Barn Owl 2011 Prey Cam
Tyto alba

A video camera with motion detection was employed to record all prey brought to the nest box or exterior perch during the period from the the day the last egg hatched until the adults stopped providing prey at the nest box. During the early nestling phase, the camera was mounted on back of the nest box directly across from the entrance. This provided a good view of the adult entering the box with prey in its mouth. Later, when older nestlings tend to move forward in the box and block the view of the entrance, the camera was mounted outside on the barn wall, focused on the exterior perch. The photo at right shows the exterior camera mounted in a pvc tube and supplemental light provided with a 15 watt tungsten bulb. Some data was lost during this nesting, due to power failures from electrical storms. For more details of the graphs below, see the previous page
