Telling one guiña from another: It's all about the angle

Researchers in Chile's Reñihué Valley identified 12 individual guiña cats using a novel camera-trap technique—angling cameras downward from tree branches to capture unique dorsal markings—enabling species population estimates previously impossible with ground-level imaging.

The technique is newly feasible but hasn't yet been deployed widely; its real-world impact on guiña conservation policy or population management remains to be demonstrated.
