Mammal Surveys
Predator Cameras


Last update: 2002 April 16

We are using predator cameras to determine which animals prey on bird nests.

A camera is connected to a switch that is connected to a plasticine egg. When a predator pulls the egg, the camera photographs it..

Cameras will be left out for several days.
