The purpose of this study was to enrich the environment for llama (Lama glama) and alpaca (Vicugna pacos) in a zoo. The zoo is located in northern Sweden (Umeå, Mickelträsk). The llama herd consists of three individuals of breed qara, two males and one female and the alpaca herd consists of six individuals of breed huacaya, one male, four females and one foal. The species lived in separate enclosures, they lived outside all year round and they had a shelter for wind and rain protection. They feed on pasture and were fed hay and pellet concentrate. A behavioral-study was carried out in April 2014, a five-day study where each of the species were observed 3 h a day, 1,5 h in morning and afternoon. The behavioral of llama and alpaca were observed individually and each behavior was observed in terms of duration and frequency. The study observed if the animals had a possibility to implement their natural behaviors in their enclosures and whether they showed any abnormal- or stereotypical behaviors that can occur in captivity. The questions I wanted to answer were: (1) what behaviors are occurring, (2) Is it possible to indicate from the behaviors if the animals are doing well or not, (3) Is there a difference in behaviors in the morning and afternoon? (4) Is there a difference between the sexes? (5) What actions should be undertaken to enrich and improve the habitat for llamas and alpacas in a zoo? The results from the study show that llamas and alpacas show many normal and natural behaviors, no abnormal-or stereotypical behaviors were visible. Some behaviors were more common in morning and some in afternoon and there were differences in behaviors between the sexes. Example for some environmental enrichment for the llamas and alpacas in the zoo was to add logs, trees, shrubs and sand piles to the enclosure.
