What specific type of vegetation do vicunas prefer to graze upon in the puna?
Answer
Tender and young grass shoots
Vicuñas are highly specialized herbivores adapted to the harsh conditions of the high-altitude Andean plains. Within their grazing range, they do not consume all vegetation indiscriminately. Instead, they exhibit a distinct preference for the most tender and young shoots of grasses available. This selective feeding behavior is a critical survival mechanism that allows them to maximize their intake of essential nutrients and energy from forage that is otherwise tough and difficult to digest.
