Isolated and domesticated llamas are more likely to have berserk llama syndrome. Berserk llama syndrome (usually shortened to BLS), aberrant behavior syndrome, or berserk male syndrome (as it is more pronounced in males) is a psychological condition experienced by human-raised camelids, particularly llamas and alpacas, that can cause them to exhibit dangerously aggressive behavior toward humans.
Abnormal behaviour in animals can be defined in several ways.Statistically, abnormal is when the occurrence, frequency or intensity of a behaviour varies statistically significantly, either more or less, from the normal value.
The term culture-bound syndrome denotes recurrent, locality-specific patterns of aberrant behavior and troubling experience that may or may not be linked to a particular DSM-IV diagnostic category. Many of these patterns are indigenously considered to be "illnesses," or at least afflictions, and most have local names.
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. Not every llama will guard, however, and it should not be assumed that because it is a llama it will guard. [4] Research suggests the use of multiple guard llamas is not as effective as one.
Guanacos have long been thought to be the parent species of the domesticated llama, which was confirmed via molecular phylogenetic analysis in 2001, although the analysis also found that domestic llamas had experienced considerable cross-hybridization with alpacas, which are descended from the wild vicuña.
The vicuña (Lama vicugna) or vicuna [3] (both / v ɪ ˈ k uː n j ə /, very rarely spelled vicugna, its former genus name) [4] [5] is one of the two wild South American camelids, which live in the high alpine areas of the Andes; the other camelid is the guanaco, which lives at lower elevations.
