Does an alpaca squawk

Answer 1

No, alpacas don't squawk. They hum to communicate with others or if they are about to make a move to protect they will sort of gurgle in their throats to warn you. When they gurgle I would back of sharpish because it's a sign of bringing up regurgitated food in order to spit.

Answer 2

Not exactly. They hum, whine, whistle, and make angry sounds somewhat like drawn out belches when they're in a fighting mood.
