"Herd animal. Fattens over time. Fattens faster if tasked on a Livestock Pen, Farm, or Village."
In Age of Empires III, Llamas can be found in the wild in the maps Andes, Pampas, and Araucania, and in some iterations of Araucania, each player starts with six of them. They fatten faster than Cows, and fully fattened they can be slaughtered for 400 food.
Portuguese and Spanish players can send the Llama RanchingHome City Card, which will enable them to train Llamas from the Livestock Pen in a similar manner to the Sheep and the Cow for other civilizations. Compared to the other livestock, a Llama costs slightly less resources to make at 70 food; however, it takes longer to train them.

Llamas resemble shaggy camels without humps. They live in herds and are sometimes added to herds of sheep, goats, and even geese to protect these animals from predators. Humans use them as beasts of burden or sources of meat, milk, and wool. When aggravated or making displays of dominance or displeasure, llamas can spit up greenish stomach acid. They have thick, wooly coats, commonly brown, black and white or piebald. Llamas include four species of related animals - two (the llama and the alpaca) are domestic, and two (the guanaco and the vicuna) are wild."
The llama is the domestic descendant of the guanaco.
The llama is the largest domestic animal native to the Americas, where they were used for wool, meat, and burden. They were not ridden as they are still too weak to carry an adult for long (unlike what is shown in the cutscenes of the Pachacuti campaign). Nevertheless, when the Incas first saw Spanishhorses for the first time they assumed that horses were animals similar to llamas. This probably explains why they were not as intimidated by cavalry as other Native American peoples.
