### Identification Compact and woolly, the Alpaca (*Lama pacos*) is the smaller, more refined cousin of the Llama. Standing roughly 35 inches at the shoulder, the easiest way to distinguish them in the field is by their silhouette: look for straight, spear-shaped ears, which lack the distinct "banana" curve of a Llama’s ears. Their faces are shorter and blunter, often sporting a heavy "top-knot" of fiber that gives them a soft, rounded appearance. While their wild ancestor, the Vicuña, is strictly cinnamon-colored, Alpacas display 22 recognized natural shades, ranging from snowy white and silver-grey to deep mahogany and jet black.
### Habitat & Range These resilient camelids are specialists of the high-altitude Andean Altiplano. You will find them grazing in the marshy *bofedales* (high-altitude wetlands) and windswept paramo grasslands of Peru, Bolivia, and northern Chile. They thrive in the thin air between 11,500 and 16,000 feet, where they have evolved oversized hearts and specialized blood to navigate the oxygen-depleted environment.
### Behaviour Alpacas are deeply social, structured herd animals that rely on "safety in numbers." An observer will notice their constant vocalizations; they communicate through a soft, musical "humming." They are remarkably tidy creatures, utilizing communal dung piles to prevent the spread of parasites and keep grazing areas clean. While generally docile, they protect their personal space with a warning "spit" of stomach contents if a herd mate gets too close during feeding.
### Diet As specialized grazers, Alpacas possess a three-chambered stomach that efficiently processes tough, fibrous vegetation. They focus on native bunchgrasses and sedges. Unlike goats or sheep, Alpacas are "gentle" on the land; they have a split upper lip to delicately clip grass without pulling up the roots, and padded feet that don't erode the fragile mountain soil.
### Fascinating Fact When a male Alpaca is courting, he performs a unique vocalization known as an "orgle." It is a rhythmic, guttural gargling sound that actually triggers "induced ovulation" in the female—meaning she only releases an egg once she hears the song and mating begins!
