or hooves.
