We applied infrared thermography to detect sika deer for culling. Deer were distinguished from ground surface or surrounding vegetation by high temperature in early morning. Using infrared thermography, we could find more deer than those without use of that device. The number of deer in a herd tend to be larger with the device than without it. The device was able to detect deer no matter where they stood behind vegetation in so far as a part of deer could be visible. Thus, we could find deer in a herd with less omission, and herd size could be estimated more correctly with infrared thermography. Using such a device could also lead to improved efficiency of culling methods by detecting carcasses easily.
