Rock cairns 1 m in height were spaced 200 m apart in lines at right angles to a straight road. Four observation huts were constructed on high vantage points within the gridded study area. By means of the cairns, one could estimate and record locations within the grid to the nearest 20 m. Once every hour the area was scanned from left to right, and the following information about each vicuna group present was recorded on a map
. Advances in the study of mammalian behavior. Mammals. Case Studies 579. Fig. 3. Pampa Galeras National Vicuna Reserve, Peru. south-facing slopes and the southern ridge. Rock cairns 1 m in height were spaced 200 m apart in lines at right angles to a straight road. Four observation huts were constructed on high vantage points within the gridded study area. By means of the cairns, one could estimate and record locations within the grid to the nearest 20 m. Once every hour the area was scanned from left to right, and the following information about each vicuna group present was recorded on a map of the study area: total number of animals, composition of group, location, number of adults and crias (young less than 1 year old) feeding, and the vegetation type being consumed. Ten to 20 groups were typically under observation at the same time. Details of intergroup aggressive encounters (territorial defense) were recorded throughout the hour. As groups left the observation zone and moved onto the adjacent ridges in the afternoon, some were no longer visible. Recordings of the location, numbers, and types of domestic livestock in the observation zone were also made hourly. Disturbed movements of vicuna groups due to activities of people, livestock, and dogs were recorded. By the end of a day, a group's continuous route of movement was obtained through these hourly.
