2013 Calving season

The 2013 calving season was unusually short and early, with half of calves born before June 1st, compared to the long-term average of 26%. Remarkable was also that a calf was born to a 2 year old female, which has happened only a couple of times during the long duration of the study. In total of 94 calves were born, of which 78 were caught, measured, sampled and marked.
