A woodchuck


The Ergonomic Assessment of an Animal Care Facility


  Frequency of injury by season (including and excluding animal bites)

Seasonal variation in reported injuries.

At first glance, the data suggested an increase in injuries during the winter months. However, questionnaire respondents indicated greater stress during the pup season which is generally early spring. Gestating woodchucks are apparently more irritable during the winter months before giving birth. When animal bites are removed from the data, the spike of injuries during the winter season normalizes to a level much closer to other seasons. This indicates that season has little effect on the number of non-bite injuries.
