  ABSTRACT: Managing livestock near Yellowstone National Park has become an increasing challenge since conservation of wolves restricts ranchers from interfering. Even though wolves are beneficial for the ecosystem, rising predation incidences on livestock (depredations) create animosity in local farmers. Temperament selection of cattle, measured by the facial hair whorl pattern (HW)1, occurred during the last 15 years and the industry prefers calmer temperament animals. Six HWs occur in cattle (high, middle, low, abnormal, multiple and none), which are mutually exclusive and can be identified by using the eye-line as a reference point. We analyzed depredation of calves near Council, ID in 2011. A herd of 588 Black Angus × Charolais crossbreds (age range: 5 - 17 years) was observed. By analyzing the HW and age of cows in relation to depredations, we could identify a connection between these three factors (P
