Learning this llama language is one of the joys of ownership. Humming is a common manner of communication between llamas and indicates a variety of moods from contentedness to aggression. Another interesting llama expression is the shrill, rhythmic alarm call emitted at the sight of a strange animal or a frightening situation. Whether viewed in a pasture or glimpsed in the wild, all llamas have a striking beauty owed to their elegant wool and graceful posture. Llama wool ranges from white to black, with shades of gray, brown, red and roan in between.
Markings can be a variety of patterns from solid to spotted.
Mature llamas weigh an average of 280 to 350 pounds, but can range from 250 to 500 pounds. Full body size is reached by the fourth year, and while there are no obvious differences between the sexes, males tend to be slightly larger. They are long-lived, with a normal life span of 15 to 20 years. These unique animals are rewarding, both mentally and financially. One can quickly become a member of the growing ranks of llama lovers.
