Field biologists are increasingly turning to camera traps to collect data. The set-up is really simple: when an animal passes in front of a camera, an infrared sensor becomes activated, and the camera silently snaps a photo.

Ordeñana is a biologist with the Natural History Museum of Los Angeles. He’s an expert on camera traps [and] conducts field research on jaguars in Nicaragua.

According to Ordeñana, a Bronx Zoo researcher once tried a bunch of different scents and discovered that jaguars really liked the Calvin Klein [Obsession for Men] cologne.

“It has civetone and it has vanilla extract”, he says. “[W]e think is that the civetone resembles some sort of territorial marking to the jaguar, and so it responds by rubbing its own scent on it”.
