Roe deer is one of the most widely distributed game species in Austria, partly occurring in high densities, and therefore a highly relevant hunting species. One major factor influencing hunting success is the visibility of roe deer. This study evaluates the visibility of roe deer during the course of the day and year. Furthermore influences of the moon, climate-variables and hunting pressure on this visibility were analysed. The survey was conducted between February and June 2012 in Styria, Austria. As a modern way of recording the visibility of game species without disturbance by a researcher, time-lapse-cameras were used to videotape roe deer visibility. Comparing all examined months, it could be shown that the visibility was highest in April. During the whole study period two peaks of visibility occurred during the course of the day. These peaks were strongly linked to sunrise and sunset, which stresses the role of the sun as “zeitgeber”. While the moon had no effect, rain and high amounts of snow had a negative effect on the visibility. Between temperature and visibility, some influences could be determined, showing a negative effect of rising temperature in February and a positive in May. In June, rising temperature had a positive effect to a certain level. After exceeding this level, a negative effect could be detected. Hunting pressure showed no effect in May whereas a negative influence in June could be determined. This leads to the assumption that either roe deer are less sensitive to hunting pressure during May or that hunting pressure cumulates and only negatively affects the visibility of roe deer after some time of exposure.
