Pumas (Puma concolor) — also known as cougars, panthers or mountain lions — are big cats that can be very vocal. Acoustic recorders may capture sounds like cries and meows that help us understand how these animals communicate, but camera traps allow us to see their behavior.
In this camera trap photo, a puma drags what appears to be a howler monkey (Alouatta seniculus) through the forest. Pumas are known to hunt these monkeys, but records of this behavior are rare.
Howler monkeys (Alouatta seniculus) seldom come down to the forest floor, so we were lucky to capture them in one of our ground camera traps. They are known as the arboreal (or tree-dwelling) “cows” of the rainforest, because they eat a lot of leaves. Many mammals have difficulty digesting leaves, but like cows, howler monkeys have special adaptations in their guts that allow them to do so.
