Abstract


Diurnal grouping in a population of Pyrenean chamois Rupicapra p. pyrenaica was studied by direct observation on the edge of their westernmost distribution. The whole area occupied by a population was surveyed by performing monthly fixed transects over one year. The size of 214 groups ranged from 1 to 54. Both size and composition were quite variable and differed between seasons and habitats. Groups were generally very small (45% of only one animal, median: 2; P75=4), which is characteristic of small and low density forest-dwelling populations. Groups appeared to depend strongly on the annual biological cycle, food distribution and vegetation cover. The spatial segregation between males and females was only evident in the summer, when solitary males mostly occupied the forest and females with kids lived on open pasturelands. All the general patterns on size and composition of the groups occurred in this population.
