The 5-day workshop is for newbies and experienced camera trappers, and will cover basic and advanced use of camera traps to photograph wild mammals and birds. Participants may use their own scouting or trail cameras, or use a limited number of camera traps provided by the instructor. This is a hands-on workshop with evening Power Point presentations on the relative merits of "homebrew" versus commercial camera traps, triggering devices, use of flash and infrared light, extended battery use, camera security, and protection from bears and curious wildlife. We’ll discuss the role of sign and visual, scent, and sound attractants in making camera "sets". For those interested in building their own camera traps we will discuss different controller boards and P&S cameras. We will collect cameras set about a month earlier to see the results of different “sets” in the area. Prospective participants are referred to Camera Trap Codger for additional information.


Class Schedule:  Plan to arrive at the Sierra Nevada Field Campus on Sunday, July 17th. Introductions and orientation will take place that evening at 7:30. The class will begin at 7:30 AM on Monday. We will set and check some camera traps daily, targeting different species and using different methods. After an afternoon break, we will return to the field in the late afternoon. Lectures and discussions will take place in the field or in the evening. The class will end at noon on Friday, July 22nd.  Please visit the Camera Trap Codger page for a more detailed itinerary.
