The BBC says wild chimps have learned to detect and avoid traps set by human hunters

Across Africa, people often lay snare traps to catch bushmeat, killing or injuring chimps and other wildlife.

But a few chimps living in the rainforests of Guinea have learnt to recognise these snare traps laid by human hunters, researchers have found.

More astonishing, the chimps actively seek out and intentionally deactivate the traps, setting them off without being harmed.
