Guard llama

Llamas are instinctively alert and aware of their surroundings, and may draw attention to an intruder by making a startling alarm call that sounds like a rusty hinge.

Guard llamas have been most common on ranches located in the Western United States, where larger predators, such as the coyote, have been more prevalent.

A gelded male of two years of age instinctively bonds with its new charges and is very effective in preventing predation.

The study found average rates of loss to predators fell from 21% to 7% after the introduction of a guard llama.

[1] In other studies, over half of guard llamas completely eliminated losses due to predators.
