Enrichment is any practice where zookeepers give animals something new — from perches to toys to exotic foods and scents. The idea is to encourage captive animals to keep their wild behaviors sharp or give them a mental challenge, some exercise or just an interesting toy to investigate.
"We want our animals to be as natural as possible," said Smithsonian zookeeper Jenny Spotten. "We want to encourage natural behaviors as much as possible."
It's a bit avant-garde, yes, but a jam session can have real health benefits. Enrichment reduces stress, and makes zoo residents less likely to pick up unnatural behaviors, like pacing or swimming in circles.
And you have to admit that it's fun to listen to.
