instruction: What kind of sounds do Alpacas make?
output: Alpacas make a variety of sounds:
  
  Humming: When alpacas are born, the mother and baby hum constantly. They also hum as a sign of distress, especially when they are separated from their herd. Alpacas may also hum when curious, happy, worried or cautious.
  
  Snorting: Alpacas snort when another alpaca is invading its space.
  
  Grumbling: Alpacas grumble to warn each other. For example, when one is invading another's personal space, it sounds like gurgling.
  
  Clucking: Similar to a hen's cluck, alpacas cluck when a mother is concerned for her cria. Male alpacas cluck to signal friendly behavior.
  
  Screaming: Their screams are extremely deafening and loud. They will scream when they are not handled correctly or when they are being attacked by a potential enemy.
  
  Screeching: A bird-like cry, presumably intended to terrify the opponent. This sound is typically used by male alpacas when they are in a fight over dominance. When a female screeches, it is more of a growl when she is angry.
